Intussusception is the invagination of a segment of the bowel into an adjacent segment. It is the most common cause of intestinal obstruction in children, but in adults, it is rare, accounting for 1% of all intestinal obstructions and 5% of all intussusceptions, with malignancy being the most common cause. In the past, it was typically diagnosed intraoperatively. However, with the availability of computed tomography for abdominal imaging, recognizing the condition's signs has become crucial. Surgical intervention is essential for managing neoplastic cases and their complications.

A 45-year-old female presented with severe abdominal pain encompassing her entire abdomen, abdominal distension, vomiting, and persistent constipation. Over the past two months, she has also experienced considerable weight loss. After an initial history review, examination, and imaging investigations, the patient was diagnosed with ileo cecal intussusception resulting from a colo rectal mass located in the cecum and ascending colon. This condition was surgically managed through an extended right hemi colectomy.

Intussusception is uncommon in adults, but it should be considered in patients with intestinal obstruction. Surgical intervention is essential.

Intussusception is a surgical emergency in which a part of the intestine slides into the distal adjacent part. Adult colocolic intussusception secondary to a tumoral process is a rare but serious clinical condition requiring immediate surgical intervention.

We report a case of a 65-year-old male patient presenting with abdominal pain and distention, subsequently diagnosed with colocolic intussusception in the descending colon with closed-loop bowel obstruction with impending caecal perforation. An exophytic mass on the descending colon was discovered intra-operatively, prompting a subtotal colectomy with ileosigmoidal anastomosis and loop ileostomy with the suspicion of malignancy. The histopathological examination of the surgical specimen concluded a moderately-differentiated colonic adenocarcinoma with 40% mucinous component.

Adult intestinal intussusception is a rare but serious condition differing greatly in etiology from its pediatric counterpart. Its preoperative diagnosis is challenging in adults, which appears to be due to its imprecise presenting signs and symptoms; thus, the condition can be mistaken for other causes of intestinal obstruction. Adenocarcinomas remain the most common cause of malignant tumors in the colon, which also makes them one of the causes for colocolic intussusception.

Intussusception can appear as a surgical emergency even in the elderly, necessitating prompt surgical intervention to avoid intestinal ischemia and gangrene. Its diagnosis can be aided to a great degree by CT imaging.

Colocolic intussusception is a rare surgical emergency in adults and is often associated with neoplastic lead points.

We present a case of intussusception of a gastric remnant in a patient years after undergoing a Billroth II procedure that was treated with esophagogastroduodenoscopy. Although rare in adults, intussusception has been documented with increasing frequency in adult patients who have undergone Billroth II, mini-gastric bypass, and Roux-en-Y gastric bypass surgery. Timely management can decrease damage due to ischemia.

Abdominal pain is a common chief complaint seen in the emergency department (ED), both in adult and pediatric populations. In pediatric emergency medicine, one diagnosis that is often considered is intussusception; in adult emergency medicine, this is typically less common. The classic teaching in adults is that the most common cause of intussusception is malignancy. In the following case report, however, the etiology of intussusception was not from malignancy but rather idiopathic. This case report describes an elderly female presenting to the ED for abdominal pain, nausea, vomiting, and hematochezia. She underwent abdominal imaging with findings concerning for intussusception; this necessitated urgent operative intervention. She was found to have ileocolonic intussusception. Tissue biopsy was sent for analysis to evaluate for malignancy. This was negative. While emergency physicians often keep intussusception high on their list of differential diagnoses when dealing with pediatric patients with abdominal pain, it is rarely considered in the adult population. Abdominal pain is one of the most common chief complaints seen in emergency medicine. Intussusception should definitely be considered as this could be the etiology of abdominal pain and, in rare circumstances, the potential etiology for an acute abdomen.

Gastric cancer is the most prevalent tumor in Chinese men, and surgery is currently the most important treatment. Billroth II and Roux-en-Y are the anastomosis methods used for reconstruction after gastrectomy. Jejunal intussusception is a rare complication after gastric surgery.

Intussusception after gastric surgery occurs mostly at the gastrojejunostomy site for Billroth II reconstruction, and the Y-anastomosis site for Roux-en-Y reconstruction. Many studies have reported that postoperative intussusception appears at the anastomosis after bariatric surgery, while a few have reported intussusception at the anastomosis and its distal end after radical gastrectomy.

A review was carried out to analyze intussusception after radical gastrectomy with roux-en-y anastomosis during the current situation. And the relevant mechanisms, diagnosis, treatment methods, etc. are described, hoping to provide better guidance for clinicians

Retrograde intussusception (RI), although relatively uncommon, has been increasingly seen in adults post Roux-en-Y gastric bypass (RYGB) surgery. The exact mechanism for its occurrence remains unknown but several theories have attributed it to bowel persialtic dysmotility. The increase in bariatric surgery over the last decade has resulted in a proportionate increase in the number of cases of intussusception seen globally. We report a case of RI seven years following RYGB done for morbid obesity.

Intussusception is more commonly considered in the pediatric patient with abdominal pain, but can occur in adults as well. Adult patients are more likely to have an underlying intra-abdominal pathology leading to the condition. We present an adult patient presenting with abdominal pain with ileocecal intussusception diagnosed on imaging and confirmed surgically. In this case, appendiceal pathology served as the lead point for the intussusception.

Brunner's gland hamartoma is a rare benign duodenal tumor. It occurs in Brunner's glands, which are found in the duodenum and produce secretions that protect the duodenum from pancreatic enzymes, gastric acid, and other agents. Endoscopic or surgical resection is required for these hamartomas. Duodenal intussusception is a relatively rare condition, usually caused by the presence of benign tumors, such as fibroadenomas, lipomas, papillomas, or sometimes with malignant neoplasms.

We report a case of giant Brunner's gland hamartoma in the duodenum causing antiperistaltic intussusception in a 45-year-old female patient. The patient reported a 3-year history of chronic anemia, and this mass was detected incidentally by computed tomography (CT) during investigations for chronic anemia and weight loss. Pre-operative abdominal and pelvis contrast revealed a sausage-shaped intraluminal structure with alternating fat planes and vessels distended in the third part of the duodenum up to the first part of the duodenum. Pancreas-sparing duodenectomy was performed. The patient recovered very slowly and was discharged on postoperative day 15 in good condition. Histology showed a large polypoid mass measuring 12.0 × 7.5 × 2.0 cm³, consistent with Brunner's gland hamartoma.

Brunner's gland hamartoma can present with features of duodenal intussusception or ampullary obstruction but is rarely seen to cause retrograde jejuno-duodenal intussusception. Pancreas-sparing duodenectomy is the best surgical option in adult patients with intestinal intussusception associated with giant lesions close to the ampulla of Vater, especially in the presence of features of malignancy.

Intestinal duplication, a congenital malformation, is considered a rare condition, particularly in adults. Although it affects young children, a minority of patients remains asymptomatic until adulthood. Here, we describe a case of an intestinal duplication cyst that caused intussusception by a unique mechanism.

A 19-year-old man was admitted to our hospital for intermittent abdominal pain. Computed tomography revealed colonic intussusception induced by a nodular mass in the ileocecal region. Urgent ileocecal resection was performed because of the risk of colonic ischemia. The resected material comprised a stool-filled noncommunicating cyst that protruded into the enteric lumen at the ileocecal valve. Histological analyses revealed that the inner wall of the cyst was lined with colonic mucosa and that the muscle layer of the cyst was shared with that of the original enteric wall; furthermore, the cyst had a vestige of an opening site in the wall. We concluded that the cyst was an intestinal duplication that poured stool into its lumen through the tiny orifice, thereby triggering intussusception.

The present case suggests that stool-pouring can cause intussusception into the space of an intestinal duplication lesion.

Intussusception of the gastrointestinal viscera is rarely encountered in adult patients and is frequently associated with a polypoidal lead point, which is often malignant. We would like to present the case of a 68-year-old male with a history of decompensated liver disease and multiple medical comorbidities, who was discovered to have an incidental gastrogastric intussusception on CT. No polypoidal lead point was seen and we believe this to be the first case of its kind to be described. We suggest that distortions in the patient’s visceral and vascular anatomy and raised intra-abdominal pressure resulting from concomitant ascites, hiatus hernia, portal hypertension and oesophageal varices have provided an alternative mechanism for a gastrogastric intussusception to develop.

The purpose of this study was to present data on the diagnosis, treatment, clinical course, and outcome of cases of intestinal invagination.

Data of 11 patients treated for intestinal invagination at one center between June 2009 and July 2015 were analyzed retrospectively in terms of demographic data, etiological factors, anatomical localization of invagination, admission complaints, physical examination findings, diagnostic imaging modalities used, postoperative complications, and hospital stay.

Of the total, 9 (81.8%) patients were female and 2 (18.2%) were male. Nine (81.8%) cases occurred due to benign causes and 2 to malignant causes. One (9%) patient had jejunojejunal invagination, 5 (45.5%) had ileoileal invagination, and 5 (45.5%) had ileocecal invagination. Right hemicolectomy-ileotransversostomy was performed in 5 (45.5%) patients and segmental small bowel resection with end-to-end anastomosis in 6 (54.5%).

Intestinal invagination is a rare cause of acute abdomen in adults that may have a variety of etiologies and therefore may present with different clinical pictures. Abdominal pain, nausea, and vomiting are the most common symptoms. The rate of accurate diagnosis is 30% to 35% using ultrasonography and 50% to 80% using computerized tomography. In adults, the preferred treatment is surgery. As malignant pathologies are responsible for some cases of invagination, oncological principles should be strictly observed in surgical treatment. Though a rare cause of acute abdomen and/or ileus in adults, invagination is a clinical condition that must be kept in mind in the differential diagnosis.

Intussusception is rare cause of chronic abdominal pain in adults.

Intussusception in adult is rarely caused by idiopathic conditions. Main causes are inflammatory diseases, benign or malignant tumors and motility disorders. As a benign cause, lipomas appear as a particularly rare gastrointestinal intraluminal tumor occurring with highest incidence in the colon, mostly in the caecum and ascending colon.

A 57-year-old male patient was admitted at the surgical emergency in Belo Horizonte, with history of chronic and intermittent diffuse abdominal pain, associated with variations of his bowel habits and rare episodes of vomiting starting around 3 days prior to admission.

Intussusception is the cause of adult symptomatic bowel obstruction in 1% of the cases and its colocolonic occurrence represents 17% of all intestinal intussusceptions in adults. The reported case presents itself as even rarer considering its evaluation according to the epidemiological statistics of 1:5 men/women ratio and lipoma’s most common location being the right colon. Intussusception and intestinal obstructions caused by intraluminal lipomas are not often described in the literature and its occurrence is directly related to its size, usually larger than 2 cm diameter. The management of lipomatous intraluminal lesions of the colon is traditionally surgical, and it allows a selective resection, depending on the size of the tumor, length of intussusception, and the amount of inflammation.

Patients with chronic abdominal symptoms and semi-obstruction caused by intussusception are rarely diagnosed before surgery unless there is a high index of suspicion. Colonoscopy contributes to diagnosis given that it provides direct visualization and biopsy.
