RESUMO
INTRODUCTION: Evidence for the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) between a basket catheter and a balloon catheter for endoscopic common bile duct stone (CBDS) removal is lacking. This study aimed to compare ERCP outcomes using a basket catheter and a balloon catheter for endoscopic CBDS removal. METHODS: This multicenter retrospective study included 904 consecutive patients with native papilla who underwent endoscopic stone removal for CBDS ≤10 mm using a basket catheter and/or a balloon catheter at three institutions in Japan. ERCP outcomes between the basket and balloon groups were compared using inverse probability of treatment weighting (IPTW) method. RESULTS: ERCP-related adverse events occurred in 6.5% (29/449) and 7.7% (35/455) of patients in the basket and balloon groups, respectively (IPTW-adjusted p = 0.52). The incidences of post-ERCP pancreatitis, cholangitis, and perforation were similar in the basket and balloon groups (3.8% vs. 2.9%, 1.3% vs. 0.9%, and 0.7% vs. 0.7%, respectively). However, bleeding incidences were significantly higher in the balloon group than in the basket group (3.3% vs. 0.7%, IPTW-adjusted p = 0.012). Successful complete stone removal at one ERCP session using a single catheter was achieved in 17.8% (80/449) in the basket group and in 81.3% (370/455) in the balloon group (IPTW-adjusted p < 0.001). DISCUSSION: A balloon catheter is more likely to complete stone extraction for CBDS ≤10 mm with a single catheter at one endoscopic stone removal session. However, the risk for post-ERCP bleeding is higher in the balloon group than in the basket group.

INTRODUCTION: In acute obstructive common bile duct (CBD) stones endoscopic retrograde cholangiography for CBD stone removal before cholecystectomy (ChE) ('ERC-first') is the gold standard of treatment. Intraoperative antegrade balloon dilatation of the duodenal papilla during ChE with flushing of CBD stones to the duodenum ('ABD-during-ChE') may be an alternative 'one-stop-shop' treatment option. However, a comparison of outcomes of the 'ABD-during-ChE' technique and the'ERC-first' approach has never been performed. METHODS: Retrospective case control matched study of patients suffering from obstructive CBD stones (< 8 mm) without severe pancreatitis or cholangitis that underwent the traditional 'ERC-first' approach versus the 'ABD-during-ChE' technique. Primary endpoint was the overall Comprehensive Complication Index (CCI®) from diagnosis to complete CBD stone removal and performed ChE. RESULTS: A total of 70 patients were included (35 patients each in the 'ERC first'- and 'ABD-during-ChE'-group). There were no statistical significant differences in terms of demographics and disease specific characteristics between the two study groups. However, there was a not significant difference towards an increased overall CCI® in the 'ERC-first' group versus the 'ABD-during-ChE' group (14.4 ± 15.4 versus 9.8 ± 11.1, p = 0.225). Of note, six major complications (Clavien-Dindo classification ≥ IIIa) occurred in the 'ERC-first' group versus two in the 'ABD-during-ChE' group (17% versus 6%, p = 0.136). In addition, significantly more interventions and a longer overall time from diagnosis to complete clearance of bile ducts and performed ChE was found, when comparing the 'ERC-first' group and the 'ABD-during-ChE' group (3.7 ± 0.8 versus 1.1 ± 0.4, p < 0.001; 160.5 ± 228.6 days versus 12.0 ± 18.0 days, p < 0.001). CONCLUSION: In patients suffering from acute obstructive CBD stones smaller than 8 mm, compared to the 'ERC-first' approach, the 'ABD-during-ChE' technique resulted in significantly less interventions and reduced overall treatment time from diagnosis to complete clearance of bile ducts and performed ChE. This comes together with a strong trend of less intervention related complications in the 'ABD-during-ChE' group.

Tauroursodeoxycholic acid (TUDCA) can activate farnesoid X receptor (FXR) to involve in the formation of gallstones. Here, this study aimed to probe the potential mechanism of TUDCA-FXR network in the formation of bile duct stone. The levels of TUDCA, FXR and NCK1 were decreased, while the level of miR-107 was increased in the serum of bile duct stone patients. FXR expression was positively correlated with TUDCA or NCK1 expression in patients, moreover, TUDCA pretreatment in biliary epithelial cells increased the levels of FXR and NCK1, and rescued the decrease of NCK1 caused by FXR knockdown in cells. Then functional analysis showed FXR knockdown caused apoptosis and endoplasmic reticulum stress (ERS) as well as suppressed proliferation in biliary epithelial cells in vitro, which were attenuated by TUDCA pretreatment or NCK1 overexpression Mechanistically, NCK1 was a target of miR-107, which was up-regulated by FXR silencing, and FXR knockdown-induced decrease of NCK1 was rescued by miR-107 inhibition. Additionally, miR-107 expression was negatively correlated with TUDCA expression in bile duct stone patients, and TUDCA pretreatment in biliary epithelial cells decreased miR-107 expression by FXR. Functionally, the pretreatment of TUDCA or FXR agonist suppressed miR-107-evoked apoptosis and ERS in biliary epithelial cells. In conclusion, TUDCA up-regulates FXR expression to activate NCK1 through absorbing miR-107, thus suppressing the apoptosis and ERS in biliary epithelial cells, these results provided a theoretical basis for elucidating the mechanism of bile duct stone formation.
RESUMO
Acute cholangitis (AC) is a biliary tract infection with in-hospital mortality rates reaching up to 14.7%. The underlying condition is biliary obstruction caused by benign and malignant etiologies, as well as bacteriobilia, with commom bile duct (CBD) stone being one of the most common causes. Currently, the diagnosis is validated using Tokyo Guidelines 2018 criteria. Acute cholangitis due to CBD stone should be managed in a comprehensive manner, i.e., periendoscopic care continuum, consisting of pre-endoscopic care, endoscopic management, and post-endoscopic care. Pre-endoscopic care is primarily comprised of supportive therapy, antibiotic administration, optimal timing of endoscopic retrograde cholangiopancreatography (ERCP), pre-ERCP preparation, and informed consent. Endoscopic management is biliary decompression with stone extraction facilitated via ERCP procedure. Selective biliary cannulation should be performed meticulously. Bile aspiration and minimal bile duct contrast injection should be done to minimize the worsening of biliary infection. Endoscopic biliary sphincterotomy, endoscopic papillary balloon dilatation, and/or endoscopic papillary large balloon dilatation are all safe procedures that can be used in AC. Special precautions must be undertaken in critical and severe acute cholangitis patients who may not tolerate bleeding, in whom endoscopic biliary sphincterotomy may be postponed to decrease the risk of bleeding, and biliary decompression may be only attempted without CBD stone extraction. Nasobiliary tubes and plastic biliary stents are equally effective and safe for patients who have only undergone biliary decompression. In post-endoscopic care, management of adverse events and observation of therapy response are mandatory.

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.

BACKGROUND: Existing guidelines for predicting common bile duct stones (CBDS) are not specific for acute calculous cholecystitis (ACC). This paper is a posthoc analysis of the S.P.Ri.M.A.C.C study aiming to prospectively validate on a large independent cohort of patients the Israeli Score (IS) in predicting CBDS in patients with ACC. METHODS: The S.P.Ri.M.A.C.C. study is an observational multicenter prospective study endorsed by the World Society of Emergency Surgery (WSES). Between September 1st, 2021, and September 1st, 2022, 1201 participants were included. The Chi-Square test was used to compare categorical data. A Cochran-Armitage test was run to determine whether a linear trend existed between the IS and the presence of CBDS. To assess the accuracy of the prediction model, the receiver operating characteristic (ROC) curve was generated, and the area under the ROC curve (AUC) was calculated. Logistic regression was run to obtain Odds Ratio (OR). A two-tailed p < 0.05 was considered statistically significant. RESULTS: The rate of CBDS was 1.8% in patients with an IS of 0, 4.2% in patients with an IS of 1, 24.5% in patients with 2 and 56.3% in patients with 3 (p < 0.001). The Cochran-Armitage test of trend showed a statistically significant linear trend, p < 0.001. Patients with an IS of 3 had 64.4 times (95% CI 24.8-166.9) higher odds of having associated CBDS than patients with an IS of 0. The AUC of the ROC curve of IS for the prediction of CBDS was 0.809 (95% CI 0.752-0.865, p < 0.001). By applying the highest cut-off point (3), the specificity reached 99%, while using the lowest cut-off value (0), the sensitivity reached 100%. CONCLUSION: The IS is a reliable tool to predict CBDS associated with ACC. The algorithm derived from the IS could optimize the management of patients with ACC.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a major option for common bile duct (CBD) stones. Endoscopic sphincterotomy (EST), endoscopic papillary balloon dilatation (EPBD), and endoscopic sphincterotomy plus balloon dilatation (ESBD) are procedures for opening the bile duct orifice to extract CBD stones during ERCP. The optimal method for extracting small CBD stones (≤ 10 mm) has not yet been proposed. We aimed to compare the efficacy and safety of these three techniques in extracting small CBD stones. METHODS: ERCP for small stones was performed between January 2009 and November 2020 at three tertiary care centers. The incidence of post-ERCP pancreatitis (PEP) was compared among EST, EPBD, and ESBD groups. First and overall success rates of stone extraction, utilization rate of mechanical lithotripsy, and other ERCP complications such as bleeding, perforation, infection, and hyperamylasemia were compared. RESULTS: A total of 2181 patients were enrolled between January 2009 and November 2020. The proportion of young patients (≤ 45 years) in EPBD group was more than those in EST and ESBD group. Stone size in ESBD group was much larger than EST and EPBD group. After propensity score matching, the success rates of first and overall stone extraction in the three groups were high, and the rates of mechanical lithotripsy were low, with no significant difference. The PEP incidences showed no differences among the three groups. The incidence of bleeding complication in EST group was higher than that in EPBD group. No significant differences were observed in other complications between EPBD group and ESBD group. ESBD group had higher incidence of overall, infection, and hyperamylasemia complications than EST group. CONCLUSION: EPBD is equivalent to ESBD in stone removal efficiency and complication rate, but brings a lower bleeding risk than EST. Therefore, we recommend EPBD as the first choice for small CBD stones.

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 were 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.

BACKGROUND: The treatment of common bile duct (CBD) stones with minimally invasive surgery (MIS) is more technical demanding than laparoscopic cholecystectomy (LC), especially in patients with history of previous abdominal surgery, cholangitis or cholecystitis. Near-infrared (NIR) cholangiography via systemic or biliary tree administration of indocyanine green (ICG), which enhances the visualization of the biliary tree anatomy, may increase the reassurance of CBD localization. The aim of this study was to identify the benefit of near-infrared cholangiography for laparoscopic common bile duct exploration (LCBDE). METHODS: Three groups of CBD stone patients were included in this retrospective study depending on the surgical methods: 1) open choledocholithotomy (OCC), 2) laparoscopic choledocholithotomy (LCC), and 3) near-infrared cholangiography-assisted laparoscopic choledocholithotomy (NIR-CC). For the NIR-CC group, either 3 ml (concentration: 2.5 mg/mL) of ICG were intravenously administered or 10 ml (concentration: 0.125 mg/mL) of ICG were injected directly into the biliary tree. The enhancement rate of the cystic duct (CD), CBD, the upper and lower margin of the CBD were compared using white light image. RESULTS: A total of 187 patients with a mean age of 68.3 years were included (OCC, n = 56; LCC, n = 110; NIR-CC, n = 21). The rate of previous abdominal surgery was significantly lower in the LCC group. The conversion rate was similar between the LCC and the NIR CC groups (p = 0.746). The postoperative hospital stay was significantly longer in the OCC group. No differences in morbidity and mortality were found between the three groups. In the NIR-CC group, the localization of CBD was as high as 85% compared to 24% with white light imaging. CONCLUSIONS: Near-infrared cholangiography helps increase the chance of success in minimally invasive approaches to CBD stones even in patients with previous abdominal surgeries, without increasing the rate of conversion.

Endoscopic management of biliary diseases in patients with surgically altered anatomy can be challenging because the altered anatomy makes it difficult to insert an endoscope into the biliary orifice. Even if insertion is feasible, the worse maneuverability of the endoscope and the restriction in available devices and techniques could complicate the procedure. Recently, endoscopic ultrasound-guided antegrade intervention (EUS-AG) has been reported as a useful management method for biliary diseases, especially in patients with surgically altered anatomy. In EUS-AG, the biliary disease is managed in an antegrade fashion through a temporal fistula created under EUS guidance between the intrahepatic biliary duct and upper intestine. In this article, we reviewed the current status of EUS-AG for each biliary diseases, malignant biliary obstruction, bile duct stones, and benign biliary stricture in patients with surgically altered anatomy.

OBJECTIVES: We aimed to determine whether inflammatory indexes (II), including the neutrophil-lymphocyte ratio (NLR), the C-reactive protein (CRP) to albumin ratio (CAR), the CRP-lymphocyte ratio (CLR), and the systemic immune-inflammation index (SIII) can be diagnostic for common bile duct stones (CBDSs) excretion before endoscopic retrograde cholangiopancreatography (ERCP). BACKGROUNDS: Because of the spontaneous clearance, it is mandatory to ascertain the presence of CBDSs before ERCP. METHODS: Retrospectively, we evaluated two groups. Group A included 96 records in which CBDSs existed in magnetic resonance cholangiopancreatography (MRCP) and ERCP. Group B included 36 records in which CBDSs existed in MRCP but not ERCP. IIs were calculated on presentation and before ERCP. RESULTS: Stone detection in ERCP had a 3.992-fold (95% 1.769-9.007) higher probability with a stone larger than 3.25â mm in MRCP. Before ERCP, CAR, and CLR values were higher in group A than in group B (3.88 [1.25-14.14] and 1.24 [0.50-9.66], p = 0.027 versus 8.79 [2.19-35] and 2.67 [1.02-20.05], p = 0.029, respectively). Higher CRP, CAR, and CLR values were considered significant for detecting a stone in ERCP (AUC: 0.627 [0.519-0.739], 0.625 [0.513-0.737], and 0.624 [0.514-0.734], respectively). CONCLUSION: Low CRP, CAR, and CLR values might associate with the spontaneous migration of CBDS.

Background and objectives: The safety of electrohydraulic lithotripsy (EHL) in older adults remains unclear. We aimed to investigate the efficacy and safety of EHL using peroral cholangioscopy (POCS) under endoscopic retrograde cholangiopancreatography (ERCP) guidance in older adults aged ≥80 years. Materials and Methods: This retrospective clinical study was conducted at a single center. Fifty patients with common bile duct stones who underwent EHL using POCS under ERCP guidance at our institution, between April 2017 and September 2022, were enrolled in this study. The eligible patients were divided into an elderly group (n = 21, age ≥80 years) and a non-elderly group (n = 29, age ≤79 years), and were analyzed. Results: A total of 33 and 40 EHL procedures were performed in the elderly and non-elderly groups, respectively. After excluding cases in which stone removal was performed at other institutions, complete removal of common bile duct stones was confirmed in 93.8% and 100% of the elderly and non-elderly groups, respectively (p = 0.20). The mean number of ERCPs required for complete removal of bile duct stones was 2.9 and 4.3 in the elderly and non-elderly groups, respectively (p = 0.17). In the EHL session, the overall occurrence of adverse events was eight and seven in the elderly (24.2%) and non-elderly (17.5%) groups, respectively; however, the difference was insignificant (p = 0.48). Conclusions: EHL using POCS under ERCP guidance is effective in patients aged ≥80 years and there was no significant increase in adverse event rates compared to those aged ≤79 years.

BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy with poor prognosis. Intrahepatic bile duct stone (IBDS) is one of the key causes to ICC occurrence and can increase morbidity rate of ICC about forty times. However, the specific carcinogenesis of IBDS is still far from clarified. Insight into the metabolic phenotype difference between IBDS and ICC can provide potential mechanisms and therapeutic targets, which is expected to inhibit the carcinogenesis of IBDS and improve the prognosis of ICC. METHODS: A total of 34 participants including 25 ICC patients and 9 IBDS patients were recruited. Baseline information inclusive of liver function indicators, tumor biomarkers, surgery condition and constitution parameters etc. from patients were recorded. ICC and IBDS pathological tissues, as well as ICC para-carcinoma tissues, were collected for GC-MS based metabolomics experiments. Multivariate analysis was performed to find differentially expressed metabolites and differentially enriched metabolic pathways. Spearman correlation analysis was then used to construct correlation network between key metabolite and baseline information of patients. RESULTS: The IBDS tissue and para-carcinoma tissue have blurred metabolic phenotypic differences, but both of them essentially distinguished from carcinoma tissue of ICC. Metabolic differences between IBDS and ICC were enriched in linoleic acid metabolism pathway, and the level of 9,12-octadecadienoic acid in IBDS tissues was almost two times higher than in ICC pathological tissues. The correlation between 9,12-octadecadienoic acid level and baseline information of patients demonstrated that 9,12-octadecadienoic acid level in pathological tissue was negative correlation with gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP) level in peripheral blood. These two indicators were all cancerization marker for hepatic carcinoma and disease characteristic of IBDS. CONCLUSION: Long-term monitoring of metabolites from linoleic acid metabolism pathway and protein indicators of liver function in IBDS patients has important guiding significance for the monitoring of IBDS carcinogenesis. Meanwhile, further insight into the causal relationship between linoleic acid pathway disturbance and changes in liver function can provide important therapeutic targets for both IBDS and ICC.

BACKGROUND AND AIM: Choledocholithiasis is the most common indication for endoscopic retrograde cholangiopancreatography (ERCP). Identifying risk factors for post-ERCP pancreatitis (PEP) is important for reducing the risk of developing PEP after common bile duct (CBD) stone removal. However, studies examining the risk factors for PEP for CBD stones are scarce. The aim of this study was to examine whether the presence or absence of acute cholangitis is a clinical risk factor for PEP in patients with CBD stones. METHODS: In this multicenter retrospective study, 1539 patients with naïve papillae were divided into patients without and with acute cholangitis. We compared the incidence of PEP between the two groups using one-to-one propensity score matching to adjust for the potential confounding factors of PEP. RESULTS: In the entire cohort, the rates of PEP in patients without and with acute cholangitis were 9.6% (52/542) and 1.8% (18/997), respectively (P < 0.001, odds ratio = 5.8). In the propensity-matched cohort, the rates of PEP in patients without and with acute cholangitis were 8.3% (27/326) and 2.5% (8/326), respectively (P = 0.002, odds ratio = 3.6). The rate of PEP was significantly higher in patients without acute cholangitis than in those with acute cholangitis after adjusting for the confounding factors of PEP. CONCLUSIONS: The absence of acute cholangitis may be an important clinical risk factor for PEP due to CBD stone removal. In patients without acute cholangitis, endoscopists should explain the specific risk of PEP carefully and actively implement prophylaxis against PEP.

BACKGROUND/AIMS: Residual common bile duct (CBD) stones occasionally become symptomatic after stone removal with endoscopic retrograde cholangiopancreatography (ERCP) upon removal of the endoscopic biliary stent (EBS). An accurate evaluation of residual stones before stent removal is necessary. This study evaluated a new two-step check method using endoscopic ultrasound (EUS) for the detection of residual stones after ERCP stone removal. METHODS: Fifty-six patients who underwent CBD stone removal and EBS placement were prospectively enrolled. Residual stones were evaluated by the check method. EBS was removed at the time of the check method or at a later time of residual stone removal. The primary outcome was to evaluate the efficacy of this check method. RESULTS: Residual CBD stone/sludge was detected in 20 of 56 patients (35.7%; stones: 28.6%, sludge: 7.1%) by the check method and removed by the ERCP procedure at a later time. After stent and final stone removal, patients were followed for an average of 211 days; cholangitis recurred in only 1.8% of patients. There were no adverse events associated with the check method. Temporary EBS prevented the recurrence of cholangitis by residual stone and caused no adverse events in the pancreatobiliary tract until the two-step check method (median, 113 days; range, 17-232 days). CONCLUSION: The new check method may be ideal and feasible for EBS removal because recurrences are very rare when a clear CBD has been verified, and an additional ERCP procedure is also possibly avoided.

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.

BACKGROUND: Common bile duct stones (CBDSs) occasionally cause serious diseases, and endoscopic extraction is the standard procedure for CBDS. To prevent biliary complications, cholecystectomy is recommended for patients who present with gallbladder (GB) stones after endoscopic CBDS extraction. However, CBDS can occasionally recur. To date, the occurrence of CBDS after endoscopic CBDS extraction and subsequent cholecystectomy is not fully understood. Hence, the current study aimed to evaluate the incidence of postoperative CBDSs. METHODS: This retrospective observational study included consecutive patients who underwent postoperative endoscopic retrograde cholangiography after endoscopic CBDS extraction and subsequent cholecystectomy between April 2012 and June 2021 at our institution. After endoscopic CBDS extraction, a biliary plastic stent was inserted to prevent obstructive cholangitis. Endoscopic retrograde cholangiography was performed to evaluate postoperative CBDSs after cholecystectomy until hospital discharge. The outcomes were the incidence of postoperative CBDSs and CBDSs/sludge. Moreover, the predictive factors for postoperative CBDSs were evaluated via univariate and multivariate analyses. RESULTS: Of eligible 204 patients, 52 patients (25.5%) presented with postoperative CBDSs. The incidence rate of CBDS/sludge was 36.8% (n = 75). Based on the univariate analysis, the significant predictive factors for postoperative CBDSs were ≥ 6 CBDSs, presence of cystic duct stones, and ≥ 10 GB stones (P < 0.05). Moreover, male sex and < 60-mm minor axis in GB might be predictive factors (P < 0.10). Based on the multivariate analysis, ≥ 6 CBDSs (odds ratio = 6.65, P < 0.01), presence of cystic duct stones (odds ratio = 4.39, P < 0.01), and ≥ 10 GB stones (odds ratio = 2.55, P = 0.01) were independent predictive factors for postoperative CBDSs. CONCLUSIONS: The incidence of postoperative CBDS was relatively high. Hence, patients with predictive factors for postoperative CBDS must undergo imaging tests or additional endoscopic procedure after cholecystectomy.

BACKGROUND: Routine use of intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) for detecting common bile duct stones remains controversial. The 2016 World Society of Emergency Surgery (WSES) guidelines on acute calculous cholecystitis proposed a risk stratification for choledocholithiasis. Our present study aimed to (1) examine the findings of common bile duct (CBD) stones in patients underwent LC with routine use of IOC, and (2) validate the 2016 WSES risk classes for predicting choledocholithiasis. METHODS: All patients had LC with IOC routinely performed from November 2012 to December 2017 were reviewed retrospectively. Patients were classified into high-, intermediate-, and low-risk groups based on the 2016 WSES risk classes with modification. RESULTS: A total of 990 patients with LC and routine IOC were enrolled. CBD stones were detected in 197 (19.9%) patients. The rate of CBD stone detected in low-, intermediate-, high-risk groups were 0%, 14.2%, and 89.6%, respectively. Predictors as following: evidence of CBD stones on abdominal ultrasound or computed tomography, CBD diameter > 6 mm, total bilirubin > 4 mg/dL, bilirubin level = 1.8-4 mg/dL, abnormal liver biochemical test result other than bilirubin, presence of clinical gallstone pancreatitis had statistical significance between patients with and without CBD stones. Major bile duct injury was found in 4 patients (0.4%). All 4 patients had uneventful recovery after repair surgery. CONCLUSIONS: Based on our study results, the 2016 WSES risk classes for choledocholithiasis could be an effective approach for predicting the risk of choledocholithiasis. Considering its advantages for detecting CBD stones and biliary injuries, the routine use of IOC is still suggested.

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.

BACKGROUND: Patients with suspected choledocholithiasis (CDL) are stratified as high-risk (HR), intermediate-risk (IR), and low-risk (LR) according to the guidelines of Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), American Society for Gastrointestinal Endoscopy (ASGE), and European Society of Gastrointestinal Endoscopy (ESGE). Although these approaches are invaluable, paucity of validation studies are currently available. This study aimed to evaluate the diagnostic accuracy of the above risk stratification criteria in predicting CDL. METHODS: We conducted a retrospective cohort study of 280 patients with suspected CDL. All patients were stratified according to above professional societies as HR, IR, and LR, and diagnostic performance was evaluated. RESULTS: In the HR group, area under the receiver operating characteristic curve (AUC) were 0.77 [95% confidence interval (CI), 0.70-0.84], 0.75 (95% CI, 0.68-0.81), and 0.74 (95% CI, 0.68-0.81) for SAGES, ASGE, and ESGE criteria, respectively. The diagnostic accuracy were 78.93% (81.13% sensitivity, 72.06% specificity), 75% (75.47% sensitivity, 73.53% specificity), and 70% (66.04% sensitivity, 82.35% specificity) for SAGES, ASGE, and ESGE criteria, respectively. Regarding the IR group, the diagnostic accuracy were 22.50% (16.98% sensitivity, 39.71% specificity), 25% (24.53% sensitivity, 26.47% specificity), and 30.00% (33.49% sensitivity, 19.12% specificity) for SAGES, ASGE, and ESGE criteria, respectively. The common bile duct stone (CBDS) visualized on imaging has the highest risk for CDL [odds ratio (OR), 13.59 (95% CI, 5.26-35.12)], followed by CBDS plus dilated common bile duct [OR, 13.33 (95% CI, 5.16-34.47)], CBDS plus cholangitis [OR, 13.33 (95% CI, 3.17-56.15)], and CBDS plus total bilirubin level > 1.7 mg/dL [OR, 9.89 (95% CI, 3.47-28.20)]. CONCLUSIONS: The current SAGES, ASGE, and ESGE criteria have acceptable diagnostic accuracy for CDL. The patients with visualized CBDS on imaging have the highest risk for CDL.
