Solid pseudopapillary neoplasms (SPN) of the pancreas are rare pancreatic neoplasms where complete resection is the cornerstone in management. It has been demonstrated in previous studies that minimally invasive surgical approaches are effective management options in treating SPNs of the distal pancreas. The purpose of this study is to evaluate the feasibility of minimally invasive surgery in treating SPNs of the uncinate, head, and neck of the pancreas.

Data from 2005 to 2017 at Severance Hospital of the Yonsei University Health systems in Seoul, South Korea, were retrospectively collected for 25 patients who were diagnosed with SPN of the uncinate, head, and neck of the pancreas and who underwent curative resection. Three groups of patients were considered, depending on the year of surgery, in order to determine trends in the surgical management of SPN. The patients were also divided into two groups corresponding to the type of operation done (minimally invasive surgery vs. open surgery). Perioperative patient data, including age, gender, body mass index (BMI), tumor size, and operation done, were compared and analyzed statistically. Long-term nutritional effects were measured using the Controlling Nutritional Status (CONUT) scoring system.

There were no statistically significant differences in age, gender, BMI, symptomatic presentation, operation type, tumor size, and tumor stage between the three time periods. In comparing between minimally invasive and open surgery, there were no statistically significant differences in age, gender, symptomatic presentation, BMI, tumor size, preoperative stage, type of operation, operation time, pancreatic duct size, post-operative pancreatic fistula (POPF) grade, death associated with disease, recurrence, pathological parameters, and change in CONUT score. There was a significant difference in tumor size (4.5 ± 1.8 vs. 2.6 ± 1.0 cm, p = 0.004), blood loss (664.2 ± 512.4 vs. 277.7 ± 250.8 mL, p = 0.024), need to transfuse (33% vs. 0%, p = 0.023), hospital length of stay (27.4 ± 15.3 vs. 11.5 ± 5.3 days, p = 0.002), and complication rate (75% vs. 30.8%, p = 0.027) between the two groups.

In appropriately selected patients with SPNs of the uncinate, head, and neck of the pancreas, a minimally invasive surgical approach offers at least equal oncologic and nutritional outcomes, while demonstrating decreased complications and decreased hospital length of stay compared with that of an open surgical approach.

Pancreatic fistula/PF is the most frequent and feared complication after distal pancreatectomy/DP. However, the safest technique of pancreatic stump closure remains an ongoing debate. Here, we aimed to compare the safety of different pancreatic stump closure techniques for preventing PF during DP.

We performed a PRISMA-based meta-analysis of all relevant studies that compared at least two techniques of stump closure during DP with regard to PF rates/PFR. We further performed a retrospective analysis of our institutional PFR in correlation with stump closure techniques.

8301 studies were initially identified. From these, ten randomized controlled trials/RCTs, eleven prospective and 59 retrospective studies were eligible. Stapler closure (26%vs.31%, OR:0.73, p = 0.02), combination of stapler and suture (30%vs.33%, OR:0.70, p = 0.05), or stump anastomosis (14%vs.28%, OR:0.51, p = 0.02) were associated with lower PFR than suture closure alone. Spleen preservation/splenectomy, or laparoscopic/open DP, TachoSil^®, fibrin-like glue-application, or bioabsorbable-stapler-reinforcements (Seamguard^®) did not influence PFR after DP. In contrast, autologous patches (falciform ligament/seromuscular patches) resulted in lower PFR than no patch application (21.9%vs.25,8%, OR:0.60, p = 0.006). In our institution, the major three techniques of stump closure resulted in comparable PFR (suture:27%, stapler:29%, or combination:24%). However, selective suturing/clipping of the main pancreatic duct during pancreatic stump closure prevented severe PF (p = 0.02).

After DP, stapler closure, pancreatic anastomosis, or falciform/seromuscular patches lead to lower PFR than suture closure alone. However, the differences are rather small, and further RCTs are needed to test these effects. Selective closure of the main pancreatic duct during stump closure may prevent severe PF.

Solid pseudopapillary pancreatic neoplasia is usually a large well-circumscribed pancreatic mass, with cystic and solid areas more frequently found in young women. It is a benign pancreatic neoplasia in most cases, therefore minimally invasive surgery could be an interesting approach.

Evaluate the results of minimally invasive surgery for this neoplasia.

Patients with this tumor who underwent minimally invasive pancreatectomies between 2009 and 2015 in a single institution, were analyzed regarding demographic, clinical-pathological futures, post-operative morbidity and disease-free survival.

All were women, and their median age was 39 (18-54) years. Two patients with tumor in the head of the pancreas underwent laparoscopic pancreaticoduodenectomy, and another one underwent laparoscopic enucleation. Two patients with tumor in the neck underwent central pancreatectomy. Distal pancreatectomies were performed in the other five, one with splenic preservation. None required blood transfusion or conversion to open surgery. Two (20%) developed clinical relevant pancreatic fistulas, requiring readmission. Median length of postoperative hospital stay was five days (2-8). All resection margins were negative. Patients were followed for a median of 38 months (14-71), and there was no recurrence.

Minimally invasive surgery for solid pseudopapillary pancreatic neoplasia is feasible for tumors in different locations in the pancreas. It was associated with acceptable morbidity and respected the oncologic principles for treatment.

Background. Solid Pseudopapillary Tumours of the pancreas are a rare entity and more commonly seen in women than in men. These tumours have typically reached large sizes when clinically detected. Case Description. A 21-year-old male was found to have a left hypochondrial mass on physical examination following a trivial soft tissue injury. Contrast-enhanced computed topography (CT) of the abdomen showed a 10.3 × 7.6 × 10.3 cm size arising from the body and the tail of the pancreas. He underwent laparoscopic resection of distal pancreatic tumour en bloc with spleen. Large tumour was noted originating from the body and tail of the pancreas with dilated veins surrounding the tumour. Histology revealed a clear cell variant of solid pseudopapillary neoplasm with steatotic pattern. Resection margin was free of tumour. Discussion. Several studies have shown significant short term advantages using laparoscopic approach compared to open surgery, in terms of lower blood loss, resumption of oral intake, and hospital stay. This case and few other case reports published in world literature have shown that laparoscopic approach is safe and oncologically adequate.

AIM: To assess the efficacy and safety of intracorporeal esophagojejunostomy in patients undergoing laparoscopic total gastrectomy (LTG) for gastric cancer.

METHODS: A retrospective review of 81 consecutive patients who underwent LTG with the same surgical team between November 2007 and July 2014 was performed. Four types of intracorporeal esophagojejunostomy using staplers or hand-sewn suturing were performed after LTG. Data on clinicopatholgoical characteristics, occurrence of complications, postoperative recovery, anastomotic time, and operation time among the surgical groups were obtained through medical records.

RESULTS: The average operation time was 288.7 min, the average anastomotic time was 54.3 min, and the average estimated blood loss was 82.7 mL. There were no cases of conversion to open surgery. The first flatus was observed around 3.7 d, while the liquid diet was started, on average, from 4.9 d. The average postoperative hospital stay was 10.1 d. Postoperative complications occurred in 14 patients, nearly 17.3%. However, there were no cases of postoperative death.

CONCLUSION: LTG performed with intracorporeal esophagojejunostomy using laparoscopic staplers or hand-sewn suturing is feasible and safe. The surgical results were acceptable from the perspective of minimal invasiveness.

Laparoscopic distal pancreatectomy (LDP) showed advantage of perioperation outcomes for benign and low-grade tumor of the pancreas. The application of LDP for pancreatic ductal adenocarcinoma (PDAC) didn’t gain popular acceptance and the number of LDP for PDAC remains low. We designed a case-matched study to analysis the short- and long-term outcomes of the patients undergoing either Laparoscopic distal pancreatectomy or open distal pancreatectomy for PDAC.

From 2003 to 2013, 17 patients were underwent LDP and 34 patients were underwent ODP for PDAC were matched by tumor size, age and body mass index (BMI). The two groups’ demographic information, perioperative outcomes and survival data were compared.

Baseline characteristics were comparable between the LDP and ODP groups. The intraoperative blood loss, first flatus, first oral intake and postoperative hospital stay were significantly less in LDP group than ODP group (50 ml vs400ml, P = 0.000; 3d vs 4d, P = 0.001; 3d vs 4d, P = 0.003; 13d vs 15.5d, P = 0.022). The mean operation time, overall postoperative morbidity and postoperative pancreatic fistula rates were similar in the two groups. 5 patients (29.4 %) in LDP group and 7 patients (20.6 %) in ODP group underwent extended resections. There were no significant differences in tumor sizes (3.5 cm vs 3.9 cm, P = 0.664) and number of harvested lymph nodes (9 vs8 P = 0.534). The median overall survival for both groups was 14.0 months. Cox proportional hazards analysis showed extended resections, R1 resection, perineural invasion and tumor differentiation were associated with worse survival.

LDP is technically feasible and safe for PDAC in selected patients and the short-term oncologic outcomes were not inferior to ODP in this small sample study. However the long-term oncologic safety of LDP for PDAC has to be further evaluated by multicenter or randomized controlled trials.

Some laterally advanced cholangiocarcinomas behave as ductal spread or local invasion, and hepatopancreatoduodenectomy (HPD) may be performed for R0 resection. To date, there have been no reports of laparoscopic HPD (LHPD) in the English literature. We report the first case of LHPD for the resection of a Bismuth IIIa cholangiocarcinoma invading the duodenum. The patient underwent laparoscopic pancreaticoduodenectomy and right hemihepatectomy. Child’s approach was used for the reconstruction. The patient recovered well with bile leakage from the 2^nd postoperative day and was discharged on the 16^th postoperative day with a drainage tube in place which was removed 2 wk after discharge. Postoperative pathology revealed a well-differentiated cholangiocarcinoma and the margin of liver parenchyma, pancreas and stomach was negative for metastases. The results suggest that LHPD is a feasible and safe procedure when performed in highly specialized centers and in suitable patients with cholangiocarcinoma.

Immunoglobulin G4 (IgG4)-associated disease is a recently recognized disease entity that is characterized by elevated serum IgG4 concentrations, abundant IgG4 lymphoplasmacytic infiltration, and dramatic steroid responses. IgG4-associated cholangitis is one manifestation of IgG4-associated disease. However, it is clinically challenging to make a preoperative differentiation between this rare disease and cholangiocarcinoma, especially for those with serum concentrations of IgG4 in the normal range. This article reports on a 57-year-old man with jaundice and upper abdominal discomfort. Imaging examination showed biliary stricture that closely resembled cholangiocarcinoma, and the patient’s serum IgG4 concentration was normal. The patient underwent a laparoscopic choledochectomy with Roux-en-Y hepaticojejunostomy using an intracorporeal hand-sewn technique. He recovered quickly without any complications. We also present our experience in laparoscopic intracorporeal hand-sewn hepaticojejunostomy.

Gastric cancer in remnant stomach is a rare tumor but with poor prognosis. Compared with conventional open surgery, laparoscopic gastrectomy has potential benefits for these patients due to advantages resulting from its minimally invasive approach. Herein, we report on three patients with gastric cancer in remnant stomach who underwent laparoscopic total gastrectomy with intracorporeal esophagojejunostomy successfully. The operative time was 280, 250 and 225 minutes, the estimated blood loss was 100, 80 and 50 ml and the length of postoperative hospital stay was seven, eight and nine days respectively. Our experience has suggested that laparoscopic total gastrectomy with intracorporeal esophagojejunostomy can be a safe, feasible and promising option for patients with gastric cancer in remnant stomach.

AIM: To describe the clinical characteristics, technical procedures, and outcomes of patients undergoing laparoscopic spleen-preserving distal pancreatectomy (LSPDP) for benign and malignant pancreatic neoplasms.

METHODS: The clinical data of 38 patients who underwent LSPDP in the Sir Run Run Shaw Hospital between January 2003 and August 2013 were analyzed retrospectively. Surgical techniques for LSPDP included preservation of the splenic artery and vein (Kimura’s technique) and ligation of the splenic pedicle with preservation of the short gastric vessels (Warshaw’s technique).

RESULTS: There were no conversions to open surgery in the 38 patients. Splenic vessels were conserved during spleen-preserving pancreatectomy, except in two patients who underwent resection of the splenic vessels and preservation only of the short gastric vessels. The mean operation time was 123.2 ± 52.4 min, the mean intraoperative blood loss was 78.2 ± 39.5 mL, and the mean postoperative hospital stay was 7.6 ± 2.9 d. The overall rate of postoperative complications was 18.4% (7/38), and the rate of clinical pancreatic fistula was 13.2% (5/38). All postoperative complications were treated conservatively. The postoperative pathological diagnoses were 22 cases of benign pancreatic disease and 16 cases of borderline or low-grade malignant lesions. During a median follow-up of 38 mo (range: 5-133 mo), no recurrence was observed.

CONCLUSION: LSPDP is a safe, feasible and effective procedure for the treatment of benign and low-grade malignant tumors of the distal pancreas.

Laparoscopic distal gastrectomy (LDG) for gastric cancer has gradually gained popularity. However, the long-term oncological outcomes of LDG have rarely been reported. This study aimed to investigate the survival outcomes of LDG, and evaluate the early surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) and totally laparoscopic distal gastrectomy (TLDG).

Clinical outcomes of 240 consecutive patients with gastric cancer who underwent LDG at our institution between October 2004 and April 2013 were analyzed. Early surgical outcomes of LADG and TLDG were compared and operative experiences were evaluated.

Of the 240 patients, 93 underwent LADG and 147 underwent TLDG. There were 109 T1, 36 T2, 31 T3, and 64 T4a lesions. The median follow-up period was 31.5 months (range: 4–106 months). Tumor recurrence was observed in 40 patients and peritoneal recurrence was observed most commonly. The 5-year disease-free survival (DFS) and overall survival (OS) rates according to tumor stage were 90.3% and 93.1% in stage I, 72.7% and 67.6% in stage II, and 34.8% and 41.5% in stage III, respectively. No significant differences in early surgical outcomes were noted such as operation time, blood loss and postoperative recovery between LADG and TLDG (P >0.05).

LDG for gastric cancer had acceptable long-term oncologic outcomes. The early surgical outcomes of the two commonly used LDG methods were similar.
