성안에서 유발펀 맥켈씨 게살 반전에 의한 장중첩증 = Intussusception in an adult secondary to an inverted Meckel’s diverticulum

다국어 초록 (Multilingual Abstract)

A Meckel's diverticulum, a true congenital diverticulum, is a small bulge in the small intestine present at birth. It is a vestigial remnant of the omphalomesenteric duct, and is the most frequent malformation of the gastrointestinal tract, occurring in 1-3% of the population according to autopsy studies. The most common presenting symptom is painless rectal bleeding, followed by intestinal obstruction, volvulus and intussusception.
Although Meckel's diverticulum is a relatively common anomaly, inverted Meckel's diverticulum has been reported rarely. Herein the author describe a case of inverted Meckel's diverticulum located at the distal ileum simulating a benign tumor. Computed tomography showed a small mass with a central area of low fat density. Surgical resection revealed a Meckel’s diverticulum containing an ectopic gastric tissue with ulceration. The unique clinical symptoms and the methods of diagnosis are discussed. Special features regarding the pathophysiology and treatment of an inverted Meckel's diverticulum acting as an intussusception are also reviewed.
