Most noninvasive ampullary tumors of the major papilla occur as sporadic and asymptomatic lesions, detected during conventional upper endoscopy performed for another indication.\n\nNonetheless, they can present with jaundice (17%), pain (14%), pancreatitis (4%), cholangitis (1%), and can be associated with common bile duct stones (up to 38%). Resection of ampullary adenomas is warranted to prevent malignant progression. The most recent European Society of Gastrointestinal Endoscopy (ESGE) recommend endoscopic ampullectomy as the standard of care approach for ampullary adenomas without intraductal extension, due to excellent outcomes of technical and clinical success (high complete and curative resection rates of 94% and 87%, respectively), with lower morbidity and recurrence rates. This procedure as a low rate of mortality (of 0.4%), but the rate of adverse events can exceed 20%. The most frequent adverse events are acute pancreatitis (12%), intraprocedural and\u002For delayed bleeding (11%), perforation (3%), cholangitis (3%), ampullary stenosis (2.5%). Also there is a high recurrence rate of up to one third after endoscopic resection; up to two thirds are identified at the first follow-up endoscopy, requiring additional endoscopic resection or surgery.",[38,39],"Ampulla of Vater Adenoma","Ampulla of Vater Disease (Benign\u002FMalignancy)","NOT_YET_RECRUITING","2024-10-16",{"date":43,"type":44},"2024-10-18","ACTUAL",{"date":46,"type":34},"2024-12",{"date":46,"type":34},{"name":5,"class":6}]
