One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis

Abstract

Background: Jejunal diverticulitis is one of the rare causes of acute abdomen generally seen in the elderly. Jejunal diverticulosis was defined as the herniation of the mucosa and the submucosa from the inside of the muscular layer of the bowel wall on the mesenteric side of the intestine.

Case report: We presented the intraoperative and pathological findings of a 69-year-old male patient who had presented with complaints about abdominal pain, nausea, and vomiting and been operated upon due to subileus and peritonitis induced by large-sized jejunal diverticulitis, along with his computed tomography (CT) findings.

Conclusion: Jejunal diverticulitis is uncommon and may be a disease which might be difficult to diagnose when it develops on the basis of the large-sized diverticula resembling intestinal ansae. To the best of our knowledge, the computed tomography and intraoperative findings of a case in which partial resection is applied to the jejunum due to subileus have not been previously presented in the literature.

Keywords: CT; ileus; jejunal diverticulitis.

FIG. 1. a–c.

Contrast-enhanced computed tomography images show multiple diverticula (a) (arrows), thickening in the diverticulum walls (arrowheads), and inflammation in the mesentery at the jejunal level (b). Mild dilatation was observed in the proximal small intestinal segments (arrows). In the laparotomy, multiple diverticula (arrows) were seen on the mesenteric side in the jejunal segment (c).
