The aim of this work was to provide a critical analysis of the ten-year experience of using transpapillary interventions in an urgent surgical hospital with a detailed study of all groups of registered complications.Material and methods. In the period from 2008 to 2018, 1188 retrograde endoscopic transpapillary grafts were performed on the bile ducts with dissection of the major duodenal papilla in a typical and atypical way on the basis of our clinic. The group of observed patients included 1188 patients with endoscopic papillosphincterotomy, including 839 women (70.6%) and 349 men (29.4%). The average age was 63.2 ± 1.25.Results. During the period, 25 complications (2.1%) were revealed when performing transpapillary interventions with dissection of the major duodenal papilla: acute pancreatitis — 10 patients (0.8%); bleeding from the opening of the major duodenal papilla — 4 (0.33%), perforation 12p. intestines — 4 (0.33%), breakage of the basket cable with wedging — 1 (0.08%), cholangitis — 1 (0.08%), overlapping with a stent of the lobar duct — 1 (0.08%). The overall mortality associated with complications is 0.25%. Based on the analyzed material, the iatrogenic index was calculated. It was 0.044. After the analysis of complications, on the basis of the data obtained, we proposed an algorithm of actions when performing transpapillary interventions.Conclusion. Based on the study, we come to the conclusion that it will not be possible to completely level the risk and avoid possible papillotomic-induced complications. In this regard, the early, preferably intraoperative diagnosis of the latter and the prompt implementation of correlating therapeutic measures are of great importance, which will undoubtedly improve the treatment results and have a positive eff ect on the outcome of the disease.
