Abstract


Background: The aim of this study was to comprehensively analyse the histopathological spectrum of pancreatobiliary tumors with special reference to ampulla of Vater.

Methods: The retrospective study was done for 5 years and a prospective study was carried out for 2 years in the Department of Pathology.

Results: A total of 110 cases were included; 103 underwent a standard Whipple procedure and 7 underwent localised resection (partial pancreatectomy). The average age was 52.64 years (16-80 years) and males outnumbered females (3:2). Malignant (93.63%) lesions outweighed benign lesions (6.36%). Among malignant lesions, 71 (68.93%) were peri-ampullary, 15 (14.56%) were pancreatic, 11 (10.67%) were duodenal and only 6 (5.825%) were cholangiocarcinoma. The most common presenting feature was jaundice followed by pain in the abdomen. The mean tumor size was 2.38 cm (0.5-15cm). The pathological stage of most of the tumors was T2 (58.2%), followed by T3 (22.7%), T1 (11.8%) and T4 was only 1.8%. Proximal duodenal resection margin was free in 90.9%, distal duodenal resection margin was free in all cases, CBD resection margin was involved in only 2 cases (1.8%), while the pancreatic duct resection margin was involved in 2.7%. The nodal status was N0 in 61.8%, N1 in 23.6% and Nx in 9.1%.

Conclusions: Adenocarcinoma (well differentiated-47.3%) is the most common histological variant of pancreatobiliary region.
