Abstract
Limited endoscopic sphincterotomy (EST) combined with endoscopic papillary balloon dilation (EPBD) is widely used. However, the optimal duration of small balloon dilation in choledocholithiasis remains controversial. We aimed to determine the optimal duration for 10 mm diameter balloon dilation after limited EST in choledocholithiasis. In this randomized controlled clinical trial, 320 patients were randomly assigned to receive small balloon dilation (10 mm in diameter) for 1 min (n = 160) or 3 min (n = 160) after deep bile duct cannulation. No significant difference in success rate of stone extraction between the two groups was observed. The incidence of post-ERCP pancreatitis (PEP) was higher in the 1 min group (10.6%) than in the 3 min group (4.4%) (P = 0.034). The logistic regression analysis showed that guidewire into the pancreatic duct, cannulation time > 5 min and 1 min balloon dilation were independent risk factors for PEP. There were no significant differences in other post-ERCP adverse events such as acute cholangitis, bleeding, perforation, etc. between the two groups. In conclusion, 3 min in duration was determined to be the optimal dilation condition for the removal of common bile duct stones.

Abstract
BACKGROUND So far, there was no consensus regarding balloon dilation time in endoscopic papillary balloon dilation (EPBD). Thus, we conducted a systematic review and meta-analysis to compare the stone removal and overall complication rates of dilation of short and long duration with EPBD. METHODS The Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane Library), Web of Science, EMBASE Databases, and PubMed were searched from their inception to December 1, 2019 for all articles regarding balloon dilation time in EPBD for removal of bile duct stones. The data were extracted and the methodology quality was assessed. Meta-analysis was performed using RevMan5.3 software. RESULTS Four studies involving a total of 1553 patients were included, 918 in the short dilation group and 635 in the long dilation group. The results of meta-analysis showed that there was no significant difference between the 2 different dilation groups in the complete stone removal in randomized controlled trails (RCTs) group (P = .10) and non-RCTs group (P = 0.45), mechanical lithotripsy requirement (RCTs: P = .92; non-RCTs: P = .47), pancreatitis (RCTs: P = .48; non-RCTs: P = .45), bleeding (RCTs: P = .95; non-RCTs: P = .60), infection of biliary (RCTs: P = .58; non-RCTs: P = .29), perforation (RCTs: P = .32; non-RCTs: P = .37). CONCLUSION This systematic review suggests that there no significant difference in the efficacy and safety of dilation of short and long duration for removal of bile duct stones with EPBD.

Abstract
GOALS AND BACKGROUND Endoscopic retrograde cholangiopancreatography is widely utilized to diagnose and treat various pancreaticobiliary diseases, but postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) can be a fatal adverse event. Evidence suggests that statins may exhibit suppressive effects on inflammation in the pancreas. We carried out an observational cohort study to examine the protective effect of statins on PEP. STUDY We retrospectively identified consecutive patients who underwent endoscopic retrograde cholangiopancreatography at a tertiary care center in Japan between January 2010 and January 2019. The incidences of PEP were compared between regular and nonregular statin users. Using the multivariable logistic regression model, we examined the association of regular statin use with the incidence of PEP controlling for potential risk factors for PEP. RESULTS We included 2664 patients (328 regular statin users and 2336 nonregular users). The incidence of PEP did not differ by statin use status (P=0.52): 8.8% in regular statin users and 7.9% in nonregular users. The multivariable-adjusted odds ratio for PEP comparing regular statin use with nonregular use was 1.08 (95% confidence interval, 0.67-1.72; P=0.76). When we examined specific statin types (hydrophilic and lipophilic statins), we consistently observed the null association: 6.8% of 132 hydrophilic statin users and 10% of 196 lipophilic statin users (P=0.74 and 0.27, respectively, compared with nonregular users). CONCLUSIONS Regular statin use was not shown to be protective against PEP. A further investigation is warranted before this medication is tested in prospective randomized trials.

Abstract
Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) for patients with surgically altered anatomy is challenging. Recently, balloon endoscopy has been shown to facilitate ERCP for this population with a high technical success rate, but adverse events (AEs) are not uncommon. Compared to non-elderly patients, elderly patients may be at higher risk of AEs due to underlying comorbidities. The current study aimed to evaluate the feasibility of balloon endoscope-assisted ERCP (BE-ERCP) for the elderly. Patients and methods We retrospectively identified patients who underwent BE-ERCP between January 2010 and September 2019. For patients who underwent multiple procedures during the study period, the first session was analyzed. Early AEs associated with BE-ERCP were compared between elderly (≥ 75 years) and non-elderly patients. Results A total of 1,363 BE-ERCP procedures were performed, and 568 patients (211 elderly and 357 non-elderly) were included for the analyses. Technical success rates were high in both the elderly and non-elderly groups (80 % vs. 80 %, respectively). The rates of early AEs were similar between the groups (12 % vs. 9.0 % in the elderly and non-elderly group, respectively; P = 0.31). The mltivariable-adjusted odds ratio for early AEs comparing elderly to non-elderly patients was 1.36 (95 % confidence interval, 0.74-2.51; P = 0.32). Specifically, we did not observe between-group differences in rates of gastrointestinal perforation (2.4 % vs. 2.8 % in elderly and non-elderly groups, respectively; P = 0.99) and aspiration pneumonia (1.9 % vs. 0.6 %, P = 0.20). Conclusions BE-ERCP is a feasible procedure for elderly individuals with surgically altered anatomy.

Evaluation of the safety and efficacy of minimal endoscopic sphincterotomy followed by papillary balloon dilation for the removal of common bile duct stones. Saudi J Gastroenterol 2020; 26:290342. [PMID: 32719239 PMCID: PMC8019135 DOI: 10.4103/sjg.sjg_162_20] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 06/03/2020] [Accepted: 06/14/2020] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND/AIM A sufficiently open papilla is needed to remove common bile duct stones (CBDS) but endoscopic sphincterotomy (EST) requires a high level of skill and is difficult with endoscopic papillary balloon dilation (EPBD). The main adverse event of EST is bleeding and perforation and that of EPBD is post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. To reduce these adverse events we employed minimal EST followed by papillary dilation (ESBD), and retrospectively evaluated its efficacy and safety compared with EST. PATIENTS AND METHODS CBDS patients who underwent EST (n = 114) or ESBD (n = 321) at Juntendo University Hospital from January 2009 to December 2018 were consecutively enrolled, retrospectively. The exclusion criteria were large-balloon dilation (≥ 12 mm), large CBDS (>12 mm), and previous EST/EPBD. We compared the overall stone removal rate, incidence of adverse event, procedure time, number of ERCP procedures, and rate of mechanical lithotripsy (ML) between the two groups. RESULTS Complete stone removal was successful in both ESBD and EST group. However, the rate of multiple ERCP sessions was significantly lower (35.1% vs. 12.8%, P < 0.001), procedure time was shorter (31.6 vs. 25.8 min, P = 0.01), and rate of ML was lower (16.7% vs. 7.8%, P = 0.01) in ESBD group. Bleeding was significantly more frequent in the EST group (9.6% vs. 1.2%, P < 0.001), particularly acute bleeding (7.9% vs. 0.9%, P < 0.001). CONCLUSIONS ESBD is more efficient and safer in the management of CBD stones than EST. A prospective randomized study comparing ESBD with EST is needed to establish this combination technique.

Abstract
BACKGROUND Due to increasing opportunities for abdominal imaging studies, bile duct stones are occasionally diagnosed without any symptoms. However, there has been no consensus on the management of asymptomatic bile duct stones. We conducted a retrospective longitudinal cohort study to investigate the natural history of asymptomatic bile duct stones and clinical outcomes according to the timing of endoscopic removal. METHODS We identified consecutive patients who were diagnosed with asymptomatic common bile duct stones and categorized into those who were followed up with stones in situ (wait-and-see group) and those who received early endoscopic stone removal (intervention group). Cumulative incidence functions of biliary complications were estimated and compared between the groups. RESULTS We included 191 patients (114 patients in the wait-and-see group and 77 patients in the intervention group). In the wait-and-see group, the cumulative incidence of biliary complications was 6.1% at 1 year, 11% at 3 years, and 17% at 5 years. Asymptomatic disappearance of stones was observed in 22 patients (19%). Procedure-related adverse events of early endoscopic stone removal of asymptomatic stones were observed in 25 (32%) patients including 4 (5.2%) with severe pancreatitis. The cumulative incidence function of biliary complications did not differ by treatment strategies (P = 0.55). CONCLUSIONS Biliary complications occurred in a substantial proportion of patients with asymptomatic bile duct stones, but early endoscopic removal appeared to have little effect on the prevention of further biliary complications. Given the risk of procedure-related pancreatitis, the wait-and-see strategy may become a management option of asymptomatic stones.

Abstract
BACKGROUND AND AIM Recurrences after endoscopic treatment of common bile duct stones (CBDS) are common. The aims of this study were to identify risk factors for recurrences of CBDS and to evaluate the effect of interventions for prevention of further recurrences. METHODS A total of 976 patients who underwent endoscopic treatment of CBDS were retrospectively studied. Risk factors for single and multiple recurrent CBDS were evaluated using a Cox hazard regression model. The incidences of further recurrences were evaluated according to the additional interventions. RESULTS The mean age was 69.3 years, and 39.3% were female. Endoscopic papillary balloon dilation, endoscopic sphincterotomy, and endoscopic papillary large balloon dilation were performed in 858, 77, and 41 patients, respectively. The rates of one or more recurrence and multiple recurrences of CBDS were 12.4% and 2.7%, respectively. In the multivariate analyses, the significant risk factors were the bile duct size (hazard ratio [HR] 1.07, P = 0.012), gallbladder left in situ with stones (HR 1.91, P = 0.046), and pneumobilia after treatment (HR 2.10, P = 0.047) for single recurrence and the number of stones at the first recurrence (HR 1.16, P = 0.021) for multiple recurrences. In five out of nine cases with multiple recurrences, further recurrence was not observed after additional sphincteroplasty in addition to cholecystectomy. CONCLUSIONS The incidence of multiple recurrences was not uncommon after the first recurrence of CBDS.

Abstract
BACKGROUND Endoscopic sphincterotomy is the established treatment for common bile duct stones. Balloon dilation offers an alternative. Prolonged dilation (300 s) with a 10 mm diameter balloon decreases the occurrence of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). We aimed to determine the optimal duration of dilation for combined endoscopic sphincterotomy and balloon dilation for the removal of common bile duct stones. METHODS We did a multicentre, single-blinded, randomised controlled trial at 15 tertiary surgical centres in China. Eligible patients (≥18 years) with native papilla and common bile duct stones (≤1·5 cm in size and <2 cm in diameter) undergoing ERCP were randomly assigned (1:1:1:1:1) to receive balloon dilation for 0, 30, 60, 180, or 300 s after deep bile duct cannulation. Randomisation was done by an independent statistician using a computer-generated randomisation list with a block size of ten, stratified by centre. Patients and outcome assessors, but not endoscopists and investigators, were masked to treatment allocation. Balloon dilation was done with controlled radial expansion balloons according to common bile duct stone size. Stones were removed using stone retrieval balloons or baskets. The primary endpoint was overall frequency of post-ERCP pancreatitis. The primary efficacy analysis and safety analyses were done in the modified intention-to-treat population, which included all randomly assigned patients with successful cannulation, but excluded those who withdrew consent after randomisation. This study was registered with ClinicalTrials.gov, number NCT02510495, and is complete. FINDINGS Between July 29, 2015, and Dec 1, 2017, 3721 consecutive patients with common bile duct stones were recruited, 1718 of whom were excluded. The remaining 2003 patients underwent a small (3-5 mm) endoscopic sphincterotomy. 83 patients withdrew consent after the ERCP procedure, thus 1920 patients were included in the modified intention-to-treat analysis (0 s [n=371], 30 s [n=384], 60 s [n=388], 180 s [n=390], and 300 s [n=387]). Overall, post-ERCP pancreatitis occurred in 199 (10%) of 1920 patients (44 [12%] patients in the 0 s group, 28 [7%] in the 30 s group, 32 [8%] in the 60 s group, 36 [9%] in the 180 s group, and 59 [15%] in the 300 s group). Prolonged dilation (300 s) significantly increased the occurrence of post-ERCP pancreatitis compared with shorter balloon dilation (p=0·002). The frequency of post-ERCP pancreatitis was significantly lower in the 30, 60, and 180 s groups than in the 300 s group (relative risk [RR] 0·48, 95% CI 0·31-0·73; p=0·0005 vs the 30 s group; 0·54, 0·36-0·81; p=0·003 vs the 60 s group; 0·61, 0·41-0·89; p=0·01 vs the 180 s group). The frequency of post-ERCP pancreatitis was significantly higher in the 0 s group than the 30 s group (RR 1·62, 1·04-2·56; p=0·03). No difference in stone extraction (all ≥90%) was observed between groups. Following ERCP, 90 (5%) of 1920 patients had acute cholangitis, 14 (<1%) had acute cholecystitis, and five (<1%) had gastrointestinal bleeding, with no significant differences between groups. One (<1%) patient had Stapfer II perforation, which resolved spontaneously with conservative treatment. INTERPRETATION A balloon dilation time of 30 s for combined endoscopic sphincterotomy and balloon dilation reduced the frequency of post-ERCP pancreatitis and was determined to be the optimum dilation time for the removal of common bile duct stones.

Endoscopic papillary large balloon dilation and endoscopic papillary balloon dilation both without sphincterotomy for removal of large bile duct stones: A propensity-matched analysis. Dig Endosc 2019; 31:59-68. [PMID: 29943385 DOI: 10.1111/den.13220] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Accepted: 06/22/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND AND AIM Endoscopic papillary large balloon dilation (EPLBD) without endoscopic sphincterotomy (EST) may facilitate extraction of large bile duct stones through achieving adequate dilation of the ampulla. However, contrary to favorable long-term outcomes after endoscopic papillary balloon dilation (EPBD), that of EPLBD without EST has been little investigated. Therefore, we conducted the current study to evaluate short- and long-term outcomes of EPLBD without EST and EPBD after removal of large bile duct stones (LBDS; ≥10 mm). METHODS This retrospective study included patients without a previous history of EST, EPBD or EPLBD who underwent EPLBD without EST or EPBD for removal of LBDS. Each patient in the EPLBD without EST group was matched to a patient in the EPBD group using propensity scores. RESULTS Forty-four patients in each group were matched for the analysis. Baseline characteristics were balanced after propensity matching. Rate of complete stone removal in a single session was higher (80% vs 16%, P < 0.001), number of ERCP sessions (1.3 ± 0.7 vs 2.4 ± 1.5, P < 0.001) and rate of lithotripsy use (30% vs 80%, P < 0.001) were smaller in the matched EPLBD without EST group. Contrary to null between-group differences in early adverse events (P = 0.99), a cumulative rate of late biliary complications was higher in the EPLBD without EST group (P = 0.02). CONCLUSION EPLBD without EST showed higher efficacy for removal of LBDS but was associated with worse long-term outcomes when compared to EPBD.

Abstract
AIM To evaluate the efficacy of endoscopic papillary balloon dilatation (EPBD) combined with endoscopic sphincterotomy (EST) in the treatment of common bile duct stones and to identify the factors affecting the recurrence of stones.
METHODS One hundred patients with choledocholithiasis who underwent endoscopic retrograde cholangiopancreatography (ERCP) at our hospital between January 2014 and January 2016 were randomly divided into a control group and an experimental group. The patients in the control group and experimental group were given EST lithotomy and small-incision endoscopic sphincterotomy (SEST) combined with EPBD, respectively. The one-time success rate, total success rate, and the incidence of complications after ERCP were comparatively analyzed. The Kaplan-Meier survival curve of patients with postoperative stone recurrence was plotted, and the Cox regression model was used to explore the risk factors for postoperative recurrence in patients.
RESULTS The maximum diameter of the stones (t = -1.055, P = 0.294), the rate of multiple stones (χ2 = 0.644, P = 0.422), the maximum diameter of bile duct (t = -0.820, P = 0.414), and the stone removal success rate (94.0% and 100.0%, χ2 = 1.375, P = 0.241) differed significantly between the control group and the experimental group. There was no significant difference in the one-time success rate between the control group and the experimental group (84.0% and 96.0%, χ2 = 4.332, P = 0.037). The incidence of complications after ERCP in the control group and experimental group was 17.02% and 6.0%, respectively (χ2 = 4.337, P = 0.036). A total of 97 patients were followed, with stone recurrence occurring in 11 cases. In the 97 patients followed, the incidence of complications after ERCP in the control group and experimental group was 17.02% and 6.0%, respectively (χ2 = 2.927, P = 0.087). Log-rank test showed that the risk of gallstone recurrence in the experimental group was significantly lower than that in the control group (HR = 0.285, 95%CI: 0.095-0.888, P = 0.044). Multivariate Cox regression analysis showed that multiple endoscopic procedures, common bile duct angulation (≤ 145°), and EST were risk factors for ERCP recurrence.
CONCLUSION The success rate and safety of EPBD combined with LEST in the management of common bile duct stones are high, and the risk of long-term stone recurrence is low. Multiple endoscopic operations and common bile duct angulation (≤ 145°) are risk factors for stone recurrence.
