ABSTRACT
Objective:To analyze the efficacy and prognosis of different surgical treatments for Bismuth-Corlette type III and IV hilar cholangiocarcinoma (HCCA).Methods:The clinical data of 86 Bismuth-Corlette type III and IV HCCA patients treated at the First Affiliated Hospital of Anhui Medical University from January 2010 to December 2016 were retrospectively analyzed. There were 45 males and 41 females with age of (59.5±10.5) years old. According to the operative method, 57 patients were included into the extended hepatectomy group, and 29 patients into the perihilar hepatectomy group. The perioperative clinical data and survival rates were compared between the two groups. Through inpatient interviews, regular outpatient or telephone follow-up, factors affecting prognosis were analyzed by univariate and multifactorial Cox regression.Results:The operative time and intraoperative blood loss in the extended hepatectomy group were significantly higher than those in the perihilar hepatectomy group, [320(270, 380) min vs. 270(210, 300) min, P<0.001; 300(200, 400) ml vs. 100(100, 150) ml, respectively P<0.001]. The incidences of ≥ Clavien-Dindo grade III complications and ISGLS grade C liver failure in the extended hepatectomy group were significantly higher than those in the perihilar hepatectomy group [36.4%(20/57) vs. 13.8% (4/29), P=0.037; 13.8% (7/57) vs. 0(0/29), respectively P=0.047]. The cumulative 1-, 3- and 5-year survival rates of the extended hepatectomy group were 89.5%, 38.6% and 19.3%, respectively. The cumulative 1-, 3- and 5-year survival rates of perihilar hepatectomy group were 86.2%, 20.7% and 10.3%, respectively. The difference between the two groups was statistically significant ( P=0.048). Multivariate analysis showed that perihilar hepatectomy ( HR=1.958, 95% CI: 1.174-3.268, P=0.010), non-R 0 resection ( HR=6.040, 95% CI: 2.915-12.513, P<0.001) and TNM stage III/IV( HR=2.144, 95% CI: 1.257-3.654, P=0.005) were independent risk factors for overall survival after surgery for HCCA patients ( P<0.01). Conclusions:Patients with Bismuth-Corlette type III and IV HCCA who received extended hepatectomy had significantly better overall survival than those patients who underwent perihilar hepatectomy. However, the incidences of surgical complications and liver failure in the extended hepatectomy group were also significantly higher.
ABSTRACT
Objective To study the effect of extended hepatectomy for hilar cholangiocarcinoma (HCCA) of the Bismuth-Corlette type Ⅲ and Ⅳ.Methods The clinical data of 73 patients with HCCA of the Bismuth-Corlette type Ⅲ and Ⅳ treated in our department from January,2008 to June,2016 were analyzed retrospectively.The extended hepatectomy group of patients consisted of 29 patients who underwent hepatectomy with half or more than half of the liver removed or/and combined with hepatic caudate lobectomy.The limited hepatectomy group consisted of 44 patients who underwent non-anatomical hepatectomy around the hepatic hilar region.Results Compared with the limited hepatectomy group,patients in the extended hepatectomy group had significantly longer operations with significantly more intraoperative blood loss.However,the complication rate was significantly lower than that of the limited hepatectomy group.There was no perioperative death in the extended hepatectomy group,while 3 perioperative deaths occurred in the limited hepatectomy group.The R0 resection rate was 93.1％ (27 of 29) for the extended hepatectomy group,while it was 54.6％ (24 of 44) for the limited hepatectomy group (P＜0.05).The 1-,3-and 5-year survival rates or the extended hepatectomy group were 81.4％,51.4％ and 19.3％,respectively while the corresponding rates for the limited hepatectomy group were 70.5％,24.4％ and 8.7％,respectively (P＜0.05).Conclusions After adequate preoperative radiological assessments on tumor resectability,and the residual liver volumes,with preoperative biliary drainage to improve liver function,extended hepatectomy effectively increased R0 resection and survival rates with improved prognosis for patients with HCCA of Bismuth-Corlette type Ⅲ and Ⅳ.
ABSTRACT
Objective To assess the safety and efficacy of extended liver resection using preoperative PTCD (percutaneous transhepatic cholangial drainage) and PVE (portal vein embolization) to treat patients with locally advanced hilar cholangiocarcinoma.Methods We collected and analyzed the clinical data of 27 patients with Bismuth types Ⅲ and Ⅳ hilar cholangiocarcinoma who underwent extended hepatecomy using preoperative PTCD and PVE in our hospital.Results There were 21 patients with R0 resection and 6 patients with R1 resection.The mortality rate was 0％.Eight patients died of cancer recurrence.Conclusion Preoperative PTCD and PVE combined with extended hepatectomy were safe and efficacious in treating patients with locally advanced hilar cholangiocarcinoma,which resulted in potential cure.
ABSTRACT
Objective:To investigate the clinical efficacy of extended hepatectomy for hilar cholangiocarcinoma (HCCA) of Bismuth-Cor-lette typesⅢandⅣ(the longitudinal invasion degree along the biliary system is the main criteria). Methods:The clinical data of 61 patients with HCCA of Bismuth-Corlette types III and IV admitted in the Department of Hepatobiliary Surgery of the First Affiliated Hos-pital of Bengbu Medical College from January 2008 to May 2015 were analyzed retrospectively. Among the 61 cases, 22 underwent hepatectomy with half or over half of the liver removed or hepatic caudate lobectomy (regarded as the extended hepatectomy group), whereas 39 cases underwent irregular hepatectomy on the hepatic hilar region (regarded as the limited hepatectomy group). Results:Compared with those in the limited hepatectomy group, the patients in the extended hepatectomy group underwent longer duration of operation and experienced more bleeding during the procedure. The complication incidence rate for the extended hepatectomy group was lower than that for the limited hepatectomy group. No patient died during the perioperative period in the extended hepa-tectomy group, whereas two patients died in the limited hepatectomy group. Moreover, R0 resection was performed on 21 cases in the extended hepatectomy group, with a resection rate of (21/22) 95.5%, and on 20 cases in the limited hepatectomy group (P<0.05), with a resection rate of (20/39) 51.3%. Actuarial 1-, 3-, and 5-year survival rates were 77.27%, 36.36%, and 13.64%, respectively, in the extended hepatectomy group, and 69.23%, 20.51%, and 1.64%, respectively, in the limited hepatectomy group (P<0.05). Conclusion:Extended hepatectomy for patients with HCCA of Bismuth-Corlette typesⅢandⅣcould effectively increase the resection rates of R0 and the survival rate. Meanwhile, the prognosis of patients could be improved.
ABSTRACT
Objective To investigate the effect of selective bowel decontamination (SBD) on prognosis of 90％ hepatectomy in rats.Methods We adopted rat model of subtotal hepatectomy(90％,SHx),gentamicin + polymyxin + nystatinor saline of the same amount was administrated preoperatively.Liver damage makers,portal and systemic lipopolysaccharide(LPS),mucosal damage,signaling pathways and liver regeneration were investigated.Results We found that SHx resulted in significantly enhancedsystemic LPS.Inhibition of gastrointestinal gram-negative bacteria by SBD significantly reduced LPS levels and improved survival after SHx.SBD protected intestinal mucosa barrier,alleviated liver parenchymal damage and inflammation and promoted liver regeneration.Conclusion SBD is beneficial and necessary for extended heptactomy.
