Pancreatic surgery remains associated with significant mortality and morbidity. Efforts are generally focused on reducing postoperative complications, but early detection of patients at risk could be another effective strategy. Cephalic duodenopancreatectomy (DPC) is the treatment of choice for pancreatic head adenocarcinomas and Vater ampullomes. In the multicenter series of the French Association of Surgery published in 2010, DPC had a hospital mortality of 4% and a morbidity of 54%, about half of which corresponded to severe complications. In Algeria, in recent years, there has been a reduction in post-DPC mortality, especially in high-volume operating centres. We report the case of a patient operated for an adenocarcinoma of the head of the pancreas, in whom a DPC was performed with a favorable initial evolution. Three weeks after his discharge, he returned for abdominal pain accompanied by an infectious syndrome. The scan showed a tubular formation of 5 cm intra-abdominal. The surgical revision confirmed the presence of an intra-abdominal drain fragment responsible for a digestive wound in the small intestine. The purpose of this article is to draw attention to this exceptional, but possible complication in order to make surgeons aware of the need for particular vigilance when managing postoperative drains.
