Abstract
Duodenal fenestrated membranes are traditionally treated by side-to-side diamond-shaped duodenoduodenostomy, or duodenotomy and resection. We describe an alternative endoscopic approach for its resolution. A flexible panendoscopy reaching the duodenal membrane was performed. A balloon was inserted to dilate its orifice. Traction was applied to the balloon to differentiate the border of the membrane forming the duodenal wall. After visualizing the ampulla, the membrane was incised using a sphincterotome or needle knife on two sites opposite to the bile duct. From May 2001 to August 2007, ten patients with a fenestrated duodenal membrane underwent transluminal endoscopic electrosurgical incision (TEEI). Mean patient age was 3.4 years (range 1 month to 15 years). The endoscopic procedure lasted from 30 to 60 min. Oral intake began 24 h postsurgery in eight patients and at 48 h postsurgery in two patients. Hospital stay lasted for 2–5 days. After 1 year of follow-up, eight patients were asymptomatic and thriving at present, and one had a double membrane, required a second endoscopy with TEEI, and has experienced occasional vomiting. An additional asymptomatic patient was lost after 3 months of follow-up. TEEI of fenestrated duodenal membranes is a feasible and effective procedure in children.
