Simple closure of a perforated duodenal diverticulum: "a case report".

Spontaneous perforation of a duodenal diverticulum is a rare but serious complication with significant mortality rates. Just over 100 cases have been reported in the world literature. One case of perforated duodenal diverticulum treated by simple closure is reported. An elderly female was admitted to our hospital with an acute abdomen. Computed tomography of the abdomen showed retroperitoneal air around the duodenum and right kidney. Laparotomy with a Kocher maneuver disclosed a perforated diverticulum in the second portion of the duodenum. Although diverticulectomy is the most common treatment, simple closure of the perforated duodenal diverticulum with drainage was performed to avoid injury to the distal common bile duct and ampulla of Vater, which were close to the diverticulum. The patient has fully recovered and has been asymptomatic with no signs of recurrence for 25 months.
