Case report emphasize pearls of duodenal perforation.

Introduction: Isolated duodenal perforation secondary to trauma is a rare abdominal surgical condition, with a questionable surgical approach depending on the case.

Presentation Of Case: This is a case report of a 27-year-old male patient who presented with a free perforation in the posterior wall of the third portion of the duodenal frame and secondary retropneumoperitoneum without injuring any contiguous organ, after a medium-impact blunt abdominal trauma during a soccer game.

Discussion: A laparotomy was performed, followed by duodenorraphy with Connell-Mayo suture and Lambert suture using vascular prolene in two planes. A nasogastric tube was placed up to the jejunum, and a Jackson-Pratt drain was placed in close to the duodenum next to the sutures. During hospitalization was found a positive bacterial culture of the peritoneal fluid hence received antibiotics, without complication.

Conclusion: It is essential to make a timely diagnosis with its respective individualized surgical approach and it must be managed as an emergency surgical procedure.
