Transduodenal local resection for low-risk group ampulla of Vater carcinoma

Abstract

Purpose: A carcinoma of the ampulla of Vater has more favorable prognosis than other malignant tumors of the periampullary region, because it is symptomatic at an early stage. However, local resection of an ampullary carcinoma remains controversial. The aim of this study was to evaluate the treatment results of ampulla of Vater carcinomas, according to operation type in low risk group patients. Methods: The records of 17 low risk group patients, among 120 patients with ampulla of Vater cancer, who underwent curative surgery beyween 1992 and 2002, were reviewed. All specimens were critically reviewed by a single expert pathologist. The relationship between surgical outcomes and operation type were assessed. Results: There were 10 men and 7 women, with a median age of 57.8 years. 13 of the 17 patients underwent the Whipples operation or a PPPD, and 4 underwent a transduodenal local resection (TDLR). The operation time was shorter in the TDLR group, and was statistically significant. Among the 17 patients, only one had a recurrence in the inguinal area 33 months after the PD. Conclusion: Transduodenal local resection is a recommendable operation for low risk Ampulla of Vater cancer patients. During the operation, it is essential to accurately evaluate the depth of invasion, cell differentiation and positivity of the resection margin using frozen sections.
