RESUMO
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.
RESUMO
Objective:To investigate the clinical efficacy of perihilar surgical techniques for diffuse hepatolithiasis.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 122 patients with diffuse hepatolithiasis who were admitted to Hunan Provincial People's Hospital from January 2010 to December 2015 were collected. There were 39 males and 83 females, aged from 21 to 82 years, with a median age of 51 years. After perihilar hepatectomy, the first, second and third divisions of hepatic ducts were opened longitudinally. Strictures in the bile ducts were relieved by stricturoplasty and internal bile duct anastomosis, and stones were removed by multiple methods under direct vision. After resection of severe atrophic liver segment along the plane of hepatic atrophy or bile duct stricture, T-tube or hepaticojejunos-tomy was used for internal drainage. Observation indicators: (1) surgical situations; (2) stricture relief and stone removal. (3) Follow-up. Follow-up was conducted by Wechat, telephone interview or outpatient examination. Patients were followed up once every 3 months in the postoperative 1 year through liver function and abdominal B-ultrasound examination. Subsequently, liver function and abdominal B-ultrasound were reexamined once a year. Magnetic resonance cholangiopancreato-graphy and computed tomography were performed when cholangitis or stone recurrence was suspected to analyze stone recurrence and patient survival. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers or percentages. Results:(1) Surgical situations: for the 122 patients, the operation time, hepatic portal occlusion time, volume of intraoperative blood loss, duration of postoperative hospital stay were (253±71)minutes, 15 minutes(range, 14?38 minutes), 200 mL(range, 100?1 100 mL), (12±5)days. Postoperative complications occurred to 40 of 122 patients. There were 9 cases of incision infection, 8 cases of bile leakage (5 cases of bile leakage at hepatic section, 3 cases of choledochojejunostomy leakage), 8 cases of septicemia, 7 cases of pleural effusion, 5 cases of abdominal abscess, 3 cases of liver failure, 1 case of biliary bleeding. Some patients had multiple complications. Among the 122 patients, 2 cases died after operation, including 1 case of postoperative liver failure and 1 case of disseminated intravascular coagulation caused by biliary-intestinal anastomotic leakage complicated with sepsis. Patients with bile leakage and abdominal abscess were improved after puncture and drainage under the guidance of B-ultrasound. Patients with cholangiojejunal anastomotic bleeding were embolized through the right hepatic artery. The other complications were improved after conservative treatment. (2) Stricture relief and stone removal: 85 of 88 patients with biliary stricture were relieved, with the stricture relief rate of 96.59%(85/88). Among the 122 patients, 103 cases had stones completely removed and 19 cases had residual stones. The immediate stone clearance rate was 84.43%(103/122). Of the 19 patients with residual stones, choledochoscopy was refused in 3 cases and choledochoscope lithotripsy was performed in 16 cases, of which 7 cases were removed and 9 cases were still residual stones. Of the 122 patients, 110 cases were finally removed stones, 12 cases were eventually residual stones, and the final stone clearance rate was 90.16%(110/122). (3) Follow-up: among the 122 patients, 120 cases including 110 cases with find stone removal and 10 cases with residual stones were followed up for (78±14)months. The 1-, 3, 5-year stone recurrence rates of 120 patients were 0.83%(1/120), 6.67%(8/120), 9.17%(11/120), respectively. The 1-, 3-, 5-year stone recurrence rates of 110 patients with final stone removal were 0, 5.45%(6/110), 5.45%(6/110), respectively. The number of cases with stone recurrence at postoperative 1-, 3- and 5-year of 10 patients with residual stones were 1, 2, 5 cases, respectively. Of 120 patients with follow-up, 1 case died of end-stage liver disease, and the other patients had good survival.Conclusion:Perihilar surgical techniques for diffuse hepatolithiasis is safe and effective.
RESUMO
Background: Stone recurrence is a major problem limiting the effects of surgical treatment for hepatolithiasis. It was showed that hyperplasia of perihilar liver may compress the hepatic portal and cause deficient bile flow because of compressed hilar bile duct, thereby leading to the formation of bile stasis and precipitating stone recurrence. This retrospective study aimed to evaluate the efficiency of perihilar hepatectomy for hepatolithiasis with compressed hilar bile duct induced by perihilar hyperplasia of liver. Methods: 135 patients with compressed hilar bile duct induced by hypertrophied perihilar liver were included in this study from January 2011 to July 2016. Among these patients, 77 underwent conventional operation procedure (control group) and 58 underwent conventional operation procedure added by perihilar hepatectomy (perihilar hepatectomy group). Clinical data containing preoperative data, intraoperative data, operation complications, and short-term and long-term outcomes were collected. Results: The demographic and disease-related characteristics of the two groups were comparable. The two groups were not remarkably different in operation-related characteristics. The incidence of bile leakage in the perihilar hepatectomy group was substantially higher than that in the control group. Other postoperative complications were not remarkably different between the two groups. In the long-term postoperative follow-up period, the incidence of the recurrence of stones and cholangitis in the control group was considerably higher than that in the perihilar hepatectomy group. Conclusions: Based on conventional operation procedure, additional perihilar hepatectomy is a reliable intervention with definite clinical effects for hepatolithiasis with compressed hilar bile duct induced by hypertrophied perihilar liver.
