Abstract
This study investigated the changes in echogenicity, as measured by endoscopic ultrasound, and the surface area of the papilla of Vater (PV) and their relationship with postoperative symptoms in a group of 80 patients with symptomatic gallstones before and at 3 and 6 months after cholecystectomy. After cholecystectomy, 50 patients experienced early atypical symptoms characteristic of postcholecystectomy syndrome (PCS) and 30 patients were asymptomatic. The surface area of the PV was larger than normal prior to surgery and increased after surgery. The healthy PV is isoechogenic, but 48% of all patients were anisoechogenic preoperatively, increasing to 61% at 3 months after surgery, and decreasing to 25% at 6 months postsurgery. There was no significant difference between the two patient groups, suggesting that the changes observed in the PV do not explain the presence of the atypical symptoms of PCS.
