Perforated jejunal diverticulitis: a rare but important differential in the acute abdomen

Abstract

Abstract Background Diverticulosis of the small bowel is rare and, in most cases, discovered incidentally. However, diverticulitis and other complications are important to consider in the differential of an acute abdomen, especially in the elderly population. Case presentation The patient was a 59-year-old female who presented with acute lower abdominal pain progressing to peritonitis. Computed tomography scan showed a large inflamed and perforated diverticulum on the mesenteric side of the jejunum. Exploratory laparotomy revealed a dilated proximal jejunum with a 5-cm inflamed and perforated mesenteric diverticulum. A small bowel resection with primary anastomosis was performed. Conclusions Jejunal diverticulitis remains a diagnostic challenge. Although uncommon, owing to its high mortality rate, it is an important clinical entity to consider and requires timely management.
