[Endoscopic resection of ampullary adenoma.].

Ampullary adenomas can occur sporadically or as part of familial adenomatous polyposis syndrome. Most of them are asymptomatic. Current standard of management is complete surgical or endoscopic resection, depending on depth of invasion and/or biliary tract involvement. The last can be established by endoscopic ultrasound or endoscopic retrograde colangiopancreatography. Surgical resection has high morbidity (25% to 65%) and mortality (10%) in unexperienced hands compared to endoscopic therapy (12% and 1%, respectively). Complications of endoscopic therapy ranges from 7% to 10%. Recurrence of adenomatous lesions treated endoscopically is 30%. Endoscopic surveillance after resection is mandatory. We present the case of a patient with an ampulla of Vater s adenoma successfully resected endoscopically previous assessment of the lesion by endoscopic ultrasound.
