Abstract		Background and study aims To date, little is known about changes in the size of the papilla of Vater in patients with gallstones. Most of the research concerning these patients has investigated changes in the diameter of the common bile duct and pressure in the sphincter of Oddi region. The latest research has not confirmed the prevalent opinion that the common bile duct dilates after cholecystectomy; moreover, knowledge about changes in the form and size of the papilla of Vater remains poor. The aim of our research was to measure the surface of the papilla of Vater and the diameter of the periampullary pancreatic part of the common bile duct before surgery, then 3 months and 6 months after surgery, using endoscopic ultrasound. Patients and methods In patients with symptomatic gallstones but with no evidence of cholestasis or stones in the common bile duct, the surface of the papilla of Vater and the diameter of the periampullary pancreatic part of the common bile duct were measured before surgery by endoscopic ultrasound. In the postoperative period, measurements were repeated in patients with an early occurrence of nausea, distension, bloating and pain in the upper abdomen and in patients without any symptoms in the same time period. The surface of the normal papilla of Vater and the diameter of the periampullary pancreatic part of the common bile duct were determined in healthy subjects. Results In all the patients included in our study, the surface of the papilla of Vater was enlarged before surgery and, after 3 months, was even larger. However, after 6 months, it was practically the same as before surgery. The diameter of the periampullary pancreatic part of the common bile duct before surgery and 6 months after surgery was within normal limits. However, a statistically significant and transient increase in the diameter was noticed in the third month after cholecystectomy. (Abstract truncated at 2000 characters).
