Perforated diverticulitis sigmoidei after laparoscopic cholecystectomy.

We present a case of 47-year-old healthy man who underwent an uneventful elective laparoscopic cholecystectomy. Despite the postoperative analgesia with non-steroidal anti-inflammatory drugs (NSAIDs), the patient developed diffuse abdominal pain culminating on the second postoperative day when the patient also had rebound tenderness. A diagnostic laparoscopy showed diverticular perforation, which was treated with laparoscopic lavage and drain. The patient's condition continued to deteriorate and the drain output resembled faecal material necessitating an emergency sigmoidium resection. The histopathological examination confirmed inflammation and perforation in the diverticulosis-bearing segment. The use of NSAID can be a reason for perforation, and may be for diverticulitis. NSAID should be used with caution in patients with a previous history or endoscopic-verified diverticulosis.
