ObjectiveTo explore the technique of hepatic artery reconstruction in complicated hilar cholangiocarcinoma surgery. MethodThe clinicopathologic data of 3 patients with complicated hilar cholangiocarcinoma with arterial invasion underwent hepatic artery reconstruction in the Department of Hepatopancreatobiliary Center of Beijing Tsinghua Changgung Hospital from March to July 2022 were retrospectively analyzed. ResultsAll 3 patients (case 1–3) were the males, aged 53, 68, and 56 years, respectively, and with hypertension or diabetes; the longitudinal diameters of the tumor were 3.5 cm, 3.0 cm, and 3.2 cm, respectively. All patients had the right hepatic artery invasion. Case 2 and 3 had the arterial stratification. The arterial defects after radical resection were 4.5 cm, 3 cm, and 3 cm, respectively. The right or right posterior hepatic artery was reconstructed by the autotransplantation of right gastroomental artery, the left hepatic artery, and the anterior superior pancreaticoduodenal artery, respectively. After operation, the reconstructed hepatic arteries were unobstructed and free of stenosis, and there were no complications such as bleeding, infection, and thrombosis by Doppler ultrasound and CT angiography. The results of postoperative pathological diagnosis were the hilar cholangiocarcinoma with arterial invasion, and all the incisal edges were negative. ConclusionFrom the preliminary results of 3 cases, it is safe, feasible, and effective to select proper autologous artery (matched in length and caliber) for reconstruction the defective invaded hepatic artery which resected together with hilar cholangiocarcinoma, but the technical difficulty is still relatively high.
ObjectiveTo summarize the surgical treatment and explore factors which influencing prognosis of hilar cholangiocarcinoma. MethodsClinical data of 189 cases of hilar cholangiocarcinoma who treated in our hospital from Jan. 2000 to Dec. 2010 and clinicopathological factors that might influence survival were analyzed retrospectively. A multivariate factor analysis was performed through Cox proportional hazard model. ResultsOf 189 cases, 62 cases received radical resection, 54 cases received palliative surgery, and 73 cases received non-resection surgery. Operative procedure (RR=0.165), differentiated degree (RR=2.692), lymph node metastasis (RR=3.014), neural infiltration (RR=2.857), and vascular infiltration (RR=2.365) were found to be the statistically significant factors that influenced survival by multivariate factor analysis through the Cox proportional hazard model. ConclusionsRadical resection is the best treatment for hilar cholangiocarcinoma. Skeletonized hepatoduodenal ligament, complete excision of infiltrated nerve and blood vessel are important influence factors to improve the prognosis of hilar cholangiocarcinoma.
ObjectiveTo understand the current situation of surgical treatment of hilar cholangiocarcinoma. MethodThe literature relevant to surgical treatment of hilar cholangiocarcinoma at home and abroad in recent years was reviewed. ResultsThe various surgical treatment schemes of hilar cholangiocarcinoma had advantages and disadvantages. At present, there were still disputes and no unified consensus on preoperative preparation, selection of intraoperative surgical resection range, and applications of laparoscopy and robot, etc. The individualized surgical treatment plan should still be formulated based on the specific condition of the patient and the professional experience of the surgeon. The individualized surgical treatment plan should still be formulated based on the specific condition of the patient and the professional experience of the surgeon. ConclusionIt is believed that accurate preoperative condition evaluation should be carried out for each patient with hilar cholangiocarcinoma, so as to formulate the best surgical treatment plan, achieve individualized accurate treatment and benefit patients.
ObjectiveTo summarize the clinical experience of 58 operations for biliary malignant tumor with da Vinci surgical system. MethodsFrom January 2009 to October 2010, 180 patients with hepatopancreaticobiliary and gastrointestinal disease underwent robotic surgeries by using da Vinci surgical system, including 58 patients with biliary malignant tumor. The case distribution, intra and postoperative data were analyzed. ResultsOf 58 patients, 3 patients with intrahepatic bile duct cystadenocarcinoma received wedge resections of liver. In 36 patients with hilar cholangiocarcinoma, anatomical left hemihepatectomies were performed in 3 cases, resection of extrahepatic duct and gallbladder bridge type biliary revascularization in 3 cases, resection of extrahepatic duct and biliary-enteric Roux-en-Y anastomosis in 14 cases, tumor resection and revascularization of hepatic portal bile duct in 1 case, palliative external drainage of intrahepatic bile duct in 5 cases, and Y-internal drainage of hepatic portal in 10 cases. In 10 patients with gallbladder carcinoma, resection of extrahepatic duct and gallbladder and biliaryenteric Roux-en-Y anastomosis in 2 cases, cholecystectmy in 3 cases, cholecystectmy and external drainage of intrahepatic bile duct in 1 case, cholecystectmy and Y-internal drainage by suspension of hepatic portal in 4 cases. A patient with middle bile duct cancer received radical resection of cholangiocarcinoma and biliary-enteric Roux-en-Y anastomosis. Of 8 patients with distal bile duct cancer, Whipple procedure were performed. Of 58 patients, 2 cases converted to hand-assistant procedure (3.4%). For all patients, operation time was (6.18±1.71) h, blood loss was (116.66±56.06) ml, blood transfusion was (85.55±38.28) ml, ambulation time was (9.10±2.91) h, feeding time was (14.95±4.35) h, and hospital stay was (12.81±4.29) d. Postoperative complications occurred in 8 cases (13.8%), including bile leakage (3 cases), wound bleeding (1 case), pancreatoenteric anastomotic leakage (2 cases), pulmonary infection (1 case), and renal failure (1 case). Of these 8 cases, 6 cases recovered smoothly and 2 cases die of severe pulmonary infection and renal failure after conservative treatment (3 or 4 weeks), therefore, the mortality of patients was 3.4%. In 36 patients with hilar cholangiocarcinoma, 19 cases died (on 2 monthes 4 cases, on 6 monthes 5 cases, on 10 monthes 8 cases, and on 12 monthes 2 cases after operation), 11 cases survival well (gt;26 monthes 4 cases, gt;22 monthes 3 cases, and gt;19 monthes 4 cases), and 6 cases required hospitalization. Of 10 patients with gallbladder carcinoma, 7 cases died (on 3 monthes 1 case, on 5 monthes 1 case, on 8 monthes 1 case, on 11 monthes 3 cases, and on 12 monthes 1 case after operation) and 3 cases survival (gt;17 monthes 2 cases, gt;13 monthes 1 case). In 8 cases undergoing pancreatoduodenectomy, 5 cases died (on 4 monthes 2 cases, on 6 monthes 2 cases, and 10 monthes 1 case after operation) and 3 cases survived well over 2 years. Three patients with intrahepatic bile duct cystadenocarcinoma survived over 1 year. Conclusionsda Vinci surgical system can carry out all kinds of surgery for biliary malignant tumor, especially prominent in the complicated surgeries for hepatic portal, which breaks through the restricted area of laparoscope in hepatobiliary malignant tumor.
Objective To investigate the strategy of treatment and prevention of hemorrhage after radical resection of hilar cholangiocarcinoma. Method Reviewing the related literatures at home and abroad in recent years, to summarize the progress of treatment and prevention of hemorrhage after radical resection of hilar cholangiocarcinoma. Results We should clear the postoperative bleeding time, extent, cause, and location, to help the clinician to choose the appropriate timing of intervention and treatment. The patients with early hemorrhage and mild degree hemorrhage could be treated conservatively. If patients with severe hemorrhage and hemodynamic disorders, surgical intervention must be decisive. Patients with late hemorrhage would have serious consequences, and these patients should receive interventional or surgical treatment as early as possible. Conclusions For patients with hilar cholangiocarcinoma after radical resection, doctors need to do accurate preoperative evaluation, meticulous operation, and intensive management after operation, to reduce the incidence of hemorrhage after radical resection of hilar cholangiocarcinoma. If the postoperative hemorrhage occurs, the cause, location, time, and degree of hemorrhage should be clearly defined to facilitate clinicians to make rapid clinical decisions and to develop treatment programs.
