Abstract
BACKGROUND This study aimed to determine whether the back-propagation artificial neural network (BP-ANN) model could be constructed to accurately in predicting early occlusion of bilateral plastic stent placement for inoperable hilar cholangiocarcinoma (HCA). METHODS A total of 288 patients from the An Hui provincial Hospital were randomly divided into the training cohort (80%) and the internal testing cohort (20%). The predictive accuracy of the BP-ANN for predicting early occlusion of bilateral plastic stent placement of inoperable HCA was measured by the area under the curve (AUC) on receiver operating characteristic (ROC) curve analysis. The results were compared with those obtained using the conventional multivariate logistic regression analysis. RESULTS Multivariate analysis revealed that cancer stage (P=0.005) and Bismuth stage (P=0.003) were independently and significantly associated with early stent occlusion. In the training cohort, BP-ANN had larger AUC than the multivariate logistic regression model (P=0.00049). In the internal testing cohort, the AUC of the BP-ANN had larger AUC than the multivariate logistic regression model (P=0.02142). CONCLUSIONS This study showed that the BP-ANN model is a good predictive tool. It performed better than the conventional and commonly used statistical model in predicting early occlusion of bilateral plastic stent placement for inoperable HCA.

Abstract
BACKGROUND/AIMS Although endoscopic metal biliary endoprosthesis (EMBE) is widely accepted as the most suitable drainage method for patients with unresectable malignant obstruction, uncontrolled post-procedural cholangitis is still a problem. We aimed to validate a new treatment modality to prevent post-ERCP cholangitis in patients with unresectable cholangiocarcinoma. PATIENTS AND METHODS A total of 378 patients who were diagnosed with unresectable malignant biliary obstruction and underwent EMBE or temporary endoscopic nasobiliary drainage (ENBD) following EMBE placement, from January 2010 to July 2016, were enrolled in this retrospective study. Incidence of cholangitis, related infectious indicators, success rate of biliary drainage, and occurrence of complications were evaluated. RESULTS The risk of overall cholangitis and related infectious indicators was significantly lower in EMBE plus ENBD group than that in EMBE group. The occurrence of cholangitis was 2.4% versus 11.9% (P = 0.004). On further analysis of subgroups, although no difference was detected in nonhilar cholangiocarcinoma subgroup, the incidence of cholangitis and related infectious indicators in hilar cholangiocarcinoma subgroup with EMBE modality were distinctly higher than that with EMBE plus ENBD modality (type I + II was 18.5% vs 0%, P < 0.05; type III + IV was 19.8% vs 3.8%, P < 0.05). No significant difference was found in successful biliary drainage rate and procedure-related complications when all subgroups were compared. CONCLUSIONS The temporary placement of ENBD following EMBE is a simple and effective treatment modality to prevent post-ERCP cholangitis, especially in patients with hilar cholangiocarcinoma.

Abstract
This report documented the use of radiofrequency ablation (RFA) in the treatment of hepatolithiasis-associated cholangiocarcinoma and cyanoacrylate glue in the management of post-ablation bronchobiliary fistula. A 47-year-old Chinese woman with 20 years history of extrahepatic and intrahepatic cholangiolithiasis and multiple hepatic segmentectomy, developed hepatolithiasis-associated cholangiocarcinoma. The tumor was successfully treated with RFA but patient developed bronchobiliary fistula. Cyanoacrylate glue was used for occluding the bronchobiliary fistula. CT scan at 3 months showed complete restoration of physiological separation between the biliary and bronchial system. Repeat CT scan showed complete tumor ablation with no signs of tumor recurrence 10 months after RFA. In conclusion, RFA may be a safe and effective treatment option for patients with hepatolithiasis-associated cholangiocarcinoma who are poor candidates for surgical resection. Protection of the integrity of the bile duct and diaphragm during RFA can minimize postoperative complications. In case of development of post-ablation bronchobiliary fistula, cyanoacrylate glue can be used to occlude the fistula, before surgical resection is considered.

Abstract
A proteomic-based approach was used to search for potential markers in the plasma of hamsters in which cholangiocarcinoma (CCA) was induced by Opisthorchis viverrini infection and N-nitrosodimethylamine treatment. The plasma proteins of CCA-induced hamsters were resolved by 1-D PAGE, digested by trypsin, and analyzed by LC-MS/MS. From the criteria of protein ID scores >15 and an overexpression of at least three times across all time points, 37 proteins were selected. These overexpressed proteins largely consisted of signal transduction, structural, transport, and transcriptional proteins in the order. Among the most frequently upregulated proteins, exostosin 1 (EXT1) was selected for further validation. By western blot analysis, the EXT1 expression level in the plasma of hamster CCA was significantly higher than that of controls at 1 month and thereafter. Immunohistochemistry revealed that EXT1 was expressed at vascular walls and fibroblasts at 21 days (before tumor onset) and at 2 months (early CCA) posttreatment. Its expression was also observed in bile duct cancer cells during tumor progression at 6 months posttreatment. In the human CCA tissue microarray, EXT1 immunoreactivity was found not only in vascular walls and fibroblasts but also in bile duct cancer cells and was positive in 89.7 % (61/68) of the cases. By ELISA and immunoblotting, plasma EXT1 level was significantly higher in human CCA compared to healthy controls. In conclusion, these results suggest that increased expression of EXT1 level in the plasma might be involved in CCA genesis and might be a potential biomarker of CCA.

Abstract
BACKGROUND Endoscopic biliary stent drainage is effective in the palliative treatment of patients with hilar cholangiocarcinoma (HCA). However, no randomized controlled trial comparing the efficacy of the self-expandable metal stent (SEMS) and the plastic stent (PS) in patients with unresectable complex HCA is available. OBJECTIVE To compare the successful drainage rates of endoscopic SEMSs and PSs. DESIGN A single-center, open-label randomized controlled trial. SETTING University hospital in KhonKaen, Thailand. PATIENTS One hundred eight patients with unresectable complex, Bismuth type II-IV HCA. INTERVENTIONS Endoscopic retrograde cholangiography with unilateral SEMS or PS insertion. MAIN OUTCOME MEASUREMENTS Successful drainage rate. LIMITATIONS Diagnosis of HCA was made by clinical presentations, imaging studies, and clinical outcome during follow-up. RESULTS One hundred eight patients were randomly allocated to the SEMS and PS groups. Intention-to-treat analysis revealed that the successful drainage rate in the SEMS group was higher than in the PS group (70.4% vs 46.3%, P = .011). The median survival times were 126 and 49 days, respectively, in the SEMS and PS groups. The overall survival rates of the patients in both groups were statistically different by log-rank test (P = .002). CONCLUSIONS Endoscopic biliary drainage with the SEMS provides better adequacy of drainage and longer survival compared with the PS in patients with unresectable complex HCA.

Abstract
BACKGROUND AND OBJECTIVE Endoscopic or percutaneous biliary drainage with self-expandable metallic stents (SEMS) is widely used for the palliation of cholestasis in patients with advanced hilar cholangiocarcinoma. However, little is known about which is the better option in patients with advanced hilar cholangiocarcinoma. We compared the clinical outcomes of these 2 methods of biliary decompression in these patients. DESIGN AND SETTING Multicenter retrospective study. PATIENTS A total of 85 patients with newly diagnosed advanced hilar cholangiocarcinoma (Bismuth III or Bismuth IV) and who did not receive an operation, chemotherapy, or radiotherapy were retrospectively reviewed. Forty-four of the 85 received endoscopic SEMS and 41 received percutaneous SEMS. INTERVENTIONS Endoscopic SEMS or percutaneous SEMS. MAIN OUTCOME MEASUREMENTS AND RESULTS Baseline characteristics were similar in the 2 groups, but the rate of successful biliary decompression was significantly higher in the percutaneous SEMS group than in the endoscopic SEMS group (92.7% vs 77.3%, respectively, P= .049). Overall rates of procedure-related complications were similar for the 2 groups, but 1 death (from biliary sepsis) occurred in the endoscopic SEMS group. Median survival of patients in whom biliary drainage was successful initially, regardless of which procedure was performed, was much longer than that of patients who had failed biliary drainage (8.7 months vs 1.8 months, respectively, P< .001). Once successful biliary decompression had been achieved, median survival and stent patency duration were similar in the 2 study groups. LIMITATION Retrospective study. CONCLUSIONS Percutaneous SEMS may be chosen for initial biliary drainage in patients with advanced type III or IV hilar cholangiocarcinoma, given higher initial success rate and low level of procedure-related cholangitis.

Abstract
BACKGROUND/AIMS Surgical resection of choledochal cysts (CC) has become standard treatment. However, surgery is not universally recommended in early infancy and/or asymptomatic patients. In order to investigate the optimal timing of CC excision, we analyzed clinicopathological data and surgical results from different age groups. MATERIAL AND METHODS This retrospective review included 107 patients (77 females, 30 males) who underwent CC resection at the National Taiwan University Hospital between January 1988 and December 2005. Patient demographic, clinical, and surgical data were collected and analyzed. RESULTS The patients were divided into three groups according to age at the time of surgery: <1 year old (group I, n = 26), 1-16 years old (group II, n = 48), and >16 years old (group III, n = 33). About two thirds of the patients in group I had jaundice, while abdominal pain related to inflammation was the commonest symptom in groups II and III. Group I suffered significantly fewer surgical complications and less severe liver fibrosis than groups II or III. CONCLUSION CC surgery in infancy and in asymptomatic patients is safe and may prevent the complications of this condition. The results support a recommendation for early excision.

Abstract
AIM: To investigate differences in the effects of biliary drainage procedures in patients with inoperable Klatskin’s tumor based on Bismuth type, considering endoscopic retrograde biliary drainage (ERBD), external percutaneous transhepatic biliary drainage (EPTBD) and internal biliary stenting via the PTBD tract (IPTBD).
METHODS: The initial success rate, cumulative patency rate, and complication rate were compared retrospectively, according to the Bismuth type and ERBD, EPTBD, and IPTBD. Patency was defined as the duration for adequate initial bile drainage or to the point of the patient’s death associated with inadequate drainage.
RESULTS: One hundred thirty-four patients (93 men, 41 women; 21 Bismuth type II, 47 III, 66 IV; 34 ERBD, 66 EPTBD, 34 IPTBD) were recruited. There were no differences in demographics among the groups. Adequate initial relief of jaundice was achieved in 91% of patients without a significant difference in the results among different procedures or Bismuth types. The cumulative patency rates for ERBD and IPTBD were better than those for EPTBD with Bismuth type III. IPTBD provided an excellent response for Bismuth type IV. However, there was no difference in the patency rate among drainage procedures for Bismuth type II. Procedure-related cholangitis occurred less frequently with EPTBD than with ERBD and IPTBD.
CONCLUSION: ERBD is recommended as the first-line drainage procedure for the palliation of jaundice in patients with inoperable Klatskin’s tumor of Bismuth type II or III, but IPTBD is the best option for Bismuth type IV.

Abstract
BACKGROUND This study analyzed the clinical presentation, postoperative morbidity and mortality and incidence of associated extrahepatic biliary atresia in children with biliary cysts in Taiwan. METHODS We retrospectively reviewed the records of 158 pediatric patients with biliary cysts seen between June 1981 and July 2004, with follow-up ranging from 12 months to 22 years (mean, 11.2 +/- 6.1 years). Patients were divided into three groups: biliary atresia-associated biliary cyst (BABC, 21 patients), non-biliary atresia-associated choledochal cyst (NBACC) in infancy (37 patients), and late NBACC (> 1 year of age, 100 patients). RESULTS BABC accounted for 36.2% of the infantile biliary cysts in this study. Extrahepatic cysts in late NBACC had a greater mean diameter than those in infantile NBACC and BABC (21.5 mm vs. 16.0 mm vs. 7.9 mm, p < 0.001). Cholangitis was the most serious complication within 3 months postoperatively in all three groups, resulting in four deaths (two in the infantile NBACC group and one each in the other two groups). Liver cirrhosis developed during long-term follow-up in nine of the 21 patients with BABC, four of whom died. Three of these nine patients underwent liver transplantation and remained well during follow-up. Chronic complications in NBACC occurred mainly in late IVa cases, with persistent intrahepatic dilatation developing in 12 of 35 patients and intrahepatic stones in five. Elevation of serum alanine aminotransferase (ALT) was found preoperatively in 85% of late NBACC and 35% of infantile NBACC cases. Postoperative normalization of ALT occurred after a mean of 152 +/- 23 days and 158 +/- 67 days in late NBACC and infantile NBACC, respectively. Higher ALT levels before operation were associated with a longer period until normalization. CONCLUSION The possibility of BABC must be included in the differential diagnosis when a small extrahepatic cyst (< 8 mm in diameter) with prolonged jaundice is found in infancy. Postoperative follow-up is essential for patients with NBACC due to their frequently prolonged elevation of serum ALT and possibility of residual intrahepatic dilatation. Cholangitis was the major cause of death within 3 months postoperatively in this study.

Abstract
Patients with hilar obstruction usually require bilateral biliary drainage. The prognosis of patients who fail bilateral biliary drainage after contrast injection into both intrahepatic ducts is poor due to a high infection rate in the undrained segments. The incidence of post-endoscopic retrograde cholangiopancreatography cholangitis in those with successful bilateral biliary drainage was less, but still significant. Incomplete subsegmental intrahepatic duct drainage is suggested to be responsible for post-biliary drainage cholangitis in cases of advanced hilar tumors. This study was undertaken to determine the incidence of post-endoscopic retrograde cholangiopancreatography cholangitis, jaundice resolution, and stent clogging in different types of malignant biliary obstruction after biliary drainage. From our endoscopic retrograde cholangiopancreatography database, there were 63 patients who underwent endoscopic biliary drainage between September 2000 and November 2001, for malignant biliary obstruction. Sixty-one endoscopic retrograde cholangiopancreatographies had biliary drainage performed (2 patients who failed biliary drainage were excluded). We divided our patients into 3 groups: Group 1 = Bismuth I, Group 2 = Bismuth II, and Group 3 = Bismuth III and IV. All but 2 Group 1 patients had successful biliary endoprosthesis (plastic [n = 13], metallic [n = 12], failed [n = 2]) placement into an extrahepatic duct. All patients from Group 2 (n = 10) and 20 patients from Group 3 (n = 26) had successful bilateral biliary drainage. Unilateral biliary drainage was performed in 6 patients from Group 3, each with a plastic endoprosthesis. The incidence of post-biliary drainage cholangitis (new onset of fever >38.5 degrees C with leukocytosis), jaundice resolution (normal bilirubin level), and the duration of endoprosthesis patency were compared among the 3 groups. The incidences of post-endoscopic retrograde cholangiopancreatography cholangitis, jaundice resolution, and the duration of endoprosthesis patency were: Group 1 (4%, 96%, and 87.2 days, respectively), Group 2 (10%, 100%, and 69.1 days, respectively) and Group 3 (57.7%, 73.1%, and 41.3 days, respectively). Of those patients who did not undergo surgery, patients from Group 3 required endoprosthesis exchange sooner than others. The outcome of biliary drainage in patients with advanced hilar tumors (Bismuth III or IV) was poorer than hilar tumor at earlier stages (Bismuth I or II).
