Abstract
We report a case of peritonitis due to jejunal diverticular perforation. An 82-year-old man visited our hospital because of pain in the left upper abdomen. He had a past history of colorectal diverticula. The laboratory data showed a high level of C-reactive protein (CRP). The computed tomography (CT) scan revealed free air and elevation of the fat density surrounding the small intestine. These findings led to a diagnosis of perforative peritonitis. An emergency operation was therefore performed. At laparotomy, multiple diverticula of the jejunum were recognized at a segment of 20∼60 cm on the distal side from the Treitz's ligament, and one of them showed a punched-out perforation. These were located on the side of attachment to the mesentery. Wedge resection of the jejunum, including the perforated diverticulum, was performed. This lesion was diagnosed as pseudo-diverticulum of the jejunum by the clinical features and the histopathological findings.
