Background: Pancreaticoduodenectomy or Whipples’s procedure is done for pancreatic, bile duct carcinoma, duodenal carcinoma and periampullary carcinoma. About 5% of the gastrointestinal malignancy is constituted by the ampullary and periampullary carcinoma. Histopathological studies related to the diagnosis, grade, stage, nodal status, marginal status, prognosis and incidence of these tumors are analyzed from the received Whipple’s specimen in our study. Aim of this study is to analyze the incidence of various tumors we encounter in the Whipple’s specimen, to calculate the sex ratio, to grade and to stage the tumors based on the WHO grading system. And to compare the incidence with other studies.
Methods: Histopathology records of all the patients who had Whipple’s resection during September 2013 - September 2015 were analyzed. The slides were reviewed and the parameters were calculated.
Results: Out of thirty cases, on which Whipple’s resection was done, twenty one had ampullary and periampullary carcinoma, The mean age incidence of ampullary carcinoma calculated was 44 years. The sex ratio of ampullary carcinoma was 1:1. Three had pancreatic tumors and six had chronic pancreatitis. Out of the three cases with pancreatic tumor, two had pancreatic endocrine tumors. They both were female. One had a Solid pseudopapillary pancreatic tumor. Literatures were reviewed and the predominance of ampullary carcinoma was noted in our study in contrast to other studies.
Conclusion: In the analysis of the Whipple’s specimen we found out that ampullary adenocarcinoma predominates and there were an equal sex incidence. This is in contrast to other published literatures. This variable needs further evaluation.
