ObjectiveTo explore the treatment and prognostic factors of typeⅢhilar cholangiocarcinoma. MethodsThe data of 170 cases of typeⅢhilar cholangiocarcinoma treated in our hospital from Jan. 2002 to Dec. 2011 were retrospectively analyzed. ResultsAmong these 170 patients of typeⅢhilar cholangiocarcinoma, 109 patients underwent surgical exploration in which 60 patients underwent resection and the remaining 49 patients were found unresectable and underwent U-tube or metallic stent drainage. Sixty one patients were preoperatively assessed as unresectable in which 14 patients underwent percutaneous transhepatic cholangial drainage and the remaining 47 patients refused any surgical intervention. Results of Cox proportional hazard model showed that residual tumor status (HR=4.621, 95% CI:1.907-11.199, P=0.001), lymph node metastasis (HR=2.792, 95% CI:1.393-5.598, P=0.004), and hepatectomy (HR=3.003, 95% CI:1.373-6.569, P=0.006) were independent prognostic factors which associated with patients in resection group. Besides, treatmentR0 resection (HR=0.177, 95% CI:0.081-0.035, P < 0.001), no treatment (HR=5.568, 95% CI:2.733-11.342, P < 0.001)] and vascular invasion (HR=1.667, 95% CI:1.152-2.412, P=0.007) were prognostic factors associated with all patients. ConclusionsTreatment and vascular invasion are the most important predictors of prolonging survival associated with typeⅢhilar cholangiocarcinoma. Besides, R0 resection including hepatectomy without lymph nodes metastasis is feasible in the majority of patients with resectable hilar cholangiocarcinoma.
ObjectiveTo investigate the value of diffusion weighted imaging (DWI) combined with three-dimensional volumetric interpolated breath-hold examination (3D-VIBE) in evaluating metastatic lymph nodes secondary to hilar cholangiocarcinoma. MethodsFrom July 2009 to March 2011, DWI examination was performed in 37 patients with hilar cholangiocarcinoma, which was compared with 3D-VIBE sequences. The morphological characteristics and distribution were analyzed for metastatic and nonmetastatic lymph nodes. Signal intensity (SI) was measured on DWI images and apparent diffusion coefficient (ADC) was calculated for each lymph node. The SI of lymph nodes (SILN） and liver (SIliver) were also measured and the ratio of SI was calculated. The ADC and the ratio of SI were compared between metastatic and nonmetastatic lymph nodes. ResultsThere were fifty-nine groups of lymph nodes in 37 patients with hilar cholangiocarcinoma, fifty-one groups were revealed in both DWI and 3D-VIBE sequences, and eight groups were only demonstrated in one sequence (P=0.070). The short diameters were (1.05±0.42) cm and (0.78±0.22) cm on 3D-VIBE images for metastatic and nonmetastatic lymph nodes, respectively (P=0.030). The ADC value in metastatic lymph nodes was (1.64±0.3)×10-3 mm2/s, which was significantly lower than that in nonmetastatic lymph nodes 〔(2.28±0.79)×10-3 mm2/s〕 on DWI images (P=0.033). There were no significant differences in SILN/SIliver between metastatic and nonmetastatic lymph nodes on images of portal venous phase and 3 min delayed contrast-enhanced phase. ConclusionsDifferences of ADC and short diameter can provide valuable information to differentiate metastatic lymph nodes with nonmetastatic lymph nodes. When combined with 3D-VIBE sequence, DWI is more effective in evaluating metastatic lymph nodes secondary to hilar cholangiocarcinoma.

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.
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.
【Abstract】ObjectiveTo report the diagnosis and treatment of hilar cholangiocarcinoma.MethodsThe relevant information about the hispathological feature, transfer ways, clinical manifestation, laboratory examination, imaging feature, immunohistochemical examination and treatment ways were gathered from previous original articles, and checking the latest issues of appropriate journals.ResultsThe clinical manifestation, laboratory examination, and imaging feature of hilar cholangiocarcinoma were due to the neoplasm obstructing bile duct and sequent infection of bile duct. The diagnosis was depanded on the combining clinical manifestation, laboratory examination and imaging feature. The value of immunohistochemical examination was not clear. Radical surgery was the best treatment of unique curing the neoplasm. By-pass surgery was used in the late phase patients to solve the obstruction of bile and digest duct. The effect of unique chemical treatment was not perfect. It did’t generally propose the treatment of orthotopic liver transplantation.ConclusionThe perfect prognosis of hilar cholangiocarcinoma is depended on early diagnosis and redical surgery.
ObjectiveTo discuss the treatment methods and outcome of hilar cholangiocarcinoma. MethodsFrom January 2002 to December 2008, 81 cases of hilar cholangiocarcinoma were retrospectively analyzed. ResultsAmong 81 patients, there were 55 males and 26 females, ages were from 38 to 72 years with an average age 57.5 years. In BismuthCorlette classification, 5 cases were type Ⅰ, 15 cases type Ⅱ, 14 cases type Ⅲa, 14 cases type Ⅲb, 33 cases type Ⅳ, according to the preoperative results of MRCP, but the classification of 15 cases were not consistent to the preoperative results (5 cases type Ⅱ, 8 cases type Ⅲ, 2 cases type Ⅳ) according to the results of intraoperative exploration. The rates of complications of radical operation, palliative operation, internal biliary drainage, and external biliary drainage were 54.5%(12/22), 58.8%(10/17), 23.8%(5/21), and 66.7%(14/21), respectively. The rate of complications of internal biliary drainage was lower than that of the other three methods (Plt;0.01), there were no significant differences among the other three methods. The 1, 2, 3, and 5year survival rates of 22 patients with radical operation, 17 patients with palliative operation, 21 patients with internal biliary drainage, 21 patients with external biliary drainage were 75.0%, 60.0%, 38.3%, 2.6%; 72.7%, 26.5%, 4.2%, 0; 50.5%, 15.8%, 2.2%, 0; 30.6%, 8.5%, 0, 0, respectively. The median survival time was 29.5 months, 13.8 months, 10.5 months, and 8.3 months, respectively. Survival rate of radical operation was higher than that of palliative operation (χ2=14.20, P=0.000 3), palliative operation was higher than that of internal biliary drainage (χ2=4.50, P=0.040 5), and internal biliary drainage was higher than that of external biliary drainage (χ2=4.45, P=0.040 1). ConclusionsThe BismuthCorlette classification is a guide to the required surgery, but the results of intraoperative exploration decides the final classification and operative method. Radical resection is the main related factors influencing the therapy efficacy of hilar cholangiocarcinona. Basinstyle anastomosis and T type supportingtube is the first choice of palliative operation. External drainage, to the full, is avoided.
Objective To discuss the relationship between the efficiency of bile duct drainage and the postoperative liver functional recovery and the prognosis of hilar cholangiocarcinoma. Methods We studied retrospectively 58 cases of hilar cholangiocarcinoma which entered our department between June 1987 and October 1998. The postoperative liver functional recovery and mortality and morbidity between unilateral (n＝27) and bilateral (n＝31) bile duct drainage groups were compared. Results The liver function in bilateral drainage group was nearly normal within 6 weeks after operation. The ALb level of unilateral drainaged patients recovered gradually to normal after operation, and the TBIL and ALT decrease nearly to the normal range within 6 weeks after operation. The AKP decreased within 2 postoperative weeks, then steadily increased. The differences of perioperative complication rate and mortality of the two groups showed no significance. Conclusion The data showed that the liver function can recover to some extent by unilateral bile duct drainage, and unilateral drainage operations are the choice for hilar cholangiocarcinoma that can not be excised now.
