Endoscopic sphincteroplasty (ESPT) using a large CRETM Wireguided balloon dilatation is an alternative technique in removing a difficult common bile duct (CBD) stone. However the outcome and complications of endoscopic difficult CBD stone removal using ESPT have not been well demonstrated. The present study revealed the outcome of the technique which done by a single endoscopist. Between January 2003 and December 2009, the retrospective study of ninety-three patients with CBD stones that underwent endoscopic retrograde cholangiopancreaticography (ERCP) for stone removal and had difficulty were enrolled. ESPT using a large CRE Wireguided balloon dilatation was performed in 62 patients. The success rate of complete stone clearance and post ERCP complications were analyzed In the aspect of complete stone removal, the success rate was 88.7%. Seven patients (11.3%) required adjunctive mechanical lithotripsy (ML) for complete stone clearance. This technique was associated with low complic...

Background & Aims: The long-term outcomes of endoscopic papillary balloon dilation (EPBD) for bile duct stone removal are not well known. Methods: A total of 1000 patients with bile duct stones were treated with EPBD. After assessing immediate outcomes, patients were followed up for late biliary complications. Results: Complete bile duct clearance was achieved with EPBD alone in 963 patients (96.3%) in a mean of 1.5 endoscopic sessions. Post-EPBD pancreatitis developed in 48 patients (4.8%), including 1 patient graded as severe. The long-term outcome was evaluated in 837 patients with a mean follow-up period of 4.4 years. Biliary complications were seen in 104 patients (12.4%), and they were less frequent in the cholecystectomy (CCx) after EPBD group than in the gallbladder (GB) left in situ with stones, GB left in situ without stones, and CCx before EPBD groups (2.8% vs 22.6%, 9.2%, and 13.5%, respectively). Stone recurrence was seen in 74 patients (8.8%)-2.4%, 15.6%, 5.9%, and 10.8% in the CCx after EPBD, GB left in situ with stones, GB left in situ without stones, and CCx before EPBD groups, respectively. Lithotripsy and gallbladder status were identified as risk factors for stone recurrence. Cholecystitis occurred in 13 patients (4.5%) in the GB left in situ with stones group. Conclusions: EPBD was effective in treating bile duct stones that were not accompanied by an unacceptably high risk of pancreatitis. Patients with calculous gallbladder had the highest risk for late complications, and cholecystectomy is recommended after removal of their bile duct stones. Methods Patients Between May 1994 and November 2004 a total of 1000 patients with common bile duct stones underwent EPBD as initial treatment in 6 endoscopic units in Tokyo, Japan, and

Background and Aim: Endoscopic papillary balloon dilation (EPBD) has been advocated as an alternative therapy to endoscopic sphincterotomy for bile duct stones. However, studies have shown that EPBD may increase the risk for pancreatitis. Pancreatitis after EPBD is believed to be related to papillary damage after balloon dilation. We changed the dilation method to a theoretically less hazardous one. This modified dilation method was compared with the initial method. Methods: A total of 324 patients with bile duct stones underwent EPBD by the modified method between June 1999 and June 2003. Three hundred and twenty-four patients undergoing EPBD by the initial method served as a historical control group. The success rate of stone removal and the incidence of procedure-related pancreatitis were compared between the two groups. In the modified method, the balloon was inflated until disappearance of the balloon waist, and the pressure was then maintained for 15 s. In the initial method, the balloon was inflated at 8 atmospheres for 2 min. Results: Bile duct stones were successfully removed in 313 of 324 patients (96.6%) in the modified group and in 314 of 324 patients (96.9%) in the initial group (not significant). The incidence of postprocedure pancreatitis showed a lower tendency in the modified group (4.0%, 13/324) than in the initial group (7.4%, 24/324) (P-value = 0.0626). The severity of pancreatitis was significantly reduced in the modified group. Conclusion: The modified method of EPBD is feasible for extraction of bile duct stones, and may potentially decrease the incidence of severe post-EPBD pancreatitis.

Background. Prior Billroth II gastrectomy is an important factor presenting diffi culties in endoscopic retrograde cholangiopancreatography (ERCP) administration. We retrospectively evaluated the usefulness and safety of therapeutic ERCP using an anterior oblique-viewing endoscope for bile duct stones in patients with prior Billroth II gastrectomy. Methods. Forty-three patients with bile duct stones after Billroth II gastrectomy who underwent ERCP from January 1998 to February 2008 were enrolled in this study. We used anterior oblique-viewing endoscopes for all procedures. Endoscopic sphincterotomy was performed using a needle knife guided by a biliary stent. A total of 808 patients without gastrectomy who had undergone ERCP for bile duct stones in the same period were reviewed as controls. Results. The success rate of access to the papilla of Vater was 88.4%, and the average time required for such access was 13 min. In cases of successful access, selective cannulation of the bile duct and complete stone removal were achieved in 94.7% and 94.6% of patients, respectively. The incidence of complications was 4.7%. As for the success rate of selective cannulation, complete stone removal ratio, and the incidence of complications, there were no signifi cant differences compared with the control group. Conclusions. Use of an anterior oblique-viewing endoscope enables good success rates in selective cannulation and complete stone removal to be achieved in patients with prior Billroth II gastrectomy. The safety of therapeutic ERCP for removal of bile duct stones in those patients is comparable to that in patients with normal anatomy.
Early Complications of Endoscopic Sphincterotomy for Common Bile Duct Stones
Digestive Endoscopy, 2007
Endoscopic sphincterotomy (EST) is the technique most commonly used to perform therapeutic endoscopic retrograde cholangiopancreatography (ERCP). Recently, endoscopic papillary balloon dilatation (EPBD) has been frequently used at many hospitals instead of EST to perform procedures on the papilla. A key factor in the safe, successful outcome of therapeutic ERCP in patients with common bile duct (CBD) stones is the selection of the best-suited procedure based on a thorough understanding of the characteristics of EST and EPBD. The most common early complications of EST are acute pancreatitis and papillary bleeding. Other complications include gastrointestinal perforation and biliary infections. However, whether EST increases the risk of acute pancreatitis remains controversial. The risk of bleeding can be decreased to some degree by the proper selection of patients, improved skills of operators, and the optimal use of peripheral devices. EST performed according to the recently developed endocut method can reduce the risk of bleeding.

The removal of large bile duct stones (>12 mm) after endoscopic sphincterotomy (EST) remains a challenging issue in therapeutic endoscopy. The aim of this prospective, randomized, controlled trial was to compare the effectiveness and complications of EST followed by large balloon dilation (LBD) with that of EST followed by mechanical lithotripsy (ML) for the management of large bile duct stones. A total of 90 patients with large bile duct stones (12-20 mm) were randomized to EST followed by LBD (n=45) or EST followed by ML (n=45). Success rate was determined with a final cholangiogram, whereas type and rate of post-procedure complications were assessed prospectively. Complete bile duct stone removal was accomplished in 97.7% of patients subjected to EST-LBD as compared with 91.1% of those subjected to EST-ML (P=0.36). Post-procedure complications were observed in two (4.4%) patients subjected to EST-LBD and in nine (20%) patients subjected to EST-ML (P=0.049). Rates of pancreatit...

To evaluate the effectiveness of endoscopic balloon sphincteroplasty as an adjunct to endoscopic sphincterotomy in removing large and difficult bile duct stones. A prospective non-randomized descriptive study was conducted at the Endoscopic Service of Surgical Unit 4, Civil Hospital Karachi over a period of 2 years from February 2007 to January 2009. A total of 84 patients where the biliary calculus was either greater than 15 mm or difficult to remove with standard techniques underwent ERCP with endoscopic sphincterotomy and balloon sphincteroplasty. Patients with diagnosis of cholangitis or pancreatitis were excluded from the study. Endoscopic balloon dilatation was performed after standard sphincterotomy by using standard 15-18 mm Controlled Radial Expansion (CRE) balloons. All procedures were done as day case under conscious sedation. There were 18 (21.4%) male and 66 (78.6%) females. Age of the study population ranged from 16-85 years with a mean of 48.38 +/- 17.07 years. The si...
