Abstract
BACKGROUND AND AIMS Single-operator cholangioscopy-assisted electrohydraulic lithotripsy (SOC-EHL) is effective and safe in difficult choledocholithiasis. The optimal timing of SOC-EHL use, however, in refractory stones has not been elucidated. The following aims to determine the most cost-effective timing of SOC-EHL introduction in the management of choledocholithiasis. METHODS A cost-effectiveness model was developed assessing three strategies with a progressively delayed introduction of SOC-EHL. Probability estimates of patient pathways were obtained from a systematic review. The unit of effectiveness is complete ductal clearance without need for surgery. Cost is expressed in 2018 US dollars and stem from outpatient US databases. RESULTS The three strategies achieved comparable ductal clearance rates ranging from 97.3% to 99.7%. The least expensive strategy is to perform SOC-EHL during the first endoscopic retrograde cholangiography pancreatography (ERCP) (SOC-1: 18,506$). The strategy of postponing the use of SOC-EHL to the third ERCP (SOC-3) is more expensive (US$18,895) but is 2% more effective. (0.9967). SOC-EHL during the second ERCP in the model (SOC-2) is the least cost-effective. Sensitivity analyses show altered conclusions according to the cost of SOC-EHL, effectiveness of conventional ERCP, and altered willingness-to-pay (WTP) thresholds with early SOC-1 being the most optimal approach below a WTP cut-off of US$20,295. CONCLUSIONS Early utilization of SOC-EHL (SOC-1) in difficult choledocholithiasis may be the least costly strategy with an effectiveness approximating those achieved with a delayed approach where one or more conventional ERCP(s) are reattempted prior to SOC-EHL introduction.

Abstract
Patients with cholangiocarcinoma have poor survival since the majority of patients are diagnosed at a stage precluding surgical resection, due to locally irresectable tumors and/or metastases. Optimization of diagnostic strategies, with a principal role for tissue diagnosis, is essential to detect cancers at an earlier stage amenable to curative treatment. Current barriers for a tissue diagnosis include both insufficient tissue sampling and a difficult cyto- or histopathological assessment. During endoscopic retrograde cholangiopancreatography, optimal brush sampling includes obtaining more than one brush within an individual patient to increase its diagnostic value. Currently, no significant increase of the diagnostic accuracy for the new cytology brush devices aiming to enhance the cellularity of brushings versus standard biliary brush devices has been demonstrated. Peroral cholangioscopy with bile duct biopsies appears to be a valuable tool in the diagnostic work-up of indeterminate biliary strictures, and may overcome current technical difficulties of fluoroscopic-guided biopsies. Over the past years, molecular techniques to detect chromosomal instability, mutations and methylation profiling of tumors have revolutionized, and implementation of these techniques on biliary tissue during diagnostic work-up of biliary strictures may be awaited in the near future. Fluorescence in situ hybridization has already been implemented in routine diagnostic evaluation of biliary strictures in several centers. Next-generation sequencing is promising for standard diagnostic care in biliary strictures, and recent studies have shown adequate detection of prevalent genomic alterations in KRAS, TP53, CDKN2A, SMAD4, PIK3CA, and GNAS on biliary brush material. Detection of DNA methylation of tumor suppressor genes and microRNAs may evolve over the coming years to a valuable diagnostic tool for cholangiocarcinoma. This review summarizes optimal strategies for biliary tissue sampling during endoscopic retrograde cholangiopancreatography and focuses on the evolving molecular techniques on biliary tissue to improve the differentiation of benign and malignant biliary strictures.

Abstract
INTRODUCTION Endoscopic removal of common bile duct stones has a high success rate ranging from 85% to 95%. Bile duct stones >15 mm are difficult and frequently require lithotripsy. Peroral cholangioscopy (POC) allows lithotripsy with similar success rates. AIM To determine the efficacy and safety of cholangioscopy-guided lithotripsy used in the treatment of difficult to remove bile duct stones vs. conventional therapy. METHODS Search was based in Medline, Embase, Cochrane Central, Lilacs/Bireme. Studies enrolling patients referred for the removal of difficult bile duct stones via POC were considered eligible. Two analyses were carried out separately, one included randomized controlled trials (RCTs) and another observational studies. RESULTS Forty-six studies were selected (3 RTC and 43 observational). In the analysis there was no statistical significant difference between successful endoscopic clearance (RD=-0.02 CI: -0.17, 0.12/I²=0%), mean fluoroscopy time (MD=-0.14 CI -1.60, 1.32/I²=21%) and adverse events rates (RD=-0.06 CI: -0.14, 0.02/I²=0%), by contrast, the mean procedure time favored conventional therapy with statistical significance (MD=27.89 CI: 16.68, 39.10/I²=0%). In observational studies, the successful endoscopic clearance rate was 88.29% (CI95: 86.9%-90.7%), the first session successful endoscopic clearance rate was 72.7 % (CI95: 69.9%-75.3%), the mean procedure time was 47.50±6 min for session and the number of sessions to clear bile duct was 1.5±0.18. The adverse event rate was 8.7% (CI95: 7%-10.9%). CONCLUSIONS For complex common bile duct stones, cholangioscopy-guided lithotripsy has a success rate that is similar to traditional ERCP techniques in terms of therapeutic success, adverse event rate and means fluoroscopy time. Conventional ERCP methods have a shorter mean procedure time.

Abstract
Laparoscopic left hemihepatectomy (LLH) followed by biliary tract exploration is used to treat left-sided hepatolithiasis (LSH). The purpose of this study was to compare the efficacy of 2 methods of biliary tract exploration in LLH:biliary tract exploration through a common bile duct (CBD) incision (with T-tube drainage) or through the left hepatic duct (LHD) stump (without T-tube drainage).LSH patients (113 patients) were recruited retrospectively in our hospital from December 2008 to January 2016. To compare different methods of biliary tract exploration during LLH, the patients were divided into 2 groups: 41 patients underwent biliary tract exploration through the LHD stump (LHD group), and 72 patients underwent biliary tract exploration through a CBD incision (CBD group). Baseline characteristics, surgical outcomes, surgery-related complications, postoperative hospital stay (PHS) and long-term results were compared between the 2 groups.There was no unplanned reoperation in the 2 groups. One patient in the CBD group had a residual stone, which was removed by choledochoscopy 2 months postoperation. Two patients in the LHD group and 3 patients in the CBD group had bile leakage and were cured with abdominal drainage. There were no significant differences in the total operation time, incidence of residual stones and bile leakage between the 2 groups (P > .05). The PHS and the incidence of hypokalemia or hyponatremia in the LHD group were significantly lower than those in the CBD group (P < .05). T-tube-related complications occurred in 13.9% (10/72) of the CBD patients. The mean follow-up period was 37.2 ± 13.8 months. There were no significant differences in the incidence of recurrence stones or cholangitis (P > .05) between the 2 groups.Exploration of the biliary tract through the LHD stump without T-tube drainage is safe with satisfactory short- and long-term results for selected LSH patients.

Abstract
Hepatolithiasis is the presence of calculi within the intrahepatic bile duct specifically located proximal to the confluence of the left and right hepatic ducts. The ultimate goal of hepatolithiasis treatment is the complete removal of the stone, the correction of the associated strictures and the prevention of recurrent cholangitis. Although hepatectomy could effectively achieve the above goals, it can be restricted by the risk of insufficient residual liver volume, and has a 15.6% rate of residual hepatolithiasis. With improvements in minimally invasive surgery, post-operative cholangioscopy (POC), provides an additional option for hepatolithiasis treatment with higher clearance rate and fewer severe complications. POC is very safe, and can be performed repeatedly until full patient benefit is achieved. During POC three main steps are accomplished: first, the analysis of the residual hepatolithiasis distribution indirectly by imaging methods or directly endoscopic observation; second, the establishment of the surgical pathway to relieve the strictures; and third, the removal of the stone by a combination of different techniques such as simple basket extraction, mechanical fragmentation, electrohydraulic lithotripsy or laser lithotripsy, among others. In summary, a step-by-step strategy of POC should be put forward to standardize the procedures, especially when dealing with complicated residual hepatolithiasis. This review briefly summarizes the classification, management and complications of hepatolithiasis during the POC process.
