Mesenteric Meckel’s diverticulum or intestinal duplication cyst: A case report with review of literature

Abstract

HighlightsMesenteric Meckel’s diverticulum and intestinal duplication cyst both are congenital anomaly of the gastrointestinal tract.Preoperative diagnosis is very hard to establish even after Surgery.Ectopic gastric or pancreatic mucosa can be found in both these pathologies.Surgical treatment is gold standard of both because of their complictions.

Adult intussusception associated with mesenteric Meckel’s diverticulum and antimesenteric ileal polyp

“…In this case, no evidence of a separate blood supply was found; however, a previous case series of 776 patients found as few as 10% of MD with an identifiable distinct blood supply 19. The presence or absence of heterotopic tissue is unhelpful in distinguishing between these two congenital abnormalities since 16%–33% of IDCs have heterotopic tissue compared with 55% of MD 8. Kurzbart et al provided compelling evidence for the classification of mesenteric MD as a separate entity to IDC.…”

“…It comprises all five layers of the bowel wall, possesses its own blood supply and is invariably within 100 cm proximal to the ileocaecal valve. While classically located on the antimesenteric border of the ileum, the mesenteric variant was first described by Chaffin et al in 19415 and has since been the subject of several case reports 6–17. Some experts contend that these cases should actually be classified as IDCs.…”

“…Although the exact embryological aetiology is unknown, none of the current theories support involvement of the omphalomesenteric duct 18. Around half of IDCs occur on the mesenteric border of the ileum 8. Unlike MD, they rarely communicate with the bowel lumen and share their blood supply with the surrounding bowel.…”

Duplication cyst of the ileum presenting with severe anemia detected by double-balloon endoscopy

“…Meckel’s diverticulum is normally located on the antimesenteric aspect, while ileal duplication cysts normally appear on the mesenteric aspect. When a duplication cyst is detected, resection and anastomosis, including that of adjacent normal intestine, is required in all cases, because of the shared common bowel wall and blood supply 4 9 . All duplications should be surgically treated at the time of diagnosis owing to possible complications including bowel perforation, bleeding, obstruction, and malignant changes.…”

“…All duplications should be surgically treated at the time of diagnosis owing to possible complications including bowel perforation, bleeding, obstruction, and malignant changes. Notably, 23 % of intestinal duplication cysts in adults were affected by ileal cancer 3 4 9 10 . In contrast, Meckel’s diverticulum has a vitelline artery or a clearly independent blood supply, and most cases require cystectomy alone.…”
