Abstract:
Objective:To study the safety and efficacy of combining portal vein resection and reconstruction (PVR) with resection of perihilar cholangiocarcinoma (PHC).Methods:A total of 104 patients with PHC who underwent hepatectomies for either biliary resection alone or biliary resection combined with PVR from October 2006 to December 2019 at the Department of Hepatopancreatobiliary, Ningbo Medical Center of Lihuili Hospital entered into this study. There were 63 males and 41 females, with the age of (64.4±10.4) years. The control group consisted of 75 patients who underwent biliary resection alone, while the PVR group consisted 29 patients with biliary resection combined with PVR. The patient characteristics and the follow-up outcomes of the two groups were analyzed and compared. Survival analyses were performed using the Kaplan Meier method with the log-rank test.Results:Wedge resection of portal vein, side to side anastomosis in 2 cases, segmental resection and end to end anastomosis in 27 cases. The time taken for PVR and portal vein resection were (12.7±2.9)(range 8 to 18)min and (20.7±7.3)(range 8 to 38) mm, respectively. The estimated blood loss for the PVR group was significantly more than the control group [ M( Q1, Q3)] 800.0 (600.0, 1 500.0) ml vs. 600.0(500.0, 1 000.0) ml ( P<0.05). Based on postoperative pathological studies, the proportion of lymph node metastasis was significantly higher in the PVR group than the control group (58.6% vs. 32.0%, P<0.05). Clavien-Dindo grade Ⅲ and above complications were 30.7%(23/75) and 34.5%(10/29) in the control and PVR groups, respectively ( P>0.05). The re-operation and postoperative 90 days mortality rates were 9.3%(7/75) and 2.7%(2/75) in the control group, compared with 3.4%(1/29) and 0 in the PVR group, respectively (both P>0.05). The 1-, 3- and 5-year survival rates were 81.1%, 44.8% and 36.4% respectively for the control group and 78.1%, 35.9% and 31.4% for the PVR group (χ 2=0.33, P=0.570). Conclusion:When compared to biliary resection alone, biliary resection combined with PVR did not significantly increase postoperative complication and mortality rates, but with comparable long-term survival outcomes. Combined biliary resection with PVR was safe and improved the resection rate in selected patients with locally advanced PHC.
