Functional Status of the Palate of Fater During VEGDS in Bile Duct Reconstructive Operations (Literature Review)

Reconstructive surgeries on the biliary tract, especially with choledochoduodenostomy and other anastomoses, can cause changes in the functional state of the papilla of Vater.These changes can affect the regulation of bile flow, intestinal motility, as well as infectious and stenotic complications of the biliary tract.The aim of this study is to evaluate the functional state of the papilla of Vater using video esophagogastroduodenoscopy (VEGDS) after reconstructive surgeries on the biliary tract.During the study, pathological changes such as papilla patency, spasm, reflux and stenosis were analyzed in patients.The results showed that after reconstructive surgeries, some patients have hypofunction or hypertonicity of the papilla of Vater, which increases the risk of biliary stasis and chronic cholangitis.VEGDS plays an important role in the early diagnosis of these complications in the postoperative period and the choice of treatment.
