Aims Indirect peroral cholangiopancreatoscopy (IPOC) is a new diagnostic and therapeutic tool for biliopancreatic diseases. Little is known about its use in daily clinical practice. We conducted an international survey to evaluate differences in use of IPOC between endoscopists from various countries.

Methods An online survey was developed comprising 66 questions regarding the experience, technique and biliopancreatic indications of IPOC. The survey was sent to members of the European and German Cholangioscopy Group, and authors who published on IPOC in the past 5 years.

Results Eighty-three respondents completed the survey, from 23 countries across Europe and the Middle-East. Twenty respondents (24.1%) performed >100 cholangioscopies lifetime and 4 (4.8%) >100 pancreatoscopies lifetime. Main indications for cholangioscopy were determination of indeterminate biliary strictures (n=81 (97.6%)) and removal of bile duct stones (n=75 (90.4%)), accounting for an estimated use of 40% (IQR 32.5) and 40% (IQR 40), respectively. Eleven respondents (13.9%) have an institutional standardized protocol for targeted cholangioscopy-guided biopsy sampling. Twenty-seven respondents (36%) use IPOC with lithotripsy as first-line treatment in selected patients with bile duct stones. Electrohydraulic (EHL), laser lithotripsy (LL) or both tools are used by 46 (61.3%), 17 (22.7%) and 12 (16%) respondents, respectively.

Pancreatoscopy is used for removal of pancreatic duct stones, determination of pancreatic duct strictures and delineation of intraductal papillary mucinous neoplasm, by 63 (75.9%), 38 (45.8%) and 30 (36.1%) respondents, respectively. Removal of pancreatic duct stones accounts for an estimated use of 78% (IQR 45) use. EHL, LL or both tools are used by 43 (68.3%), 12 (19.1%) and 8 (12.7%) respondents, respectively.

Conclusions This is the first international survey on the clinical practice of IPOC, showing a wide variation in use of IPOC. These results emphasizes the need of studies and development of an international consensus guideline to standardize the practice and quality of IPOC.
