Abstract
Per-oral pancreatoscopy (POP) is a pancreas-preserving modality that allows for targeted pancreatic duct interventions, particularly in cases where standard techniques fail. POP specifically has an emerging role in the diagnosis, risk stratification, and disease extent determination of main duct intraductal papillary mucinous neoplasms (IPMNs). It has also been successfully used for laser ablation of IPMNs in poor surgical candidates, lithotripsy for complex stone disease, and laser stricturoplasty. As experience with POP increases beyond select referral center practices, further studies validating POP efficacy with long-term follow-up will help clarify when POP-guided intervention is most beneficial in relation to surgical intervention.

Abstract
Background and study aims Cholangiopancreatoscopy-guided laser dissection or ablation (CPL) is a novel therapeutic modality for refractory benign strictures. Our aim was to describe the safety and efficacy of CPL for pancreaticobiliary disorders. Patients and methods Patients who underwent CPL using holmium or thulium laser between February 2017 and September 2019 were included. For stricture dissection, gentle strokes of the laser fiber from a distal to proximal approach were applied until luminal patency permitted advancement of the cholangiopancreatoscope. Immediate technical success was defined as ability to traverse the stricture with the cholangiopancreatoscope after CPL. Short-term technical success was defined as > 90 % resolution of the stricture on follow-up pancreatogram. Results Eleven patients underwent a mean of 3.6 ERCPs (mean total diameter of 14.2 Fr of stenting) prior to CPL. Indications included pancreatic duct stricture (n = 8), pancreaticojejunostomy anastomotic stricture (n = 1), bile duct stricture (n = 1) and pancreatic intraductal papillary mucinous neoplasm ablation (n = 1). Immediate technical success was 94.1 % and short-term technical success rates was 88.2 %. At a mean follow-up of 12.1 months, there have been no stricture recurrences. Conclusions CPL may be an effective therapy for strictures refractory to conventional dilation and multiple stenting.
