Project description:BackgroundStone recurrence is a significant complication following endoscopic bile duct clearance. Endoscopic papillary large-balloon dilation (EPLBD) with biliary sphincterotomy (EBS) has shown satisfactory results in preventing recurrence of "large" common bile duct stones (CBDS). However, data on outcomes after EPLBD+EBS for CBDS ≤12 mm remain scarce. The present study prospectively evaluated the mid- and long-term efficacy of EPLBD+EBS for CBDS recurrence among this group of patients.MethodsConsecutive patients with CBDS ranging from 8-12 mm, treated with EPLBD+EBS from June 2018 through June 2020, were prospectively followed-up for at least 36 months. CBDS recurrence was defined as recurrent stones confirmed by endoscopic retrograde cholangiopancreatography (ERCP) during the follow-up period.ResultsOverall, 72 patients (mean age: 67 years, 52.8% male) were included, of whom 22 (30.5%) had multiple (≥3) CBDS, 23 (31.9%) had a history of cholecystectomy, 13 (18.1%) had a periampullary diverticulum and 22 (30.5%) had a previous EBS. The mean CBD diameter was 11.6±1 mm, while a tapered duct was noted in 7 (9.7%). Post-procedural bleeding and cholangitis occurred in 1 and 2 cases respectively. No cases of perforation and post-ERCP pancreatitis were observed. During a mean follow up of 46.4±6.2 months (range 37-60), no mid-term recurrence was observed, whereas CBDS recurred in 2/72 (2.7%) in the long term.ConclusionsEPLBD+EBS in patients with CBDS ≤12 mm was associated with a very low rate of mid- and long-term CBDS recurrence. Our results need to be further investigated with randomized controlled trials.

Project description:BackgroundTo assess the short-term outcomes after endoscopic sphincterotomy (EST) plus endoscopic papillary balloon dilation (EPBD) versus EPBD alone and appropriate balloon dilation time in EPBD alone.Materials and methodsA total of 413 patients with common bile duct stones (CBDSs) were included in the EST plus EPBD group and 84 were in the EPBD alone group. We retrospectively evaluated the safety and efficacy between EST plus EPBD and EPBD alone group. The patients in EPBD alone group were assigned to dilation time ≥5 minutes group (n=35) and time <5 minutes group (n=49). Further, we preliminarily discussed the influence of balloon dilation time on the procedure-related complications.ResultsCompared with EST plus EPBD, the patients in EPBD alone group were younger [56.6 (range: 18 to 95) vs. 65.1 (24 to 92) y; P=0.006], had smaller diameter of the largest stone [10.4 (range: 3 to 20) vs. 12.3 (5 to 30) mm; P<0.001] and were lesser frequently performed with jaundice [22 (26.2%) vs. 189 (45.8%); P=0.001]. The mean duration of postoperative hospital stay in EPBD alone group was significantly shorter than EST plus EPBD group [6.3 (range: 1 to 18) vs. 9.2 (1 to 44) d; P<0.001]. The patients in EPBD alone group had higher risk of post endoscopic retrograde cholangiopancreatography pancreatitis than EST plus EPBD group [11 (13.1%) vs. 22 (5.3%); P=0.009]. Patients in the dilation time <5 minutes group had higher risk to suffer from postoperative pancreatitis than the EST plus EPBD group [9 (18.4%) vs. 22 (5.3%); P=0.002], while patients in the dilation time ≥5 minutes group had less procedure-related hemorrhage than the EST plus EPBD group [0 vs. 36 (8.7%); P=0.047].ConclusionLong balloon dilation time in EPBD alone is safe and effective in treating CBDSs.

Project description:Background/aimsThis study aimed to investigate the patterns of preferred endoscopic procedure types and techniques for managing difficult common bile duct (CBD) stones in South Korea.MethodsThe Committee of Policy and Quality Management of Korean Pancreatobiliary Association (KPBA) conducted a survey containing 19 questions. Both paper and online surveys were carried out; with the paper survey being conducted during the 2019 Annual Congress of KPBA and the online survey being conducted through Google Forms from April 2020 to February 2021.ResultsThe response rate was approximately 41.3% (86/208). Sixty-two (73.0%) worked at tertiary hospitals or academic medical centers, and 60 (69.7%) had more than 5 years of endoscopic retrograde cholangiopancreatography experience. The preferred size criteria for large CBD stones were 15 mm (40.6%), 20 mm (31.3%), and 30 mm (4.6%). For managing of large CBD stones, endoscopic papillary large balloon dilation after endoscopic sphincterotomy was the most preferred technique (74.4%). When performing procedures in those with bleeding diathesis, 64 (74.4%) respondents favored endoscopic papillary balloon dilation (EPBD) alone or EPBD with small endoscopic sphincterotomy. Fifty-five respondents (63.9%) preferred the doubleguidewire technique when faced with difficult bile duct cannulation in patients with periampullary diverticulum. In surgically altered anatomies, cap-fitted forward viewing endoscopy (76.7%) and percutaneous transhepatic cholangioscopy (48.8%) were the preferred techniques for Billroth-II anastomosis and total gastrectomy with Roux-en-Y anastomosis, respectively.ConclusionsMost respondents showed unifying trends for the management of difficult CBD stones. The current practice patterns could be used as basic data for clinical quality improvements in the management of difficult CBD stones.

Project description:Background and study aimsBile stones represent a highly prevalent condition and abnormalities of the biliary tree predispose to stone recurrence due to development of biliary stasis. In our study, we assessed the importance of an altered bile duct course for stone formation.Patients and methods1,307 patients with choledocholithiasis in the absence of any associated hepatobiliary disease who underwent endoscopic retrograde cholangiopancreatography (ERCP) between 2002 and 2009 were analysed. The angle enclosed between the horizontal portion of the common bile duct (CBD) and the horizontal plane was measured (angle ?). Oblique common bile duct (OCBD) was defined as a CBD with angle ? < 45°.Results103 patients (7.9%) were found to harbour OCBD and these were compared to 104 randomly selected control subjects. Compared to controls, OCBD patients were (i) significantly older (72 ± 13 vs. 67 ± 13, p<0.00001); (ii) more frequently underwent a cholecystectomy (p = 0.02) and biliary surgery (p = 0.003) prior to the diagnosis and (iii) more often developed chronic pancreatitis (p = 0.04) as well as biliary fistulae (p = 0.03). Prior to and after ERCP, OCBD subjects displayed significantly elevated cholestatic parameters and angle ? negatively correlated with common bile duct diameter (r = -0.29, p = 0.003). OCBD subjects more often required multiple back-to-back ERCP sessions to remove bile stones (p = 0.005) as well as more ERCPs later on due to recurrent stone formation (p<0.05).ConclusionOCBD defines a novel variant of the biliary tree, which is associated with chronic cholestasis, hampers an efficient stone removal and predisposes to recurrence of bile duct stones.

Project description:Background/aimsTreatment options for difficult bile duct stones are limited. Direct peroral cholangioscopy (POC)-guided lithotripsy may be an option. A newly developed multibending (MB) ultraslim endoscope has several structural features optimized for direct POC. We evaluated the utility of direct POC using an MB ultraslim endoscope for lithotripsy in patients with difficult bile duct stones.MethodsTwenty patients with difficult bile duct stones, in whom stone removal using conventional endoscopic methods, including mechanical lithotripsy, had failed were enrolled from March 2018 to August 2019. Direct POC-guided lithotripsy was performed by electrohydraulic lithotripsy or laser lithotripsy. The primary outcome was complete ductal clearance, defined as the retrieval of all bile duct stones after lithotripsy confirmed by balloon-occluded cholangiography and/or direct POC.ResultsThe technical success rate of direct POC was 100% (20/20), and the free-hand insertion rate was 95% (19/20). Direct POC-guided lithotripsy, attempted by electrohydraulic lithotripsy in nine patients (45%) and laser lithotripsy in 11 patients (55%), was successful in 95% (19/20) of the patients. Complete ductal clearance after direct POC-guided lithotripsy was achieved in 95% (19/20) of patients. Patients required a median of 2 (range, 1-3) endoscopic retrograde cholangiopancreatography sessions for complete stone removal. Adverse event was observed in one patient (5%) with hemobilia and was treated conservatively.ConclusionsDirect POC using an MB ultraslim endoscope was safe and effective for lithotripsy in patients with difficult bile duct stones.

Project description:Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered gastrointestinal anatomy has been reported to be useful. However, selective biliary cannulation through the papilla is difficult in cases with surgically altered gastrointestinal anatomy. Herein, we report a successful biliary cannulation using a pancreatic duct (PD) stent in patients with Roux-en-Y anatomy. A 70-year-old man who underwent total gastrectomy with Roux-en-Y anatomy was admitted to our hospital with jaundice due to recurrence of gastric cancer. ERCP was performed for biliary drainage. We approached the papilla using a short-type single-balloon enteroscope (SIF-H290; Olympus Medical Systems). Because the papilla was positioned tangentially, it was difficult to adjust the catheter in the direction of the bile duct. As only a PD could be cannulated, we placed a guidewire in the PD. Although we attempted the double-guidewire technique using a guidewire placed in PD, selective biliary cannulation was difficult. Therefore, we placed a PD stent 5Fr-5cm (Geenen, Pancreatic Stent Sets, Cook Medical, Bloomington, IN, USA) to assist biliary cannulation. We inserted a catheter crossing the PD stent. With this, selective biliary cannulation was successful. We successfully performed selective biliary cannulation using the PD stent as we were able to fix the papilla, straighten the common channel and the axis of the bile duct, and not restrict scope movement by not using the PD guidewire placement method. This novel technique using a PD stent appears to be useful in patients with surgically altered gastrointestinal anatomy.

Project description:Background and study aims The optimal technique for removal of large common bile duct (CBD) stones (≥ 10 mm) during endoscopic retrograde cholangiopancreatography (ERCP) remains unclear. We aimed to perform a comparative analysis between different endoscopic techniques. Methods Adhering to PRISMA guidelines, a stringent search of the following databases through January 12, 2021, were undertaken: PubMed/Medline, Embase, Web of Science, and Cochrane. Randomized controlled trials comparing the following endoscopic techniques were included: (1) Endoscopic sphincterotomy (EST); (2) Endoscopic papillary large balloon dilation (EPLBD); and (3) EST plus large balloon dilation (ESLBD). Stone clearance rate (SCR) on index ERCP was the primary outcome/endpoint. Need for mechanical lithotripsy (ML) and adverse events were also evaluated as secondary endpoint. Random effects model and frequentist approach were used for statistical analysis. Results A total of 16 studies with 2545 patients (1009 in EST group, 588 in EPLBD group, and 948 patients in ESLBD group) were included. The SCR was significantly higher in ESLBD compared to EST risk ratio [RR]: 1.11, [confidence interval] CI: 1.00-1.24). Lower need for ML was noted for ESLBD (RR: 0.48, CI: 0.31-0.74) and EPLBD (RR: 0.58, CI: 0.34-0.98) compared to EST. All other outcomes including bleeding, perforation, post-ERCP pancreatitis, stone recurrence, cholecystitis, cholangitis, and mortality did not show significant difference between the three groups. Based on network ranking, ESLBD was superior in terms of SCR as well as lower need for ML and adverse events (AEs). Conclusions Based on network meta-analysis, ESLBD seems to be superior with higher SCR and lower need for ML and AEs for large CBD stones.
