Intussusception in healthy adults is rare and often associated with oncologic diseases. This case report presents a case of an ileo-colic intussusception reaching down to the descending colon in a healthy adult that required ileo-colic resection.

We present a case of a 78-year-old male patient with acute onset unspecific abdominal pain. The medical history was unremarkable. Preoperative radiologic assessments showed an invagination of the small intestine into the colon without any signs of polyps or tumours. An emergency laparotomy with resection of the affected intestine was performed. The pathologist described a 49 cm length of intussuscepted colon and an additional 7 cm intussusception of the terminal ileum. A circular area with multiple polyps extending over 8 cm in the colon could be identified. The microscopic findings showed a low-grade dysplasia within this area. Following surgery, the patient was discharged to rehabilitation after a ten-day hospitalization.

Intussusception in adults is rare and the clinical presentation includes unspecific symptoms making the diagnosis challenging. In 90% of the cases, a pathologic lesion is found (two-thirds are neoplasms). An intussusception involving the colon should be treated surgically without prior reduction due to the high incidence of a neoplasm and the risk for perforation and tumour dissemination.

In the literature, neoplastic disease represents the major cause for intussusception in adults. This report presents a rare case of an ileo-colic intussusception reaching down to the descending colon treated successfully with a subtotal colectomy.

Intussusception is a differential diagnosis in adults with abdominal pain.

Unlike in infancy, where intussusception is an abdominal emergency, diagnosis of intussusception could be tricky in adults as most of these patients present sub-acutely with vague abdominal symptoms. Early diagnosis could impact these patients significantly in decreasing morbidity and mortality along with reduction in healthcare expenses. Colo-colonic intussusception is rare and accounts for less than 20% of adult intussusception. More than 50% of adult intussusception is caused by mass-like lesions. In such cases, this could be an early presentation of malignant intestinal lesions. Abdominal CT is mandatory in all adult patients; when combined with ultrasound, it has 95.5% accuracy of pre-operative diagnosis. Here we report a case of a 42-year-old female who presented with a two-month history of intermittent abdominal pain; a CT abdomen revealed colo-colonic intussusception which was initially missed on prior imaging. We discuss the importance of considering intussusception as a rare differential of abdominal pain, the need for early diagnosis, and the role of colonoscopy and non-surgical management in adults.

Intestinal intussusception caused by intestinal duplication and ectopic pancreas is extremely rare in the clinic and has not been reported previously.

A 29-year-old man was admitted to the hospital for chronic abdominal pain and bloating. The preoperative diagnosis was intestinal obstruction and intussusception. Then, laparotomy, partial small intestinal resection and extraintestinal decompression were performed. Postoperative pathology confirmed intestinal duplication and ectopic pancreas. After surgery, the patient recovered well with no complications. No recurrence was observed after more than 5 mo of follow-up.

We report a new case of a young male with intussusception caused by intestinal duplication and ectopic pancreas. Surgery is the main treatment for these conditions. This study aimed to raise awareness and provide information to improve the clinical management of this rare yet serious condition.

A colon lipoma is defined as a benign tumor made of adipose tissue present in the submucosa. Lipomas of the colon are unusual with a frequency of 0.035%-4.4%. We present an uncommon case of a 41-year-old female with left colonic lipoma causing intussusception. The patient presented with abdominal pain at the left iliac fossa. She underwent an emergency exploratory laparotomy plus left hemicolectomy and was followed in the surgical out-patient clinic postoperatively. She was found doing well taking a normal diet and having normal bowel habits. The overall prognosis depends on the complete removal of the tumor.

Intussusception in adults is a challenging diagnosis that often requires a high degree of suspicion. In adults presenting with symptoms, almost 90% have underlying neoplasms. Most frequently, the presentation will include nonspecific abdominal pain, vomiting, and mucoid hematochezia. In this case, we present a 39-year-old female with a rare presentation of chronic, recurrent right upper quadrant abdominal pain over a 5-month interval. The misleading presentation with which the patient presented led to a delay in diagnosis and treatment of colon malignancy and serves to advocate for intussusception as a differential for adult patients presenting with obstructive symptoms of unknown origin and recurrent abdominal pain. Such cases should persuade physicians to plan prompt surgical intervention as to not delay optimal diagnostic and therapeutic outcomes.

The differentiation of surgical from nonsurgical adult intussusception may enable the appropriate selection of management strategies.

This study aimed to investigate the diagnostic potential of multidetector computed tomography (MCDT) features to differentiate surgical from nonsurgical adult intussusception and develop a diagnostic model.

A retrospective study was performed on 96 patients with intussusceptions at the University Medical Center Hospital between January 2014 and January 2020. Two radiologists reviewed all images, and intussusception characteristics were documented. The location of intussusception, length, diameter, interposed fat thickness, lead point, and complications were evaluated. Based on the results, a diagnostic tree model was developed to differentiate between surgical and nonsurgical adult intussusception.

A total of 99 intussusceptions in 96 patients (mean age: 53.0 ± 16.5 years), including 35 (35.3%) enteroenteric, 27 (27.3%) enterocolic, and 37 (37.4%) colocolic lesions, were evaluated. Of the enteroenteric intussusceptions, 22 (62.9%) were surgical, including 19 (79.2%) with lead points. Among colon intussusceptions, 63 (98.4%) were surgical, and 100% had lead points. The characteristics used to predict surgical intussusceptions included lead point presence, length ≥ 5.0 cm, diameter ≥ 3.2 cm, interposed fat thickness ≥ 0.5 cm, and complications (p < 0.001). Based on these features, we established a diagnostic tree model that correctly classified 96 (97%) of 99 lesions.

Our study reinforces the importance of MDCT for the diagnosis and guided management of adult intussusceptions. The characteristics that predicted surgical intussusceptions included lead points, length, diameter, interposed fat thickness, and complications. A systematic approach using this diagnostic tree model could be used to distinguish surgical and nonsurgical adult intussusception.

Adult intussusception is recognized as an abdominal emergency. More than 90% of adult patients with intussusception have distinct causes that are related to benign or malignant tumors. In contrast, idiopathic intussusceptions, which are observed in children, are rare conditions in adult. Especially, colo-colonic idiopathic intussusceptions are rare among them. Surgery is traditionally considered the primary treatment option. Recently, laparoscopic surgery has been reported to be safe and feasible. However, laparoscopic surgical reduction, which is a common procedure in pediatric surgery, is not common in adult intussusception.

We report a 34-year-old man who presented with sudden abdominal pain. Computed tomography revealed the target sign in the transverse colon. There was no evidence of bowel obstruction, bowel wall edema, or tumor. We diagnosed idiopathic intussusception and selected laparoscopic procedure because of the strong abdominal pain experienced by the patient. There were no signs of perforation, bowel wall ischemia, or tumor in abdominal cavity. We confirmed idiopathic colo-colonic anterograde intussusception. Laparoscopic surgical reduction was achieved by a combination of delicate direct pressure on the anal side of the transverse colon and gentle pulling on the oral side. The patient’s postoperative course was uneventful.

We achieved successful surgical reduction laparoscopically because of an accurate preoperative diagnosis based on characteristic computed tomography features and appropriate surgical technique. Laparoscopic procedure and surgical reduction is considered to be an effective treatment strategy for adult idiopathic intussusceptions with severe symptoms.

Adult intussusception is less common than paediatric intussusception. The aim of this study was to explore the clinical presentation, aetiology, diagnosis and treatment of adult intussusception.

Adults (>18 years) with intussusception treated by surgical or conservative measures were included from January 2005 to January 2018, and the manifestation, types, diagnosis and treatment of adult intussusception in our centre were reviewed.

A total of 150 patients with adult intussusception were included in this study. The clinical manifestations included 111 cases (74%) of abdominal pain, 38 cases (25.3%) of bloody stool, 37 cases (24.7%) of bowel obstructions, 33 cases (22%) of abdominal distension, 29 cases (19.3%) of nausea and vomiting, 19 cases (12.7%) of an abdominal mass, and 12 cases (8.0%) of diarrhoea. The types of intussusception were classified into 36 cases (24%) of enteric intussusception, 87 cases (58%) of intestine-colon intussusception and 27 cases (18%) of colonic intussusception. Surgical intervention was applied in 139 cases (92.7%), including 115 patients who underwent open surgery, and laparoscopy-assisted surgery was performed in 24 patients. The main pathogenesis of intussusception was malignant tumors in 51 cases (36.7%) and benign tumors and polyps in 49 cases (35.3%).

Malignant and benign tumors are the main causes of adult intussusception. Abdominal CT is the preferred evaluation method for the preoperative diagnosis of this condition. The choice of surgical procedure depends on the location and type of intussusception.

Proximal small bowel intussusception occurring in an adolescent Crohn's disease patient is an extremely rare entity. It is usually primary without a lead point and quite often a transient phenomenon. We report such transient and intermittent jejunal intussusception in a 16-year-old male, developing immediately in a postoperative period after a stoma reversal for jejunal stricture perforation peritonitis.

Intussusception is a rare cause of postoperative small bowel obstruction in adult and the treatment is still debated.

Postoperative intussusception is a rare cause of intestinal obstruction in adults. Intussusception refers to a condition in which a segment of the intestine invaginates into the lumen of an adjacent segment of the intestine.

We report a case of postoperative jejunojejunal intussusception in a 42-year-old male following a laparoscopic low anterior resection for rectal cancer. In post-operative day (POD) 2 the patient showed intermittent bowel obstruction and fever. Diagnosis was established with abdominal computed tomography (CT) and enteroclysis, which led to a spontaneous reduction of the invagination.

The incidence of intussusception in adults is rare condition. It represents less than 5% of all cases. In adults, transient asymptomatic enteric intussusception often resolves spontaneously without any treatment. When bowel obstruction is complete and persistent, surgery is need. Intussusception as cause of intestinal obstruction should be kept in mind in a post operative patient who develops obstructive symptoms. Early diagnosis makes the difference between surgical and others treatment. The pathogenesis and diagnosis of postoperative intussusception in the adult is discussed in the case report.

The authors presented a rare cause of postoperative small bowel obstruction treated without surgery. The peculiarity of this case report is that the authors have successfully used, in an adult, conservative treatment with gastrografin, which is the treatment of choice used in children. The use of gastrografin was decisive and there were no recurrences in the follow up.

Rectal prolapse is usually of benign etiology. Rarely, sigmoido-rectal intussusception results from a malignant lead-point. We report the case of a patient with a partially obstructing sigmoid cancer causing a full thickness rectal prolapse requiring surgical intervention. An 82-year-old woman presented with 1 week of rectal bleeding, fecal incontinence, and weight loss. Computed tomography identified sigmoido-rectal intussusception. Colonoscopic biopsy revealed high-grade dysplasia. Magnetic resonance imaging demonstrated a 6-cm mass forming the lead point of the intussusceptum with epiploic appendages seen within the rectal lumen. She underwent laparoscopic low anterior resection with final pathology consistent with T2N0 adenocarcinoma, and recovered well. Among adult patients with rectal prolapse, suspicion for underlying malignancy should prompt a thorough investigation to inform the decision for resection, which may be safely performed by minimally invasive techniques.

Intussusception, a process whereby a segment of the intestine telescopes into the adjoining intestinal lumen, is a rare source of pain in adults that present with nonspecific abdominal pain. Imaging is the mainstay for diagnosis, which requires prompt and accurate interpretation to prevent complications. The following report details the misdiagnosis of intussusception in a 54-year-old male, whom presented to the emergency department with a 4-day history of nonrelenting abdominal pain, nausea, vomiting, and constipation. Following blood tests, chest, and abdominal imaging, the patient was discharged with a suspected passed renal stone. He soon represented to the General Practitioner, however, with equivalent pain; prompting a review of the images. It was apparent that the initial radiologist failed to recognize the subtle presence of intussusception. This case highlights the necessary consideration of intussusception as a differential diagnosis in adult patients presenting with intermittent abdominal pain. The case further emphasizes that radiologists should be familiar with the subtler signs of intussusception.

Intestinal intussusception in adults is rare, accounting for approximately 1% of all bowel obstructions.

Intussusception is a relatively common condition seen in children. In comparison, adult intussusception is rare and is often secondary to inflammatory diseases, benign or malignant tumors and motility disorders. Being a benign cause, lipomas appear as a particularly rare gastrointestinal tumor.

We present a case of colo-colonic intussusception secondary to a sigmoidal lipoma, in a 40-year-old man. We describe the different aspects of diagnosis and management of this rare complication.

Adult intussusception is the cause of symptomatic bowel obstruction in 1% of cases and its colo-colonic occurrence represents 17% of all intestinal intussusceptions. The case that we describe is particularly unique because apart from being an example of intussusception in adults, it occurred in the sigmoid colon and was not associated with a malignant lesion. The treatment of intussusception in adults is surgical resection because of the high incidence of underlying malignancy. Colonoscopy is a modality which allows direct visualization of the lipoma. However, intraluminal reduction via colonoscopy is not recommended.

Colo-colonic intussusception is a very rare complication of lipoma. It is determined that the treatment is surgical due to the risk of malignancy.

Non-Hodgkin's lymphoma of B-cell type is the second most common neoplasm after Kaposi's sarcoma among patients with human immunodeficiency virus infection. Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome (AIDS) involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of multiple jejunal intussusception caused by Burkitt lymphoma in a 42-year-old AIDS patient. Upper gastrointestinal endoscopy and surgical biopsy were performed and a complete diagnostic study including histological and immunohistochemical analyses showed Burkitt lymphoma.
