ENDOSCOPIC PAPILLECTOMY FOR EARLY AMPULLARY NEOPLASTIC LESIONS - A CASE SERIES ANALYSIS.

Endoscopic papillectomy allowed for technical successful procedure with complete removal of ampullary neoplastic lesions in the majority of cases with acceptable adverse event rates. Recurrence rate should be carefully assessed in further studies. There was a recent increase in the number of procedures. There was also a low correlation between pre- and post-histopathological assessment regarding the presence of invasive carcinoma and adenoma with high grade dysplasia, with a predominance of superficial neoplastic adenomatous lesions.
