    Abstract:
    BACKGROUND: Transduodenal ampullectomy has been attempted in ampullary tumors, including early ampullary cancer. However, the indication and extent of transduodenal ampullectomy with curative intent remain controversial. Herein, we address the perioperative and long-term outcomes of patients with early ampullary cancer who underwent transduodenal ampullectomy at a single center. METHODS: We retrospectively enrolled 10 early ampullary cancer patients who underwent transduodenal ampullectomy and 11 early ampullary cancer patients who underwent subtotal stomach-preserving pancreatoduodenectomy at Saitama Cancer Center between October 2008 and May 2021. Among this cohort, we analyzed the perioperative outcomes and long-term outcomes. RESULTS: In terms of the perioperative outcomes between the transduodenal ampullectomy and subtotal stomach-preserving pancreatoduodenectomy groups, the transduodenal ampullectomy group exhibited a shorter operating time (244 minutes vs 390 minutes, P = .003), less intraoperative blood loss (67.5 grams vs 774 grams, P = .006) and shorter length of postoperative hospital stay (15 days vs 33 days). With respect to the postoperative nutrition status, the transduodenal ampullectomy group exhibited less postoperative weight loss (0.67% vs 8.95%, P = .021), a better Controlling Nutritional Status score (1.0 vs 2.1, P = .011) and a better Prognostic Nutritional Index score (42.9 vs 40.9, P = .018). The 5-year survival in the adenoma with high-grade dysplasia and T1 ampullary cancer which invaded the mucosal layer groups was 100%, whereas the median survival time in the T1 ampullary cancer which invaded the sphincter of Oddi group was 20.7 months (P = .0028). CONCLUSION: Transduodenal ampullectomy is assumed to be a feasible and effective surgical procedure for the treatment of selected patients with early ampullary cancer, including patients with adenoma with high-grade dysplasia or T1 ampullary cancer which invaded the mucosal layer ampullary cancer.
