title: [The value of endoscopic biopsy in the diagnosis of carcinoma of Vater's ampulla].
abstract: In a series of 23 ampullary carcinomas, confirmed by the pathological examination of the duodenopancreatectomy specimens, 17 were biopsied during the previous ERCP examination. Biopsies were diagnostic of carcinoma in 12 (70.5%). Among 11 exophytic tumours biopsy was positive in 8 (72.7%) while in 6 tumours growing inside the papilla biopsies were positive in 4 (66.6%) (NS). It is concluded that endoscopic biopsy may be diagnostic in two-thirds of ampullary carcinomas.
