Abstract
A 63-year-old female presented with right upper quadrant pain. Computed tomography of the abdomen showed retroperitoneal gas on the dorsal aspect of the duodenum. Acute abdomen due to duodenal perforation was the most likely diagnosis and emergency laparotomy was performed. A perforated duodenal diverticulum was found in the descending portion of the duodenum. After the diverticulum was covered with the greater omentum, a tube was placed through the wall of the stomach to decompress the duodenum. Thereafter re-perforation occurred, but continuous drainage from the decompression tube of the duodenum was successful. Perforation of the duodenal diverticulum is a rare complication and we have great difficulties in diagnosis and treatment. It is important to select a reasonable surgical procedure considering possible postoperative complications.
