VASCULAR RESECTION DURING SURGICAL RESECTION FOR ADVANCED GALLBLADDER CARCINOMA

We evaluated the results of vascular resection during surgical resection for advanced gallbladder carcinoma. Twelve patients underwent vascular resection (portal vein in 11, hepatic artery in 2, inferior vena cava in 2) in 58 resected patients with advanced gallbladder carcinoma (stage III and IV). The surigical rate was higher in the nonvascular resection group (61％) than in the vascular resection group (25％) (P＜0.05). Surgical morbidity and mortality rates were not significantly different between the two groups. The survival rate was remarkably higher in the curative resection group (n＝29) (55.6％ at 1 year, 30.3％ at 3 years, 20.8％ at 5 years) than in the noncurative resection group (n＝29) (26.3％ at 1 year, 0％ at 2 years) (P＜0.05). Survival rates of the nonvascular resection group (n＝46) were 45.3％ at 1 year, 23.4％ at 3 years, and 16.1％ at 5 years. However, no patient in the vascular resection group (n＝12) survived longer than 2 years.
In conclusion, vascular resection during surgical resection for advanced gallbladder carcinoma does not result in a more favorable prognosis, despite similar surgical risk as in nonvascular resection procedures.
