Abstract

Background and aim: Clinically relevant pancreatic leaks of jejunal-pancreatic anastomosis after pancreato-duodenectomy (PD) occur in 9-15% of cases. Endoscopic strategies for management of pancreatic fistula, may allow to avoid reoperation and shorten times for fistula closure, but are still understudied and not widely performed. Aim of the present paper is to describe different endoscopic techniques used to treat such conditions.

Methods: It was a retrospective, single centre, study. All patients who underwent endoscopic treatment for pancreatic leaks following PD between 1st January 2013 and 31th May 2019 at our Centre were reviewed. Depending on the morphology and severity of the leak, four main endoscopic techniques were performed: (1) trans-anastomotic intraductal pancreatic stent insertion; (2) lumen-apposing metal stent between the jejunal loop and the retroperitoneum toward the pancreatic stump insertion ("yoyo-stent"); (3) large calibre nose-to-retroperitoneum drain insertion; (4) when a wide damage of the jejunal wall or a coexistent biliary-jejunal leak were observed, triple metal stent insertion was performed as follow in order to close the defect: enteral fully-covered SEMS in the jejunal stump, a pancreatic metal stent into the Wirsung duct and a fully-covered SEMS across the bilio-digestive anastomosis, through the meshes of the enteral stent. In all cases, surgical drain was simultaneously retracted.

Results: We identified 13 patients who underwent endoscopic treatment for POPF after PD. In total, 5 patients underwent "Yoyo stent insertion", 3 with nose-to-collection drain placement and four patients were treated with triple-stent insertion; in only one patient intrapancreatic SEMS insertion was performed. Technical success was 100% and clinical success was 83.3%. Mean time for leak closure was 4.8 days (range 2-10). During the follow-up interval, no leak recurrences were observed.

Conclusions: Our experience confirms efficacy and safety of endoscopic management of POPF following pancreatoduodenectomy management. Endoscopy should play a central role in this clinical scenario.
