ABSTRACT

Objective:To investigate the value of three-dimensional reconstruction combined with serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) detection in the diagnosis and resectability evaluation of hilar cholangiocarcinoma (HCCA) before resectable lymph node metastasis.Methods:A total of 65 patients with suspected HCCA who were treated at Yiwu Central Hospital from June 2019 to June 2022 were included in the observation group. Thirty healthy people who concurrently underwent physical examinations in the same hospital were included in the control group. All participants underwent a CT three-dimensional reconstruction examination. Simultaneously, the automatic electrochemiluminescence immunoassay analyzer was used to measure serum levels of CA19-9 and CEA. The outcomes of percutaneous transhepatic cholangiography were used as the "gold standard". The consistency between CT three-dimensional reconstruction, CA19-9 detection, and CEA detection, either individually or combined, and the "gold standard" in the diagnosis of HCCA was evaluated.Results:Serum levels of CA19-9 and CEA in the observation group were (62.71 ± 10.63) U/mL and (62.71 ± 10.63) ng/mL, respectively, which were significantly higher than those in the control group [(12.37 ± 7.39) U/mL, (1.31 ± 0.97) ng/mL, t = 23.43, 11.59, both P < 0.05). The levels of CA19-9 [(71.69 ± 12.37) U/mL] and CEA [(8.89 ± 3.51) ng/mL] in patients with HCCA who had lymph node metastasis were significantly higher than those in patients with HCCA who had no lymph node metastasis [CA19-9 (56.78 ± 10.16) U/mL, CEA (6.45 ± 2.11) ng/mL, t = 4.14, 2.76, both P < 0.05].Compared with histopathological examination, the accuracy of CT three-dimensional reconstruction in typing was 85.00%. According to the "gold standard" diagnosis, CT three-dimensional reconstruction, CA19-9 detection, and CEA detection, alone and their combination, successfully detected HCCA in 22 cases (55.00%), 26 cases (65.00%), 31 cases (77.50%), and 38 cases (95.00%), respectively. The detection rate of HCCA was the highest when CT three-dimensional reconstruction, CA19-9 detection, and CEA detection were combined, and the difference was statistically significant ( χ2 = 18.15, P < 0.05). Compared with CT three-dimensional reconstruction (AUC: 0.808), CA19-9 detection (AUC: 0.721), and CEA detection (AUC: 0.703) individually, their combination (AUC: 0.913) had the highest value in the diagnosis of HCCA (all P < 0.05). Conclusion:CT three-dimensional reconstruction, CA19-9 detection, and CEA detection have a certain diagnostic value for HCCA, but the combination of CT three-dimensional reconstruction with the detection of serum levels of CA19-9 and CEA has a higher diagnostic value for HCCA, providing an effective reference for the preoperative evaluation of the resectability of HCCA in the clinic.

ABSTRACT

ObjectiveTo investigate the difference in the level of biliary calprotectin between patients with cholangiocarcinoma and those with choledocholithiasis. MethodsClinical data and bile samples were collected from 34 patients with cholangiocarcinoma and 78 patients with choledocholithiasis who were diagnosed and treated with endoscopic retrograde cholangiopancreatography in The First Affiliated Hospital of Anhui Medical University from May 2021 to September 2022. Fluorescence lateral flow immunoassay was used to measure the levels of calprotectin, hemoglobin, and lactoferrin in bile. The Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; the Spearman correlation test was used for correlation analysis; the DeLong test was used for comparison of the area under the ROC curve (AUC). ResultsCompared with the choledocholithiasis group, the cholangiocarcinoma group had significant increases in the levels of calprotectin [4 795.50 (2 286.79‍ ‍—‍ ‍20 179.73) ng/mL vs 411.16 (67.03‍ ‍—‍ ‍1 991.88) ng/mL, Z=5.572, P<0.001] and fluoride [115.70 (109.10‍ — ‍125.50) mmol/L vs 106.60 (98.60‍ ‍—‍ ‍114.40) mmol/L, Z=2.702, P=0.007]. The patients with cholangiocarcinoma were further divided into high cholangiocarcinoma group and low cholangiocarcinoma group, and there was no significant difference between the two groups in the level of calprotectin [3 867.71 (2 235.66‍ — ‍26 407.40) ng/mL vs 4 795.50 (2 361.15‍ — ‍13 070.53) ng/mL, Z=0.129, P>0.05]. Biliary calprotectin level was correlated with white blood cell count, hemoglobin concentration, and lactoferrin concentration in bile (r=0.316, 0.353, and 0.464, all P<0.05). The ROC curve analysis showed that biliary calprotectin (with a sensitivity of 79.4% and a specificity of 75.6%), blood CA19-9 (with a sensitivity of 82.4% and a specificity of 78.2%), and their combination (with a sensitivity of 88.2% and a specificity of 73.1%) had good sensitivity and specificity in the diagnosis of cholangiocarcinoma. ConclusionThere is an increase in the level of biliary calprotectin in patients with cholangiocarcinoma, and therefore, it might become a biomarker for the diagnosis of cholangiocarcinoma.

ABSTRACT

Cholangiocarcinoma (CCA) is a highly malignant biliary tumor with strong invasion and poor prognosis and is insensitive to radiotherapy and chemotherapy. Tumor-associated macrophage (TAM) is an important component of the tumor microenvironment. CCA cells recruit TAM into tumor tissue by releasing cytokines and polarize them into M2 TAM, which promotes the progression of CCA through various mechanisms such as assisting immune escape, promoting tumor cell proliferation, regulating angiogenesis, promoting tumor metastasis, and mediating immune resistance. As an emerging target of tumor immunotherapy, TAM provides new ideas for targeted therapy for CCA. This article reviews the mechanisms of TAM in promoting the progression of CCA and immunotherapy targeting TAM in recent years.

ABSTRACT

Objective:To evaluate the predictive value of prognostic nutritional index (PNI) for survival after radical resection in patients with distal cholangiocarcinoma.Methods:The clinical data of 160 patients with distal cholangiocarcinoma undergoing radical pancreatoduodenectomy in Beijing Chaoyang Hospital Affiliated to Capital Medical University from September 2011 to March 2022 were retrospectively analyzed, including 97 males and 63 females, aged (65.58±9.22) years old. The optimal cut-off value of PNI for predicting postoperative survival was 42.275 determined by the receiver operating characteristic curve. Patients were divided into the low PNI group ( n=79, PNI<42.275) and high PNI group ( n=81, PNI≥42.275). The survival status of patients were followed up by outpatient clinic or telephone review. Survival analysis was performed using the Kaplan-Meier method and the log-rank test. Factors with P<0.1 in the univariate analysis were included in the Cox proportional hazards model for multivariate analysis to screen the prognostic factors. Results:There were statistically significant differences in the preoperative albumin, total bilirubin, lymphocytes counts between the two group (all P<0.05). The postoperative median survival time of the low PNI group was 17 months, with cumulative 1, 3 and 5-year survival rates of 62.0%, 25.0% and 16.2%, respectively. The postoperative median survival time of the high PNI group was 23 months, with cumulative 1, 3 and 5-year survival rates of 84.0%, 46.4% and 40.4%, respectively. There was a significant difference between the two groups ( P<0.001). PNI score<42.275 ( HR=1.040, 95% CI: 1.011-1.071, P=0.008), CA19-9>37 U/ml ( HR=1.620, 95% CI: 1.046-2.509, P=0.031), venous invasion ( HR=1.809, 95% CI: 1.013-3.230, P=0.045), lymph node metastasis ( HR=1.956, 95% CI: 1.300-2.969, P=0.001), tumor diameter >2 cm ( HR=1.534, 95% CI: 1.011-2.328, P=0.044), without postoperative adjuvant chemotherapy ( HR=2.828, 95% CI: 1.291-6.195, P=0.009) had a greater risk of poor survival after radical resection. Conclusion:PNI score could be an influencing factor and serve as a predicting tool for the survival after radical resection in patients with distal cholangiocarci-noma.

ABSTRACT

Objective:To evaluate the efficacy of endoscopic stenting drainage for patients with malignant hilar biliary obstruction caused by unresectable hepatocellular carcinoma.Methods:Data of 106 patients with malignant hilar obstruction caused by unresectable hepatocellular carcinoma who received endoscopic stenting drainage in the Third Affiliated Hospital of Naval Medical University from January 2012 to January 2019 were retrospectively analyzed. According to the different stent types, they were divided into the metal stent group (30 cases) and the plastic stent group (76 cases). The observation indexes included clinical success rate, complication incidence, stent patency and overall survival time. The independent predictors for stent patency and overall survival of patients were analyzed by multivariate Cox regression model.Results:The overall clinical success rate was 67.9% (72/106) and the incidence of postoperative cholangitis was 29.2% (31/106). The clinical success rates were 93.3% (28/30) and 57.9% (44/76) ( χ2=12.40, P<0.001), and the incidences of postoperative cholangitis were 13.3% (4/30) and 35.5% (27/76) ( χ2=5.12, P=0.024) in the metal stent group and the plastic stent group, respectively. The median stent patency was 5.2 (95% CI:3.7-6.0) months, and the overall survival time was 3.0 (95% CI:2.5-3.7) months. Multivariate Cox regression analysis showed that hepatic drainage volume <30% was an independent predictor for stent patency ( HR=2.12, 95% CI:1.01-4.46, P=0.048). Bismuth type Ⅳ ( HR=2.06, 95% CI:1.12-3.77, P=0.020), Child-Pugh class C ( HR=4.09, 95% CI: 2.00-8.39, P<0.001) and plastic stent ( HR=1.87, 95% CI:1.21-2.90, P=0.005) were independent predictors for overall survival time. Conclusion:Hepatocellular carcinoma involving the hilar bile duct has a poor prognosis. Compared with plastic stents, metal stents show advantages in clinical success rate and incidence of postoperative cholangitis. Hepatic drainage volume <30% is an independent predictor for stent patency, and Bismuth type Ⅳ, Child-Pugh class C and plastic stent are independent predictors for overall survival time.

ABSTRACT

Objective:To explore the expression level and clinicopathological characteristics of 14-3-3θ protein in distal cholangiocarcinoma tissues, and further analyze the long-term prognosis of patients with different expression levels.Methods:A retrospective cohort study was conducted to collect and analyze the clinical data of 135 patients with distal cholangiocarcinoma who underwent surgical resection at the Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2015 to December 2021, including 86 males and 49 females.(65.1±10.1) years old. Immunohistochemistry was used to detect the expression level of 14-3-3θ protein in cholangiocarcinoma tissue. The postoperative pathological sections of patients were evaluated based on the immune response score(IRS). The optimal cutoff value was determined through the receiver operating characteristic(ROC) curve was 3.5. Currently, the area under the curve was 0.741, the sensitivity was 73.5%, and the specificity was 71.3%. The patients were divided into two groups: IRS<4 was the 14-3-3θ low expression group( n=81), IRS≥4 was the 14-3-3θ high expression group( n=54). After surgery, the patient′s survival status was followed up through a combination of outpatient review and telephone follow-up. Normally distributed measurement data were expressed as mean ± standard deviation( ± s), and comparisons between groups were made using the t test; non-normally distributed measurement data were expressed as M( Q1, Q3), and comparisons between groups were made using the rank sum test. The chi-square test was used to compare enumeration data between groups. Results:The preoperative CA19-9 and lymph node metastasis in the 14-3-3θ low expression group were 44.3(20.8, 132.2) U/mL and 28 cases respectively. The preoperative CA19-9 and lymph node metastasis in the 14-3-3θ high expression group were 82.3(43.4, 396.9) U/mL and 32 cases respectively. The difference between the two groups was statistically significant( P<0.05). All patients had regular postoperative telephone calls or return to the hospital for follow-up. The median postoperative survival time of the 14-3-3θ low-expression group was 36 months. The 1-, 2-, and 3-year survival rates after surgery were 88.9%, 66.5%, and 66.5%, respectively. 49.4%, the median survival time after surgery in the 14-3-3θ high expression group was 13 months, and the 1, 2, and 3-year survival rates after surgery were 53.7%, 23.3%, and 13.3% respectively. The difference between the two groups was statistically significant. significance( P<0.01). Cox proportional hazard model performed multivariate analysis, CA19-9>37 U/mL ( RR=1.970, 95% CI: 1.186-3.272, P=0.009), lymph node metastasis( RR=1.681, 95% CI: 1.035-2.729, P=0.036) and 14-3-3θ staining intensity≥4 ( RR=2.438, 95% CI: 1.546-3.845, P<0.001) have worse long-term prognosis. Conclusions:The expression level of 14-3-3θ protein is related to CA19-9 and lymph node metastasis in distal cholangiocarcinoma. A high expression of 14-3-3θ protein indicates poor long-term prognosis in patients with extrahepatic cholangiocarcinoma.

ABSTRACT

Fibroblast growth factor receptor (FGFR) 2 gene fusion plays an important role in the pathogenesis of cholangiocarcinoma (CCA) . The method of targeting FGFR2 has been listed as the major therapy for advanced CCA. Adenosine triphosphate (ATP) -competitive FGFR inhibitors, represented by infigratinib and pemigatinib, effectively delay tumor progression and prolong patients survival, and are the first-line drugs for advanced CCA patients with FGFR2 fusion. However, almost all the patients treated with infigratinib eventually develop resistance, which require the combination with other drugs. Futibatinib may serve as a later-line drug for advanced CCA patients with V564F mutation after infigratinib resistance. For the infigratinib-resistant CCA patients harboring aberrant activation of the mitogen-activated protein kinase (MAPK) pathway, combination of the MAPK inhibitor or the heat shock protein 90 inhibitor may be considered as a novel therapeutic option.

ABSTRACT

At present, surgical treatment is the most effective method for the treatment of hepatobiliary malignant tumor. However, due to the complex anatomical structure of hepatobiliary region, accompanied by vascular variation, and with the continuous update of medical concepts, the requirements for surgery are more strict. Traditional imaging examination has reached a bottleneck in the support of surgical treatment, while 3D printing technology is compared with the former. It showed strong advantages in preoperative program planning and improving the effect of intraoperative precise resection. At the same time, it also shows great potential for medical assistance and disease treatment in the production of bioactive models, and 3D printing technology has obviously enhanced the understanding of surgery for young doctors, and medical staff can create a variety of highly practical 3D printing models under the existing conditions. In the future, it is expected to overcome the limitations of materials and technology and bring higher therapeutic benefits for the majority of patients.

ABSTRACT

The incidence of intrahepatic cholangiocarcinoma has been increasing worldwide in recent years. Hepatectomy is the first choice for surgical treatment of intrahepatic cholangiocarcinoma. However, due to high tumor invasion, early lymph node metastasis and other factors, only less than 30% of cases are resectable, and the overall prognosis of patients is very poor. Theoretically, liver transplantation can not only remove the tumor, but also replace the damaged liver. Therefore, many scholars have proposed liver transplantation for the treatment of intrahepatic cholangiocarcinoma in order to obtain better results. Intrahepatic cholangiocarcinoma was once listed as a contraindication of liver transplantation due to limited cases, tumor recurrence, and shortage of donors. However, with the optimization of recipient screening criteria and the development of neoadjuvant therapy, part of patients can also benefit from it, making liver transplantation a potential therapeutic strategy. Based on the literature review and the author′s experience, this article introduced the current situation of surgical treatment of intrahepatic cholangiocarcinoma, the comparison between hepatectomy and liver transplantation, the latest progress of liver transplantation treatment and the future challenges and solutions.

ABSTRACT

Hilar cholangiocarcinoma(HCCA) is a relatively rare disease with great invasiveness. Traditionally, radical resection has been considered the cornerstone of its treatment. However, only less than 40% of cases can be resected. Surgical resection is complex, risky and difficult to achieve R0 resection and may lead to various postoperative complications. In recent years, the combination of neoadjuvant chemoradiotherapy with liver transplantation(LT) has provided an option for patients with unresectable diseases, and strict patient screening criteria has allowed LT protocol to achieve promising therapeutic effects in PCCA. In order to provide an intellectual background for the choice of LT protocol in the clinical treatment of HCCA patients, this article will review the application standards of LT in HCCA, summarize the application status of LT in patients with different resectability, compare the prognostic effect of resection and LT, and introduce the advantages of LT in the treatment of HCCA associated with primary sclerosing cholangitis(PSC).

ABSTRACT

Cholangiocarcinoma is the second most common malignant tumor in primary liver tumors, which has high malignant degree and poor prognosis. At present, there is no satisfactory and effective treatment method. Exosomes from various cells carry a variety of substances and act on the receptor cells, transmitting biological messages between different cells to regulate a variety of physiological and pathological changes. Exosomes can affect the tumor microenvironment and further mediate the tumorigenesis and progression of tumors via multiple approaches. Increasing studies have demonstrated that the non-coding RNA (ncRNAs) carried by tumor-derived exosomes is involved in regulating the occurrence, development and metastasis of cholangiocarcinoma. Combined with the current research progress, this article summarizes the role, diagnosis and treatment value of exosome ncRNAs in cholangiocarcinoma, so as to provide references for follow-up research.

ABSTRACT

Objective:To compare the effectiveness and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for intrahepatic cholangiocarcinoma(ICC).Methods:PubMed, Web of Science, Embase, Cochrane Library, China Biology Medicine Disc, China National Knowledge Infrastructure, Wanfang Database and VIP Database were searched from inception of these databases to May 2022 to compare LH versus OH for ICC. The duration of operation, intraoperative bleeding, proportion of patients with intraoperative blood transfusion, number of resected lymph nodes, proportion of patients with R 0 resection margin, duration of hepatic occlusion, hospital stay, incidence of postoperative complication and postoperative mortality were compared between the two groups. Meta-analysis was carried out using the Review Manager 5.1 software, and the mean difference ( MD) or odds ratio ( OR) was used as the effect index. Results:This meta-analysis included twelve articles, all of which were retrospective cohort studies, with 3 189 patients. There were 667 patients in the LH group and 2 512 in the OH group. Meta-analysis showed that when compared to the OH group, the LH group had significantly less intraoperative bleeding ( MD=-116.06, 95% CI: -173.07--59.06, P<0.001), less proportion of patients receiving intraoperative blood transfusion ( OR=0.25, 95% CI: 0.10-0.62, P=0.003), less number of lymph nodes removed ( MD=-101.91, 95% CI: -124.78--79.03, P<0.001), less patients underwent portal occlusion ( OR=0.37, 95% CI: 0.14 - 0.99, P=0.050), shorter hospital stay ( MD=-2.43, 95% CI: -4.59--0.28, P=0.030) and less postoperative complications ( OR=0.41, 95% CI: 0.28-0.61, P<0.001). However, the proportion of patients with R 0 margin ( OR=1.49, 95% CI: 1.14-1.95, P=0.003) in the LH group was significantly higher than the OH group. There were no significant differences in operative time and postoperative mortality between the 2 groups. Conclusion:LH was more effective and safe than OH in the treatment of ICC. However, its long-term effect still needs to be verified by large randomized controlled trials.

ABSTRACT

Objective:To study the features of adenomyomatous hyperplasia (AH) of the Vaterian system (common bile duct and ampulla of Vater) to help in the diagnosis and management of this disease.Methods:A retrospective analysis on the data of 17 patients who had a postoperative pathological diagnosis of AH of the Vaterian system treated from January 2005 to December 2021 at the First Medical Center of the PLA General Hospital was carried out with 12 males and 5 females, aged (58.4±11.3) years. The clinical presentations, treatment and postoperative pathology of these patients were analyzed. Patients with dysplasia of the tubular mucosal epithelium in the non-cancerous area around the AH under microscopy were included in the AH with dysplasia group ( n=8), and those without dysplasia were included in the control group ( n=9). The clinical characteristics of the two groups were compared. Results:The main clinical symptoms were abdominal pain in 8 patients, jaundice in 7 patients and fever in 2 patients. Preoperative imaging showed 10 cases of occupying lesions and 6 cases of abnormally dilated intrahepatic and extrahepatic bile ducts without obvious lesions or stones or biliary tract injury stenosis. Sixteen patients underwent radical pancreaticoduodenectomy, and 1 patient underwent extrahepatic biliary resection combined with choledochojejunostomy for bile duct obstruction due to biliary stones, 3 patients had combined malignant tumors, 1 patient had a carcinoma of AH origin at the ampulla of Vater, and the other 2 patients had neoplastic lesions in the mucosal epithelium adjacent to the AH (cholangiocarcinoma and ampullary carcinoma, respectively). There were no significant differences in age, gender, bile duct stones, cholangitis, combined carcinoma and liver function indexes between the two groups of patients with AH of the Vaterian system (all P>0.05). Conclusion:Adenomyomatous hyperplasia of the Vaterian system was difficult to distinguish preoperatively from malignant tumors basing on its clinical presentations or imaging findings. Such patients are recommended to be treated surgically.

ABSTRACT

Intrahepatic cholangiocarcinoma (ICC) refers to adenocarcinoma originating from the secondary bile ducts and their branches within the liver, with high malignancy and poor prognosis. Radical surgical resection is currently the only possible way to cure ICC, but only some patients meet the surgical standards, and even with surgical resection, about 60% of patients will relapse within 1~2 years. Neoadjuvant therapy and adjuvant therapy are important perioperative treatment methods for ICC, with the aim of reducing postoperative recurrence and improving postoperative survival. This article aims to elaborate on the current status and research progress of neoadjuvant therapy and adjuvant therapy for ICC.

ABSTRACT

The concept of enhanced recovery after surgery has been widely accepted and applied by clinical medical staff, and has made good progress in the field of hepatobiliary pancreatic surgery in recent years. Hilar cholangiocarcinoma is one of the more complicated operations in hepatobiliary pancreatic surgery. The traditional perioperative management mode is not conducive to the early rehabilitation of patients, and the relative operation risk and the probability of postoperative complications are high. In order to promote the application of enhanced recovery after surgery in patients with hilar cholangiocarcinoma after operation, this paper systematically introduces the measures and experience of accelerated rehabilitation after operation of hilar cholangiocarcinoma from the aspects of postoperative multimodal analgesia, early activity, diet, drainage tube management, discharge and follow-up, based on the relevant literature and combined with own work experience. These measures can reduce the postoperative complications of patients with hilar cholangiocarcinoma and promote their early rehabilitation.

ABSTRACT

Intrahepatic cholangiocarcinoma is a primary hepatic malignant tumor with high malignancy and poor prognosis. In addition to surgical resection, there are no clear studies showing that there are other effective treatments. In recent years, with the deepening of the research on the immune mechanism of various malignant tumors, immunotherapy has been gradually attached importance to various anti-solid tumor treatments, and has also become an important direction in the treatment of intrahepatic cholangiocarcinoma. The important role of tumor microenvironment in the immunotherapy of malignant tumors is gradually recognized. In this paper, the characteristics of immune microenvironment in intrahepatic cholangiocarcinoma has been summarized, and the application of immunotherapy in intrahepatic cholangiocarcinoma has been reviewed, with emphasis on the development of immune checkpoint inhibitors, cancer vaccines and adoptive cellular immunotherapy.

ABSTRACT

Objective:To investigate the risk factors for textbook outcomes (TO) of intra-hepatic cholangiocarcinoma (ICC) after hepatectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 155 ICC patients who underwent hepatectomy in the First Affiliated Hospital of Sun Yat-sen University from September 2014 to August 2019 were collected. There were 90 males and 65 females, aged 60(range, 26?82)years. Observation indicators: (1) treatment situations; (2) TO situations; (3) analysis of risk factors for postoperative TO. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative sur-vival of patients up to October 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent samples t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test, Yates' calibration chi-square test or Fisher exact probability. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-rank test was used for survival analysis. The univariate analysis was conducted using the corresponding statistical methods based on data type. The Logistic regression model was used for multivariate analysis. The receiver operating characteristic (ROC) curve was used for evaluating the diagnostic value of indicators (the optimal cut-off value). Results:(1) Treatment situations. Of the 155 patients, 46 cases underwent minor hepatectomy and 109 cases underwent major hepatectomy. Twenty-one of the 155 patients underwent combined bile duct reconstruction. Ninety-five of the 155 patients underwent lymph node dissection, including 41 cases with positive lymph node by postoperative histopathological examinations. The operation time and volume of intraoperative blood loss of the 155 patients were 250.0(range, 95.0?720.0)minutes and 300.0(range, 50.0?15 000.0)mL, respectively. The optimal cut-off values of the operation time and volume of intraoperative blood loss for TO calculated by ROC curve were 247.5 minutes and 325.0 mL, respectively. Of the 155 patients, 44 cases received intraoperative blood transfusion and 10 cases received postoperative blood transfusion (5 cases with intraoperative and postoperative blood transfusion). Seventy-four of the 155 patients had postoperative complications, including 39 cases with mild complications and 35 cases with serious complications. The total duration of hospital stay of the 155 patients was 19 (range, 8?77)days. (2) TO situations. Of the 155 patients, 150 cases achieved R 0 resection, 120 cases had no major postoperative complications, 106 cases had no perioperative blood transfusion, 79 cases had no prolonged duration of hospital stay, 152 cases had no death within postoperative 30 days and 150 cases had no readmission within 30 days after discharge. Of the 155 patients, 56 cases achieved postoperative TO, while 99 patients did not achieve TO. (3) Analysis of risk factors for postoperative TO. Results of univariate analysis showed that preoperative biliary drainage, preoperative Child-Pugh grading of liver function, preoperative asymp-tomatic leukocytosis, preoperative total bilirubin, preoperative alkaline phosphatase, preoperative CA19-9, preoperative CA125, operation time, volume of intraoperative blood loss, tumor diameter, pathological T staging and pathological N staging were related factors for preoperative TO of ICC patients undergoing hepatectomy ( χ2=4.31, 4.31, 4.38, 4.80, Z=?4.15, χ2=10.74, 15.44, 16.59, 27.53, 6.53, 6.77, 9.26, P<0.05). Bile duct reconstruction was also a related factor for postoperative TO of ICC patients ( P<0.05). Results of multivariate analysis showed that preoperative biliary drainage, preoperative asymptomatic leukocytosis, preoperative CA19-9 >35 U/mL, preoperative CA125 >35 U/mL and volume of intraoperative blood loss >325.0 mL were independent risk factors for postoperative TO of ICC patients undergoing hepatectomy ( odds ratio=74.77, 11.73, 2.40,4.86, 6.42, 95% confidence intervals as 1.80?113.39, 1.19?115.54, 1.04?5.53, 1.78?13.26, 2.41?17.11, P<0.05). Conclusions:Preoperative biliary drainage, preoperative asymptomatic leukocytosis, preoperative CA19-9 >35 U/mL, preoperative CA125 >35 U/mL and volume of intraoperative blood loss >325.0 mL are independent risk factors for postoperative TO of ICC patients undergoing hepatectomy.
