Description

<p>A 48-year-old woman with a history of multiple admissions for acute pancreatitis over the past 15 years visited our hospital with the chief complaints of epigastric pain and abdominal bloating. The patient was diagnosed as having intestinal obstruction and acute pancreatitis based on the findings of plain X-ray and blood tests. Since intussusception was seen in the descending part of the duodenum on abdominal CT, decompression for the gastrointestinal obstruction caused by intussusception was performed, in addition to the treatment of pancreatitis. Although the intussusception resolved spontaneously with conservative therapy, a diverticulum was observed in the lumen of the descending part of the duodenum in an upper gastrointestinal series and endoscopy. The intussusception was thought to have arisen from the site of the duodenal stenosis caused by the diverticulum, and the resulting mechanical stimulation was thought to have caused pancreatitis. Surgery was performed to treat the stenosis of the duodenal lumen and to prevent relapse of the intussusception. Because the patient also had intestinal malrotation, lysis of Ladd’s bands was performed along with the appendectomy and resection of the duodenal diverticulum. The histopathological diagnosis was intraluminal duodenal diverticulum. Herein, we report a case of intraluminal duodenal diverticulum, with a review of the literature.</p>
