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.
Objective
To explore safety and efficacy of total laparoscopic radical resection of hilar cholangiocarcinoma.
Methods
From April 2016 and January 2017, 6 patients with hilar cholangiocarcinoma underwent laparoscopic radical resection in the Affiliated Hospital of Xuzhou Medical University were collected. The intra- and post-operative situation and the postoperative complications were analyzed.
Results
The radical resections of hilar cholangiocarcinoma were completed laparoscopically in all the patients. There was no conversion to the laparotomy. The procedure was finished within a time of (231.3±94.5) min and with an intraoperative blood loss of (123.3±46.8) mL. The first postoperative exhausting time and the postoperative hospital stay was (2.7±0.3) d and (11.9±1.7) d, respectively. All the patients had the R0 resection and the numbers of dissected lymph nodes were 9.4±2.7. The postoperative complications occurred in 2 patients, they were all cured spontaneously in one week, and there was no perioperative death. None of patients had a local recurrence and metastasis during an average 8 months of following-up.
Conclusions
Preliminary results of limited cases in this study show that with suitable case and skillful laparoscopic technique, laparoscopic radical resection of hilar cholangiocarcinoma is feasible and safe. Further studies are still needed to confirm benefits of this approach.
ObjectiveTo explore the advantages and disadvantages of preoperative biliary drainage, the timing of preoperative biliary drainage, and the characteristics of various drainage methods for resectable hilar cholangiocarcinoma.MethodsBy reviewing relevant literatures at home and abroad in the past 20 years, the controversies related to the preoperative biliary drainage, surgical biliary drainage, and various drainage methods for resectable hilar cholangiocarcinoma were reviewed.ResultsThere is still a great deal of controversy about whether preoperative bile duct drainage is required for resectable hilar cholangiocarcinoma routinely, but there is a consensus on the timing of preoperative biliary drainage, and various drainage methods have their own characteristics.ConclusionsThe main treatment for hilar cholangiocarcinoma is radical surgical resection, but cholestasis is often caused by malignant biliary obstruction, which makes it difficult to manage perioperatively. A large number of prospective studies are needed to provide more evidence for the need for routine preoperative biliary drainage in patients with hilar cholangiocarcinoma who can undergo resection.
Objective
To compare the clinicopathological features of hilar cholangiocarcinoma (HCCA) and hilar benign diseases, and then explore the value of carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) in the differential diagnosis between them.
Methods
Clinical data of 65 patients (54 patients with HCCA and 11 patients with hilar benign diseases) who were diagnosed as HCCA and received treatment from January 2011 to October 2015 in our hospital were retrospectively analyzed. Comparison of clinical data of HCCA patients and patients with hilar benign diseases in age, gender, disease duration, clinical manifestation, laboratory examination, and imaging examination was performed, and the receiver operating characteristic curve (ROC) was used to explore the value of CA19-9 and CEA in differential diagnosis between hilar benign diseases and HCCA.
Results
The age, levels of serum CA19-9, CEA, alanine aminotransferase (ALT), total bilirubin (BILT), and direct bilirubin (BILD) of HCCA group were significantly higher than that in benign group (P<0.05). However, the gender, disease duration, clinical manifestations (including jaundice, abdominal discomfort, fever, and weight loss), serum aspartate aminotransferase (AST), serum alkaline phosphatase (ALKP), and imaging findings (including hilar mass, intrahepatic bile duct dilatation, thickening of the bile duct wall, lymph node enlargement, vascular invasion, and gallbladder invasion) had no significant difference between the 2 groups (P>0.05). The ROC curve results showed that, when cut-off point for CA19-9 was 233.15 U/mL, the sensitivity was 56% and specificity was 91%; when cut-off point for CEA was 2.98 ng/mL, the sensitivity was 61% and specificity was 90%.
Conclusions
For the differential diagnosis between HCCA and hilar benign diseases, the elderly patients with high levels of serum transaminase and bilirubin were more likely to be malignant. It is more likely to be malignant when the serum CA19-9>233.15 U/mL or CEA>2.98 ng/mL.
ObjectiveTo summarize a patient diagnosed as Bismuth type Ⅲa hilar cholangiocarcinoma who unerwent the curative surgery combined with partial portal vein resection and reconstruction+hilar bile duct formation+Roux-en-Y choledochojejunostomy, meanwhile we reviewed the current status of surgical treatment of hilar cholangiocarcinoma at home and abroad.MethodsTo retrospectively summarized and analyzed the clinical data of one case of Bismuth type Ⅲa hilar cholangiocarcinoma. The preoperative total bilirubin of this patient was 346.8 μmol/L, and this patient underwent the curative surgery combined with partial portal vein resection and reconstruction+hilar bile duct formation+Roux-en-Y choledochojejunostomy after reducing jaundice by percutaneous transhepatic biliary drainage (PTBD). Then we retrieved domestic and foreign related literatures.ResultsOperative time of this patient was about 290 min and intraoperative bleeding was about 350 mL. No intraoperative blood transfusion occurred. The results of pathological examination showed middle-differentiatied adenocarcinoma of hilar bile duct with negative tumor margins and no regional lymph node metastasis (0/14). The postoperative recovery was uneventful with hospital stay time of 9 days and without any complication. The patient had been followed-up in the outpatient department for 3 years,and was generally in good condition. The evidence of recurrence or metastasis wasn’t found.ConclusionsPre-operative biliary drainage can improve the safety of operation and reduce the incidence of postoperative complications, extend liver resection for the patient with Bismuth type Ⅲa hilar cholangiocarcinoma, which can improve R0 resection rate and extend postoperative survival.
Objective
To explore application value of photodynamic therapy (PDT) in treatment of unresectable hilar cholangiocarcinoma.
Method
The literatures about PDT in the treatment of the unresectable hilar cholangiocarcinoma in the PubMed, MedLine, Embase, CNKI, and Wanfang databases were reviewed.
Results
The PDT combined with stent or chemotherapy was the main method in the treatment of the unresectable hilar cholangiocarcinoma, which could make the tumor down-staging, obviously reduce the jaundice, improve the quality of life, improve the survival rate, prolong the stent patency and be treated repeatedly. Especially, it was suitable for the patients with elderly, poor health, intolerance of surgery, could partly replace the R1 or R2 operation of hilar cholangiocarcinoma and avoid the risk of surgery and postoperative complications. The therapeutic effective of the PDT was related to the early therapy and times of therapy. However, the shortcomes of the PDT were that the depth of killing tumor was not enough and there was a certain incidence of adverse reaction.
Conclusions
Therapeutic effect of PDT combine with stent or chemotherapy for unresectable hilar cholangiocarcinoma is better than that of single therapy. It is expected to be a first-line scheme of palliative treatment for unresectable hilar cholangiocarcinoma.
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.
Objective
To explore favorable factors of reducing incidence of postoperative liver failure after radical resection of Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma in condition of hyperbilirubinemia.
Methods
All the clinical data of one patient with Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma underwent radical resection in June 2017 in the West China Hospital of Sichuan University were collected. The preoperative total bilirubin level of this patient was 470.3 μmol/L, the patient didn’t receive preoperative biliary drainage. The preoperative jaundice time and cholangitis were calculated accurately. A 3D imaging system for quantitative evaluation of the liver was used to reconstruct the images with contrast-enhanced CT images of this patient. And the total liver volume and the future liver remnant volume (FLRV) were calculated. Finally, 6 months of follow-up were conducted after surgery.
Results
The exact jaundice time was 20 d and there was no preoperative cholangitis. The postoperative FLRV accounted for about 70%. No postoperative liver failure occurred. No recurrence of tumor and death of patient occurred after 6 months of follow-up.
Conclusions
Radical resection of hilar cholangiocarcinoma in condition of hyperbilirubinemia is not an absolute contraindication for surgery, but indications should be strictly controlled. For special patient whose jaundice with short duration, no preoperative cholangitis and a high FLRV may be treated with directly radical surgery to prevent for losting the best time of surgery.
At present, the application of extended radical surgery in hilar cholangiocarcinoma (hCCA) remained controversial. The author reviewed the relevant literatures published in recent years and combined with his own experience, preliminarily discussed the application value of extended radical surgery in hCCA, and believed that: for some strictly selected cases of hCCA, under the premise of ensuring patient safety, extended radical surgery was an important treatment method for hCCA patients to obtain R0 removal, and the survival status of patients was better than that of palliative surgery, but the indications need to be strictly mastered. For patients with hCCA, whether to adopt extended radical surgery and the specific scope of surgical resection should be based on the scope of lesions and the involved organs, tissues and blood vessels to implement an individualized surgical program on the premise of comprehensive evaluation and full preparation before surgery. Do not blindly carry out extended radical surgery.
Objective
To summarize the progress in diagnosis and treatment of hilar cholangiocarcinoma at present.
Methods
The literatures about diagnosis and treatment of hilar cholangiocarcinoma at home and aboard were collected to make an review.
Results
The diagnosis of hilar cholangiocarcinoma mainly depended on serum tumor molecular markers and imaging examinations. Preoperative excision and prognostic evaluation were required, including tumor classification and staging, preoperative yellow reduction, residual liver volume assessment, and so on. Radical resection was the first choice, as well as liver transplantation, radiotherapy, chemotherapy, and photodynamic therapy could be selected according to the patient’s condition.
Conclusions
The appearance of new diagnosis and treatment technology promotes the clinical development of hilar cholangiocarcinoma. The integrated diagnosis and treatment mode, which is based on surgery, will become the inevitable direction of the development of hilar cholangiocarcinoma.
