Is endoscopic papillary large balloon dilatation without endoscopic sphincterotomy effective? World J Gastroenterol 2015; 21:7289-7296. [PMID: 26109817 PMCID: PMC4476892 DOI: 10.3748/wjg.v21.i23.7289] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2014] [Revised: 11/19/2014] [Accepted: 02/05/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the safety and efficacy of endoscopic papillary large balloon dilatation (EPLBD) without endoscopic sphincterotomy in a prospective study.
METHODS: From July 2011 to August 2013, we performed EPLBD on 41 patients with naïve papillae prospectively. For sphincteroplasty of EPLBD, endoscopic sphincterotomy (EST) was not performed, and balloon diameter selection was based on the distal common bile duct diameter. The balloon was inflated to the desired pressure. If the balloon waist did not disappear, and the desired pressure was satisfied, we judged the dilatation as complete. We used a retrieval balloon catheter or mechanical lithotripter (ML) to remove stones and assessed the rates of complete stone removal, number of sessions, use of ML and adverse events. Furthermore, we compared the presence or absence of balloon waist disappearance with clinical characteristics and endoscopic outcome.
RESULTS: The mean diameters of the distal and maximum common bile duct were 13.5 ± 2.4 mm and 16.4 ± 3.1 mm, respectively. The mean maximum transverse-diameter of the stones was 13.4 ± 3.4 mm, and the mean number of stones was 3.0 ± 2.4. Complete stone removal was achieved in 97.5% (40/41) of cases, and ML was used in 12.2% (5/41) of cases. The mean number of sessions required was 1.2 ± 0.62. Pancreatitis developed in two patients and perforation in one. The rate of balloon waist disappearance was 73.1% (30/41). No significant differences were noted in procedure time, rate of complete stone removal (100% vs 100%), number of sessions (1.1 vs 1.3, P = 0.22), application of ML (13% vs 9%, P = 0.71), or occurrence of pancreatitis (3.3% vs 9.1%, P = 0.45) between cases with and without balloon waist disappearance.
CONCLUSION: EST before sphincteroplasty may be unnecessary in EPLBD. Further investigations are needed to verify the relationship between the presence or absence of balloon waist disappearance.

Safety and efficacy of endoscopic retrograde cholangiopancreatography for common bile duct stones in liver cirrhotic patients. ACTA ACUST UNITED AC 2014; 34:612-615. [PMID: 25135737 DOI: 10.1007/s11596-014-1325-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2014] [Revised: 06/08/2014] [Indexed: 12/15/2022]
Abstract
In order to investigate the safety and efficacy of endoscopic retrograde cholangiopancreatograpy (ERCP) in liver cirrhosis patients with common bile duct stones, we retrospectively analyzed data of 46 common bile duct stones patients with liver cirrhosis who underwent ERCP between 2000 and 2008. There were 12 cases of Child-Pugh A, 26 cases of Child-Pugh B, and 8 cases of Child-Pugh C. 100 common bile duct stones patients without liver cirrhosis were randomly selected. All the patients were subjected to ERCP for biliary stones extraction. The rates of bile duct clearance and complications were compared between cirrhotic and non-cirrhotic patients. The success rate of selective biliary cannulation was 95.6% in liver cirrhotic patients versus 97% in non-cirrhotic patients (P>0.05). The bile duct clearance rate was 87% in cirrhotic patients versus 96% in non-cirrhotic patients, but the difference was not statistically significant. Two liver cirrhotic patients (4.35%, 2/46) who were scored Child-Pugh C had hematemesis and melena 24 h after ERCP. The hemorrhage rate after ERCP in non-cirrhotic patients was 3%. The hemorrhage rate associated with ERCP in Child-Pugh C patients was significantly higher (25%, 2/8) than that (3%, 3/100) in non-cirrhotic patients (P<0.01%). There was no significant difference between these two groups in the rate of post-ERCP pancreatitis (PEP) and cholangitis. ERCP is safe and effective for Child-Pugh A and B cirrhotic patients with common bile duct stones. Hemorrhage risk in ERCP is higher in Child-Pugh C patients.

Abstract
BACKGROUND AND STUDY AIMS Biliary and pancreatic diseases are common in the elderly; however, few studies have addressed the occurrence of adverse events in elderly patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Our objective was to determine the incidence rates of specific adverse events in this group and calculate incidence rate ratios (IRRs) for selected comparison groups. PATIENTS AND METHODS Bibliographical searches were conducted in Medline, EMBASE, and Cochrane library databases. The studies included documented the incidence of adverse events (perforation, pancreatitis, bleeding, cholangitis, cardiopulmonary adverse events, mortality) in patients aged ≥ 65 who underwent ERCP. Pooled incidence rates were calculated for each reported adverse event and IRRs were determined for available comparison groups. A parallel analysis was performed in patients aged ≥ 80 and ≥ 90. RESULTS Our literature search yielded 7429 articles, of which 69 studies met our inclusion criteria. Pooled incidence rates for adverse events (per 1000 ERCPs) in patients aged ≥ 65 were as follows: perforation 3.8 (95 %CI 1.8 - 7.0), pancreatitis 13.1 (95 %CI 11.0 - 15.5), bleeding 7.7 (95 %CI 5.7 - 10.1), cholangitis 16.1 (95 %CI 11.7 - 21.7), cardiopulmonary events 3.7 (95 %CI 1.5 - 7.6), and death 7.1 (95 %CI 5.2 - 9.4). Patients ≥ 65 had lower rates of pancreatitis (IRR 0.3, 95 %CI 0.3 - 0.4) compared with younger patients. Octogenarians had higher rates of death (IRR 2.4, 95 %CI 1.3 - 4.5) compared with younger patients, whereas nonagenarians had increased rates of bleeding (IRR 2.4, 95 %CI 1.1 - 5.2), cardiopulmonary events (IRR 3.7, 95 %CI 1.0 - 13.9), and death (IRR 3.8, 95 %CI 1.0 - 14.4). Conclusions ERCP appears to be safe in elderly patients, except in the very elderly who are at higher risk of some adverse events. These data on adverse event rates can help to inform clinical decision-making, the consent process, and comparative effectiveness analyses.

Endoscopic papillary balloon dilation for difficult common bile duct stones: Our experience. World J Clin Cases 2013; 1:19-24. [PMID: 24303455 PMCID: PMC3845931 DOI: 10.12998/wjcc.v1.i1.19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2012] [Revised: 02/12/2013] [Accepted: 03/23/2013] [Indexed: 02/05/2023] Open
Abstract
AIM: To evaluate the efficacy and safety of endoscopic balloon dilation (EBD) performed for common bile duct (CBD) stones.
METHODS: From a computer database, we retrospectively analyzed the data relating to EBD performed in patients at the gastrointestinal unit of the Sandro Pertini Hospital of Rome (small center with low case volume) who underwent endoscopic retrograde cholangiopancreatography (ERCP) for CBD from January 1, 2010 to February 29, 2012. All patients had a proven diagnosis of CBD stones studied with echography, RMN-cholangiography and, when necessary, with computed tomography of the abdomen (for example, in cases with pace-makers). Prophylactic therapies, with gabexate mesilate 24 h before the procedure and with an antibiotic (ceftriaxone 2 g) 1 h before, were administered in all patients. The duodenum was intubated with a side-viewing endoscope under deep sedation with intravenous midazolam and propofol. The patients were placed in the supine position in almost all cases. EBD of the ampulla was performed under endoscopic and fluoroscopic guidance with a balloon through the scope (Hercules, wireguided balloon®, Cook Ireland Ltd. and CRE®, Microvasive, Boston Scientific Co., Natick, MA, United States).
RESULTS: A total of 14 patients (9 female, 5 male; mean age of 73 years; range 57-82 years) were enrolled in the study, in whom a total of 15 EBDs were performed. All patients underwent minor endoscopic sphincterotomy (ES) prior to the EBD. The size of balloon insufflation depended on stone size and CBD dilation and this was performed until it reached 16 mm in diameter. EBD was performed under endoscopic and fluoroscopic guidance. The balloon was gradually filled with diluted contrast agent and was maintained inflated in position for 45 to 60 s before deflation and removal. The need for precutting the major papilla was 21.4%. In one patient (an 81-year-old), EBD was performed in a Billroth II. Periampullary diverticula were found only in a 74-year-old female. The adverse event related to the procedures (ERCP + ES) was only an intra procedural bleeding (6.6%) that occurred after ES and was treated immediately with adrenaline sclerotherapy. No postoperative complications were reported.
CONCLUSION: With the current endoscopic techniques, very few patients with choledocholithiasis require surgery. EBD is an efficacious and safe procedure.

Abstract
Endoscopy is widely accepted as the first treatment option in the management of bile duct stones. In this review we focus on the alternative endoscopic modalities for the management of difficult common bile duct stones. Most biliary stones can be removed with an extraction balloon, extraction basket or mechanical lithotripsy after endoscopic sphincterotomy. Endoscopic papillary balloon dilation with or without endoscopic sphincterotomy or mechanical lithotripsy has been shown to be effective for management of difficult to remove bile duct stones in selected patients. Ductal clearance can be safely achieved with peroral cholangioscopy guided laser or electrohydraulic lithotripsy in most cases where other endoscopic treatment modalities have failed. Biliary stenting may be an alternative treatment option for frail and elderly patients or those with serious co morbidities.

Abstract
Endoscopic sphincterotomy (EST) is considered as a possible etiological factor for severe cholangitis. We herein report a case of severe cholangitis after endoscopic sphincterotomy induced by barium examination. An adult male patient presented with epigastric pain was diagnosed as having choledocholithiasis by ultrasonography. EST was performed and the stone was completely cleaned. Barium examination was done 3 d after EST and severe cholangitis appeared 4 h later. The patient was recovered after treated with tienam for 4 d. Barium examination may induce severe cholangitis in patients after EST, although rare, barium examination should be chosen cautiously. Cautions should be also used when EST is performed in patients younger than 50 years to avoid the damage to the sphincter of Oddi.

Abstract
AIM: To assess the efficacy and safety of endoscopic papillary large balloon dilation after biliary sphincterotomy for difficult bile duct stones retrieval.
METHODS: Retrospective review of consecutive patients submitted to the technique during 18 mo. The main outcomes considered were: efficacy of the procedure (complete stone clearance; number of sessions; need of lithotripsy) and complications.
RESULTS: A total of 30 patients with a mean age of 68 ± 10 years, 23 female (77%) and 7 male (23%) were enrolled. In 10 patients, a single stone was found in the common bile duct (33%) and in 20 patients multiple stones (67%) were found. The median diameter of the stones was 17 mm (12-30 mm). Dilations were performed with progressive diameter Through-The-Scope balloons (up to 12, 15) or 18 mm. Complete retrieval of stones was achieved in a single session in 25 patients (84%) and in two sessions in 4 patients (13%). Failure occurred in 1 case (6%). Mechanical lithotripsy was performed in 6 cases (20%). No severe complications occurred. One patient (3%) had mild-grade post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis.
CONCLUSION: Endoscopic balloon dilatation with a large balloon after endoscopic sphincterotomy is a safe and effective technique that could be considered an alternative choice in therapeutic ERCP.

Abstract
BACKGROUND AND AIM Endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincterotomy (EST) are two common nonsurgical treatments endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. The aim of this study was to compare the efficacy and safety of EPBD and EST in the treatment for choledocholithiasis, confining the analysis to work reported in the last decade. METHODS The rate of overall postoperative complications was chosen as the primary outcome, and 10 other outcomes were secondary outcomes. Relative risk (RR) or Peto odds ratio (OR) were computed as the measures of pooled effects. We planned sensitivity analyses a priori for examining the change in robustness of the sensitivity to excluding studies with some inappropriate objects, technique defects or without full-text acquisition. RESULTS For complete stone removal, EPBD was similar to EST (95% vs. 96%, P = 0.36) and overall postoperative complications (14.0% vs. 11.7%, P = 0.53). The incidence of post-ERCP cholangitis (2.5% vs. 1.8%, P = 0.40), basket impaction (0.9% vs. 0%, P = 0.16) and perforation (0.0% vs. 0.4%, P = 0.17) were equivalent between EPBD and EST. On the other hand, EPBD caused more post-ERCP pancreatitis (PEP) (9.4% vs. 3.3%, P < 0.00001), but less hemorrhage (0.1% vs. 4.2%, P < 0.00001). People undergoing EPBD required more use of endoscopic mechanical lithotripsy (35.0% vs. 26.2%, P = 0.0004). The results of sensitivity analyses showed no substantial change. CONCLUSION EPBD is comparable to EST for stone extraction, though it requires more endoscopic mechanical lithotripsy (EML). EPBD may outweigh EST for patients with coagulopathy; however, it may cause more PEP.

Abstract
Background/purpose While endoscopic sphincterotomy (EST) is performed worldwide for the removal of common bile duct stones, many biliary endoscopists hesitate to regard endoscopic papillary balloon dilation (EPBD) as a standard procedure for treatment. Therefore, the aim of this review is to re-evaluate the status of EPBD for the treatment of common bile duct stones. Results A major benefit of EPBD is preservation of papillary function, which is not complete but may be greater than that after EST. The disadvantages of EPBD compared with EST are that EPBD is difficult to use for the removal of larger stones because of the smaller biliary opening, it requires more frequent use of mechanical lithotripsy, and it is associated with a higher incidence of pancreatitis, although the risks of bleeding and perforation are low. Since the biliary sphincter is easily dilated with a balloon catheter, EPBD may be effective for patients with anatomic anomalies, such as after gastric bypass surgery or in the presence of a periampullary diverticulum. No standard procedure exists to reduce the risk of acute pancreatitis with EPBD. Conclusion EPBD is feasible, however, we must pursue less hazardous techniques of papillary balloon dilation. Furthermore, we must understand the benefits and limitations of EPBD and determine whether it could provide clinical benefits for long-term complications.

Abstract
BACKGROUND The aim of this study was to evaluate short- and long-term outcomes in relatively young patients (≤ 60 years old) who underwent endoscopic papillary balloon dilation (EPBD) for bile duct stone removal. METHODS Immediate and long-term outcomes were evaluated in 311 patients who were 60 years old or younger at the time of EPBD. The stone recurrence rate was compared among four groups stratified according to gallbladder (GB) status before and after EPBD (cholecystectomy after EPBD, GB left in situ with stones, GB left in situ without stones, and cholecystectomy before EPBD). RESULTS Bile duct stones were completely removed via EPBD alone in 304 patients (97.7%). Post-EPBD pancreatitis occurred in 24 patients (7.7%), and was mild in 18 patients, moderate in 5 patients, and severe in 1 patient. The rate of pancreatitis was significantly higher in these patients than in patients aged more than 60 years who underwent EPBD during the same study period (4.7%). Long-term outcomes were evaluated in 217 patients who were followed for at least 1 year after complete stone removal via EPBD. During a mean follow-up period of 5.6 years (range, 1.0-13.4 years), stone recurrence was observed in 13 patients (6.0%). The cumulative stone recurrence rates at 5 and 10 years after EPBD were 5.9 and 7.1%, respectively. Patients in the cholecystectomy after EPBD group had the lowest risk of stone recurrence among the four groups (2.0%). CONCLUSION EPBD removes bile duct stones in the majority of younger patients without increasing the risk of severe pancreatitis. Post-EPBD pancreatitis is more likely to occur in younger patients as compared to older patients. The long-term outcomes of EPBD appear favorable, especially in patients who have undergone cholecystectomy after EPBD.

Abstract
The endoscopic method is accepted as a first treatment modality in the management of extrahepatic bile duct. Most large stones can be removed with basket and mechanical lithotripsy after endoscopic sphincterotomy. Currently, in treating large extrahepatic bile duct stones, endoscopic papillary large balloon dilation with mid-incision endoscopic sphincterotomy is actively performed instead of applying mechanical lithotripsy after full endoscopic sphincterotomy. Herein, we describe the conceptions, proper indications, methods and complications of endoscopic papillary large balloon dilation with regards to currently published reports. In addition, intracorporeal lithotripsy by peroral cholangioscopy with an ultra-slim upper endoscope is introduced, which is more convenient than previous conventional intracorporeal lithotripsy methods using mother-baby endoscopy or percutaneous transhepatic cholangioscopy. Lastly, biliary stenting with the choleretic agent administration method is briefly reviewed as an alternative treatment option for frail and elderly patients with large impacted common bile duct stones.

Abstract
AIM: To compare small sphincterotomy combined with endoscopic papillary large balloon dilation (SES + ELBD) and endoscopic sphincterotomy (EST) for large bile duct stones.
METHODS: We compared prospectively SES + ELBD (group A, n = 27) with conventional EST (group B, n = 28) for the treatment of large bile duct stones (≥ 15 mm). When the stone could not be removed with a normal basket, mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy.
RESULTS: No significant differences were observed in the mean largest stone size (A: 20.8 mm, B: 21.3 mm), bile duct diameter (A: 21.4 mm, B: 20.5 mm), number of stones (A: 2.2, B: 2.3), or procedure time (A: 18 min, B: 19 min) between the two groups. The rates of complete stone removal with one session was 85% in group A and 86% in group B (P = 0.473). Mechanical lithotripsy was required for stone removal in nine of 27 patients (33%) in group A and nine of 28 patients (32%, P = 0.527) in group B.
CONCLUSION: SES + ELBD did not show significant benefits compared to conventional EST, especially for the removal of large (≥ 15 mm) bile duct stones.

Abstract
BACKGROUND Little is known about the long-term results of endoscopic papillary balloon dilation (EPBD) for bile duct stones. METHODS Between 1995 and 2000, 204 patients with bile duct stones successfully underwent EPBD and stone removal. Complete stone clearance was confirmed using balloon cholangiography and intraductal ultrasonography (IDUS). Long-term outcomes of EPBD were investigated retrospectively in the year 2007, and risk factors for stone recurrence were multivariately analyzed. RESULTS Long-term information was available in 182 cases (89.2%), with a mean overall follow-up duration of 9.3 years. Late biliary complications occurred in 22 patients (12.1%), stone recurrence in 13 (7.1%), cholangitis in 10 (5.5%), cholecystitis in four, and gallstone pancreatitis in one. In 11 of 13 patients (84.6%), stone recurrence developed within 3 years after EPBD. All recurrent stones were bilirubinate. Multivariate analysis identified three risk factors for stone recurrence: dilated bile duct (>15 mm), previous cholecystectomy, and no confirmation of clean duct using IDUS. CONCLUSION Approximately 7% of patients develop stone recurrence after EPBD; however, retreatment with endoscopic retrograde cholangiopancreatography is effective. Careful follow up is necessary in patients with dilated bile duct or previous cholecystectomy. IDUS is useful for reducing stone recurrence after EPBD.

Abstract
BACKGROUND AND AIM The aim of the present study was to determine whether additional intraductal ultrasound (IDUS) to confirm complete stone clearance decreases the recurrence rate of common bile duct stones for a 3-year period after endoscopic papillotomy (EPT). METHODS IDUS was carried out with a thin-caliber ultrasonic probe (diameter 2.0 mm, frequency 20 MHz) via transpapillary route after stone extraction. If IDUS showed evidence of residual stones and/or sludge, endoscopic management was performed until IDUS examination was negative. A prospective study was conducted on 59 consecutive patients undergoing additional IDUS after stone extraction between January 1996 and May 2003 (IDUS group). The recurrence rate of common bile duct stones was compared with a historical control group (August 1988 to December 1995) consisting of cases that did not undergo IDUS (non-IDUS group). Potential risk factors for recurrence of common bile duct stones were assessed by univariate and multivariate analysis on logistic regression. RESULTS In 14 of 59 patients (23.7%), IDUS detected small residual stones not seen on cholangiography. The recurrence rate was 13.2% (17 of 129 patients) in the non-IDUS group and 3.4% (two of 59 patients) in the IDUS group (P < 0.05). Multivariate analysis subsequently identified non-IDUS status as an independent risk factor for recurrence (odds ratio 5.12, 95% CI 1.11-23.52, P = 0.036). CONCLUSIONS Additional IDUS to confirm complete stone clearance after EPT decreases the early recurrence rate of common bile duct stones.

Abstract
The definition of large stones is not clear ranging from 10 mm to 15 mm and does not include the lower common bile duct (CBD) diameter. Three hundred and four patients who underwent endoscopic retrograde cholangiopancreatography and stone extraction were retrospectively analyzed over a 1-year period. Sixteen patients were different from others in that 10 patients with large stones had stone extraction with a wire basket or a balloon catheter and 6 patients with small stones had stone extraction with mechanical lithotripsy. The definition of large stones should include diameter of the lower CBD and any stone exceeding 2 mm than the lower CBD diameter should be called large stone irrespective of the size of the stone.

Abstract
BACKGROUND Endoscopic balloon dilation was introduced as an alternative to endoscopic sphincterotomy to preserve the sphincter of Oddi and avoid undesirable effects due to an incompetent sphincter. Endoscopic balloon dilation has been largely abandoned by USA endoscopists due to increased risks of pancreatitis noted in one multicentre trial, but is still practiced in parts of Asia and Europe. OBJECTIVES To assess the beneficial and harmful effects of endoscopic balloon dilation versus endoscopic sphincterotomy in the management of common bile duct stones. SEARCH STRATEGY We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, and EMBASE until January 2004. We hand searched Gastrointestinal Endoscopy (1983-2002), read through bibliographies of all included randomised clinical trials, and contacted all primary authors regarding missed randomised trials. SELECTION CRITERIA Randomised clinical trials comparing endoscopic balloon dilation versus endoscopic sphincterotomy in removal of common bile duct stones irrespective of publication status, language, or blinding. DATA COLLECTION AND ANALYSIS Data collection was done by two independent authors for decisions on study inclusion, data abstraction, and quality assessment. When there was a non-resolvable discrepancy, the third author made the final decision. Analysis was run with RevMan Analysis. MAIN RESULTS Fifteen randomised trials met our inclusion criteria (1768 participants). Less than half of the trials reported adequate methods of randomisation and only two trials used blinded outcome assessment. Endoscopic balloon dilation is statistically less successful for stone removal (relative risk (RR) 0.90, 95% confidence interval (CI) 0.84 to 0.97), requires higher rates of mechanical lithotripsy (RR 1.34, 95% CI 1.08 to 1.66), and carries a higher risk of pancreatitis (RR 1.96, 95% CI 1.34 to 2.89). Conversely, endoscopic balloon dilation has statistically significant lower rates of bleeding. When a fixed-effect model is applied endoscopic balloon dilation leads to significantly less short-term infection and long-term infection. There was no statistically significant difference with regards to mortality, perforation, or total short-term complications. AUTHORS' CONCLUSIONS Endoscopic balloon dilation is slightly less successful than endoscopic sphincterotomy in stone extraction and more risky regarding pancreatitis. However, endoscopic balloon dilation seems to have a clinical role in patients who have coagulopathy, who are at risk for infection, and possibly in those who are older.

Abstract
BACKGROUND/PURPOSE Endoscopic papillary balloon dilatation (EPBD) is one of the methods used to remove bile duct stones. EPBD may preserve the function of the sphincter of Oddi in spite of the potential risk of acute pancreatitis caused by the procedure. There are only few reports of attempts to reduce the risk of acute pancreatitis in EPBD. METHODS We performed EPBD for bile duct stone removal in 201 patients. We used an 8-mm balloon followed by drip infusion of isosorbide dinitrate (ISDN) at a rate of 5 mg/h for low-pressure EPBD. The function of the minor duodenal papilla, the inflation pressure required for the disappearance of the notch sign in the bile duct, and the serum amylase level after EPBD were observed. RESULTS The median serum amylase level after the procedure was 367 IU/l. Acute pancreatitis occurred in two patients (1.0%). The two patients with acute pancreatitis had poor function of the minor duodenal papilla, a high inflation pressure (over 5 atm) required for disappearance of the notch, sign, and severe abdominal pain during balloon inflation; as well, the procedure took a long time. The rate of duct clearance was 99.5%. CONCLUSIONS EPBD with gradual inflation of the balloon at a low pressure, followed by ISDN drip infusion, could decrease the risk of acute pancreatitis associated with the procedure. Poor function of the minor duodenal papilla, high inflation pressure required for disappearance of the notch, sign, severe abdominal pain, and a lengthy procedure increase the risk of acute pancreatitis after EPBD.

Abstract
Endoscopic therapy for biliary tract disease in patients with end-stage liver disease (ESLD) before liver transplantation is safe and effective. Reported results in patients with choledocholithiasis, primary sclerosing cholangitis (PSC), and symptomatic gallbladder diseases are encouraging. Prompt recognition and appropriate treatment of symptomatic gallbladder and bile duct disease are important in reducing morbidity and mortality in these high-risk patients while they await liver transplantation. Confirmation of tissue diagnosis of cholangiocarcinoma in patients with sclerosing cholangitis is still difficult. Better screening tools and diagnostic methods are necessary for early detection. Because liver transplantation is the only definitive therapy for patients with advanced cirrhosis, maintenance of their candidacy with either endoscopic or radiologic therapeutic interventions is warranted until transplantation. Endoscopic therapy is the preferred method when feasible. If necessary, percutaneous transhepatic biliary drainage (PTBD) is a viable alternative because both avoid the attendant risks of surgery in a high-risk population with advanced liver disease.

Abstract
OBJECTIVE Endoscopic papillary balloon dilatation (EPBD) has been reported to increase the risk of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (4%-11%). Based on the hypothesis that performing endoscopic nasobiliary drainage (ENBD) could prevent this complication, we performed EPBD combined with ENBD (EPBD/ENBD) and analyzed the risk of pancreatitis. METHODS Thirty-four patients underwent EPBD followed by ENBD for common bile duct stone(s). Serum amylase levels the following morning and incidence of pancreatitis were compared with those previously reported and with complications of simple diagnostic ERCP performed in our institution. RESULTS After EPBD/ENBD, amylase levels the following morning were 214.5 +/- 152.9 U/L, and no cases developed pancreatitis or hyperamylasemia (>3 times normal). These outcomes were favorable compared with previous EPBD reports. Furthermore, despite the stress of EPBD/ENBD after ERCP, these outcomes were better, even compared with simple ERCP performed at our institution [amylase levels: 318.7 +/- 475.2 U/L; hyperamylasemia: 16.5% (P = 0.006); pancreatitis: 7.1%]. CONCLUSION Although EPBD has been regarded as a risk factor for post-ERCP pancreatitis, our results suggest the possibility that application of ENBD after EPBD decreases the incidence of pancreatitis and should be studied further. We speculate that ENBD itself prevents pancreatic duct obstruction by residual stones or papillary edema.

Abstract
OBJECTIVES Endoscopic papillary balloon dilation has been accepted as a possible alternative to endoscopic sphincterotomy, especially in patients with impaired hemostasis. However, pancreatitis associated with endoscopic papillary balloon dilation has remained a controversial, serious issue. The aim of the study was to investigate the risk factors for postendoscopic papillary balloon dilation pancreatitis in a single-center study. METHODS A total of 304 patients who underwent endoscopic papillary balloon dilation for the management of common bile duct stones were enrolled. The risk of postendoscopic papillary balloon dilation pancreatitis was evaluated and the risk factors were analyzed by univariate and multivariate analysis. Definition and grade of the severity of postendoscopic papillary balloon dilation pancreatitis were based on the 1991 consensus guidelines. RESULTS Common bile duct was cleared in 292 of 304 patients (96%). Procedure-related pancreatitis occurred in 15 patients (5.0%). The grade was mild in 8 and moderate in 7. Two risk factors, stone diameter and contrast medium injection to the pancreas, were identified by univariate analysis. Finally, only the contrast medium injection to the pancreas was statistically significant by multivariate analysis. Prior history of pancreatitis was identified as a risk factor for postendoscopic papillary balloon dilation pancreatitis in previous studies, but this factor was not identified as a risk factor in our series. CONCLUSIONS Although the pathogenesis of pancreatitis after endoscopic papillary balloon dilation remains unresolved, the unnecessary injection of contrast medium to the pancreas can certainly be considered to be associated with the increased risk of pancreatitis.

Abstract
We prospectively studied long-term (5 years) effects of endoscopic papillary balloon dilation (EPBD) on gallbladder motility. Thirteen patients with intact gallbladders (six with and seven without gallbladder stones) who had undergone EPBD for choledocholithiasis were enrolled in this study. Gallbladder volumes, while fasting and after dried egg yolk ingestion, were determined by ultrasonography, before and at 7 days, 1 month, and 1, 2, and 5 years after EPBD. Before EPBD, the gallbladder had a larger fasting volume and lower yolk-stimulated maximum contraction than in normal controls. Seven days after EPBD, fasting volume was decreased and maximum contraction was increased, regardless of whether the patient had gallbladder stones, showing significant differences from the pre-EPBD values. At 1 month to 5 years after EPBD, these changes were far less evident and gallbladder function did not differ significantly from baseline. EPBD does not adversely affect gallbladder motility in the long-term (5 years).

Abstract
OBJECTIVES To compare the effect of endoscopic balloon dilation (EPBD) of the papilla with that of endoscopic biliary sphincterotomy (EST) in the treatment of patients with common bile duct stones. METHODS Searches of computerized bibliographic and scientific citations, and review of citations in relevant primary articles. Eight fully published prospective, randomized trials in English that compared EPBD with EST for the removal of common bile duct stones were subjected to metaanalysis. RESULTS EPBD compared with EST resulted in similar outcomes with regards to overall successful stone removal (94.3% vs 96.5%) and overall complications (10.5% vs 10.3%). Bleeding occurred less frequently with EPBD (0% vs 2.0%, p = 0.001). Post-ERCP pancreatitis occurred more commonly in the EPBD group (7.4% vs 4.3%, p = 0.05). No significant differences were seen in the rates of perforation or infection. Patients undergoing EPBD were more likely to require mechanical lithotripsy for stone extraction (20.9% vs 14.8%, p = 0.014). CONCLUSIONS On the basis of lower rates of bleeding, EPBD should be the preferred strategy over EST for endoscopic removal of common bile duct stones in patients with coagulopathy. Although EPBD is theoretically attractive for use in young patients for biliary sphincter preservation, the rate of pancreatitis is higher with EPBD and cannot be routinely recommended at this time.

Abstract
BACKGROUND Endoscopic papillary balloon dilation reduces sphincter function at least transiently or partially, which may allow pancreatobiliary and duodenobiliary reflux to occur. This study prospectively evaluated pancreatobiliary and duodenobiliary reflux after endoscopic papillary balloon dilation. METHODS In 12 patients with choledocholithiasis, ductal bile was sampled for amylase concentration and bacterial culture during ERCP, before and at 7 days to 5 years after endoscopic papillary balloon dilation. To provide comparative and control data, ductal bile was sampled in 12 patients with gallbladder cholesterol polyps and 6 with anomalous pancreaticobiliary junction who did not undergo endoscopic papillary balloon dilation. RESULTS Amylase concentrations in ductal bile from patients with choledocholithiasis before endoscopic papillary balloon dilation were marginally significantly higher (before Bonferroni correction) compared with concentrations in bile from patients with gallbladder polyps. The concentration of amylase in bile was significantly increased at 7 days after endoscopic papillary balloon dilation compared with that before endoscopic papillary balloon dilation; the level was comparable with that of patients with an anomalous pancreaticobiliary junction. Subsequently, the amylase concentration gradually decreased and was approximately equal to the pre-endoscopic papillary balloon dilation level at 1 year. Bacteriocholia was frequent (67%-92%) for up to 3 months after endoscopic papillary balloon dilation but was rare thereafter. CONCLUSIONS Endoscopic papillary balloon dilation causes transient pancreatobiliary and duodenobiliary reflux. However, reflux is no longer present at 1 year after endoscopic papillary balloon dilation.

Abstract
Endoscopic papillary balloon dilation (EPBD) offers an alternative to endoscopic sphincterotomy (EST), which preserves the barrier function of the biliary sphincter. However, reports of increased complications, especially pancreatitis, have stalled the widespread adoption of this technique. A metaanalysis of randomized trials of EPBD versus EST found similar overall complication rates (10.5% vs 10.3%). However, while postprocedure bleeding was reduced with EPBD compared to EST (0% vs 2.0%), the rate of postprocedure pancreatitis was higher (7.4% vs 4.3%). In addition, 20% of EPBD cases required "rescue" EST. EPBD should probably be reserved for special indications, such as uncorrected or anticipated coagulopathy, and unfavorable endoscopic anatomy for EST.

Abstract
OBJECTIVE To prospectively analyze the results obtained with papillary balloon dilatation (PBD) in the treatment of common bile duct stones in patients at risk of complications if endoscopic sphincterotomy (ES) were performed. PATIENTS AND METHOD Thirty-three patients were included between January 2001 and June 2003 (mean age 76.2 years). The criteria for PBD were: choledocholithiasis < or =10 mm in patients with peripapillary diverticula, hemostatic alterations, Billroth-II, and preservation of Oddi's sphincter. In 79% of the patients sedation was performed by an anesthetist. PBD was performed with a balloon catheter dilator with a diameter of 8 or 10 mm for 2 minutes. The efficacy and duration of the procedure as well as complications at 30 days and patient satisfaction were evaluated. RESULTS Stone extraction was achieved in all patients (100%). The mean duration of the procedure was 26 minutes. Two patients (6%) presented mild pancreatitis. Serum amylase was elevated in 16 patients (48%): > or =3 times (post-PBD hyperamylasemia) in 11 (33%). The procedure caused no discomfort in 25/26 (96%) of the patients sedated by an anesthetist vs 2/5 patients (49%) who underwent endoscopic sedation. CONCLUSIONS PBD is an effective and simple therapeutic option in the treatment of small common bile duct stones (< or =10 mm) and in patients at high risk. The duration of endoscopic retrograde cholangiopancreatography is not prolonged. Complications are infrequent (6%) and mild. Post-PBD hyperamylasemia is frequent and generally without clinical importance. Sedation by an anesthetist improves patient satisfaction.

Abstract
BACKGROUND Little is known about the long-term outcome of endoscopic papillary balloon dilation for removal of bile duct stones. A randomized trial that compared long-term outcomes after endoscopic papillary balloon dilation and endoscopic sphincterotomy was conducted. METHODS Thirty-two patients with bile duct stones were randomized to endoscopic papillary balloon dilation or endoscopic sphincterotomy, with 16 patients in each group. Endoscopic papillary balloon dilation was performed by using an 8-mm-diameter balloon; endoscopic sphincterotomy was performed in the standard manner. The success rates for stone removal, as well as the frequency and types of early (<15 days), mid-term (<1 year), and long-term (1-6 years) post-procedure complications were evaluated. RESULTS The success rates for stone removal and early complication rates were similar for both groups. The frequency of stone recurrence was approximately 4-fold higher in the endoscopic papillary balloon dilation group (25%) vs. the endoscopic sphincterotomy group (6.3%) at mid-term evaluation. However, over the long term, Kaplan-Meier estimated probability of stone recurrence tended to be higher in the endoscopic sphincterotomy group vs. the endoscopic papillary balloon dilation group; recurrent stones were found in, respectively, 26.7% vs. 6.3%. Complications occurred in 7 patients in each group. CONCLUSIONS Long-term outcome of endoscopic papillary balloon dilation for bile duct stone removal is satisfactory, provided that consideration is given to recurrence of stones by early follow-up evaluation.

Abstract
OBJECTIVE Our study describes the percutaneous expulsion of bile duct calculi into the duodenum by dilating the papilla with a balloon catheter. SUBJECTS AND METHODS. Patients (n = 212; 101 men and 111 women; mean age, 73 years; range, 31-95 years) had their calculi (single, 131; multiple, 81) percutaneously expelled into the duodenum in 73 patients via an indwelling T tube, and in 139 via transhepatic or transcystic duct route. Stone expulsion was facilitated with an occlusion balloon after balloon sphincteroplasty and with prior mechanical fragmentation in only 37 patients. After the expulsion of the calculi into the duodenum, drainage of the main bile duct to the exterior was maintained for 2-8 days. RESULTS Technical success was initially 90.4%, increasing to 93% at the second attempt. There were 13 failures due to the large size of the calculi in nine patients, excessive tortuosity of the T tube (Kher tube) in one, and breaches of the established protocol in two. Residual lithiasis was resolved in 98.6% of cases, decreasing to 92% in the group of native, or nonresidual, lithiasis. There were 10 major complications (hemobilia) with three cases of poor clinical outcome: hepatic necrosis, multiorgan failure, or death. CONCLUSION Percutaneous anterograde evacuation of bile duct stones with dilatation of the papilla using an angioplasty catheter and assisted with an occlusion balloon to expel the calculi is a cost-effective, nontraumatic, and safe procedure that retains the anatomic and functional integrity of the sphincter. It is a viable alternative procedure in the treatment of bile duct lithiasis.

Abstract
Adverse outcomes of endoscopic retrograde cholangiopancreatography (ERCP) include technical failures and complications. Complications cause significant morbidity to patients and anxiety to endoscopists. The key to preventing complications is to understand which patients and procedures are at highest risk so that appropriate decisions can be made as to whether ERCP should be performed at all, and if so, how. Patients who need ERCP the least are often the ones most likely to develop complications. For marginal indications, ERCP should be avoided. Success rates are higher and complication rates lower for endocopists performing large numbers by endoscopists with adequate experience.

Abstract
BACKGROUND The long-term outcome for patients after endoscopic sphincter of Oddi dilation is poorly documented. This study investigates the recurrence rate for bile duct stones in patients followed for 1 year or more after endoscopic sphincter dilation and stone extraction, and assessed prognostic factors associated with recurrence of ductal calculi. METHODS A total of 169 patients with bile duct stones were treated with endoscopic sphincter dilation between July 1998 and August 2001. Follow-up studies consisted of periodic biochemical tests and out-patient evaluations with endoscopic retrograde cholangiography or magnetic resonance cholangiography performed when follow-up exceeded 1 year. Putative risk factors for stone recurrence included gender, age, stone size and number, associated peripapillary diverticulum, gallbladder status, color of bile duct stones, and bile duct diameter. Statistical analysis consisted of both a Kaplan-Meier estimation and a multivariate Cox regression model. RESULTS Complete stone clearance was achieved in 162 (95.8%) patients, of whom 151 were followed (13 patients died from unrelated disorders). Mean follow-up was 23 months. Stone recurrence was documented in 13 patients. Patients with dilated bile duct or peripapillary diverticulum were at high risk for recurrence. CONCLUSIONS The interval between treatment of bile duct stones by endoscopic sphincter dilation and the recurrence of biliary calculi is relatively short. Bile duct size and peripapillary diverticula are risk factors for early recurrence.

Abstract
Complications and technical failures of endoscopic retrograde cholangiopancreatography (ERCP) cause significant morbidity and, occasionally, mortality. An understanding of patient- and procedure-related risks is important for decision making with regard to whether or how ERCP should be performed. Instances in which ERCP is the least clearly indicated are often the most likely to cause complications. Patient-related risk factors include suspected sphincter of Oddi (SO) dysfunction, female sex, normal serum bilirubin, or previous history of post-ERCP pancreatitis, with multiple risk factors conferring especially high risk. Technique-related risk factors include difficult cannulation, pancreatic contrast injection, balloon sphincter dilation, and precut sphincterotomy performed by endoscopists of varied experience. Pancreatic stents may reduce the risk of pancreatitis in a number of settings including SO dysfunction. Hemorrhage and perforation are rare and can be avoided with endoscopic technique and attention to the patient's coagulation status. Cholangitis is avoidable with adequate biliary drainage. Because success rates are higher and complication rates lower for endoscopists performing large volumes of ERCP, ERCP should be concentrated as much as possible among endoscopists with adequate experience. Patients with a high risk for complications may be best served by referral to an advanced center.

Abstract
BACKGROUND Although endoscopic papillary balloon dilation may result in acute pancreatitis or hyperamylasemia, the risk factors for these complications have not been well documented. Risk factors predictive of acute pancreatitis and hyperamylasemia after endoscopic papillary balloon dilation were retrospectively analyzed. METHODS In 118 patients who underwent endoscopic papillary balloon dilation for choledocholithiasis, postendoscopic papillary balloon dilation acute pancreatitis and hyperamylasemia (at least 3-fold elevation) were investigated. A multivariate analysis was conducted for 20 potential risk factors related to clinical and procedure characteristics. RESULTS Bile duct clearance was achieved in 113 patients. Early complications in the form of mild pancreatitis occurred in 7 patients (6%). Multivariate analysis identified history of acute pancreatitis as the only risk factor for postendoscopic papillary balloon dilation pancreatitis. Postendoscopic papillary balloon dilation hyperamylasemia occurred in 30 patients (25%). Multivariate analysis identified 4 independent risk factors for hyperamylasemia: an age of 60 years or less, previous pancreatitis, bile duct diameter 9 mm or less, and difficult bile duct cannulation. CONCLUSIONS Endoscopic papillary balloon dilation is associated with a relatively low occurrence (6%) of pancreatitis but a high frequency (25%) of hyperamylasemia. The latter may represent pancreatic irritation or latent pancreatic injury. Particular care is necessary when endoscopic papillary balloon dilation is performed in younger patients, those with a history of pancreatitis, patients with a nondilated bile duct, and when cannulation is difficult.

Abstract
BACKGROUND Endoscopic papillary balloon dilation (EPBD) for removal of bile duct stones tends to preserve papillary function. However, EPBD may exert beneficial or deleterious effects on gallbladder motility. This was a prospective, medium-term investigation (2 years) of the effects of EPBD on gallbladder motility. METHODS Twelve patients with intact gallbladders (6 with and 6 without gallbladder stones) who underwent EPBD for choledocholithiasis were enrolled in this study. Gallbladder motility was examined before EPBD and at 7 days, 1 month, 1 year, and 2 years after EPBD. Gallbladder volumes, measured after fasting and after ingestion of dried egg yolk, were determined by US. RESULTS All patients were asymptomatic during the 2-year follow-up period. Before EPBD, particularly in patients with cholelithiasis, the gallbladder had a larger fasting volume and lower yolk-stimulated maximum contraction compared with normal control subjects. Seven days after EPBD, fasting volume was decreased and maximum contraction was increased, both significantly compared with pre-EPBD values and regardless of the presence or absence of gallbladder stones. At 1 month, 1 year, and 2 years after EPBD, these changes were far less evident and gallbladder function did not differ significantly from baseline. CONCLUSION EPBD does not adversely affect gallbladder motility in the medium-term (2 years). In terms of gallbladder motility, EPBD does not appear to increase the future risk of acute cholecystitis or gallbladder stone formation.

Abstract
BACKGROUND AND AIM Endoscopic balloon sphincteroplasty (EBS) is an alternative to sphincterotomy for the treatment of bile duct stones. The purpose of this study was to determine if epinephrine irrigation of the papilla can prevent the pancreatic damage associated with EBS. METHODS A total of 173 patients with bile duct stones were treated by EBS. After conventional endoscopic retrograde cholangiography, EBS was performed by using a biliary dilatation catheter (balloon diameter: 8 mm). The duct was then cleared by using Dormia baskets or retrieval balloon catheters. Mechanical lithotripsy was performed before extraction when the stones were greater than 8 mm in diameter. In 81 patients, the dilated orifice was irrigated with 40-120 mL (50 +/- 37 mL) of 1:1,000,000 epinephrine (epinephrine group). In the remaining 92 patients, epinephrine irrigation was not performed (control group). Acute pancreatitis was defined by a serum amylase concentration fivefold greater than the upper limits of normal in association with abdominal pain. RESULTS After EBS, serum amylase concentrations were significantly increased in both groups. However, the degree of hyperamylasemia was less in the epinephrine group than in the control group (617 +/- 611 vs 1037 +/- 1491 IU/L, P < 0.05). The incidence of pancreatitis was lower in the epinephrine group than in the control group (1.2 vs 7.6%, P < 0.05). CONCLUSIONS Epinephrine irrigation is a simple and useful method to prevent post-EBS pancreatic damage and pancreatitis.

Abstract
BACKGROUND Endoscopic balloon dilation is under investigation as a treatment modality for bile duct stones. It may have an advantage of preserving the sphincter of Oddi function, but little is known about sphincter of Oddi cyclic motility after dilation. METHODS Four dogs with a duodenal cannula underwent sphincter of Oddi dilation and repeated manometry to assess sphincter of Oddi cyclic motility until 3 months after dilation. Histologic changes in the sphincter of Oddi were examined in another group of four dogs. RESULTS Motility index (sum of amplitude of sphincter of Oddi phasic waves counted per minute) and basal pressure decreased on day 3. Sphincter of Oddi amplitude during phase III of the duodenal migrating motor complex tended to be increased on day 3 and decreased to the minimum on day 21. Thereafter, it gradually recovered to baseline. By histology, severe acute inflammation was present in the sphincter of Oddi muscle layer on day 3. However, basal pressure remained significantly low even 3 months after dilation. CONCLUSIONS Sphincter of Oddi amplitude is incompletely reduced on day 3 after balloon dilation. Sphincter of Oddi basal pressure and motility index in the early phase of sphincter of Oddi cyclic motility remain low for at least 3 months after dilation. Further long-term follow-up is necessary to determine whether sphincter of Oddi function is actually preserved.

Abstract
OBJECTIVE The purpose of this study was to describe a technique for percutaneous bile duct stone clearance by pushing the stones into the small bowel after balloon dilation of the papilla. SUBJECTS AND METHODS During a 2-year period, 38 patients were treated percutaneously for stones in the biliary tree. Twenty-one patients were treated through a T tube or transcystic tract. Seventeen patients were treated through a transhepatic tract. Twenty-three patients had one stone each. Eight patients had two stones, and seven patients had three or more calculi. Stone size ranged from 3 to 16 mm in diameter (mean size, 6.7 nm). Balloon diameter based on the transverse diameter of the stones ranged from 7 to 18 mm (mean, 6.7 mm). An 11.5-mm occlusion balloon was used for pushing the stones through a 7- to 9-French vascular introducer. A catheter was left in the common bile duct from 1 to 6 days for external drainage. RESULTS The technique was successfully used for clearance of stones in 36 (94.7%) of the 38 patients. With 29 patients, the procedure was performed with only one attempt. Two attempts were necessary for five patients, and three attempts were necessary for four patients. Two major complications were cholangitis and biliary pleural effusion. No deaths were related to the procedure. CONCLUSION Percutaneous bile duct stone clearance by dilation of the papilla and evacuation of the stones in an antegrade fashion with an occlusion balloon is a safe and effective technique. It can be an alternative to basketing stones in selected patients.

Management of unsuspected common bile duct stones found during laparoscopic cholecystectomy by means of transcystic catheter placement and papillary dilation. Gastrointest Endosc 1999; 50:837-40.

Abstract
BACKGROUND The optimal treatment strategy for treatment of bile duct stones first diagnosed during laparoscopic cholecystectomy has not been established. We prospectively treated unsuspected bile duct stones by means of intraoperative placement of a transcystic catheter followed by postoperative pharmacologic papillary dilation or endoscopic papillary balloon dilation. METHODS In 17 patients with bile duct stones first found at laparoscopic cholecystectomy, a catheter was introduced via the cystic duct into the bile duct. If postoperative cholangiography via a transcystic catheter showed stones 5 mm or less in diameter, glyceryl trinitrate was infused via the catheter into the bile duct. Patients in whom medical dilation was unsuccessful or who had larger stones underwent endoscopic papillary balloon dilation. RESULTS Stone diameter measured 3 to 11 mm (mean 6.4 mm). Postoperative cholangiography revealed spontaneous passage in four patients. After pharmacologic papillary dilation, two of five patients with stones 5 mm or less in diameter had stone clearance. The remaining 11 patients underwent successful endoscopic papillary balloon dilation with stone clearance. In two patients, a guidewire introduced via a transcystic catheter through the papilla facilitated selective biliary cannulation. One early minor complication occurred. All patients remained without symptoms for a mean follow-up of 13 months. CONCLUSION For unsuspected bile duct stones (usually small ones), this strategy is a simple and effective alternative to laparoscopic bile duct exploration and postoperative sphincterotomy and may minimize early and late complications. Transcystic catheterization ensures access to the bile duct, thereby avoiding endoscopic treatment failures.

Abstract
BACKGROUND Endoscopic sphincter dilation (ESD) is believed to successfully treat bile duct stones without serious procedure-related complications. METHODS We evaluated the efficacy, safety and limitations of this relatively new procedure in a consecutive series of patients to establish the clinical role of this modality for treating bile duct stones. One hundred and forty-three consecutive patients were treated by ESD between July 1995 and March 1998. The balloons used were a Maxforce 5-Fr or Olbert 5-Fr balloon-tipped catheter with a maximal diameter of 8 mm. Mechanical lithotriptor (ML) or extracorporeal shock wave lithotripsy (ESWL) were used when stones were large and/or numerous and a Dormia basket or retrievable balloon catheter was used to extract the stones entirely. Procedure-related symptoms and chemical data after the procedure were monitored during and after ESD at least until the following morning. To diagnose residual stones accurately, intraductal ultrasonography was routinely used. RESULTS Although the majority of patients complained of subtle pain during balloon inflation and demonstrated oozing during and after balloon inflation, the procedures were well tolerated. Complete stone extraction was achieved in 139 (97.2%) of the patients. Mechanical lithotriptor and ESWL were used to assist stone clearance in 79 (55.2%) and 23 (16.1%) patients, respectively. Mild pancreatitis occurred in six patients (4.2%). However, there were no other serious complications. Stone recurrence was identified in six patients and these stones were re-extracted by subsequent ESD procedures. CONCLUSIONS A high success rate for stone extraction and the relative safety of this procedure was confirmed. However, there was recurrence in a relatively high percentage of patients within a short period and this may be a forthcoming issue in ESD. Long-term follow-up observation and the establishment of countermeasures for stone recurrence seem to be essential.

Abstract
BACKGROUND Endoscopic papillary balloon dilation for treatment of bile duct stones is likely to preserve papillary function. However, endoscopic papillary balloon dilation may affect gallbladder motility. We investigated the effects of endoscopic papillary balloon dilation on gallbladder motility. METHODS Ten patients with an intact gallbladder (six with and four without gallbladder stones) who underwent endoscopic papillary balloon dilation for choledocholithiasis were studied. Gallbladder motility was examined before and 7 days and 1 month after endoscopic papillary balloon dilation. Gallbladder volume, while fasting and after dried egg yolk ingestion, was determined by ultrasonography. RESULTS Before endoscopic papillary balloon dilation, particularly in patients with gallbladder stones, the gallbladder showed significantly larger fasting volume and lower yolk-stimulated maximum contraction compared with control subjects. Seven days after endoscopic papillary balloon dilation, fasting volume was decreased and maximum contraction was increased, regardless of the presence of gallbladder stones, with significant differences from the values before endoscopic papillary balloon dilation. One month after endoscopic papillary balloon dilation, these changes were reduced and gallbladder function did not differ significantly from baseline. CONCLUSIONS After endoscopic papillary balloon dilation, gallbladder motility improves transiently at 7 days but returns to baseline at 1 month. In terms of gallbladder motility, endoscopic papillary balloon dilation does not seem to increase the subsequent risk of acute cholecystitis.
