Abstract
Over the last few decades, our understanding of the pathophysiology and natural history of sigmoid diverticulitis has greatly improved. This knowledge has challenged many of the traditional principles in the management for diverticulitis, such as routine antibiotic administration in all cases, number-based recommendations for elective surgery, and the necessity for an end colostomy in emergency surgery. This review will cover the breadth of management for sigmoid diverticulitis, covering both uncomplicated and complicated disease as well as elective and emergent disease presentations. New and emerging concepts in management will be highlighted with a particular focus on level-1 data, when available.

Abstract
INTRODUCTION Patients presenting with large bowel obstruction (LBO) frequently undergo emergency surgery that is associated with significant morbidity. In malignant LBO, endoscopic approaches with placement is a self-expanding metal stent (SEMS), have been proposed to prevent emergency surgery and act as a bridge to an elective procedure-with the intention of avoiding a stoma and reducing morbidity. This systematic review aims to assess the quality and outcomes of data available on the use of SEMS in benign causes of colonic obstruction. METHODS This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and the protocol was registered on Prospero (ID: CRD42021239363). PUBMED, MEDLINE, HMIC, CINAHL, AMED, EMBASE, APA and Cochrane databases were searched. Studies were assessed for quality utilising the MINORS criteria. Pooled odds ratios with 95% confidence intervals (95% CI) were calculated using random effects models. RESULTS Sixteen studies were included for analysis. 300 patients were included with an average age of 68, and a male predominance of 57%. The quality of the papers included were at risk of bias. The pooled rate of technical success of procedure was 94.4% (95% CI 90.5-96.8%) The pooled rate of clinical success was 77.6% (95% CI: 66.6-85.7%). Adverse effects were low, with perforation 8.8% (4.5-16.6%), recurrence 26.5% (17.2-38.5%) and stent migration 22.5% (14.1-33.8%). DISCUSSION This systematic review demonstrated that SEMS for benign colonic obstruction can be a safe and successful procedure. The utilisation of SEMS in malignant disease as a bridge to surgery has been well documented. Whilst the limitations of the data interpreted are appreciated, we postulate that SEMS could be utilised to decompress patients acutely and allow pre-operative optimisation, leading to a more elective surgery with less subsequent morbidity.

Abstract
Colonic stent placement is a commonly used bridging strategy for surgery in patients with obstructive colorectal cancer. The procedure involves the placement of a self-expandable metallic stent (SEMS) across the obstructive lesion to restore intestinal patency and alleviate the symptoms of obstruction. By allowing patients to receive surgery in a planned and staged manner with time for preoperative optimization and bowel preparation, stent placement may reduce the need for emergency surgery, which is associated with higher complication rates and poorer outcomes. This review focuses on the role of colon stenting as a bridge to surgery in the management of obstructive colorectal cancer. SEMS as a bridge to surgery for left-sided colon cancer has been demonstrated to be particularly useful; however, further research is needed for its application in cases of right-sided colon cancer. Colon stent placement also has limitations and potential complications including stent migration, re-obstruction, and perforation. However, the timing of curative surgery after SEMS placement remains inconclusive. Considering the literature to date, performing surgery at an interval of approximately 2 weeks is considered appropriate. Therefore, colonic stent placement may be an effective strategy as a bridge to surgery in patients with obstructive colorectal cancer.

Abstract
Diverticulosis and diverticulitis remain common diagnoses in western countries, and the incidence continues to rise. Diverticulitis accounts for roughly one-third of admissions to acute care hospitals annually, with even more patients being treated as outpatients due to improved understanding of risk stratification and the natural history of disease progression. Thus, having a thorough understanding of the etiology of the disease in conjunction with computed tomography findings and patient presentation can help dictate the appropriate treatment.

Abstract
Large bowel obstruction is a serious event that occurs in approximately 25% of all intestinal obstructions. It is attributed to either benign, malignant, functional (pseudo-obstruction), or mechanical conditions. Benign etiologies of colonic obstructions include colon volvulus, anastomotic strictures, radiation injury, ischemia, inflammatory processes such as Crohn's disease, diverticulitis, bezoars, and intussusception.

Abstract
BACKGROUND Endoscopic placement of a self-expandable metal stent (SEMS) is a minimally invasive treatment for use in malignant and benign colonic obstruction. However, their widespread use is still limited with a nationwide analysis showing only 5.4% of patients with colon obstruction undergoing stent placement. This underutilization could be due to perceived increase risk of complications with stent placement.
AIM To review long- and short-term clinical success of SEMS use for colonic obstruction at our center.
METHODS We retrospectively reviewed all the patients who underwent colonic SEMS placement over a eighteen year period (August 2004 through August 2022) at our academic center. Demographics including age, gender, indication (malignant and benign), technical success, clinical success, complications (perforation, stent migration), mortality, and outcomes were recorded.
RESULTS Sixty three patients underwent colon SEMS over an 18-year period. Fifty-five cases were for malignant indications, 8 were for benign conditions. The benign strictures included diverticular disease stricturing (n = 4), fistula closure (n = 2), extrinsic fibroid compression (n = 1), and ischemic stricture (n = 1). Forty-three of the malignant cases were due to intrinsic obstruction from primary or recurrent colon cancer; 12 were from extrinsic compression. Fifty-four strictures occurred on the left side, 3 occurred on the right and the rest in transverse colon. The total malignant case (n = 55) procedural success rate was 95% vs 100% for benign cases (P = 1.0, NS). Overall complication rate was significantly higher for benign group: Four complications were observed in the malignant group (stent migration, restenosis) vs 2 of 8 (25%) for benign obstruction (1-perforation, 1-stent migration) (P = 0.02). When stratifying complications of perforation and stent migration there was no significant difference between the two groups (P = 0.14, NS).
CONCLUSION Colon SEMS remains a worthwhile option for colonic obstruction related to malignancy and has a high procedural and clinical success rate. Benign indications for SEMS placement appear to have similar success to malignant. While there appears to be a higher overall complication rate in benign cases, our study is limited by sample size. When evaluating for perforation alone there does not appear to be any significant difference between the two groups. SEMS placement may be a practical option for indications other that malignant obstruction. Interventional endoscopists should be aware and discuss the risk for complications in setting of benign conditions. Indications in these cases should be discussed in a multi-disciplinary fashion with colorectal surgery.

Abstract
BACKGROUND/AIMS Endoscopic stenting is an evolving treatment for symptomatic Crohn's strictures. Several case series and small studies have reported its efficacy. Future studies can be designed based on a systematic review of the evaluation of efficacy. Hence, this meta-analysis was conducted to assess the critical role of stents in the management of intestinal strictures associated with Crohn's disease (CD). METHODS A literature search of various databases from 2000 to February 2022 was conducted for studies evaluating the outcome of stents in patients with CD-related stricture. The outcomes assessed included technical and clinical success, adverse events, symptom recurrence, and the need for a surgical resection. Pooled event rates across studies were expressed with summative statistics. RESULTS Ten studies with 170 patients were included in the present analysis. The pooled event rates for technical success, clinical success, stent migration, and post-procedural pain were 98.2% (95% CI, 95.8-100), 71.3% (95% CI, 57.4-85.1), 32% (95% CI, 0.0-65.3) and 20.2% (95% CI, 4.1-36.2), respectively. The cumulative recurrence rate and need for surgery were 40.1% (95% CI, 20.3-59.9) and 8.6% (95% CI, 1.7-15.5), respectively. Subgroup analysis showed that partially-covered (PC) self-expanding metallic stent (SEMS) was significantly better than fully-covered SEMS with a lower stent migration rate and symptom recurrence rate. CONCLUSIONS Overall efficacy of stents in the management of CD-related stricture remains moderate with a low complication rate. Among the stents, PC-SEMS may be associated with a more favorable outcome. Future studies will be needed to determine the long-term benefits of endoscopic stenting.

Abstract
Colonoscopy is a crucial diagnostic tool in managing diverticular disease (DD). Diverticulosis can often be an unexpected diagnosis when colonoscopy is performed in asymptomatic subjects, generally for colorectal cancer screening, or it could reveal an endoscopic picture compatible with DD, including acute diverticulitis, in patients suffering from abdominal pain or rectal bleeding. However, alongside its role in the differential diagnosis of colonic diseases, particularly with colon cancer after an episode of acute diverticulitis or segmental colitis associated with diverticulosis, the most promising use of colonoscopy in patients with DD is represented by its prognostic role when the DICA (Diverticular Inflammation and Complication Assessment) classification is applied. Finally, colonoscopy plays a crucial role in managing diverticular bleeding, and it could sometimes be used to resolve other complications, particularly as a bridge to surgery. This article aims to summarize "when" to safely perform a colonoscopy in the different DD settings and "why".

Abstract
PURPOSE Aim of our study was to evaluate the outcomes of a consecutive series of patients who were treated with a decompressing colostomy (DC) for acute left-sided colorectal obstruction. METHOD A consecutive series of 100 patients with acute left-sided colorectal obstruction who underwent DC from January 2015 to August 2020 was retrospectively analyzed. Demographic characteristics, etiology of the obstruction, postoperative morbidity- and mortality rates, DC-related complication and stoma reversal rates were evaluated. RESULTS Of the 100 included patients, 64 had malignant- and 36 had benign obstruction. The mean age was 69 years, 42% was male, and the ASA score was 2. Morbidity and mortality rates after DC construction were 20 and 2%, respectively. In 39% of the patients, DC ended up as a permanent stoma and in 61% as bridge to surgery (BtS). DC related complication rate was 32%, with a re-intervention rate of 9%. Elective colorectal resection was performed in 59 cases (59%) with subsequent postoperative morbidity rate of 20%. Stoma reversal rate was 77% for the patients who underwent DC as BtS. Stoma reversal was performed in 66% of the patients with benign obstruction and in 36% for oncological obstruction. CONCLUSION DC as bridge to possible elective resection for acute left-sided colorectal obstruction is an effective strategy with low morbidity and mortality rates and a high stoma reversal rate, especially for benign obstruction. However, DC is less appropriate for patients in whom DC turns out to be a permanent stoma due to a relatively high stoma related complications.

Abstract
BACKGROUND The incidence of colonic stenosis, primarily caused by colon cancer and Crohn's disease, is increasing each year. The development of safer stents for colonic stenosis is required because perforation associated with cancer stent placement worsens the prognosis and stent placement for anastomotic stenosis due to Crohn's disease or colectomy is not first choice due to the high migration rate. The wall of the large intestine where the stent is inserted receives the complex forces from the peristaltic movement of the large intestine and stool in addition to the reaction tension of the stent, causing perforation and migration. Animal models may help develop new and safe stents, but no animal model closely reproduces the condition of human colonic stenosis. Herein, we present a novel animal model of colonic stenosis, which closely replicates the human colonic size. METHODS The artificial colonic stenosis model was developed by wrapping the porcine colon with a silicone sheet after laparotomy. The usefulness of the model was evaluated by investigating the availability of endoscopic stent placement, morphological maintenance of colonic stenosis, adverse effects on pigs, and modeling time. The first three and the last three modeling times were analyzed using Student's t-test. RESULTS Endoscopic stent placement was performed in all cases without intraoperative complications. There were no postoperative model complications or deaths. Adhesions to the surrounding tissue in the abdominal cavity of the artificial colon stenosis were slight. The morphology of the isolated artificial stenoses was completely maintained, and no necrosis or perforation was observed. CONCLUSIONS We developed a novel and feasible animal model of colonic stenosis using pigs. We believe that this animal model will be useful for developing a safer stent for obstruction caused by benign diseases and colon cancer.

Abstract
BACKGROUND Colonic stent placement can avoid urgent surgery for large bowel obstruction in selected patients. Population-wide stent utilization patterns and outcomes are unknown. MATERIALS AND METHODS Using retrospective, population-based, Nationwide Inpatient Sample data, we studied patients with colonic stents discharged during 2010-2015. The primary outcome was ostomy creation during the same hospitalization. Other outcomes were perforation or peritonitis, and in-hospital death. Associations of outcomes with stent indication were investigated, adjusting for patient-, admission-, and hospital characteristics. We estimated annual population-wide stent use volumes. RESULTS Of 4257 patients with stent placement (52% male, mean age 64.6 years), 9.9% had non-metastatic colon cancer, 12.9% metastatic colon cancer, 37.8% extracolonic malignancy (ECM), and 39.3% had benign obstruction. In 8.1% of patients, ostomy creation surgery was performed. Perforation or peritonitis occurred in 16.7%, and in-hospital death in 4.5%. Relative to ECM, ostomy creation was several-fold more likely among nonmetastatic colon cancer (adjusted odds ratio (OR) 3.4; 95%CI, 2.1-5.5), metastatic colon cancer (adjusted OR 2.5; 95%CI, 1.7-3.7), and benign obstruction patients (adjusted OR 3.1; 95%CI, 2.1-4.7). Benign obstruction was associated with high risk of perforation/peritonitis (adjusted OR 3.1 relative to non-metastatic CC (95%CI, 2.1-4.5)). Perforation/peritonitis was highly associated with inpatient death (adjusted OR 6.8 (95%CI, 4.9-9.5)). Annually, about 3,580 patients underwent stent placement, with benign obstruction showing an increasing trend (P=0.0002). CONCLUSIONS Over 75% of stent placements were done for patients with benign disease and ECM obstruction. Subsequent ostomy creation during the hospitalization was least likely among ECM patients. Rates of perforation/peritonitis in benign obstructions were concerningly high. (22.2%).

Abstract
OBJECTIVE Fibrotic strictures in the gastrointestinal tract are frequent in Crohn's disease. Endoscopic dilation is a standard treatment. However, recurrence is common after dilation and there are complications such as bleeding or perforation. Endoscopic treatment using self-expandable metal stents has shown diverging results. The aim of this study was to evaluate the outcome of endoscopic treatment with a self-expandable stent in ileocecal Crohn's disease. DESIGN/METHOD Patients with Crohn's disease and a symptomatic ileocecal stricture were eligible for prospective, consecutive inclusion in a single-centre setting. Patients were randomised to treatment with either 18 mm balloon dilatation (GroupDIL) or stenting (GroupSTENT) using a 20 mm diameter, partially covered Hanarostent NCN. Patients were followed for a minimum of 24 months postendoscopy. Outcomes were technical success, adverse events and clinical success (defined as no need for repeated interventions). RESULTS Thirteen patients (GroupDIL n=6; GroupSTENT=7) were included with twelve patients (GroupDIL n=5; GroupSTENT=7) being eligible for complete follow-up. Technical success was achieved in all cases. Adverse events were border-line significantly more common in the GroupSTENT: 4/7 (57%) (pain: n=3; pain and rectal bleeding: n=1) compared with the GroupDIL: 0/5 (0%), p=0.08, which resulted in preterm termination of the study. The clinical success rate was GroupSTENT: 6/7 (86%) vs GroupDIL: 1/5 (20%), p=0.07. CONCLUSION Patients with strictures related to Crohn's disease may benefit from treatment with self-expandable metal stents rather than dilatation. However, there seems to be an increased risk for patient pain after stenting, which has to be considered and handled. TRAIL REGISTRATION NUMBER The study was registered at Clinical Trials (NCT04718493).

Abstract
Traditionally, management of complicated diverticular disease has involved open damage control operations with large definitive resections and colostomies. Studies are now showing that in a subset of patients who would typically have undergone an open Hartmann's procedure for Hinchey III/IV diverticulitis, a laparoscopic approach is equally safe, and has better outcomes. Similar patients may be good candidates for primary anastomosis to avoid the morbidity and subsequent reversal of a colostomy. While most operations for diverticulitis across the country are still performed open, there has been an incremental shift in practice toward minimally invasive approaches in the elective setting. The most recent data from large trials, most notably the SIGMA trial, found laparoscopic sigmoid colectomy is associated with fewer short-term and long-term complications, decreased pain, improvement in length of stay, and maintains better cost-effectiveness than open resections. Some studies even demonstrate that robotic sigmoid resections can maintain a similar if not more reduction in morbidity as the laparoscopic approach while still remaining cost-effective. Intraoperative approaches also factor into improving outcomes. One of the most feared complications in colorectal surgery is anastomotic leak, and many studies have sought to find ways to minimize this risk. Factors to consider to minimize incidence of leak are the creation of tension-free anastomoses, amount of contamination, adequacy of blood supply, and a patient's use of steroids. Techniques supported by data that decrease anastomotic leaks include preoperative oral antibiotic and mechanical bowel prep, intraoperative splenic flexure mobilization, low-tie ligation of the inferior mesenteric artery, and use of indocyanine green immunofluorescence to assess perfusion. In summary, the management of benign diverticular disease is shifting from open, morbid operations for a very common disease to a minimally invasive approach. In this article, we review those approaches shown to have better outcomes, greater patient satisfaction, and fewer complications.

Abstract
Diverticula are the most common incidental finding during routine colonoscopy, and their prevalence increases with patient age. The term “diverticular disease” encompasses the range of clinical manifestations and complications that can occur with colonic diverticula, including diverticular bleeding, diverticulitis-associated strictures, and acute diverticulitis. Colonoscopy is a vital tool in the diagnosis and management of diverticular disease and can be useful in a variety of regards. In this editorial, we concisely delineate the current approach to and practices in colonoscopic management of diverticular disease. In particular, we discuss treatment options for diverticular bleeding, propose consideration of colonic stenting as a bridge to surgery in patients with diverticulitis-associated strictures, and the need for diagnostic colonoscopy following an episode of acute diverticulitis in order to rule out underlying conditions such as colonic malignancy or inflammatory bowel disease. In addition, we offer practical tips for performing safe and successful colonoscopy in patients with dense diverticulosis coli.

Abstract
In recent years, self-expandable metal stents (SEMSs) have been employed to treat benign gastrointestinal strictures secondary to several conditions: Acute diverticulitis, radiation colitis, inflammatory bowel disease (IBD), and postanastomotic leakages and stenosis. Other applications include endometriosis and fistulas of the lower gastrointestinal tract. Although it may be technically feasible to proceed to stenting in the aforementioned benign diseases of the lower gastrointestinal tract, the outcome has been reported to be poor. In fact, in some settings (such as complicated diverticulitis and postsurgical anastomotic strictures), stenting seems to have a limited evidence-based benefit as a bridge to surgery, while in other settings (such as endometriosis, IBD, radiation colitis, etc.), even society guidelines are not able to guide the endoscopist through decisional algorithms for SEMS placement. The aim of this narrative paper is to review the scientific evidence regarding the use of SEMSs in nonmalignant diseases of the lower gastrointestinal tract, both in adult and pediatric settings.

Abstract
There are a variety of causes of intestinal obstruction, with the most common cause being malignant diseases; however, volvulus, inflammatory bowel disease or diverticulitis, radiation injury, ischemia, and pseudo-obstruction can also cause colonic obstruction. These are benign conditions; however, delayed diagnosis of acute intestinal obstruction owing to these causes can cause critical complications, such as perforation. Therefore, high levels of clinical suspicion and appropriate treatment are crucial. There are variable treatment options for colonic obstruction, and endoscopic treatment is known to be a less invasive and an effective option for such. In this article, the authors review the causes of benign colonic obstruction and pseudo-obstruction and the role of endoscopy in treating them.

Abstract
In recent years, endoscopic placement of intraluminal stents is increasingly used to manage a widening range of colorectal disorders. Self-expanding metal stents represent an established alternative to surgery for the palliation of unresectable carcinomas and currently allow a "bridge-to-surgery" strategy to relieve large bowel obstruction and optimise the patients' clinical conditions before elective oncologic resection. Additionally, intraluminal stents represent an appealing option to manage obstructing extracolonic tumours and selected patients with benign conditions such as refractory anastomotic strictures and post-surgical leaks.This educational paper reviews the technical features and current indications of colorectal stenting and presents the expected and abnormal radiographic, CT and MRI appearances observed during the endoscopic management of malignant, benign and iatrogenic colonic disorders with stents. The aim is to provide radiologists with a thorough familiarity with stent-related issues, which is crucial for appropriate reconstruction of focused CT images, correct interpretation of early post-procedural studies and elucidation of stent-related complications such as misplacement, haemorrhage, perforation, migration and re-obstruction.

Abstract
Background and study aims Placement of a fully-covered self-expanding metal stent (FC-SEMS) is a valid alternative for benign and malignant colorectal strictures treatment. Despite the reportedly high technical success rate, stenting is still challenging, due to high rates of adverse events. Migration still represents the main issue, although several anti-migration systems have been proposed. Patients and methods Before insertion, esophageal Beta Niti-S FC-SEMSs were inverted and reloaded on the deployment device to invert the proximal and distal parts of the stent, with the largest end placed above the stricture to contrast peristaltic activity. The inverted "upside-down" Beta Niti-S FC-SEMS was placed in five consecutive patients: four pts with benign anastomotic stricture unresponsive to repeated balloon dilation and persisting for at least 10 weeks, and one with malignant rectal neoplasia. In five patients, six inverted FC-SEMSs were placed. Results The modified FC-SEMS did not migrate in 5/6 cases (83 %). Stent migration occurred in the neoplastic case, induced by neoadjuvant chemotherapy. The "upside-down" esophageal Beta Niti-S FC-SEMS stayed in place for an average of 6 weeks, achieving resolution of stricture in all patients but one, who required an additional stent placement, due to incomplete stricture resolution after 6 weeks. Conclusion The inverted esophageal Beta Niti-S FC-SEMSs proved to be effective in treating colorectal stricture in all cases, with no spontaneous migration or significant side effects, and achieved resolution of strictures where a traditional approach, recommended by guidelines, failed.

Abstract
Objective Recurrent acute diverticulitis carries a major burden to any form of health care. Patients present repeatedly to medical centers with a multitude of symptoms and may require different modalities of treatment with significant morbidities and impact on quality of life. Methods We therefore wanted to identify factors that would imply the need and time of surgery versus conservative management. The literature was thoroughly searched for major studies tackling this topic. Furthermore, studies reporting on decision making based on quality of life were included. Risks of developing recurrent diverticulitis and the potential need of surgery were identified. Relevant surgical details that would decrease recurrence were also denoted. Results Surgery has been the mainstay of treatment for quite some time. However, the paradigms of treatment have changed over the last few years, especially when long-term population studies confirmed that not all patients require surgical treatment with its associated risk of morbidity. Conclusion Treatment now has to be patient-tailored with special attention to the subgroup of high-risk patients. These patients must be adequately selected, identifying the impact of the disease on the quality of life and weighing in the risks of the surgical intervention.

Methodological overview of systematic reviews to establish the evidence base for emergency general surgery. Br J Surg 2017; 104:513-524. [PMID: 28295254 PMCID: PMC5363346 DOI: 10.1002/bjs.10476] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Revised: 08/23/2016] [Accepted: 11/30/2016] [Indexed: 12/18/2022]
Abstract
BACKGROUND The evidence for treatment decision-making in emergency general surgery has not been summarized previously. The aim of this overview was to review the quantity and quality of systematic review evidence for the most common emergency surgical conditions. METHODS Systematic reviews of the most common conditions requiring unplanned admission and treatment managed by general surgeons were eligible for inclusion. The Centre for Reviews and Dissemination databases were searched to April 2014. The number and type (randomized or non-randomized) of included studies and patients were extracted and summarized. The total number of unique studies was recorded for each condition. The nature of the interventions (surgical, non-surgical invasive or non-invasive) was documented. The quality of reviews was assessed using the AMSTAR checklist. RESULTS The 106 included reviews focused mainly on bowel conditions (42), appendicitis (40) and gallstone disease (17). Fifty-one (48·1 per cent) included RCTs alone, 79 (74·5 per cent) included at least one RCT and 25 (23·6 per cent) summarized non-randomized evidence alone. Reviews included 727 unique studies, of which 30·3 per cent were RCTs. Sixty-five reviews compared different types of surgical intervention and 27 summarized trials of surgical versus non-surgical interventions. Fifty-seven reviews (53·8 per cent) were rated as low risk of bias. CONCLUSION This overview of reviews highlights the need for more and better research in this field.

Abstract
Endoscopic balloon dilatation (EBD) is a recognised treatment for symptomatic Crohn's disease strictures. Over 3000 procedure are reported in the literature and yet the long term benefits are unclear. This is largely because of different populations, study designs, techniques, types of strictures, the outcome measures used and follow-up periods. Areas covered: We summarised the techniques reported in the literature based on a systematic review and key factors that may influence outcome: pre-intervention imaging, stricture length and type, balloon size in relation to intestinal lumen diameter, duration of dilatation, frequency of repeat dilatation and instructions on follow-up. Expert commentary: We noted that shorter, non-ulcerated and anastomotic strictures fare better and 2 mins dilatation duration was the commonest technique used without an increased risk of complications. The findings were translated into a standardised protocol and a management pathway to guide clinicians on the therapeutic strategy for Crohn's strictures. To resolve the uncertainty about long-term benefits, future studies should adopt a replicable standardised EBD technique, define degree of fibrosis to decide therapy accordingly, compare it to alternative interventions (strictureplasty or stents) within a randomised controlled trial and apply a validated outcome measure to include intestinal damage and quality of life.

Abstract
AIMS To assess the factors contributing to the technical and clinical success of colorectal stenting for large bowel obstruction. METHODOLOGY 268 cases of colonic stenting for large bowel obstruction were performed in 249 patients of mean age of 72 years (28-98) between 2006 and 2013. The majority of strictures were due to malignant disease, 244/268 (91 %). Diverticular strictures accounted for 24/268 (9 %). RESULTS Overall technical success rate was 81 % (217/268), with a clinical success rate of 65 % (174/268). Duration of symptoms ranged from 0 to 180 days (mean 8 days). Technical success rate was seen to decrease with increasing symptom duration. For symptom duration of less than 1 week, technical success was 85.4 % (181/212) versus 69.6 % (39/56) for those with symptoms of greater than a week (p < 0.05). Clinical success rates fell from 71.3 % (107/150) to 59.3 % (70/118) (p < 0.05) when attempting to stent lesions of greater than 5 cm. There was also a significant reduction in clinical success when stenting lesions on a bend rather than a straight segment of colon 75.7 % (109/144) versus 59.7 % (74/124) (p < 0.05). A total of 20 (7.46 %) perforations were identified during the study. Stent migration occurred in 6.6 % of cases. In-stent stenosis occurred in 3.3 %. The overall 30-day all cause mortality rate was 9 %. CONCLUSION Lesion size, location and duration of obstructive symptoms are statistically significant determinants of patient outcome. These factors could be used to advise patient selection for colonic stenting or direct progression to surgical intervention.

Abstract
PURPOSE To clarify the advantages and disadvantages of stenting as a bridge to surgery (BTS) by comparing the clinical features and outcomes of patients who underwent BTS with those of patients who underwent emergency surgery (ES). METHODS We assessed technical success, clinical success, surgical procedures, stoma formation, complications, clinicopathological features, and Onodera's prognostic nutritional index (OPNI) in patients who underwent BTS and those who underwent ES. RESULTS Twenty-six patients underwent stenting, which was successful in 22 (BTS group). The remaining four patients with unsuccessful stenting underwent emergency surgery. A total of 22 patients underwent emergency surgery (ES group). The rates of technical and clinical success were 85.0 and 81.0 %, respectively. The proportion of patients able to be treated by laparoscopic surgery (P = 0.0001) and avoid colostomy (P = 0.0042) was significantly higher in the BTS group. Although the incidence of anastomotic leakage in the two groups was not significantly different, it was significantly reduced by colonoscopic evaluation of obstructive colitis (P = 0.0251). The mean number of harvested lymph nodes (P = 0.0056) and the proportion of D3 lymphadenectomy (P = 0.0241) were significantly greater in the BTS group. Perineural invasion (PNI) was noted in 59.1 and 18.2 % of the BTS group and ES group patients, respectively (P = 0.0053). OPNI and serum albumin decreased significantly after stenting (P = 0.0084). CONCLUSIONS The advantages of stenting as a BTS were that it avoided colostomy and allowed for laparoscopic surgery and lymphadenectomy, whereas its disadvantage lay in the decreased PNI and OPNI levels. A larger study including an analysis of prognosis is warranted.

Abstract
Colorectal cancer is one of the commonly encountered cancers across the Western World. In United Kingdom, this constitutes third most common ranked cancer and second most common ranked cause of cancer related deaths. Its acute presentation as a malignant colonic obstruction imposes challenges in its management. Colonic stent has been used for many years to alleviate acute obstruction in such cases allowing optimisation of patient's physiological status and adequate staging of cancer. In this review, current literature evidence regarding use of colonic stent in acute malignant colonic obstruction is critically appraised and recommendations on the use of colonic stent are advocated.

Abstract
AIM There are currently no available simulation models for training in colonoscopic stent deployment. The aim of this study was to validate a cadaver model for simulation training in colonoscopy with stent deployment for colonic strictures. METHOD This was a prospective study enrolling surgeons at a single institution. Participants performed colonoscopic stenting on a cadaver model. Their performance was assessed by two independent observers. Measurements were performed for quantitative analysis (time to identify stenosis, time for deployment, accuracy) and a weighted score was devised for assessment. The Mann-Whitney U-test and Student's t-test were used for nonparametric and parametric data, respectively. Cohen's kappa coefficient was used for reliability. RESULTS Twenty participants performed a colonoscopy with deployment of a self-expandable metallic stent in two cadavers (groups A and B) with 20 strictures overall. The median time was 206 s. The model was able to differentiate between experts and novices (P = 0. 013). The results showed a good consensus estimate of reliability, with kappa = 0.571 (P < 0.0001). CONCLUSION The cadaver model described in this study has content, construct and concurrent validity for simulation training in colonoscopic deployment of self-expandable stents for colonic strictures. Further studies are needed to evaluate the predictive validity of this model in terms of skill transfer to clinical practice.

Abstract
A self-expandable metal stent (SEMS) is an effective and safe method for the decompression of colon obstruction. Based on recent evidence, colorectal SEMS is now recommended for the palliation of patients with colonic obstruction from incurable colorectal cancer or extracolonic malignancy and also as a bridge to surgery in those who are a high surgical risk. Prophylactic SEMS insertion in patients with no obstruction symptoms is not recommended. Most colorectal SEMS are inserted endoscopically under fluoroscopic guidance. The technical and clinical success rates of colorectal SEMS are high, and the complication rate is acceptable. Advances in this technology will make the insertion of colorectal SEMS better and may expand the indications of colorectal SEMS in the future.

Abstract
Introduction. Colorectal anastomotic leak or stricture is a dreaded complication leading to significant morbidity and mortality. The novel use of self-expandable metal stents (SEMS) in the management of postoperative colorectal anastomotic leaks or strictures can avoid surgical reintervention. Methods. Retrospective study with particular attention to the indications, operative or postoperative complications, and clinical outcomes of SEMS placement for patients with either a colorectal anastomotic stricture or leak. Results. Eight patients had SEMS (WallFlex stent) for the management of postoperative colorectal anastomotic leak or stricture. Five had a colorectal anastomotic stricture and 3 had a colorectal anastomotic leak. Complete resolution of the anastomotic stricture or leak was achieved in all patients. Three had recurrence of the anastomotic stricture on 3-month flexible sigmoidoscopy follow-up after the initial stent was removed. Two of these patients had a stricture that was technically too difficult to place another stent. Stent migration was noted in 2 patients, one at day 3 and the other at day 14 after stent placement that required a larger 23 mm stent to be placed. Conclusions. The use of SEMS in the management of colorectal anastomotic leaks or strictures is feasible and is associated with high technical and clinical success rate.
