Introduction: The duodenum is the second seat of onset of diverticula after the colon. Duodenal diverticulosis is usually asymptomatic, but duodenal perforation with abscess may occur.
Case presentation: Woman, 83 years old, emergency hospitalised for generalized abdominal pain. On the abdominal tomography in the third portion of the duodenum a herniation and a concomitant full-thickness breach of the visceral wall was detected. The patient underwent emergency surgery. A surgical toilette of abscess was performed passing through the perforated diverticula and the Petzer's tube drainage was placed in the duodenal lumen; the duodenostomic Petzer was endoscopically removed 4 months after the surgery.
Discussion: A review of medical literature was performed and our treatment has never been described.
Conclusion: For the treatment of perforated duodenal diverticula a sequential two-stage non resective approach is safe and feasible in selected cases.
