Abstract
This study evaluated the prevalence and risk factors of early- (within 7 days of placement) and late-onset (after 7 days of placement) cholecystitis after Y-configured metal stent placement. Between June 2005 and August 2020, 109 patients who had been treated with Y-configured metal stents for malignant hilar obstruction were enrolled in the study. We retrospectively analyzed the potential risk factors for post-stent cholecystitis. The presence of diabetes (p = 0.042), the length of the common part of the Y-stent (p = 0.017), filling of the gallbladder with contrast medium during the procedure (p = 0.040), and tumor invasion of the cystic duct accompanied by filling the gallbladder with contrast medium during metal stent placement (p = 0.001) were identified as important risk factors. In cases of late-onset cholecystitis, stent obstruction (p = 0.004) and repeated endoscopic procedures due to stent malfunction (p = 0.024) were significant risk factors. In the multivariate logistic regression analysis, significant risk factors were the length of the common part of the Y-stent (p = 0.032) in early-onset cholecystitis and stent obstruction (p = 0.007) in late-onset cholecystitis. This study demonstrated that early-onset cholecystitis may occur in patients according to the length of the common portion of the Y-stent. In contrast, late-onset cholecystitis may occur in patients with stent obstruction.

Abstract
OBJECTIVE To investigate the application value of combined intravenous contrast-enhanced ultrasound (IV-CEUS) with intrabiliary contrast-enhanced ultrasound (IB-CEUS) in the preoperative evaluation of hilar cholangiocarcinoma (HCCA) resectability. METHODS Clinical data from 82 patients with HCCA confirmed by surgery and pathology were retrospectively analyzed. Preoperative IV-CEUS + IB-CEUS and magnetic resonance cholangiopancreatography (MRCP) were performed and the results were compared with surgical and pathological findings. RESULTS The accuracy of the Bismuth-Corlette classification confirmed by IV-CEUS + IB-CEUS and MRCP was 95.12% (78/82) and 87.8% (72/82), respectively. The diagnostic precision of IV-CEUS + IB-CEUS was better than MRCP (p = 0.001). The sensitivity, specificity, and precision of CEUS for diagnosing lymph node metastases (72.7%, 93.3%, and 87.8%), intrahepatic metastases (78.6%, 98.5%, and 93.9%), invasion of the hepatic artery (92.9%, 98.5%, and 97.6%) and invasion of the portal vein (93.8%, 98.5%, and 97.6%) of HCCA were, respectively. The consistency between the preoperative evaluation of resectability confirmed by IV-CEUS +IB-CEUS and MRCP was 85.4% (70/82) and 78.0% (64/82), respectively. In addition, the evaluations did not have statistically significant differences (p > 0.05). There were no significant differences between the two evaluations (p = 0.266). CONCLUSION IV-CEUS combined with IB-CEUS has significant value in classifying HCCA and evaluating the resectability of lymph node metastases, liver metastases, and vessel invasion.

Abstract
BACKGROUND Surgical resection for Bismuth-Corlette type IV (BC-IV) hilar cholangiocarcinomas, also termed Klatskin tumours are technically challenging and were once considered unresectable tumours. Following advances in hepatobiliary imaging and surgical techniques, emerging evidence suggests that surgical resection is a viable avenue for long-term survival. We aimed to identify factors affecting survival outcomes of hepatic resections for BC-IV cholangiocarcinomas. METHOD A systematic review was performed across multiple databases and several clinical trial registries. Two reviewers independently screened and selected papers that contained survival data on BC-IV cholangiocarcinoma after hepatic resections. RESULTS Of 13 499 papers from our search result, 21 papers satisfied the inclusion criteria. The median post-operative survival was 30.8 months. The average 1- and 5-year post-operative survivals were 61.6 and 33.3%, respectively. Predictors of long-term survival included achievement of R0 margins, minimisation of operative time and reduction intra-operative blood loss. CONCLUSION Our analysis demonstrates improving post-operative outcomes and survival in surgical resection of BC-IV cholangiocarcinoma and suggests that radical surgical resection is a valid treatment option for the disease.

Abstract
Local treatment of primary bile duct cancer, which grows locally at the primary lesion and seldom metastasizes to distant sites, is challenging. The present study evaluated the antitumor effect, systemic toxicity, biodistribution and survival benefit of the paclitaxel-eluting polyurethane membrane in a tumor model. Membranes containing various amounts of paclitaxel (0, 100, 300, 600 and 1,200 µg/disc) were inserted beneath the tumor mass in mouse models. Tumor size and body weight of the tumor models were monitored for 26 days after insertion of the membrane. The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay was performed in the tumor tissues. High-performance liquid chromatography was performed for evaluation of paclitaxel concentration in peripheral tissues. Tumor volumes on day 26 of membrane treatment were decreased in a dose-dependent manner. No significant difference in body weight was observed in the groups. A greater number of apoptotic cells were counted per high power field in tumor tissues following an increase of paclitaxel concentration. In the 1,200 µg-group, concentrations of paclitaxel were significantly higher in tumors compared with those of other tissues and serum. The paclitaxel-eluting membrane demonstrated a significant and dose-dependent antitumor activity, and did not exert systemic toxicity in the tumor model.

Abstract
Recent advances in dimensional imaging, surgical technique, and perioperative patient care have resulted in increased rates of complete resection with histopathologically negative margins and improved surgical outcomes in patients with extrahepatic cholangiocarcinoma. However, achieving cancer-free resection margins at ductal stumps in surgery for this disease remains challenging because of longitudinal extension, which is one of the hallmarks of extrahepatic cholangiocarcinoma. When the ductal resection margins are shown to be positive on examination of frozen sections, discrimination between carcinoma in situ and invasive carcinoma is clinically important because residual carcinoma in situ may lead to late local recurrence whereas residual invasive carcinoma is associated with early local recurrence. Residual invasive carcinoma at the ductal margins should be avoided whenever technically feasible. Residual "carcinoma in situ" at the ductal margins appears to be allowed in resection for the advanced disease because it has less effect on survival than other adverse prognostic factors (pN1 and/ or pM1). However, in surgery for early-stage (pTis-2N0M0) extrahepatic cholangiocarcinoma, residual carcinoma in situ at the ductal margins may have an adverse effect on long-term survival, so should be avoided whenever possible. In this review, we focus on the histopathological term "carcinoma in situ," the biological behavior of residual carcinoma in situ at ductal resection margins, intraoperative histological examination of the ductal resection margins, outcome of additional resection for positive ductal margins, and adjuvant therapy for patients with positive margins.

Abstract
The aim of the present study was to examine the utility of convex endoscopic ultrasonography (EUS) for the preoperative vascular evaluation of malignant biliary tract neoplasm, by comparing EUS findings with histological findings from resected specimens. Between January 2008 and January 2016, the present study retrospectively retrieved 82 cases diagnosed with malignant biliary tract neoplasm to compare findings from convex EUS with histological findings from resected specimens. A total of four groups were defined according to the results of EUS of the hepatic artery (HA) and portal vein (PV): Group 1, hyperechoic tissue between tumor and vessel; group 2, close proximity between tumor and vessel without loss of hyperechoic tissue; group 3, tumor and vessel contiguity, with loss of hyperechoic tissue; and group 4, encasement >180°. Regarding the HA, all 17 cases in groups 2 and 3 in which the tumor was close to the HA however no obvious encasement was evident, demonstrated no histological invasion, or the HA could be separated from the tumor intraoperatively. However, this was not the case for the portal vein. Of the six cases in group 3, 4 cases (66.7%) demonstrated PV invasion. Overall, convex EUS is useful for the preoperative evaluation of malignant biliary tract neoplasms, and surgery may be considered when the tumor is close to the HA on computed tomography scans, however there is no obvious encasement visualized by convex EUS.

Abstract
BACKGROUND The purpose of this study was to evaluate the prognostic index of the preoperative platelet to albumin ratio (PAR) in patients who underwent primary resection for cholangiocarcinoma. PATIENTS AND METHODS A total of 59 patients were divided into two groups: those with PAR ≥72.6×103 or <72.6×103 according to the area under the receiver operating characteristics curve. RESULTS PAR was significantly inversely associated with overall (OS) and disease-free (DFS) survival on univariate analysis. PAR showed significance on multivariate analysis for OS (hazard ratio=6.232, 95% confidence interval=1.283-30.279, p=0.023), along with tumor differentiation (p=0.009), nodal involvement (p=0.001), intraoperative blood loss (p=0.001), and serum carcinoembryonic antigen (CEA) (p=0.012). High PAR was also significantly associated poor DFS on multivariate analysis (hazard ratio(HR)=4.422, 95% confidence interval(CI)=1.168-16.732, p=0.029), along with tumor differentiation (p=0.009). CONCLUSION PAR is a useful prognostic index for OS and DFS in patients with cholangiocarcinoma after primary resection. By accumulating cases prospectively, this new index may be a reference for use before neoadjuvant chemotherapy.

Abstract
AIM: To investigate the hepatitis C virus (HCV) infection in the tissues of carcinoma of extrahepatic bile duct and study their correlation.
METHODS: HCV NS5 protein and HCV RNA were detected by labeled streptavidin biotin (LSAB) method and in situ reverse transcription polymerase chain reaction (IS-RT-PCR) in sections of 51 cases of carcinoma of extrahepatic bile duct and 34 cases of control group (without malignant biliary disease).
RESULTS: In 51 cases of carcinoma of extrahepatic bile duct, HCV NS5 protein was detected in 14 (27.5%), which was clearly stained in the cytoplasm of cancer cell but not in the nucleus or cell membrane. HCV RNA was detected in 18 (35.4%), which was located in the nucleus of cancer cell in 12 cases and in the cytoplasm in 6 cases. HCV NS5 protein and RNA coexistence was found in 2 cases. In 34 cases of control group, HCV RNA was detected in 2 (5.9%). HCV NS5 protein and RNA positive cells were found either scattered or in clusters.
CONCLUSION: The prevalence of hepatitis C viral infection in the tissues of carcinoma of extrahepatic bile duct was significantly higher than in control group (χ² = 9.808, P = 0.002). The findings suggest a correlation between HCV infection and carcinoma of extrahepatic bile duct, which is different from the traditional viewpoint. HCV infection might be involved in the development of carcinoma of extrahepatic bile duct.
