Abstract
BACKGROUND Although numerous retrieval baskets are currently available for the extraction of bile duct stones, their mechanical properties have not been evaluated. This study aimed to ascertain the characteristics of retrieval baskets for bile duct stones by examining their mechanical properties. METHODS This experimental study tested the mechanical properties of seven retrieval baskets for bile duct stones. The radial force (RF) was measured using a dedicated measurement device and the axial force (AF) was measured using the conventional manual method. RESULTS The mean RF differed significantly among the baskets (p < 0.001) and was the strongest for VorticCatch (1.62 N ± 0.02) and COAXIS (1.62 N ± 0.04), followed by RASEN (1.27 N ± 0.02), Memory Basket (0.95 N ± 0.01), 8-wire Nitinol Basket (0.93 N ± 0.01), StoneHunter (0.78 N ± 0.01) and Flower Basket (0.37 N ± 0.01), respectively. The mean AF differed significantly among the baskets (p < 0.001) and was the highest for VorticCatch (0.668 N ± 0.032), followed by COAXIS (0.629 N ± 0.041), StoneHunter (0.574 N ± 0.037), 8-wire Nitinol Basket (0.546 N ± 0.010), Memory Basket (0.542 N ± 0.024), RASEN (0.435 N ± 0.008) and Flower Basket (0.297 N ± 0.011), respectively. The baskets were categorized into four groups with comparable mechanical properties based on the RF and AF: group 1, low RF and low AF; group 2, moderate RF and moderate AF; group 3, high RF and moderate AF; and group 4, high RF and high AF. CONCLUSIONS This study revealed distinct mechanical properties of various retrieval baskets used for extracting bile duct stones, which may enhance the understanding of their action. Our results could also aid the development of retrieval baskets in future.

Abstract
There are still many physicians who are reluctant to use primary biliary suture in Laparoscopic common bile duct exploration (LCBDE) for fear of more complications. We compare and analyze the clinical effectiveness of bile duct primary suture with three laparoscopic ports and indwelling T-tube drainage (with four laparoscopic ports) in patients with choledocholithiasis after LCBDE. Clinical data of 135 patients with common bile duct (CBD) stone were compared, including general conditions, postoperative hospital stay, postoperative complications, hospitalization costs, postoperative follow-up and other indicators. Forty-eight patients underwent primary suture of bile duct (group A) and 87 were treated with external T-tube drainage (group B). There were no significant differences between the two groups neither relating to the age, gender, BMI, diameter of CBD, number of stones, preoperative bilirubin value, number of previous surgeries in preoperative, nor the operation time, residual stones, the number of cases converted from laparoscopic conversion to laparotomy. The postoperative complications like fever, bleeding, incision infection, bile duct stricture has no differences between two group. The incidence of bile leakage (p = 0.008) and postoperative electrolyte disturbance (p = 0.001) were slightly lower in group A. There were fewer postoperative complications in group A vs group B (p = 0.04). Patients in group A experienced shorter postoperative hospital stay (p < 0.001), earlier postoperative extubation (p < 0.001), lower total hospitalization costs (p = 0.03), and earlier postoperative recovery (p = 0.000). Primary suture of CBD is a safe and effective method for some patients after LCBDE.

Abstract
BACKGROUND Since the introduction of the Critical View of Safety approach in laparoscopic cholecystectomy, exposure of the common bile duct, and common hepatic duct is not recommended, therefore, the length of the cystic duct remnant is no longer controlled. The aim of this case‒control study is to evaluate the relationship between the length of the cystic duct remnant and the risk for bile duct stone recurrence after cholecystectomy. METHODS All MRIs with dedicated sequences of the biliary tract taken between 2010 and 2020 from patients who underwent prior cholecystectomy were reviewed. The length of the cystic duct remnant was measured and compared between the patients with and without bile duct stones using multivariate logistic regression analysis. RESULTS A total of 362 patients were included in this study, 23.5% of whom had bile duct stones on MRI. The cystic duct remnant was significantly longer in the patients with stones than in the control group (median 31 mm versus 18 mm, P < 0.001). In the MRIs performed > 2 years after cholecystectomy, the cystic duct remnant was also significantly longer in the patients with bile duct stones (median 32 mm versus 21 mm, P < 0.001). A cystic duct remnant ≥ 15 mm in length increased the odds of stones (OR = 2.3, P = 0.001). Overall, the odds of bile duct stones increased with an increasing cystic duct remnant length (≥ 45 mm, OR = 5.0, P < 0.001). CONCLUSIONS An excessive cystic duct remnant length increases the odds of recurrent bile duct stones after cholecystectomy.

Abstract
BACKGROUND Unnecessary endoscopic retrograde cholangiopancreatography (ERCP) after spontaneous passage of common bile duct stones (CBDSs) should be avoided. This study aimed to examine the cumulative diagnosis rate and the predictive factors of spontaneous CBDS passage during the interval between the imaging diagnosis and ERCP. METHODS This multicenter retrospective study included 1260 consecutive patients with native papilla diagnosed with CBDSs using imaging modalities. Predictive factors and cumulative diagnosis rate of spontaneously passed CBDSs during the interval between imaging diagnosis and ERCP were analyzed. RESULTS The overall cumulative diagnosis rate of spontaneous CBDS passage was 6.2% (78/1260) during a mean interval of 5.0 days. In the multivariate analysis, CBDS sized < 6 mm on diagnostic imaging, solitary CBDS on diagnostic imaging, intervals between the imaging diagnosis and ERCP, and nondilated common bile duct (< 10 mm) were the significant factors associated with spontaneous CBDS passage. Specifically, the cumulative diagnosis rate of spontaneous passage was significantly higher in patients with solitary and CBDSs sized < 6 mm than in those with other CBDSs (14.4% [54/376] vs. 2.7% [24/884], P < 0.001). In both the asymptomatic and symptomatic groups, the cumulative diagnosis rate of the spontaneous passage of CBDSs was significantly higher in patients with solitary and CBDSs sized < 6 mm on diagnostic imaging than in those with multiple and/or CBDSs sized ≥ 6 mm on diagnostic imaging during a mean interval of 20.5 and 2.4 days, respectively (asymptomatic group: 22.4% [15/67] vs. 3.5% [4/113], P < 0.001, symptomatic group: 12.6% [39/309] vs. 2.6% [20/771], P < 0.001). CONCLUSIONS Solitary and CBDSs sized < 6 mm on diagnostic imaging can often lead unnecessary ERCP due to spontaneous passage. Preliminary endoscopic ultrasonography immediately before ERCP is recommended, especially in patients with solitary and small CBDSs on diagnostic imaging.

Abstract
BACKGROUND Limited endoscopic sphincterotomy with large balloon dilation (ES-LBD) and endoscopic papillary large-balloon dilation (EPLBD) have been proven safe and effective for removal of bile duct stones. However, the long-term outcomes are not clear. The aim of this study was to assess the long-term outcomes of EPLBD (12-15 mm) with or without limited sphincterotomy for removal of common bile duct (CBD) stones. METHODS Patients with EPLBD or ES-LBD referred for the removal of bile-duct stones between June 2008 and August 2020 were retrospectively reviewed. Complete stone clearance, endoscopic retrograde cholangiopancreatography (ERCP)-related adverse events, and late biliary complications during long-term follow-up were analyzed. RESULTS Basic patient characteristics were not significantly different between the groups that underwent EPLBD (n = 168) and ES-LBD (n = 57). EPLBD compared with ES-LBD resulted in similar outcomes in terms of overall successful stone removal (99.4% vs. 100%, P = 1.00) and ERCP-related adverse events (7.7% vs. 5.3%, P = 0.77). The mean duration of the follow-up was 113.6 months and 106.7 months for patients with EPLBD and ES-LBD, respectively (P = 0.13). There was no significant difference between EPLBD and ES-LBD in the incidence of stone recurrence [20 (11.9%) vs. 9 (15.8%); P = 0.49]. Multivariate analysis showed that a diameter of CBD ≥ 15 mm (OR = 3.001; 95% CI: 1.357-6.640; P = 0.007) was an independent risk factor for stone recurrence. CONCLUSIONS The application of a large balloon (12-15 mm) via EPLBD is an effective and safe alternative to ES-LBD for extraction of large CBD stones. Endoscopic sphincterotomy prior to EPLBD may be unnecessary. A diameter of CBD ≥ 15 mm is a risk factor of stone recurrence.

Abstract
BACKGROUND Stone removal using endoscopic papillary large balloon dilation (EPLBD) is extremely effective. However, limited research exists regarding the risk factors for perforation of the duodenal papilla and bile duct, which may be fatal. AIMS We aimed to investigate the risk factors for perforation during EPLBD + stone removal. METHODS We included patients who underwent EPLBD + stone removal at four medical facilities between January 2008 and December 2018. We retrospectively analyzed the risk factors for perforation and their relationship between overdilation and adverse events. Overdilation was defined as a ratio of the balloon diameter to the diameter of the bile duct that exceeded 100%. The diameter of the distal bile duct was measured using the diameter of the intrapancreatic bile duct at a point 10 mm toward the liver from the narrow distal segment on a cholangiogram. RESULTS We included 310 patients (177 males; median age: 79 years [range: 46-102 years]). Perforation occurred in five patients (1.6%). Multivariate analysis indicated that no surrounding-pancreas (half or less of the circumference of the intrapancreatic bile duct was surrounded by the pancreatic parenchyma) was a significant risk factor (perforation rate: 8.3%, p = 0.011, odds ratio: 12.7 [95% confidence interval: 1.8-90.5]). No significant difference was found between the overdilation and non-overdilation groups regarding the occurrence of pancreatitis, bleeding, and cholangitis. Perforation rate in patients with no surrounding pancreas + overdilation was 16.7% (2/12). Patients with perforation underwent conservative therapy, which improved their conditions. CONCLUSIONS EPLBD + stone removal should be avoided in patients with no surrounding pancreas. Overdilation is not a risk factor for adverse procedural events; however, it should be limited in patients with surrounding pancreas.

Abstract
BACKGROUND The practice of managing suspected/confirmed common bile duct stones (CBDS) can vary significantly in the UK. We aimed to assess this variability in practice and challenges to form a basis for future consensus. METHODS An electronic survey containing 40 questions on various aspects of management of CBDS was sent to surgeons who perform cholecystectomies via five surgical associations. RESULTS A total of 132 surgeons responded to the survey. The speciality of surgeons includes upper gastro-intestinal (68%), general (18%), colorectal (12%), and others (2%). For patients with suspected CBD stones, 80% would choose magnetic resonance cholangio-pancreatography, and 14.4% would proceed to intra-operative imaging. Most surgeons preferred intra-operative cholangiogram over intra-operative ultrasound (83% vs 17%). For the treatment, 62.1% preferred a two-stage approach [endoscopic retrograde cholangio-pancreatography (ERCP) followed by laparoscopic cholecystectomy (LC)] and 33.4% chose a single-stage approach [LC + laparoscopic common bile duct exploration (LCBDE)]. Eighty (60.6%) responders performed LCBDE, and 19 (23.8%) of them performed > 10 LCBDEs in a year. Two third of surgeons (62.5%) preferred a trans-choledochal approach to CBDS. Half of the surgeons that perform LCBDE use a T-tube selectively and 1.6% routinely. The "availability of very good ERCP service" and "lack of formal training" were the two main reasons for surgeons not performing LCBDE. Both surgeons' speciality and whether they perform other complex laparoscopic surgery were significantly associated with choosing a two-stage approach over a one-stage approach (χ2 test, speciality p = 0.033, complex surgery p = 0.011). CONCLUSION Our survey confirms the significant variability in the diagnosis and management of CBDS. The two-stage approach is still the most common way of managing CBDS in the UK. The main reasons for the low uptake of the single-stage approach are the availability of good ERCP service, lack of equipment and lack of formal training in the technique of LCBDE.

Abstract
BACKGROUND/AIMS After endoscopic treatment of common bile duct (CBD) stones, recurrence of choledocholithiasis due to small stone fragments and post-endoscopic retrograde cholangiopancreatography (post-ERCP) cholangitis can occur. We determined the effect of biliary stenting after removal of CBD stones on the recurrence of CBD stones and the incidence of post-ERCP cholangitis. METHODS We performed a retrospective single-center study involving 483 patients who underwent ERCP for the removal of CBD stones. The patients were classified into two groups according to their biliary stenting status. The primary outcome was the rate of CBD stone recurrence and the secondary outcome was the incidence of post-ERCP cholangitis. RESULTS Among the 483 patients, 219 and 264 did and did not receive a biliary stent after CBD stone removal, respectively. The incidence of stone recurrence was 15.5% and 7.6% in the non-stenting and stenting groups (p = 0.006), respectively, while the incidence of post-ERCP cholangitis was 4.6% and 2.7% (p = 0.256). In a multivariate analysis, biliary stenting significantly reduced the stone recurrence rate (odds ratio, 0.30; p = 0.004). CONCLUSION Biliary stenting after the removal of CBD stones reduces the stone recurrence rate and assisted recovery. For patients with large and multiple stones who undergo lithotripsy, preventive biliary stent insertion can reduce the rate of stone recurrence.

Abstract
AIM The present study was performed on patients with large bile duct stones to compare clinical outcomes and complications of balloon dilatation treatment between two sizes of balloons, < 15 mm and ≥ 15 mm. BACKGROUND in 1982, the endoscopic papillary balloon dilatation (EPBD) method was presented by Staritz to reduce bleeding and perforation risk of large bile duct stones. METHODS Patients with large bile duct stones admitted to Taleghani hospital from December 2018 to December 2019 who were the candidates for balloon dilation with limited sphincterotomy. Patients were randomly divided into two groups. In group B, a ≥ 15 mm balloon was used, and in group A, a balloon <15 mm was used. The clinical results of balloon dilation and its complications were recorded and compared. RESULTS Most patients had 1 or 2 large bile duct stones, and there was no significant difference in the number of stones. Extraction was successful in 92.8% of group B and 85.7% of group A without significant differences (P = 0.8). Pancreatitis, hemorrhage, cholangitis, and perfusion occurred in 8%, 4.2%, 1.4%, and 2.8% of group B subjects and also in 10%, 2.8%, 0%, and 1.4% of group A subjects, respectively, and the difference between the two groups was not significant. CONCLUSION Generally, this study results showed that balloon size did not have a significant effect on the success rate of bile duct stones. Moreover, considering the lack of significant association between balloon dilatation size and the occurrence of post-endoscopic complications such as pancreatitis, it seems that large-size dilatation has no serious clinical risk.

Abstract
PURPOSE This study aimed to examine the correlation between right posteroinferior bile duct (RPBD) angulation and the occurrence of bile duct stones in patients with hepatolithiasis. METHODS Patients presenting with hepatolithiasis in our hospital from January 2011 to July 2016 were divided into two groups according to whether their RPBD was affected by stones. A statistical analysis for the relevant factors associated with bile duct stone formation in the RPBD was performed. RESULTS The binary logistic regression results showed that stenosis of the right hepatic duct [odds ratio (OR): 7.313; 95% confidence interval (CI) 4.131-12.945)] and the angle of the RPBD (OR 0.896; 95%CI 0.877-0.916) were risk factors associated with the formation of RPBD stones. Further, the receiver operating characteristic curve indicated that, when the angle of the RPBD was less than 44.58°, stones were able to form more easily in the RPBD. CONCLUSION The occurrence of bile duct stones is well correlated with sharp bile duct angulation.

Abstract
Choledocholithiasis is a common disorder that is managed universally by endoscopic retrograde cholangiopancreatography (ERCP). For difficult or complex stones, ERCP with conventional techniques may fail to achieve biliary clearance in 10% to 15% of cases. This review summarizes the literature regarding the current available endoscopic techniques for complex stone disease, including mechanical lithotripsy, endoscopic papillary large balloon dilation, cholangioscopy-guided lithotripsy, and endoscopic ultrasound-guided biliary access.

Abstract
BACKGROUND AND AIM Cholangiocarcinoma (CCA) often develops after the hepatic resection for hepatolithiasis as well as indwelling it. We studied the incidence and prognosis of subsequent CCA in patients with hepatolithiasis in South Korea. METHODS We identified individuals with diagnosed CCA at the time of or after surgery, during 2002-2016, from the Korean National Health Insurance. The incidences and survival rates of subsequent CCA were analyzed and compared with concomitant CCA. The standardized incidence ratios (SIRs) of CCA in this cohort were evaluated in the standard Korean population. All data were stratified by the presence of intrahepatic or extrahepatic CCA, age and sex. RESULTS Of the 7852 patients with hepatectomy for BDS, 433 (5.84%) had concomitant CCA. Over the 12-year follow-up, 107 of 7419 (1.98%) patients were diagnosed with subsequent CCA. Patients with hepatic resection for BDS revealed higher SIRs for subsequent CCA (12.89, 95% CI 10.96-15.15) in cases of both intrahepatic CCA (13.40, 10.55-17.02) and extrahepatic CCA (12.42, 9.98-15.46). The median survival time for subsequent CCA was 0.87 years, while that for concomitant CCA was 2.79 years. Having subsequent CCA (HR 2.71, 95% CI 2.17-3.40) and being male (HR 1.28, 1.05-1.57) were related to a shorter survival time. The CCA site and age at CCA diagnosis were not related to prognoses. CONCLUSIONS Subsequent CCA developed in 2% of the patients with hepatic resection for benign BDS until 10 years and was associated with poorer prognoses than concomitant CCA. Future studies focused on the long-term surveillance for CCA in such patients are needed.

Abstract
AIM To investigate the characteristics of biliary pathogenic bacteria, pathological changes of bile ducts, and changes of duodenal papilla in patients with bile duct stones and pneumatosis.
METHODS We analyzed biliary pathogenic bacteria, pathological changes of bile ducts, and characteristics of duodenal papilla in 53 patients with bile duct stones and pneumatosis. The incidence of intestinal juice reflux and recurrent biliary infection and bile duct diameter were compared in each subtype of duodenal papilla.
RESULTS The results of bacterial culture showed that the percentages of Gram positive bacteria, Gram negative bacteria, and fungi were 42.1%, 57.9%, and 1.8%, respectively. The main bacteria were Enterococcus (36.6%), Escherichia coli (19.3%), and Klebsiella pneumoniae (15.8%). Chronic bile duct inflammation, duodenal papillary inflammation, incomplete closure of duodenal papilla, and Oddi sphincter relaxation were common features in patients with bile duct stones and pneumatosis. Chronic inflammation and abnormal hyperplasia of the bile duct mucosa were found in 16 patients, which manifested as intestinal villous change, mucous pits, and reticular pattern. Seven patients had local mass in the bile duct. There was a significant difference in bile duct diameter among each subtype of papilla (P < 0.001). Common bile duct diameter was significantly bigger in IIb and IIc subtypes than in IIa and IId subtypes (P < 0.05), but there was no significant difference between IIb and IIc and between IIa and IId (P > 0.05). The rate of intestinal juice reflux differed significantly among each subtype of papilla (P < 0.05), and the rate of intestinal juice reflux was significantly higher in IIa subtype than in other subtypes. However, the rate of recurrent biliary infection showed no significant difference among each subtype of papilla (P > 0.05).
CONCLUSION Bacterial infection is the main etiology in patients with bile duct stones and pneumatosis, and the percentage of Gram positive bacteria is higher. Chronic bile duct inflammation, duodenal papillary inflammation, incomplete closure of duodenal papilla, and Oddi sphincter relaxation are common features in patients with bile duct stones and pneumatosis. There is a significant difference in bile duct diameter and the rate of intestinal juice reflux among each subtype of duodenal papilla, while there is no significant difference in the rate of recurrent biliary infection.

Abstract
Acute cholangitis is a fatal condition if inadequately treated. It is possible to underestimate the severity of the condition because bacterial cultures are not immediately available. We evaluated the clinical features of patients with cholangitis due to bile duct stones who were diagnosed with severe bacteremia at the time of hospitalization, but not at the time of the initial visit. We conducted a retrospective analysis of cases of endoscopic retrograde cholangiopancreatography performed between January 2007 and October 2011 in patients with bile duct stones complicated by cholangitis. The severity of cholangitis was assessed based on the 2005 Japanese Evidence-Based Practice Guidelines for the Management of Acute Cholangitis and Cholecystitis (JG05). Of 130 cases, 23 were diagnosed as severe cholangitis, including 11 of bacterial cause. However, based on the JG05, two cases were classified as “mild” at initial assessment and nine cases as “moderate”. A history of endoscopic sphincterotomy (EST) was identified in the two cases classified as “mild” cholangitis. Obstruction by a bile duct stone, possibly due to reflux from the duodenum, can lead to rapid progression to sepsis in a short time. For patients with a history of EST, early biliary drainage is necessary to prevent rapid progression of bacterial cholangitis.

Abstract
We report a rare case of bile duct stone formation around an ingested fish bone as a nidus after pancreatoduodenectomy. A 78-year-old woman was admitted to our department for fever and epigastric pain. Abdominal computed tomography revealed an elongated bile duct stone containing a linearly shaped foreign body of bone density. Enteroscopic lithotomy was performed using single balloon enteroscopy to safely remove the stone and foreign body from the bile duct. The foreign body was determined to be a fish bone by pathological examination and component analysis.

Abstract
AIM To examine the influence of night duty (ND) on endoscopic therapy for biliary duct stones.
METHODS The subjects consisted of 133 patients who received initial endoscopic therapy for biliary duct stones performed by eight endoscopists after they had been on (ND group, n = 34 patients) or not [day duty (DD) group, n = 99 patients]. Patient characteristics (age, gender, history of abdominal surgery, transverse diameter of the largest stone, number of stones), years of experience of the endoscopists, endoscopic procedures [sphincterotomy, papillary balloon dilation (EPBD), papillary large balloon dilation (EPLBD)], and outcomes of initial endoscopy (procedure time; rate of stone removal by the first endoscopist; procedure success rate by the first endoscopist: removal of stones or endoscopic retrograde biliary drainage; rate of final stone removal; final procedure success rate; complications; hospitalization after the procedure) were compared retrospectively between the two groups. History of abdominal surgery and treatment outcomes were also compared between the groups for each of the four endoscopists who performed most of the procedures in the ND group.
RESULTS There were no significant differences regarding the number of treatments performed by each endoscopist or the years of experience between the ND and DD groups. The frequency of endoscopic retrograde cholangiopancreatography procedures did not differ significantly between the groups. There were also no significant differences regarding patient characteristics: age, gender, history of abdominal surgery (ND 7: Billroth II 4, R-Y 3; DD 18: double tract reconstruction 1, Billroth I 3, Billroth II 6, R-Y 7, duodenoduodenostomy for annular pancreas 1), transverse diameter of largest stone, and number of stones between the two groups. Among the treatment procedures, the endoscopic sphincterotomy and EPBD rates did not differ significantly between the groups. However, EPLBD was performed more frequently in the ND group [47.1% (16/34) vs 19.2% (19/99)]. Regarding outcomes, there were no significant differences in the rate of stone removal, procedure success rate, complications (ND: pancreatitis 1; DD: pancreatitis 6, duodenal bleeding 1, decreased blood pressure 1, hypoxia 2), or hospitalization after the procedure. However, the procedure time was significantly longer in the ND group (71.5 ± 44.7 vs 54.2 ± 28.8). Among the four endoscopists, there were no significant differences in patient history of abdominal surgery, removal of stones, or procedure success rate. However, the procedure time for one endoscopist was significantly longer in the ND group.
CONCLUSION The time required for endoscopic therapy for bile duct stones might be influenced by ND.

Abstract
BACKGROUND Endoscopic papillary large balloon dilatation (EPLBD) without endoscopic sphincterotomy (EST) is an accepted, simplified endoscopic technique for large common bile duct (CBD) stone removal. However, little is known about the long-term outcomes of this technique. The purpose of this study was to evaluate the long-term outcomes of EPLBD without EST for the treatment of large CBD stones. METHODS This retrospective study of EPLBD without EST for a large CBD stone was conducted between June 2005 and October 2010. A total of 128 patients with a large CBD stone were included. The primary outcome measurement was complete CBD stone removal after EPLBD. Clinical data obtained from medical records were analyzed. RESULTS The overall complete stone removal rate was 94.5 %. Mechanical lithotripsy was needed in 18 (14.1 %) patients. Post-procedural pancreatitis and asymptomatic hyperamylasemia occurred in 1 (0.8 %) and 11 (8.6 %) patients, respectively. One (0.8 %) patient experienced minor bleeding. The rate of stone recurrence was 13.1 %, and median time to stone recurrence was 600 days (range 144-2284 days). Over a half (64.3 %) of stone recurrences occurred during the 2 years following stone removal. Recurrence tended to be more frequent in patients with a large CBD diameter and in patients requiring multiple endoscopic sessions for complete CBD stone retrieval. CONCLUSION EPLBD without EST may be safe and effective in patients with a large bile duct stone.

Abstract
BACKGROUND The incidence of biliary tract stones has widely been reported to be high after gastrectomy. Treatment of biliary tract stones in post-gastrectomy patients was examined retrospectively, particularly minimally invasive therapy with laparoscopic cholecystectomy for gallbladder stones and endoscopic bile duct lithotomy for common bile duct stones. METHODS Treatment of 122 post-gastrectomy patients with biliary tract stones was examined retrospectively from 1995 to April 2015. RESULTS Symptomatic biliary tract stones were found in 3.7% of post-gastrectomy patients. The frequency of bile duct stones was higher in post-gastrectomy patients with gallbladder stones (44%) than in the nongastrectomy patients (11%). Laparoscopic cholecystectomy was carried out in 84% of the patients with gallbladder stones. Endoscopic bile duct lithotomy was feasible in 89% of patients with common bile duct stones. CONCLUSIONS Laparoscopic cholecystectomy was feasible for removing gallbladder stones after gastrectomy. Endoscopic bile duct lithotomy followed by laparoscopic cholecystectomy was a good option for patients in whom endoscopic intervention could be performed. On the other hand, choledochoenterostomy could be a good option for patients in whom endoscopic bile duct lithotomy cannot be performed, particularly considering the risk of recurrent bile duct stones.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) for management of bile duct stone (BDS) in patients with surgically altered anatomy is challenging even when applying enteroscopy. Endoscopic ultrasound-guided antegrade treatments (EUS-AG) for BDS have been developed but have not been well studied yet. The aim of the present study was to evaluate the feasibility and safety of EUS-AG for BDS in patients with surgically altered anatomy as a multicenter retrospective cohort study. METHODS A retrospective database analysis was performed to identify patients with surgically altered anatomy who underwent EUS-AG for the management of BDS at four academic care centers. Basic characteristics of the patients and details of the procedures were determined and the success rates and adverse event rates were evaluated. RESULTS EUS-AG for BDS was attempted in 29 patients. Successful BDS removal was achieved in 72% (21/29) of patients. Reasons for failed EUS-AG were unsuccessful bile duct puncture in six, unsuccessful guidewire manipulation in one, and unsuccessful stone removal using a retrieval balloon in one. Adverse events occurred in five (17%) but were successfully managed conservatively. CONCLUSION EUS-AG for BDS is a feasible and safe alternative in patients with surgically altered anatomy, although further evaluation and development of dedicated devices are needed.

Abstract
BACKGROUND Two-stage treatment involving stone removal after drainage is recommended for mild to moderate acute cholangitis associated with choledocholithiasis. However, single-stage treatment has some advantages. We aimed to assess the efficacy and safety of single-stage endoscopic treatment for mild to moderate acute cholangitis associated with choledocholithiasis. METHODS A multicenter, non-randomized, open-label, exploratory clinical trial was performed in 12 institutions. A total of 50 patients with a naïve papilla and a body temperature ≥37 °C who were diagnosed with mild to moderate cholangitis associated with choledocholithiasis were enrolled between August 2012 and February 2014. RESULTS Of the 50 patients, 15 had mild cholangitis and 35 had moderate cholangitis. The median number of common bile duct stones was 2 (range, 1-8), and the median diameter of the common bile duct stones was 7.5 mm (range, 1-18). The cure rate of acute cholangitis within 4 days after single-stage treatment was 90% (45/50) based on a body temperature <37 °C for ≥24 h. The incidence of complications was 10% (5/50). CONCLUSION Single-stage endoscopic treatment may be effective and safe for mild to moderate acute cholangitis associated with choledocholithiasis (clinical trial registration number: UMIN000008494).

Abstract
Cholangioscopy was first performed in the 1970s. We now use the term cholangiopancreatoscopy (CP) to reflect the wider application of these miniature reusable dual-operator "mother-daughter" endoscope systems and now fully disposable and digital single-operator optical catheters for evaluating the biliary or pancreatic duct. Cholangioscopy is an established modality for the management of large biliary stones and for the diagnosis and exclusion of biliary tumors. Pancreatoscopy is increasingly being performed to treat difficult pancreatic duct stones and may be used to distinguish malignant from benign ductal pathology. This review covers available CP technologies, indications, technique, efficacy, and complications.

Abstract
Recently, endoscopic ultrasonography (EUS)-guided transhepatic antegrade interventions have been introduced in patients with a surgically altered anatomy. Herein, we focused on and reviewed EUS-guided transhepatic antegrade stone removal (EUS-TASR) in patients with a surgically altered anatomy and native papilla. The basic technique of EUS-TASR involves the following steps: (1) EUS-guided needle puncture; (2) guidewire placement; (3) tract dilation; (4) balloon sphincteroplasty; (5) stone removal; and (6) stent placement if needed. Based on reports in the literature including our cases, the complete stone extraction rate is 71.4% (10/14) including five of our cases (60% success rate) at one session without serious complications. In conclusion, EUS-TASR appears to be feasible and useful in selected patients although its application may be limited depending on anatomical factors and current devices used.

Abstract
Endoscopic sphincterotomy (ES) is the standard therapy in common bile duct (CBD) stones extraction. Large stones (≥ 12 mm) or multiple stones extraction may be challenging after ES alone. Endoscopic sphincterotomy followed by large balloon dilation (ESLBD) has been described as an alternative to ES in these indications. Efficacy, safety, cost-effectiveness and technical aspects of the procedure have been here reviewed. PubMed and Google Scholar search resulted in forty-one articles dealing with CBD stone extraction with 12 mm or more dilation balloons after ES. ESLBD is at least as effective as ES, and reduces the need for additional mechanical lithotripsy. Adverse events rates are not statistically different after ESLBD compared to ES for pancreatitis, bleeding and perforation. However, particular attention should be paid in patients with CBD strictures, which is identified as a risk factor of perforation. ESLBD is slightly cost-effective compared to ES. A small sphincterotomy is usually performed, and may reduce bleeding rates compared to full sphincterotomy. Dilation is performed with 12-20 mm enteral balloons. Optimal inflation time is yet to be determined. The procedure can be performed safely even in patients with peri-ampullary diverticula and surgically altered anatomy. ESLBD is effective and safe in the removal of large CBD stones, however, small sphincterotomy might be preferred and CBD strictures should be considered as a relative contraindication.

Abstract
Recently, peroral direct cholangioscopy (PDCS) using an ultra-slim endoscope has come into the spotlight. However, the working channel is too small to use various devices for lithotripsy. We report a case of endoscopic lithotripsy with PDCS using a conventional endoscope as a cholangioscope. Computed tomography scan on an 80-year-old female who was admitted with acute cholangitis showed two large stones in the bile duct. Endoscopic retrograde cholangiopancreatography was attempted first. However, mechanical lithotripsy failed because the stone was too large for the basket catheter. Finally, electric hydraulic lithotripsy with PDCS using a conventional endoscope was performed allowed the stones to be cleared completely. In conclusion, PDCS using a conventional endoscope can be an alternative solution for endoscopic lithotripsy for patients with large stones in the dilated bile duct.

Abstract
BACKGROUND/AIMS Acute suppurative cholangitis (ASC), a severe form of acute cholangitis, is a life-threatening condition that must be treated with appropriate and timely management. The purpose of this study was to identify the factors that predispose patients to ASC. METHODS We retrospectively investigated 181 patients (100 men, 81 women; age, 70.66±7.38 years, mean±SD) who were admitted to Wonkwang University Hospital between January 2005 and June 2007 for acute cholangitis with common bile duct (CBD) stones. All patients underwent endoscopic retrograde cholangiopancreatogram to remove the stones. Variables and factors that could be assessed upon admission were analyzed to identify the risk factors for the development of ASC. RESULTS Of the 181 patients, 44 (24.3%) presented with ASC. On multivariate analysis, the followings were found to be independent risk factors for the development of ASC: impacted common bile duct stone (p=0.010), current smoker status (p=0.008), advanced age (>70 years; p=0.002), and gallstone (p=0.016). The most commonly isolated organisms in bile culture were Enterococcus species, Escherichia coli, and Klebsiella species. CONCLUSIONS Impacted bile-duct stones, current smoking, advanced age, and gallstones were identified as independent risk factors for the development of ASC in patients with CBD stones. These results suggest that emergency biliary drainage is beneficial in patients with these risk factors.

Abstract
AIM: To introduce a new method: small endoscopic sphincterotomy (ES) combined with endoscopic papillary large balloon dilation (SES + EPLBD) to treat patients with large biliary stones.
METHODS: Retrieval of large biliary stones was performed in 88 patients. Mean stone size was 14 ± 3 mm and mean number of stones was 2.5 ± 3.5. Firstly, ES with a small incision was performed. Next, endoscopic papillary dilation was performed with a large balloon to slowly match the size of the bile duct. Stones were then retrieved from the biliary duct with a balloon and a basket.
RESULTS: Stone retrieval was successful in all cases except one cystic duct stone case without the need to crush large stones. Mean procedure time was 30 ± 5 min. Dilating the papillary orifice with a large balloon made it possible to remove large stones smoothly without crushing them. After dilation with the large balloon, there were some instances of oozing, but no perforations. One instance of post-procedural pancreatitis (1%) occurred.
CONCLUSION: SES + EPLBD was effective for the retrieval of large biliary stones without the use of mechanical lithotripsy.
