Successful closure of a duodenal stump leak with an over-the-scope clip using double-balloon endoscope
A 62-year-old man with a history of distal gastrectomy and Billroth I reconstruction for gastric cancer was diagnosed with early gastric cancer in the remnant stomach, necessitating endoscopic submucosal dissection. On postoperative day 1, the patient experienced sudden-onset abdominal pain. Computed tomography (CT) demonstrated free air and mediastinitis, indicating a delayed perforation. Total gastrectomy with Roux-en-Y reconstruction, irrigation, and drainage was subsequently performed.
On postoperative day 5, bloody discharge was observed coming from the drain. On postoperative day 6, double-balloon endoscopy revealed two duodenal stump leaks measuring approximately 4 mm and 3 mm, respectively, with brisk bleeding in one of them ([Fig. 1], [Fig. 2]). Repeat CT identified the gastroduodenal artery as the source of bleeding ([Fig. 3]), and arteriogram coil embolization successfully achieved hemostasis. Considering that fistulas could cause intra-abdominal rebleeding or intra-abdominal abscesses, closure using over-the-scope (OTS) clips was planned. However, the diameter of the double-balloon endoscope tip was smaller than that of compatible OTS clips, complicating the mounting process. To address this, vinyl tape was wrapped around the scope tip several times to increase its outer diameter, enabling OTS clip mounting onto the scope ([Fig. 4], [Video 1]). This facilitated successful fistula closure using OTS clips ([Fig. 5]), significantly improving the patient’s condition without complications or recurrent leaks.










OTS clips are a novel endoscopic modality used to close gastrointestinal defects [1] [2]. Duodenal stump leakage is a serious post-gastrectomy complication [3], and endoscopic treatment is technically challenging in patients who have undergone Roux-en-Y reconstruction [4]. This case highlights the significant therapeutic potential of OTS clips with a double-balloon endoscope for closing fistulas, even in complex postoperative reconstructions.
