Periampullary tumors: which ones should be resected?

Area of Science:

• Gastroenterology
• Surgical Oncology
• Oncology

Background:

• Periampullary lesions encompass tumors near the ampulla of Vater, including those of the pancreas, bile duct, and duodenum.
• Adenocarcinomas are the most common malignant periampullary tumors, often presenting diagnostic challenges.
• Surgical resection is the primary curative treatment for resectable periampullary lesions.

Purpose of the Study:

• To evaluate the outcomes of surgical resection for periampullary lesions.
• To compare the efficacy of different surgical approaches, including the Whipple operation, total pancreatectomy, and local resection.
• To assess the diagnostic accuracy of preoperative evaluations for pancreatic head carcinoma.

Main Methods:

• Retrospective analysis of 118 patients undergoing resection for periampullary lesions.
• Categorization of lesions into adenocarcinomas and other types.
• Documentation of surgical procedures performed (Whipple, total pancreatectomy, local resection).
• Review of preoperative diagnostic accuracy and postoperative mortality and survival rates.

Main Results:

• Ninety-eight of 118 patients had adenocarcinomas, predominantly treated with the Whipple operation (87 patients).
• Preoperative diagnosis of pancreatic head carcinoma was falsely positive in 27% of cases.
• Mortality for radical resection was 4%, with a 5-year survival of 32% for ampullary carcinoma and 7% for pancreatic head carcinoma.

Conclusions:

• Resection of all periampullary tumors is recommended due to potential curability.
• The Whipple operation remains the standard surgical procedure for most periampullary adenocarcinomas.
• Improved preoperative diagnostic accuracy is needed, especially for pancreatic head carcinoma.
