Surgical management of hilar cholangiocarcinoma / 中华消化外科杂志

ABSTRACT

Objective To summarize the experience in surgical management of hilar cholangiocarcinoma.Methods The clinical data of 88 patients with hilar cholangiocarcinoma who received surgical treatment at the First Affiliated Hospital of Harbin Medical University from January 2007 to December 2011 were retrospectively analyzed.All the patients were diagnosed by imaging examination.According to the severity of jaundice and predictive remnant liver volume,19 patients received percutaneous transhepatic cholangial drainage (PTCD) and 4 received portal vein embolization.The fundamental operation consisted of hilar cholangiocarcinoma resection,skeletonization of hepatoduodenum ligament and Roux-en-Y cholangiojejunostomy,and the transanastomotic stent was placed for 6 months.The count data were analyzed using the chi-square test; the survival rate was analysed using the Kaplan-Meier method; the survival was analyzed using the Log-rank test.Results Of the 88 patients,58 patients (including 11 patients who received PTCD) received hilar cholangiocarcinoma resection.Of the 58 patients,43 (including 4 patients who received portal vein embolization preoperatively) received R0 resection,and 15 received palliative resection.Thirty patients received internal and (or) external drainage.Commitant partial hepatectomy was performed on 22 patients (including 9 received left hemihepatectomy,2 received extended left hemihepatectomy,7 received left hemihepatectomy + caudate lobectomy,4 received right hemihepatectomy).Commitant pancreatico-duodenectomy was performed on 7 patients,commitant hepatic artery resection on 3 patients,and commitant portal vein resection on 2 patients.According to the modified Bismuth-Corlette classification,there were 17 patients with type Ⅰ,19 with type Ⅱ,21 with type Ⅲa,20 with type Ⅲb,and 11 with type Ⅳ.Of the 58 patients who received hilar cholangiocarcinoma resection,19 had postoperative complications,and 2 patients died within 30 days after operation.Seventy-three patients were followed up,and the overall 1-,3-,5-year survival rates were 68.5％,28.8％,11.0％,respectively.The 1-,3-,5-year survival rates of patients who received R0 resection were 94.6％,43.2％,18.9％,respectively,which were significantly higher than 78.6％,35.7％ and 7.1％ of patients who received palliative resection (x2=4.77,P ＜0.05).The 1-,3-,5-year survival rates of patients who received palliative resection were significantly higher than 18.2％,0,0 of patients who received biliary drainage (x2 =13.26,P ＜ 0.05).Conclusions R0 resection is the best choice for patients with hilar cholangiocarcinoma,and biliary drainage with no resection is the last choice.Sufficient preoperative treatment,optimized choice of surgical procedure and exquisite surgical techniques are important for the improvement of the prognosis.
