Multiple Ileal True Diverticula with Perforative Peritonitis Required Emergency Surgery—A Case Report—

Abstract

A 54-year-old male patient receiving high-dose steroid therapy for IgA vasculitis presented with right lower abdominal pain. An abdominal CT scan showed free air and abdominal ascites. Intestinal perforation was diagnosed, and he underwent an emergency operation. During surgery, however, multiple diverticula were found in the terminal ileum, one of which was perforated. Ileocecal resection and ileostomy were performed. The histopathological diagnosis was perforated true diverticulum involving muscularis propria and adventitia. Perforation of ileal diverticula is rare and difficult to diagnose. Patients in whom this condition is suspected should undergo an emergency operation at an early stage. We herein report a case of multiple true diverticula of the small intestine with perforative peritonitis which required emergency operation.
