Endoscopic internal drainage using transmural double-pigtail stents in leaks following upper gastrointestinal tract...

different endoscopic procedures have been proposed for the management of surgical leaks. Endoscopic internal drainage using trans-fistulary double-pigtail plastic stents has emerged as an alternative strategy, especially in fistulae presenting after laparoscopic gastric sleeve.

a retrospective case series was performed at a single tertiary care center including all upper gastrointestinal post-surgical leaks primarily managed with endoscopic trans-fistulary insertion of double-pigtail plastic stents. Clinical success was defined as the absence of extravasation of oral radiographic contrast and radiological resolution of the collection with adequate oral intake Results: nine patients were included, six (66.6 %) females with a median age of 52.6 years (IQR 47-60). Five cases presented after laparoscopic gastric sleeve, two cases after distal esophagectomies, one after a Roux-en-Y gastric bypass and another one after a pancreaticoduodenectomy. Fistulae measured < 10 mm in five patients (55.6 %) and 10-20 mm in four patients (44.4 %). Six were early leaks. Technical and clinical success was achieved in nine (100 %) and seven (77.8 %) cases, respectively. Seven (77.8 %) patients required ≤ 3 endoscopic procedures. The median hospital stay after the first endoscopic procedure was 12 days (IQR 6.5-17.5 days), while the overall median time until leak healing was 118.5 days (IQR 84.5-170). One patient with a post-esophagectomy intrathoracic leak developed an esophageal-tracheal fistula 37 days after stent deployment.

our results support the use of endoscopic internal drainage in postsurgical abdominal leaks, regardless of the type of surgery. Although only two patients with intrathoracic dehiscence were included.
