Management of Duodeno-Jejunal Flexure Transection after Blunt Trauma - A Modified Approach

Background: Small bowel injuries are infrequent after blunt trauma and typically affect fixed segment. Untimely management of such injuries, results in high-output entero-cutaneous fistula which increases morbidity and mortality. Treatment of duodeno-jejunal flexure transection has been traditionally done by pyloric exclusion with gastrojejunostomy, but more recent evidence suggests that end-to-end anastomosis or primary closure may be equally effective in which duodeno-jejunal anastomosis is protected via an external tube duodenostomy. Objective: The objective of the study is to provide a modification to the technique of management of duodeno-jejunal flexure injury, avoiding external tube duodenostomy. Material and Methods: Patients admitted from July 1, 2015 to June 1, 2018 were identified and examined for duodeno-jejunal flexure transection. Non-accidental injury cases were excluded. Results: In the study period, a total of 10 patients were admitted with duodeno-jejunal flexure transection. All cases were admitted 24 hours after the injury and presented with shock. After fluid resuscitation and investigations, they were taken for urgent laparotomy. The whole of duodenum was mobilised, the transected ends were debrided and end-to-end duodenojejunal anastomosis was performed in two-layer fashion. An 18-French Nasojejunal (NJ) tube was placed beyond the anastomosis, and an 18-French nasogastric (NG) tube was placed in the stomach for gastric decompression. A feeding jejunostomy was performed in all cases. Both NG and NJ tubes were removed after bowel movements started and FJ was removed on first follow up. There was no incidence of duodenum related complications, and all were doing well on follow up. Discussion and conclusion: Placing the nasojejunal and nasogastric tube eliminates the need for duodenostomy and gastrostomy, respectively. This method protects the duodeno-jejunal anastomosis and decreases the incidence of duodenum-related complications.
