Abstract

Background

Early and late outcomes after superior mesenteric-portal vein resection (VR) combined with pancreaticoduodenectomy, major hepatectomy, or both for pancreaticobiliary carcinoma were retrospectively evaluated. VR is the most frequently used vascular procedure in this field, but an exact role of VR has not been compared according to the primary site of tumor.

Materials and Methods

Postoperative outcomes were compared between surgery with and without VR in each of the three disease-based groups: hilar cholangiocarcinoma and intrahepatic cholangiocarcinoma with hilar extension (HIC, 56), middle and distal cholangiocarcinoma and gallbladder carcinoma (DGC, 118), and pancreatic head adenocarcinoma (PHC, 77).

Results

VR was performed in 19.6% of HIC, 8.5% of DGC, and 45.5% of PHC. In-hospital death was 7.1% (4 of 56) patients with VR (3 of DGC and 1 of PHC). Operations with VR in DGC showed a larger amount of blood loss and more increased ratio of R1operation than those with no VR. In HIC, DGC, and PHC, median survival time of patients with VR was 37, 6.8, and 20 months and that of patients without VR was 42.9, 28.6, and 20.3 months, respectively. VR did not affect survival either in HIC or in PHC; however, in DGC, VR was accompanied with dismal outcome compared with no VR (p = 0.001).

Conclusions

Aggressive surgery with VR can be justified both in HIC and in PHC but should not be recommended for DGC. Surgical outcomes of VR differed considerably, depending on the sites of the primary tumor.
