    Abstract:
    BACKGROUND: Carcinoma of the ampulla of Vater has a more favorable prognosis, compared to other malignant tumors of the periampullary region, because it usually presents with symptoms in the early stage. However, treatment by local resection only of the ampullary carcinoma remains controversial. The aim of this study was to evaluate the treatment results of the ampulla of Vater carcinoma according to different types of operation in low-risk-group patients. METHODS: We retrospectively reviewed the medical records of 17 low-risk-group patients among a total of 102 patients with ampulla of Vater carcinoma who had underwent curative surgery from 1992 to 2002. All specimens were critically reviewed by a single expert pathologist, and the relationship between surgical outcomes and operation type was assessed. RESULTS: The low-risk group was comprised of 10 men and 7 women with a median age of 57.8 years. Thirteen of 17 patients underwent a pancreaticoduodenectomy (PD) or a pylorus preserving pancreaticoduodenectomy (PPPD), while 4 patients underwent a transduodenal local resection (TDLR). The operation time was significantly shorter in the TDLR group, compared to the PD or PPPD groups. Among the 17 patients, there was only 1 case of recurrence in the inguinal area 33 months after the pancreaticoduodenectomy. CONCLUSIONS: Transduodenal local resection is a comparable mode of operation for low-risk-group patients with Ampulla of Vater carcinoma. In particular, it is essential to evaluate the invasion depth in preoperative endoscopic ultrasonography, cell differentiation in preoperative biopsy, and positivity of resection margin accurately by using frozen section during the operation.
