Peritonitis due to perforation of primary congenital duodenal diverticulum - a case report and review of the literature

Background: Duodenal diverticulum is a relatively common finding that can be incidentally found in upper gastrointestinal endoscopy in up to 20% of cases. Most duodenal diverticula are asymptomatic, and perforation of a duodenal diverticulum is extremely rare. Case report: We present a case of spontaneous rupture of a duodenal diverticulum in a 41-year-old female diagnosed with perforated duodenal diverticulum intraoperatively. Resection of the perforated diverticulum was performed, and closure was done interruptedly in two layers. The patient recovered uneventfully. Conclusion: Duodenal diverticulum perforation is a rare condition in which accurate preoperative diagnosis and treatment are challenging. Operative treatment with diverticulectomy and one or two-layer closure is the treatment of choice in most cases.
