Two cases of intussusception are reported with heterotopic pancreatic tissue attached to and draining into the ileum. The first patient, a boy aged 16 months, presented with ileoileal intussusception. The diagnosis was confirmed on ultrasound scan. Laparotomy and resection were performed. A 12-mm nodule of heterotopic pancreatic tissue was identified in the ileal serosa at the apex of the intussusceptum, fully formed with acinar tissue, islets, and draining duct. The second patient, also a boy aged 16 months, presented with obstructed ileocolic intussusception in which the lead point at surgery resembled a Meckel's diverticulum. Histopathology revealed a similar 10-mm nodule of fully formed pancreatic tissue in the ileal serosal tissues, with some acinar tissue extending through the wall of the intestine alongside ductal structures. In both cases there was ectopic gastric mucosa either in the distal part of the draining duct or in the small intestine itself at the opening. Heterotopic pancreas is a rare cause of intussusception. We propose that this lesion is of vitellointestinal tract origin, conceptually similar to a Meckel's diverticulum but without a diverticulum as such. Heterotopic pancreatic tissue occurring alone is more common in the proximal small intestine, duodenum, and stomach than in the ileum, and it is often asymptomatic.

Littre Hernia

A Meckel’s diverticulum is a remnant of the vitelline duct, which leads to the formation of a true diverticulum containing all layers of the small intestine. The diverticulum can contain ectopic gastric, duodenal or pancreatic tissue and is the most common congenital anomaly of the gastrointestinal tract with estimates of prevalence ranging from 0.3% to 3%. The condition is usually clinically silent. In children the most common complication is gastrointestinal bleeding caused by ulceration due to the acid secretion by ectopic gastric mucosa.

Abstract Background Meckel’s diverticulum is the most frequent congenital anomaly of the gastrointestinal tract. It can invert or invaginate into the small intestine lumen. It is usually associated with heterotopic tissue elements. Case presentation We present a case of inverted Meckel's diverticulum, clinically and radiologically diagnosed as intestinal obstruction due to intussusceptions. The diagnosis was suspected due to target sign shown on radiological examination. Pathologically, it was inverted Meckel's diverticulum obstructing the lumen in parallel plan mimicking the telescoping appearance, with heterotopic pancreatic tissue formed of exocrine and ductal components only. Conclusions Inverted Meckel’s diverticulum may present by vague symptoms and may simulate other causes of intestinal obstruction.

Congenital diaphragmatic hernia is a common developmental anomaly encountered by paediatric surgeons. It is known to be associated with extradiaphragmatic malformations, which include cardiac, renal, genital, and chromosomal abnormalities. Herein, we report a newborn born with concurrent congenital diaphragmatic hernia, Meckel’s diverticulum, and heterotopic pancreatic tissue. This is the first case report of such a triad with description of possible mechanisms of the development.

Meckel's diverticulum is the common congenital anamoly of the gastrointentestinal tract, caused due to failure of involution of vitelline duct after seventh or eighth week of intra-uterine life. It is usually present within the last 90cm of terminal ileum.  Histologically, Meckel's diverticulum consists of all layers of small intestine. Rarely, heterotopic tissue is present derived from gastric or pancreatic tissue. In the case presented here, Meckel's diverticulum was found on the ante mesenteric border of the ileum with no peritoneal attachment during routine Anatomy cadaveric dissection. It was present 26cm proximal to the ileocecal junction, with no attachment to umbilicus. It’s blood supply was derived from the vitelline artery. Histological examination revealed the presence of 3 layers: mucosa, submucosa and muscularis propria with no heterotopic tissue.

Abstract We report a rare case of adult intussusception caused by an inverted Meckel’s diverticulum with ectopic pancreatic tissue. A 43-year-old woman was referred to our hospital with complaints of abdominal distention, intermittent abdominal pain and nausea that she experienced 3 months ago. Abdominal computed tomography scans demonstrated ileo-ileal intussusception that contained a tumor with fat density as the lead point. Laparoscopic-assisted partial resection of the small intestine was performed. The surgical specimen showed an elongated polypoid lesion invaginated into the intestinal tract indicating an inverted Meckel’s diverticulum. Pathological findings showed a true diverticulum that ran antimesentrically, with tall columnar epithelium, a mucous gland and an islet of Langerhans. The postoperative period was uneventful, and she was discharged on the ninth postoperative day.

Abstract Background Lipomas are the most common cause of intussusception in adults. To our knowledge, however, no cases of lipoma and ectopic gastric mucosa with gastritis cystica profunda (GCP) have been reported. We report a case of intussusception caused by a small intestinal lipoma with ectopic gastric mucosa containing GCP-component cells within the inverted Meckel’s diverticulum. Case presentation A female in her 40s underwent computed tomography for postoperative follow-up of left breast cancer. A tumor, suspected to be a lipoma, was found in the ileum. Since there were no symptoms, the patient underwent regular follow-up. However, gradual enlargement was observed, and surgery was recommended due to the risk of intussusception. After reduction via the Hutchinson technique, laparoscopically assisted partial resection of the small intestine was performed due to suspicion that the tumor was causing intussusception starting from the ileum. Histopathologic examinations revealed proliferation of mature adipose tissue in the subserosal layer, which was diagnosed as lipoma. Furthermore, adipose tissue was found in the stem area and accordingly, we diagnosed lipoma associated with the inverted Meckel’s diverticulum. Moreover, gastric mucosa-like crypt epithelium and proper glandular tissue were identified in the mucosal membrane at the area of onset, and signs of gastric pit dilatation over the submucosa and crypt epithelium hyperplasia were observed. Diagnosis was ectopic gastric mucosa containing GCP component tissue. Conclusions Intussusception in the small intestine complicated with lipoma and ectopic gastric mucosa with GCP within the Meckel’s diverticulum has not been reported, demonstrating the rarity of our case.
