Mean values of factors with standard deviation were used. To compare mean values, Student\u2019s t-test was used. To compare non-parametric factors, the Chi-square test (\u03c72) was used. The value p&lt;0.05 was considered statistically significant. All calculation were performed with SPSSR version 19 (IBM, USA).\nResults: Biliary SOD was in 99 (82.5%) patients, mixed \u2013 bilio-pancreatic \u2013 in 21 (17.5%). Jaundice was in 59 (49.2%); dilatation of the common bile duct (CBD) was in 117 (97.5%); 18 (15%) patients had acute pancreatitis; 2 (1.7%) \u2013 cholangitis. All 117 (97.5%) patients with successful ERCP underwent ESP and\/or Precut. Disappearance\/reduction of abdominal pain was in 19 (90.5%) of 21 patients with pancreatic SOD, and in 60 (60.6%) of 99 patients with biliary SOD (\u03c72=6.872, p=0.009). Within 24-48 hours after ERCP, CBD size decreased from 10.9\u00b12.3 to 8.2\u00b11.7 mm (p&lt;0.001). After 72-96 hours total bilirubin level decreased from 43.8\u00b136.2 to 23.4\u00b114.3 \u03bcmol\/l (p&lt;0.001). Adverse events associated with ERCP were pancreatitis (14.2%), bleeding (1.7%) and cholecystitis (0.8%). Among the 21 patients with bilio-pancreatic SOD, no worsening of pancreatitis symptoms or onset of acute pancreatitis was observed. All cases of post-ERCP pancreatitis occurred exclusively in patients with biliary SOD (\u03c72=4.201, p=0.041).\nConclusions: In SOD with signs of cholestasis, ES leads to a decrease of CBD size and normalization of bilirubinemia. Elimination of abdominal pain immediately after ES is more typical for bilio-pancreatic SOD compared to biliary SOD. The most common adverse event after ERCP and ES in patients with SOD is acute pancreatitis \u2013 specific for biliary SOD and not typical for bilio-pancreatic SOD.<\/jats:p>","DOI":"10.36740\/merkur202604103","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T19:28:25Z","timestamp":1789154905000},"page":"389","source":"Crossref","is-referenced-by-count":0,"title":["Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy for sphincter of Oddi dysfunction: short-term results"],"prefix":"10.36740","volume":"54","author":[{"given":"Ivan","family":"Mamontov","sequence":"first","affiliation":[{"name":"KHARKIV NATIONAL MEDICAL UNIVERSITY, KHARKIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamara","family":"Tamm","sequence":"additional","affiliation":[{"name":"KHARKIV NATIONAL MEDICAL UNIVERSITY, KHARKIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kostiantyn","family":"Kramarenko","sequence":"additional","affiliation":[{"name":"KHARKIV NATIONAL MEDICAL UNIVERSITY, KHARKIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitro","family":"Riabushchenko","sequence":"additional","affiliation":[{"name":"KHARKIV NATIONAL MEDICAL UNIVERSITY, KHARKIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erika","family":"Bilousova","sequence":"additional","affiliation":[{"name":"KHARKIV NATIONAL MEDICAL UNIVERSITY, KHARKIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22436","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"1.
