Radiofrequency ablation for intraductal extension of ampullary adenomatous lesions

Abstract Text We present a case of a 71-year-old male with abdominal pain, hyperbilirubinemia, weight loss, and night sweats. MRCP revealed biliary sludge and a suspicious periampullary lesion. Duodenoscopy showed a 12 mm polypoid lesion in the ampulla of Vater, which was biopsied. ERCP identified dilated bile ducts and a distal stricture. Following sphincterotomy and balloon bile duct exploration, microlithiasis was expelled. Histology of the lesion confirmed intestinal-type adenoma with low-grade dysplasia. The patient underwent successful endoscopic ampullectomy. Three months later, a diminutive polypoid lesion was detected at the distal common bile duct and biopsied, confirming a tubular adenoma. Radiofrequency ablation was performed, and the patient has been lesion-free for 2 years. This case highlights endoscopic papillectomy and the role of radiofrequency ablation in managing recurrent lesions [1].
