Numbers before each author’s name express number of patients reported with a given individual ESCP approach by the author in the referenced article. A total of 19 patients were drained by transpapillary ESCP rendezvous (7 pancreatic, 12 biliary) and 16 transmurally (4 pancreatic, 12 biliary). The dominant approaches were pancreatic rendezvous (7 patients from 4 centers) and chole-dochoduodenstomy (9 patients from 4 centers). ^*Methylene-blue EUS-guided pancreatography with subsequent non rendezvous ERCP.
