Abstract
BACKGROUND Clinically, common bile duct (CBD) stones >2 cm are difficult to remove by endoscopic retrograde cholangiopancreatography (ERCP). To evaluate this observation, the rates of successful clearance of CBD stones and complications were compared between ERCP extraction of CBD stones of >2 cm and <2 cm in diameter. METHODS All patients who had undergone endoscopic extraction of CBD stones at the Endoscopy Center of Shanghai First People's Hospital from May 2004 to May 2008 were reviewed. Patients with CBD stones of >2 cm in diameter were enrolled in the >2 cm group. Two matched controls with CBD stones of <2 cm in diameter were selected for each enrolled patient (<2 cm group). Patient characteristics, success rates, and complications during and after ERCP were compared. RESULTS Seventy-two patients constituted the >2 cm group and 144 patients were in the <2 cm group. No significant differences were found in the patient characteristics, except for stone size and CBD diameter. Both the overall success rate and the success rate in the first ERCP session were lower in the >2 cm group (77.8% and 58.3%, respectively) than in the <2 cm group (91.7% and 83.3%, P<0.01). During ERCP, the incidence of hypoxemia (30.6%) and hemorrhaging papillae (18.1%) in the >2 cm group was higher than in the <2 cm group (13.2% and 6.3%, P<0.05). After ERCP, the rates of delayed papillae hemorrhage (13.9%), hyperamylasemia (23.6%), acute pancreatitis (8.3%) and biliary infection (18.1%) were higher in the >2 cm group than in the <2 cm group (3.5%, 11.1%, 2.1%, and 2.8%, respectively, P<0.05). CONCLUSION The success rate of endoscopic extraction of CBD stones of >2 cm in diameter was lower but the complication rate was higher than that of stones of <2 cm in diameter.

Abstract
BACKGROUND Complications of the biliary tract after liver transplantation are successfully managed with ERCP; however, the incidence and risk factors for post-ERCP complications remain unknown. OBJECTIVE To examine the incidence, risk factors, and short-term outcome of post-ERCP complications in liver transplant (LT) recipients. DESIGN Retrospective evaluation of all ERCPs performed in LT recipients at our institution during a 7-year, 4-month period. SETTING Tertiary referral center. PATIENTS A total of 243 ERCPs performed in 121 LT recipients with duct-to-duct anastomosis. MAIN OUTCOME MEASUREMENTS Incidence of post-ERCP complications. Predictive factors were determined by univariate and multivariate analyses. RESULTS Overall complications occurred in 22 procedures (9%) (13 mild, 9 moderate): pancreatitis in 9 patients (3.7%), cholangitis in 8 patients (3.3%), postsphincterotomy bleeding in 4 patients (1.6%), and subcapsular hematoma in 1 patient (0.4%). The mean hospitalization for post-ERCP complications was 4.8 days (range 2-11 days). Logistic regression identified mammalian target of rapamycin inhibitors (odds ratio [OR], 4.65; 95% CI, 1.01-21.81; P = .049), serum creatinine level greater than 2 mg/dL (OR, 4.17; 95% CI, 1.07-16.26; P = .04), biliary sphincterotomy (OR, 3.03; 95% CI, 1.07-8.53; P = .037), and more than 2 pancreatic duct contrast injections (OR, 2.95; 95% CI, 1.10-7.91; P = .032) as independent risk factors for post-ERCP complications, whereas steroid therapy (OR, 0.23; 95% CI, 0.08-0.63; P = .004) was an independent protective factor. LIMITATIONS Single-center retrospective study. CONCLUSIONS The rate of complications after ERCP in LT recipients seems to be similar to that of non-LT recipients. Complications in this analysis were more common in LT recipients receiving mammalian target of rapamycin inhibitors and those with renal failure, biliary sphincterotomy, and more than 2 pancreatic duct injections, whereas they were less common in those patients on steroid therapy.

Abstract
Since it was developed in 1992, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been widely used and has been adapted for gastrointestinal and perigastrointestinal lesions. A medical literature review to evaluate the role of EUS-FNA for diagnosis of solid pancreatic masses showed a 78-95% sensitivity, 75-100% specificity, 98-100% positive predictive value, 46-80% negative predictive value and a 78-95% accuracy. The reported complication rates of EUS-FNA for pancreatic solid masses were 0-2%, although the criteria for complications varied among the studies. Because of its high diagnostic yield and low complication rate, EUS-FNA is cost-effective and widely applicable for the diagnosis of solid pancreatic masses, and is the best initial and the preferred secondary method compared with other biopsy techniques, such as endoscopic retrograde cholangiopancreatography-guided biopsy, computed tomography/ultrasound-FNA and surgery. Although EUS-FNA is 'a nearly perfected procedure,' controversy remains, such as the most suitable diameter of the needle, the appropriate number of needle passes and the necessity of on-site cytopathological evaluation. Recently investigators reported that using molecular analysis of EUS-FNA samples can achieve a higher diagnostic efficacy. Further research is encouraged to optimize the EUS-FNA procedure to reach its maximum diagnostic yield for solid pancreatic masses.

Abstract
BACKGROUND Several studies have evaluated predictors for complications of endoscopic retrograde cholangiopancreatography (ERCP), but their relative importance is unknown. In addition, currently used blood tests to detect post-ERCP pancreatitis are inconsistent. The aim of this study was to determine predictors of post-ERCP complications that could discriminate between patients at highest and lowest risk of post-ERCP complications and to develop a model that is able to identify patients that can safely be discharged shortly after ERCP. METHODS In a single-center, retrospective analysis over the period 2002-2007, predictors of post-ERCP complications were evaluated in a multivariable analysis and compared with those identified from a literature review. A prognostic model was developed based on these risk factors, which was further evaluated in a prospective patient population. RESULTS From our retrospective analysis and literature review, we selected the eight most important risk factors for post-ERCP pancreatitis and cholangitis. In the prognostic model, the risk factors (precut) sphincterotomy, sphincter of Oddi dysfunction, younger age, female gender, history of pancreatitis, pancreas divisum, and difficult cannulation accounted for a score of 1 each, whereas primary sclerosing cholangitis (PSC) accounted for a score of 2. A sum score of 4 or more in the prognostic model was associated with a high risk of developing pancreatitis and cholangitis (27%; 6/22) in the prospective patient population, whereas a sum score of 3 or less was associated with a low to intermediate risk (8%; 20/252). CONCLUSIONS We identified specific patient- and procedure-related factors that are associated with post-ERCP complications. The prognostic model based on these factors is able to identify patients who can be safely discharged the same day after ERCP.

Abstract
The investigation and treatment of disorders of the human biliary tree depend considerably on invasive endoscopic and radiologic procedures. These are associated with a significant risk of complications, some of which can be fatal. This review looks at these complications through the lens of 40 years of publications in the medical literature, and identifies the strengths and weaknesses of their current classification, diagnosis, and treatment.

Abstract
BACKGROUND Clinicians must choose a treatment strategy for patients with symptomatic cholelithiasis without knowing whether common bile duct (CBD) stones are present. The purpose of this study was to determine the most cost-effective treatment strategy for patients with symptomatic cholelithiasis and possible CBD stones. STUDY DESIGN Our decision model included 5 treatment strategies: laparoscopic cholecystectomy (LC) alone followed by expectant management; preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by LC; LC with intraoperative cholangiography (IOC) ± common bile duct exploration (CBDE); LC followed by postoperative ERCP; and LC with IOC ± postoperative ERCP. The rates of successful completion of diagnostic testing and therapeutic intervention, test characteristics (sensitivity and specificity), morbidity, and mortality for all procedures are from current literature. Hospitalization costs and lengths of stay are from the 2006 National Centers for Medicare and Medicaid Services data. The probability of CBD stones was varied from 0% to 100% and the most cost-effective strategy was determined at each probability. RESULTS Across the CBD stone probability range of 4% to 100%, LC with IOC ± ERCP was the most cost-effective. If the probability was 0%, LC alone was the most cost-effective. Our model was sensitive to 1 health input: specificity of IOC, and 3 costs: cost of hospitalization for LC with CBDE, cost of hospitalization for LC without CBDE, and cost of LC with IOC. CONCLUSIONS The most cost-effective treatment strategy for the majority of patients with symptomatic cholelithiasis is LC with routine IOC. If stones are detected, CBDE should be forgone and the patient referred for ERCP.

Abstract
OBJECTIVE The introduction of non-invasive imaging for biliary-pancreatic diseases has changed the indications and volumes of endoscopic retrograde cholangiopancreatography (ERCP) over time. This study aimed to provide national figures on ERCP in Norway over the last decade. MATERIAL AND METHODS Data from four national surveys on ERCP activity collected from 1998 to 2009 at the surgical and medical departments of all Norwegian hospitals were analyzed for variations in volumes among centers, regions, and specialties over time. RESULTS A total of 42,260 procedures were reported (average 3842 procedures per year, range 3492-4632). The number of hospitals with ERCP decreased from 41 to 35 and the annual number of procedures decreased by 13% (from 4632 to 4036), but the number of ERCP endoscopists remained stable at ~100. The proportion of procedures performed by surgeons decreased from 40% to 32% (p < 0.001) during the first half of the study period; the number of gastrointestinal surgeons performing ERCP remained stable in the latter half (46% and 48% for 2004 and 2008, respectively). In 2004, 15 endoscopists signed up for a formal ERCP training program, including 8 (53%) surgeons. This number increased to 21 (48%) in 2008. A non-significant decrease in referrals (49% in 2002 vs. 35% in 2005) between various ERCP centers was reported. Regional variation in ERCP volumes leveled off during the study period. CONCLUSIONS Though the number of both procedures and hospitals performing ERCP in Norway decreased, the proportion of low-volume and high-volume centers remained steady. The proportion of procedures by gastroenterological surgeons decreased significantly, yet roughly half of the endoscopists in ERCP training programs are surgeons. Regional variation in the ERCP numbers appears to have diminished.

Abstract
BACKGROUND The Swedish Registry for Gallstone Surgery and ERCP (GallRiks) is the first nationwide Web-based quality registry for gallstone surgery and ERCP in the world. In this article we report data from 11,074 ERCPs performed in 2007 and 2008. OBJECTIVE The aim of this study is to present outcomes, safety data, and success rates of ERCPs performed in Sweden. DESIGN Data gathering from a medical record database. PATIENTS This study reviewed 11,074 ERCPs performed in 2007 and 2008. METHODS In GallRiks, data concerning surgery performed for gallstone disease as well as all ERCPs are recorded. The registry is approved by the Swedish Surgical Society and is based on an Internet platform with online data registration. The online program includes 30-day follow-up information as well as the opportunity to retrieve electronic reports on demand. The present data represent 76% of all ERCPs performed in Sweden in 2007 and 95% of those performed in 2008. The database also has been validated, indicating a complete match between the medical records and the database in 97.3% of ERCP cases. MAIN OUTCOME MEASUREMENTS Cannulation success and perioperative and postoperative complications. RESULTS A successful bile duct cannulation was achieved in 92% of the ERCPs performed. The presence of common bile duct stones was the predominant finding and was seen in 36.8% of examinations. Perioperative and postoperative complication rates were 2.5% and 9.8%, respectively. The rate of ERCP-induced pancreatitis was 2.7%, and the total 30-day mortality rate in the database was 5.9% but varied significantly among the different diagnostic groups. The indications for ERCP differed between high-volume and low-volume centers, indicating an adequate referral pattern of complex cases in Sweden. LIMITATIONS GallRiks registration is voluntary and thus not 100%. This makes selection bias a possibility. CONCLUSION ERCP is widely used at Swedish hospitals, with acceptable cannulation success rates and perioperative and postoperative complication rates similar to established standards. GallRiks is a population-based nationwide registry with good data validity and high inclusion rates regarding ERCPs.

Abstract
BACKGROUND Further studies evaluating the safety of advanced endoscopic procedures in elderly patients are needed. AIM To evaluate the safety of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) in the elderly. METHODS The study population, consisting of 1,000 patients who underwent ERCP or EUS, was divided into two cohorts. The elderly cohort consisted of patients ≥ 75 years old. The nonelderly cohort consisted of patients <75 years old. The data collected included demographic information, type of procedure completed, procedure medication used, and endoscopic intervention performed. Complications included any event which occurred during the procedure or up to 1 month post procedure. RESULTS A total of 600 ERCPs and 400 EUS were included. The mean age of the elderly cohort was 80 years (range 75-95 years, n = 184) versus 54 years (range 13-74 years, n = 816) for the nonelderly cohort. The ERCP complication rate was 10.0% in the elderly versus 10.6% (P = 1.0) for the nonelderly. The EUS complication rate was 4.8% in the elderly versus 3.1% in the nonelderly (P = 0.49). The overall complication rates were identical at 7.6% (P = 1.0). Sedation doses were lower for the elderly cohort (P < 0.001). There was a higher rate of procedure bleeding in the elderly cohort (P = 0.016). CONCLUSION Advanced age is not a contraindication for advanced endoscopic procedures. There is no significant increase in the rate of overall procedure-related complications seen with either ERCP or EUS in elderly patients; however, elderly patients have a higher risk of bleeding. Less procedure-related sedation medication is required for elderly patients.

Abstract
AIM: To investigate the value of endoscopic nasobiliary drainage (ENBD) in the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and hyperamylasemia in patients with common bile duct stones.
METHODS: The clinical data of 141 patients with common bile duct stones, including 65 undergoing ENBD and 77 undergoing routine treatment, were retrospectively reviewed. The efficacy and complication rate were compared between the two groups.
RESULTS: Serum amylase levels at 2 and 24 h postoperatively were significantly lower in the ENBD group than in the routine treatment group (67.3 U/L ± 9.1 U/L vs 98.3 U/L ± 11.2 U/L, 89.5 U/L ± 13.0 U/L vs 126.2 U/L ± 14.2 U/L, both P < 0.01). The incidence of post-ERCP pancreatitis and hyperamylasemia was also significantly lower in the ENBD group than in the routine treatment group.
CONCLUSION: ENBD can effectively prevent the occurrence of post-ERCP pancreatitis and hyperamylasemia in patients with common bile duct stones.

Abstract
The aim of this article is to review the literature regarding post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. We searched for and evaluated all articles describing the diagnosis, epidemiology, pathophysiology, morbidity, mortality and prevention of post-ERCP pancreatitis (PEP) in adult patients using the PubMed database. Search terms included endoscopic retrograde cholangiopancreatography, pancreatitis, ampulla of vater, endoscopic sphincterotomy, balloon dilatation, cholangiography, adverse events, standards and utilization. We limited our review of articles to those published between January 1, 1994 and August 15, 2009 regarding human adults and written in the English language. Publications from the reference sections were reviewed and included if they were salient and fell into the time period of interest. Between the dates queried, seventeen large (> 500 patients) prospective and four large retrospective trials were conducted. PEP occurred in 1%-15% in the prospective trials and in 1%-4% in the retrospective trials. PEP was also reduced with pancreatic duct stent placement and outcomes were improved with endoscopic sphincterotomy compared to balloon sphincter dilation in the setting of choledocholithiasis. Approximately 34 pharmacologic agents have been evaluated for the prevention of PEP over the last fifteen years in 63 trials. Although 22 of 63 trials published during our period of review suggested a reduction in PEP, no pharmacologic therapy has been widely accepted in clinical use in decreasing the development of PEP. In conclusion, PEP is a well-recognized complication of ERCP. Medical treatment for prevention has been disappointing. Proper patient selection and pancreatic duct stenting have been shown to reduce the complication rate in randomized clinical trials.

Abstract
BACKGROUND AND AIMS Drug-induced pancreatitis accounts for about 2% of acute pancreatitis. The aim of this study is to determine whether propofol and other medications are associated with increased risk for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. METHODS A retrospective study was conducted at a single tertiary care hospital. All patients who underwent ERCP from 2001 to 2004 were included. Diagnosis of acute post-ERCP pancreatitis was based on a consensus definition. RESULTS A total of 506 patients underwent ERCP. The total incidence of post-ERCP pancreatitis was 7.1%. There was no significant difference in post-ERCP pancreatitis between patients who received propofol compared to patients who received midazolam and fentanyl (9.0 vs. 5.9%, p = 0.18). Patients receiving an angiotensin receptor blocker were approximately 4 times more likely to develop post-ERCP pancreatitis (OR = 4.1, 95% CI 1.6-10.9). Patients younger than 65 years and smokers also had higher risk of developing acute post-ERCP pancreatitis than those who were older than 65 years (OR = 3.9, 95% CI 1.7-9.1) and non-smokers (OR = 2.8, 95% CI 1.3-6.2). CONCLUSIONS Propofol is a safe sedative drug for ERCP without additional risk of developing acute post-ERCP pancreatitis. Use of angiotensin receptor blockers, smoking and younger age are independent risk factors for post-ERCP pancreatitis.

Endoscopic retrograde cholangiopancreatography is useful and safe in children. J Pediatr Surg 2010; 45:938-42. [PMID: 20438931 DOI: 10.1016/j.jpedsurg.2010.02.009] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2010] [Accepted: 02/02/2010] [Indexed: 12/19/2022]
Abstract
PURPOSE Endoscopic retrograde cholangiopancreatography (ERCP) is a recognized diagnostic and therapeutic tool in the adult population. Its use in children has been more common in the last years. There are little data on safety and usefulness of that procedure in children. The aim of this study was to review the experience with ERCP in a tertiary university center dedicated to children. METHOD We conducted a retrospective chart review of patients seen at the Centre Hospitalier Universitaire Ste-Justine (Montreal, Quebec, Canada) who had undergone an ERCP between September 1990 and July 2007. Data on demographics, diagnosis, anesthesia type, treatments, and complications were collected. RESULTS Thirty-eight ERCPs were performed on 29 patients. There were 21 girls (72%), and median age at time of procedure was 10.3 years old (range, 3-17 years). Most had only one procedure performed. Two children had 2 interventions, and 1 child with papillary stenosis had 8 interventions linked to stent treatment. The ampulla was cannulated, and the procedure was successfully completed in 97% (37/38) of cases. General anesthesia and sedation were performed in 74% and 26% of procedures, respectively. Indications for ERCP were 29 recurrent or chronic pancreatitis (76%), 8 common bile duct obstructions (21%), and 1 choledochal cyst (3%). Endoscopic treatment was done in 29% of cases. The complication rate was 13.5%, and 4 clinical acute pancreatitis resolved with conservatory treatment. No severe pancreatitis, perforation, or bleeding was noted. Of the patients, 79% had their follow-up at the Centre Hospitalier Universitaire Ste-Justine for a median length of 43 months (range, 1-53 months). CONCLUSION Endoscopic retrograde cholangiopancreatography is used as a diagnostic and therapeutic procedure in children with a complication rate similar to that seen in adults. The need for general anesthesia is much more frequent with children. When performed by well-trained endoscopists, ERCP is useful and safe in children.

Abstract
INTRODUCTION Common bile duct (CBD) stones can cause serious morbidity or mortality, and evidence for them should be sought in all patients with symptomatic gallstones undergoing cholecystectomy. Routine intra-operative cholangiography (IOC) involves a large commitment of time and resources, so a policy of selective cholangiography was adopted. This study prospectively evaluated the policy of selective cholangiography for patients suspected of having choledocholithiasis, and aimed to identify the factors most likely to predict the presence of CBD stones positively. PATIENTS AND METHODS Data from 501 consecutive patients undergoing laparoscopic cholecystectomy (LC) for symptomatic gallstones, of whom 166 underwent IOC for suspected CBD stones, were prospectively collected. Suspicion of choledocholithiasis was based upon: (i) deranged liver function tests (past or present); (ii) history of jaundice (past or present) or acute pancreatitis; (iii) a dilated CBD or demonstration of CBD stones on imaging; or (iv) a combination of these factors. Patient demographics, intra-operative findings, complications and clinical outcomes were recorded. RESULTS Sixty-four cholangiograms were positive (39%). All indications for cholangiogram yielded positive results. Current jaundice yielded the highest positive predictive value (PPV; 86%). A dilated CBD on pre-operative imaging gave a PPV of 45% for CBD calculi; a history of pancreatitis produced a 26% PPV for CBD calculi. Patients with the presence of several factors suggestive of CBD stones yielded higher numbers of positive cholangiograms. Of the 64 patients having a laparoscopic common bile duct exploration (LCBDE), four (6%) required endoscopic retrograde cholangiopancreatography (ERCP) for retained stones (94% successful surgical clearance of the common bile duct) and one (2%) for a bile leak. Of the 335 patients undergoing LC alone, three (0.9%) re-presented with a retained stone, requiring intervention. There were 12 (7%) requiring conversion to open operation. CONCLUSIONS A selective policy for intra-operative cholangiography yields acceptably high positive results. Pre-operatively, asymptomatic bile duct stones rarely present following LC; thus, routine imaging of the biliary tree for occult calculi can safely be avoided. Therefore, a rationing approach to the use of intra-operative imaging based on the pre-operative indicators presented in this paper, successfully identifies those patients with bile duct stones requiring exploration. Laparoscopic bile duct exploration, performed by an experienced laparoscopic surgeon, is a safe and effective method of clearing the bile duct of calculi, with minimal complications, avoiding the necessity for an additional intervention and prolonged hospital stay.

Abstract
PURPOSE This study compared the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography (EUS) in evaluating the cause of extrahepatic bile duct dilatation. MATERIALS AND METHODS Forty-five patients (26 men, mean age 57 years) with extrahepatic biliary dilatation, as shown by transabdominal ultrasound, with or without elevated biliary and pancreatic serum indices, were prospectively studied with MRCP and EUS between September 2007 and October 2008. EUS and MRCP were performed within no more than 24 h of each other to reduce the possibility of changes due to stone migration. Image analysis was carried out in a double-blind fashion. RESULTS MRCP had 88.9% diagnostic accuracy, 91.9% sensitivity and 75% specificity, with 94.4% positive predictive value and 66.7% negative predictive value. EUS had 93.3% diagnostic accuracy, 97.3% sensitivity and 75% specificity; the positive and negative predictive values were 94.7% and 85.7%, respectively. CONCLUSIONS MRCP and EUS do not show significant statistical differences in diagnostic accuracy. MRCP is an accurate, noninvasive modality in the study of extrahepatic biliary pathology. EUS is especially reliable in patients with extrahepatic biliary obstruction caused by endoluminal sludge.

Abstract
BACKGROUND The benefits of preoperative biliary drainage, which was introduced to improve the postoperative outcome in patients with obstructive jaundice caused by a tumor of the pancreatic head, are unclear. METHODS In this multicenter, randomized trial, we compared preoperative biliary drainage with surgery alone for patients with cancer of the pancreatic head. Patients with obstructive jaundice and a bilirubin level of 40 to 250 micromol per liter (2.3 to 14.6 mg per deciliter) were randomly assigned to undergo either preoperative biliary drainage for 4 to 6 weeks, followed by surgery, or surgery alone within 1 week after diagnosis. Preoperative biliary drainage was attempted primarily with the placement of an endoprosthesis by means of endoscopic retrograde cholangiopancreatography. The primary outcome was the rate of serious complications within 120 days after randomization. RESULTS We enrolled 202 patients; 96 were assigned to undergo early surgery and 106 to undergo preoperative biliary drainage; 6 patients were excluded from the analysis. The rates of serious complications were 39% (37 patients) in the early-surgery group and 74% (75 patients) in the biliary-drainage group (relative risk in the early-surgery group, 0.54; 95% confidence interval [CI], 0.41 to 0.71; P<0.001). Preoperative biliary drainage was successful in 96 patients (94%) after one or more attempts, with complications in 47 patients (46%). Surgery-related complications occurred in 35 patients (37%) in the early-surgery group and in 48 patients (47%) in the biliary-drainage group (relative risk, 0.79; 95% CI, 0.57 to 1.11; P=0.14). Mortality and the length of hospital stay did not differ significantly between the two groups. CONCLUSIONS Routine preoperative biliary drainage in patients undergoing surgery for cancer of the pancreatic head increases the rate of complications.

Abstract
The objective of this research paper is to evaluate the effect of prophylactic nitroglycerin in the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) by performing a meta-analysis of randomized controlled trials (RCTs). Electronic databases, including PubMed, EMBASE, the Cochrane library, and the Science Citation Index, were searched to retrieve relevant trials. Outcome measures were the incidence of PEP. Four RCTs, enrolling a total of 856 patients, were included. Meta-analysis of these trials indicated a significant association between the use of nitroglycerin and the reduction of PEP (RR 0.60; 95%CI: 0.39-0.92; P = 0.02). However, subsequent sensitive analysis failed to confirm that nitroglycerin was statistically superior to a placebo in reducing PEP (RR 0.68; 95%CI: 0.41-1.11; P = 0.12). Based on the limitations in this meta-analysis, prophylactic use of nitroglycerine for all patients who underwent ERCP is not recommended. Further clinical trials are required to confirm the effect of nitroglycerin in the prevention of PEP.

Abstract
BACKGROUND Duodenal perforations during diagnostic upper endoscopy are rare; however, when therapeutic techniques are performed, the reported incidence is as great as 2.8%. Surgical repair is usually mandated, but it is associated with significant morbidity and mortality. OBJECTIVE To compare closure of duodenal perforations by using an over-the-scope clip (OTSC) with a surgical closure. DESIGN Randomized, controlled animal study. SETTING Animal facility laboratory. ANIMALS Domestic pigs (24 females). INTERVENTIONS Large (10-mm) duodenal perforations were created by using an endoscopic needle-knife. The animals were randomly assigned to either open surgical repair (n=12) or endoscopic closure by using the OTSC system (n=12). Pressurized leak tests were performed during necropsy. MAIN OUTCOME MEASUREMENTS One major bleed occurred because of a liver injury during creation of the duodenotomy. Mean time for endoscopic closure was 5 minutes (range, 3-8 min; SD +/- 2). No complications occurred during any of the closure procedures. At necropsy, all OTSC and surgical closures demonstrated complete sealing of duodenotomy sites. Pressurized leak tests demonstrated a mean burst pressure of 166 mm Hg (range, 80-260; SD +/- 65) for OTSC closures and 143 mm Hg (range, 30-300, SD +/- 83) for surgical sutures. Ex vivo intact duodenal specimens exhibited a mean burst pressure of 247 mm Hg (range, 200-300; SD +/- 35), which was significantly higher compared with in vivo OTSC and surgical closures (P < .01). There were no significant differences between burst pressures of OTSC and surgical closures (P = .461). LIMITATIONS Nonsurvival setting. CONCLUSIONS Endoscopic closure of duodenal perforations by using the OTSC system is comparable with surgical closure in a nonsurvival porcine model. This technique is easy to perform and seems suitable for repairing duodenal perforations.

Abstract
Nowadays, minimally invasive surgery has been widely accepted, and a variety of endoscopic devices have been devised. The use of various endoscopic devices has resulted in a more rapid convalescence and a shorter hospital stay for many patients. Treatments for choledocholithiasis have been changed greatly from traditional exploratory choledochotomy and T- tube drainage to laparoscopic common bile duct exploration and primary duct closure, transcystic laparoscopic common bile duct exploration, or endoscopic extraction of common bile duct stones before and after laparoscopic cholecystectomy. Combined use of laparoscopy, duodenoscopy and choledochoscopy will be the trend of choledocholithiasis treatment in the future.

Abstract
BACKGROUND AND AIM The use of wire-guided cannulation (WGC) for prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is controversial. The aim of the present study was to assess the overall effect of WGC for PEP compared with conventional contrast-assisted cannulation by carrying out a meta-analysis of all available randomized controlled trials (RCT). METHODS Electronic databases, including PubMed, EMBASE, the Cochrane library and the Science Citation Index, were searched to retrieve relevant trials. In addition, meeting abstracts and the reference lists of retrieved articles were reviewed for further relevant studies. Outcome measures were the incidence of PEP. RESULTS Four RCT, enrolling a total of 1413 patients, were included. The meta-analysis failed to indicate a significant association between the use of WGC and the reduction of PEP (RR 0.34; 95% CI: 0.10-1.17; P = 0.09). Subgroup analysis including trials without cross-over design showed a significant benefit with the use of WGC in reducing PEP (RR 0.20; 95% CI: 0.09-0.40; P < 0.00001) and trials without precut used failed to indicate a significant differences between the two group (RR 0.38; 95% CI: 0.01-11.73; P = 0.58). CONCLUSIONS This meta-analysis showed only a non-significant reduction in the rate of PEP with the use of WGC. Further well-designed RCT are required to confirm the effect of WGC, especially in patients who were easier to cannulate.

Abstract
AIM: To compare the hemostatic efficacy between epinephrine injection alone and epinephrine injection combined with thermotherapy for delayed post-endoscopic sphincterotomy (ES) bleeding.
METHODS: Cases with delayed post-ES bleeding undergoing epinephrine injection alone (epinephrine injection group, n = 26) or epinephrine combined with thermotherapy (combination therapy group, n = 33) in our institution between 1999 and 2007 were retrospectively investigated. The main outcome measurements were: initial endoscopic hemostasis, re-bleeding, complications, requirement of angiographic embolization or surgery, requirement for blood transfusion, and mortality.
RESULTS: The initial hemostatic efficacy was 96.2% for epinephrine injection alone and 100% for combination therapy (P = 0.44). There were four patients with re-bleeding in each group (16.0% vs 12.1%, P = 0.72). There was only one complication of pancreatitis from the combination therapy group. Three patients (11.5%) in the epinephrine injection group and one patient (3%) in the combination therapy group required angiographic embolization or surgery (P = 0.31). The total number of blood transfusions was not significantly different between the two groups (3.5 ± 4.6 U vs 3.5 ± 4.5 U, P = 0.94). There was no bleeding-related death in either group.
CONCLUSION: Epinephrine injection alone is as effective as epinephrine injection combined with thermotherapy for the management of delayed post-ES bleeding.

Abstract
BACKGROUND There are no large studies documenting quality outcomes and complication rates of ERCP in community practice. The American Society for Gastrointestinal Endoscopy (ASGE)/American College of Gastroenterology Task Force on Quality proposed 5 questions regarding ERCP in community practice. The ASGE Committee on Outcomes Research recommended 8 ERCP-specific quality indicators be used to provide a better accounting of quality in ERCP. OBJECTIVE To determine ERCP quality outcomes, including complications, in a community practice. DESIGN Prospective study. SETTING Eight community hospitals in the Minneapolis-St. Paul, Minnesota, area. PATIENTS Every patient undergoing ERCP by Minnesota Gastroenterology PA from December 1, 2005, through July 31, 2006. MAIN OUTCOME MEASUREMENTS ASGE-recommended quality indicators, especially 30-day complication rates. RESULTS A total of 805 ERCP procedures were performed in 696 patients. Therapeutic ERCP accounted for 78.4%. The complication rate was 5.0% (5.7% of therapeutic and 2.3% of diagnostic procedures). Pancreatitis occurred in 3.2% of procedures (3.6% of therapeutic and 1.7% of diagnostic procedures). Infection (0.75%), hemorrhage (0.62%), and perforation (0.12%) only occurred after therapeutic ERCP. Cardiopulmonary complications occurred in 2 patients (0.25%). Precut sphincterotomy was performed in 26 cases (3.2%), and sphincter of Oddi manometry in 23 cases (2.9%). Success rates were 94.0% for biliary cannulation, 87.0% for stone extraction, and 90.2% for relieving biliary obstruction. A total of 530 patient satisfaction surveys were completed and revealed that the response to the question, "Would you have the procedure done again by this physician?" was the most sensitive indicator of patient satisfaction. CONCLUSIONS In this community practice, complication rates compare very favorably with those of academic centers. The technical success rates achieved or exceeded rates recommended by the ASGE/American College of Gastroenterology Task Force.

Abstract
Common bile duct stones (CBDSs) may occur in up to 3%–14.7% of all patients for whom cholecystectomy is preformed. Patients presenting with CBDS have symptoms including: biliary colic, jaundice, cholangitis, pancreatitis or may be asymptomatic. It is important to distinguish between primary and secondary stones, because the treatment approach varies. Stones found before, during, and after cholecystectomy had also differing treatments. Different methods have been used for the treatment of CBDS but the suitable therapy depends on conditions such as patient' satisfaction, number and size of stones, and the surgeons experience in laparoscopy. Endoscopic retrograde cholangiopancreatography with or without endoscopic biliary sphincterotomy, laparoscopic CBD exploration (transcystic or transcholedochal), or laparotomy with CBD exploration (by T-tube, C-tube insertion, or primary closure) are the most commonly used methods managing CBDS. We will review the pathophysiology of CBDS, diagnosis, and different techniques of treatment with especial focus on the various surgical modalities.

Abstract
BACKGROUND Complications of ERCP are an important concern. We sought to determine predictors of post-ERCP complications at our institution. METHODS GI TRAC is a comprehensive data set of patients who underwent ERCP at our institution from 1994 through 2006. Logistic regression models were used to evaluate 4 categories of complications: (1) overall complications, (2) pancreatitis, (3) bleeding, and (4) severe or fatal complications. Independent predictors of complications were determined with multivariable logistic regression. RESULTS A total of 11,497 ERCP procedures were analyzed. There were 462 complications (4.0%), 42 of which were severe (0.36%) and 7 were fatal (0.06%). Specific complications of pancreatitis (2.6%) and bleeding (0.3%) were identified. Overall complications were statistically more likely among individuals with suspected sphincter of Oddi dysfunction (SOD) (odds ratio [OR] 1.91) and after a biliary sphincterotomy (OR 1.32). Subjects with a history of acute or chronic pancreatitis (OR 0.78) or who received a temporary small-caliber pancreatic stent (OR 0.69) had fewer complications. Post-ERCP pancreatitis was more likely to occur after a pancreatogram via the major papilla (OR 1.70) or minor papilla (OR 1.54) and among subjects with suspected SOD with stent placement (OR 1.45) or without stent placement (OR 1.84). Individuals undergoing biliary-stent exchange had less-frequent pancreatitis (OR 0.38). Biliary sphincterotomy was associated with bleeding (OR 4.71). Severe or fatal complications were associated with severe (OR 2.38) and incapacitating (OR 7.65) systemic disease, obesity (OR 5.18), known or suspected bile-duct stones (OR 4.08), pancreatic manometry (OR 3.57), and complex (grade 3) procedures (OR 2.86). CONCLUSIONS This study characterizes a large series of ERCP procedures from a single institution and outlines the incidence and predictors of complications.

Abstract
Most perforations of the gastrointestinal tract during endoscopic retrograde cholangiopancreatography (ERCP) can be managed nonoperatively. Identifying patients who require operative management is problematic. A clinical endoscopy database was queried for patients who sustained ERCP perforation over a 13-year period. Records were reviewed and analyzed with approval of the Institutional Review Board. During the study period, 12,817 patients underwent ERCP; 24 (0.2%) had an endoscopic perforation. Twelve patients had a retroperitoneal perforation during sphincterotomy and all were successfully managed nonoperatively. Nine of these were undergoing treatment for sphincter of Oddi dysfunction. Twelve patients had perforation remote from the papilla. Of these, 10 required surgical intervention. Six patients had surgically altered anatomy (three postpancreaticoduodenectomy, three post-Billroth II gastrectomy) and one had situs inversus. Six of these seven required surgical intervention. Median length of stay of all patients was 7.5 days, morbidity was 25 per cent, and one patient died 16 days after surgery. Gut perforation after ERCP requires prompt surgical evaluation. Patients with sphincterotomy-related retroperitoneal perforation can be managed safely with nonoperative therapy in most instances. Patients with remote perforation usually need surgical intervention. Altered foregut anatomy leads to injuries that usually require operative management.

Abstract
BACKGROUND The aim of our study was to develop a system to grade the risk of the procedures summarized under the term endoscopic retrograde cholangiopancreatography (ERCP). METHODS In a controlled prospective study, we evaluated the early complications of ERCP in 526 consecutive patients at a single endoscopy center in a defined period. The relation between endoscopic procedures and related complications was analyzed for significance. A grading system based on significant risk factors and clinical implications was developed. RESULTS Of the ERCP procedures, 29% were diagnostic and 71% therapeutic. A total of 45 complications occurred in 42 patients: pancreatitis (2%), perforation (1%), cardiorespiratory problems (0.6%), stent-related complications (0.5%), leakages (1.5%), and bleeding (3%). A native papilla was a significant risk factor for the development of complications (P = 0.046). On the basis of these findings, we defined five groups of ERCP-related complications: nonnative papillae with either diagnostic (A) or therapeutic interventions (B); native papillae with diagnostic (C) or therapeutic (D) interventions; and special therapeutic interventions (E). Complication rates differed significantly between individual groups, A versus D (P = 0.013), A versus E (P = 0.010), B versus D (P = 0.005), and B versus E (P = 0.003), as well as between A/B and C/D (P = 0.003). CONCLUSIONS A grading system based on differentiating between native and nonnative papillae and diagnostic versus therapeutic procedures demonstrated significantly different complication rates. This grading system has the potential to predict the risk of ERCP-related complications.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound are invaluable tools in the diagnostic and therapeutic evaluation and management of a variety of pancreatobiliary disorders. Along with a significant refinement in the equipment and techniques used has come a recent trend toward aggressive therapeutic interventions. Because of the technical nature of these procedures and the characteristics of the patients, post-procedural complications may occur, ranging from minor (requiring brief hospitalization) to severe (causing permanent disability or death). This review summarizes these complications and outlines strategies to minimize them.

Abstract
BACKGROUND Given the limitations and risks associated with current treatments for common bile duct (CBD) stones, the authors placed a spontaneously removed endobiliary J stent in the distal CBD to decompress the biliary tract and performed a primary closure of the CBD after laparoscopic common bile duct exploration (LCBDE). METHODS In this study, 10 of 14 patients with a diagnosis of choledocholithiasis were successfully treated using LCBDE. After extraction of the CBD stones using a choledoscope, a J-shaped stent was placed into the distal CBD as an internal drainage. The J stent was fixed with a rapid absorbable suture at the choledochotomy, which was closed by primary suture. RESULTS The procedures for all 10 patients were successfully completed. No complications related to placement of the endobiliary J stents were observed postoperatively. None of the patients reported discomfort, and the J stents passed spontaneously 2 to 3 weeks after discharge. CONCLUSION Spontaneously removed endobiliary J-stent drainage is a safe and effective surgical technique that allows for straightforward postoperative management after LCBDE.

Abstract
OBJECTIVES Both endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography (EUS) are commonly performed in the evaluation of idiopathic pancreatitis. However, comparative trials of these modalities are lacking, and thus the ideal endoscopic diagnostic strategy to evaluate idiopathic pancreatitis remains unknown. METHODS A decision analysis model of patients with 2 attacks of idiopathic pancreatitis with gallbladder in situ was constructed using TreeAge software. We analyzed cost and overall diagnostic ability of 3 strategies, namely, EUS, ERCP with manometry and bile aspiration, and laparoscopic cholecystectomy. RESULTS Using the base case analysis, initial EUS was the preferred initial modality for the diagnosis. The expected cost for initial EUS was $4469 compared with $4615 for ERCP and $6268 for laparoscopic cholecystectomy. For cholecystectomy to be the preferred strategy, the total cost would need to be less than $1314, well below any realistic cost estimate. If the prevalence of microlithiasis/sludge was greater than 80%, then cholecystectomy would be preferred, whereas ERCP would be preferred with a prevalence of less than 41%. CONCLUSIONS This cost minimization study identifies EUS as the least costly initial test for the diagnostic evaluation of patients with idiopathic pancreatitis with gallbladder in situ.

Abstract
BACKGROUND Pancreatitis is the most common major complication of diagnostic and therapeutic ERCP. Platelet-activating factor (PAF) has been implicated in the pathophysiologic events associated with acute pancreatitis. Animal and human studies suggested that recombinant PAF acetylhydrolase (rPAF-AH) might ameliorate the severity of acute pancreatitis. OBJECTIVE Our purpose was to determine whether prophylactic rPAF-AH administration reduces the frequency or severity of post-ERCP pancreatitis in high-risk patients. DESIGN Randomized, multicenter, double-blind, placebo-controlled study. INTERVENTIONS Patients received rPAF-AH at a dose of either 1 or 5 mg/kg or placebo. Patients were administered a single intravenous infusion over 10 minutes of study drug or placebo <1 hour before ERCP. MAIN OUTCOME MEASUREMENTS Standardized criteria were used to diagnose and grade the severity of post-ERCP pancreatitis. Adverse events were prospectively recorded. RESULTS A total of 600 patients were enrolled. There were no statistically significant differences among the treatment groups with respect to patient demographics, ERCP indications, and patient and procedure risk factors for post-ERCP pancreatitis with the following exceptions: the rPAF-AH 5 mg/kg group had significantly fewer patients younger than 40 years old and scheduled to undergo a therapeutic ERCP involving the pancreatic sphincter or duct. Post-ERCP pancreatitis occurred in 17.5%, 15.9%, and 19.6% of patients receiving rPAF-AH (1 mg/kg), rPAF-AH (5 mg/kg), and placebo, respectively (P = .59 for rPAF-AH 1 mg/kg vs placebo and P = .337 for rPAF-AH 5 mg/kg vs placebo). There was no statistically significant difference between the groups with regard to the severity of pancreatitis, frequency of amylase/lipase elevation more than 3 times normal, or abdominal pain. CONCLUSIONS There was no apparent benefit of rPAF-AH treatment compared with placebo in reducing the incidence of post-ERCP pancreatitis in subjects at increased risk.

Abstract
BACKGROUND Factors affecting diagnostic accuracy and comparison of patients in the follow-up period for negative outcomes are not thoroughly investigated in a randomized trial. OBJECTIVE Our purpose was to compare diagnostic accuracy, complications, and number of interventions. DESIGN Prospective, unicentric, single-blind, randomized study. SETTING Single tertiary referral university hospital. PATIENTS One hundred twenty patients with intermediate risk for common bile duct (CBD) stones were randomized to either an EUS-first, endoscopic retrograde cholangiography (ERC)-second (n = 60) versus an ERC-only (n = 60) procedure. INTERVENTIONS EUS, ERC, sphincterotomy, and balloon sweeping of CBD when needed. MAIN OUTCOME MEASUREMENTS Sensitivity of EUS versus ERC, factors affecting diagnostic capability, complications, total number of endoscopic procedures. RESULTS The sensitivity and specificity of ERC were 75% (95% CI, 42%-93%) and 100% (95% CI, 95%-100%), respectively. The sensitivity and specificity of EUS were 91% (95% CI, 59%-99%) and 100% (95% CI, 95%-100%), respectively. EUS is more sensitive than ERC in detecting stones smaller than 4 mm (90% vs 23%, P < .01). Although not significant, there was a trend for an increased number of endoscopic procedures in the ERC group compared with the EUS group (98 vs 83). The post-ERC pancreatitis rate was 6 in 120 (5%) in all study patients, and the post-ERC pancreatitis rate in patients with an undilated CBD was 5 of 53 (9.43%). The independent factors for post-ERC pancreatitis are undilated CBD (risk ratio [RR] 6.320; 95% CI, 1.703-11.524, P = .009), allocation into the ERC group (RR 2.107; 95% CI, 1.330-3.339, P = .02), female sex (RR 1.803; 95% CI, 1.155-2.813, P = .03), and age less than 40 years (RR 1.888; 95% CI, 1.245-2.863, P = .01). Kaplan-Meier analysis revealed higher rate of negative outcome in the ERC group than in the EUS group (P = .049, log-rank test). CONCLUSION The EUS-first approach is not associated with further risk for subsequent endoscopic procedures. Patients with an undilated CBD should be investigated by the EUS-first approach to prevent post-ERC pancreatitis.

Abstract
BACKGROUND To the authors' knowledge, little information is available regarding the incidence of cholecystitis among patients with cancer. METHODS The authors conducted a population-based historical cohort study of 51,228 patients with incident cancer, identified in medical databases of western Denmark between 1995 and 2003. A general population comparison cohort of 512,280 persons was assembled using the Danish Civil Registration System. The occurrence of cholecystitis in the 2 groups was determined by linkage to the regional Hospital Discharge Registry. RESULTS In all, 230 incident diagnoses of cholecystitis were identified in the cancer cohort during 130,185 person-years (median follow-up time: 1.6 years), corresponding to an incidence rate of 1.8 of 1000 person-years. After adjustment for confounders, the relative risk (RR) for cholecystitis among cancer patients compared with the general population cohort was 1.38 (95% confidence interval [95% CI], 1.20-1.58). Overall, the RR for cholecystitis was doubled during the first 6 months after cancer diagnosis (RR = 1.95; 95% CI, 1.50-2.54), after which the RR declined but remained greater than 1 throughout the rest of the follow-up period (RR = 1.23; 95% CI, 1.05-1.45). Cancer patients between the ages of 51 and 70 years had the highest risk increase for cholecystitis compared with other age groups. During the first 6 months after a cancer diagnosis, pancreatic cancers (12 cholecystitis events; RR = 9.44 [95% CI, 5.18-17.18]) and colorectal cancers (10 cholecystitis events; RR = 4.98 [95% CI, 2.65-9.34]) were found to be associated with the greatest cholecystitis risk increase compared with other tumor types. After 6 months, most cancers were associated with a relatively small increased risk, although there was an RR of 4.72 (95% CI, 1.99-11.21) based on 5 cholecystitis events among thyroid cancer patients. CONCLUSIONS The results of the current study indicate that cholecystitis occurs more frequently among cancer patients than in the general population, particularly within the first 6 months after a cancer diagnosis. Clinicians who treat cancer patients should remain vigilant about this type of infection.

Abstract
BACKGROUND The management of gallbladder polyps is controversial. Cholecystectomy has been recommended for gallbladder polyps larger than 10 mm because of the association with gallbladder cancer. Cholecystectomy has also been suggested for gallbladder polyps smaller than 10 mm in patients with biliary type of symptoms. OBJECTIVES The aim of this review is to compare the benefits (relief of symptoms, decreased incidence of gallbladder cancer) and harms (surgical morbidity) of cholecystectomy in patients with gallbladder polyp(s). 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, EMBASE, and Science Citation Index Expanded until July 2008 to identify the randomised trials. SELECTION CRITERIA Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing cholecystectomy and no cholecystectomy were considered for the review. DATA COLLECTION AND ANALYSIS We planned to collect the data on the characteristics, methodological quality, mortality, number of patients in whom symptoms were improved or cured from the one identified trial. We planned to analyse the data using the fixed-effect and the random-effects models using RevMan Analysis. For each outcome we planned to calculate the risk ratio (RR) with 95% confidence intervals based on intention-to-treat analysis. MAIN RESULTS We were unable to identify any randomised clinical trials comparing cholecystectomy versus no cholecystectomy in patients with a gallbladder polyp. AUTHORS' CONCLUSIONS There are no randomised trials comparing cholecystectomy versus no cholecystectomy in patients with gallbladder polyps. Randomised clinical trials with low bias -risk are necessary to address the question of whether cholecystectomy is indicated in gallbladder polyps smaller than10 mm.

Abstract
BACKGROUND The purpose of this study was to determine the incidence and outcome of pancreaticobiliary and duodenal (PB/D) perforations from periampullary endoscopic procedures and to examine whether clinical indexes are predictive of the need for operative management. METHODS A retrospective review compared patients who had operative intervention for PB/D perforation with those managed nonoperatively. RESULTS Thirty-two PB/D perforations occurred in 4,919 procedures (.6%). Twelve (37%) required operation; 20 (63%) were successfully managed nonoperatively. Radiographic imaging was not helpful in predicting the need for operation. A clinical scoring system was predictive of the need for operative management. The length of stay and morbidity rates were higher in the operatively managed patients. CONCLUSIONS Most endoscopic PB/D perforations can be successfully managed without operation and, clinical indices are most predictive in determining the need for surgery. Further prospective evaluation of this scoring system may help guide the need for and timing of operative intervention for PB/D perforations.

Abstract
Endoscopic retrograde pancreatography (ERP) and endoscopic ultrasound (EUS) are superior to cross-sectional imaging procedures for detection of low-grade pancreatitis, but detection of duct alterations is more reliable by middle and high-grade chronic pancreatitis than by low-grade. In addition to assessment of alterations in the pancreatic duct, EUS also allows detection of parenchymatous alterations. Because of the risk of post-ERP pancreatitis, ERP has been mostly eliminated from diagnostic procedures. In contrast, endoscopic retrograde cholangiopancreatography (ERCP) allows an unrivalled access to interventional treatment of inflammatory alterations of the biliopancreatic duct system, by retrograde, non-penetrable papillae even in the rendezvous procedure with EUS-assisted probing of the Ductus Wirsungianus. Despite the technical success of endoscopic procedures, surgical duct decompression has proven to be superior for relief from pancreatitic pain. Biliary drainage is also more likely to be successful on a permanent basis using surgical procedures than by repeat multi-stenting, at least by calcifying pancreatitis. Peroral transgastral transmural therapy of postpancreatitic necroses opens up further options over surgical removal of necroses.

Abstract
The management of most biliopancreatic diseases benefits from endoscopic treatment. Forty years after the first endoscopic cannulation of the ampulla of Vater, the overall effectiveness and safety of endoscopic retrograde cholangiopancreatography (ERCP) can be evaluated using the quality assurance programs that have recently been developed for gastrointestinal endoscopy, including ERCP. Such evaluation does not mean simply reporting therapeutic success and complication rates; rather, it involves a complex analysis of the entire gastrointestinal unit, of the medical practises, and of patient satisfaction. The overall quality of ERCP has been analysed and many quality deficits identified, even in referral centres. Training for such a specialised procedure is difficult and expensive. Competence in ERCP requires as many as 200 ERCP procedures. Quality assurance programs can help to improve the overall quality of endoscopic practise, including training of young endoscopists.

Abstract
BACKGROUND An EUS-guided FNA (EUS-FNA) and a therapeutic ERCP are frequently required for the evaluation of patients who were seen for an obstructing periampullary lesion. OBJECTIVE To determine the feasibility and outcomes of combining an EUS-FNA and a therapeutic ERCP into a single session. DESIGN Retrospective single-center study. SETTING Tertiary-referral cancer center. PATIENTS A total of 114 patients with a suspected malignant obstructing lesion in the pancreatic head. INTERVENTIONS An EUS with or without FNA plus an ERCP. MAIN OUTCOME MEASUREMENTS Duration, diagnostic yield, and complication rate of the combined procedures. RESULTS The mean (SD) total procedure time (EUS, with or without FNA plus ERCP) was 73.6 +/- 30 minutes, with a median of 66 minutes (range 25-148 minutes). In many cases, cytologic diagnosis from FNA became available during an ERCP, which obviated the need for further sampling. EUS-FNA had a sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of 84.6%, 100%, 100%, 62.9%, and 87.8%, respectively. During an ERCP, endoscopic sphincterotomies were performed in 51 patients, and biliary stents were placed in 96 patients. Twelve patients (10.5%) had a complication, with 6 having postprocedural pancreatitis. LIMITATIONS Retrospective single-center experience. CONCLUSIONS Combined EUS-FNA and therapeutic ERCP is technically feasible, with a complication rate no higher than the component procedures, while efficiently providing tissue diagnosis and biliary drainage.

Abstract
The number of gallstone patients is increasing in ageing populations with a high prevalence of metabolic syndrome and obesity. Recently variants of hepatic ATP binding cassette transporters have been identified as genetic susceptibility factors for gallstone disease, pointing to novel means for risk assessment and prevention. Although laparoscopic cholecystectomy is the mainstay of therapy for symptomatic gallbladder stones, the clinical management of gallstone disease is changing rapidly, with an increase in day case surgery and the advent of transluminal endoscopic surgery. Here, we summarize the molecular and genetic mechanisms of gallstone formation as well as the current evidence-based algorithms for diagnosis and therapy of gallbladder and bile duct stones.

Abstract
Endoscopic retrograde pancreatography (ERP) is a sensitive test for the early ductal changes of chronic pancreatitis. More recently, endoscopic ultrasound (EUS) has also been proposed as a sensitive structural test for chronic pancreatitis. Few studies have compared EUS and ERP using an external reference standard. Direct pancreatic function tests (PFT) are an acceptable reference standard for chronic pancreatitis since they detect mild exocrine insufficiency. Our aim was to compare structural abnormalities as revealed by ERP and EUS for the prediction of exocrine insufficiency. Eight-three patients who underwent EUS, ERP, and secretin PFT for the evaluation of pancreatitis were identified from our database. Exocrine insufficiency was defined as a secretin PFT peak bicarbonate concentration <80 mEq/l. Based on the number of abnormal sonographic criteria observed, EUS findings were categorized as normal (<2 criteria), mild (3-5 criteria) or severe (6-9 criteria or calcifications). ERP findings were categorized based on the Cambridge classification. ERP and EUS did not differ significantly in either sensitivity (72% vs 68%, P = 0.52) or specificity (76% vs 79%, P = 0.40). ERP and EUS were similarly associated with exocrine insufficiency both in the presence of minimal (OR 3.4 and 4.9, respectively) and severe structural changes (OR 12 and 24, respectively). We consider EUS to have a diagnostic accuracy for the structural diagnosis of early- and late-stage chronic pancreatitis similar to that of ERP.

Abstract
AIM: To investigate the feasibility of percu-taneous transhepatic cholangiography (PTC) in the diagnosis of adult pancreaticobiliary maljunction (PBM), and to summarize its radiological characteristics.
METHODS: The clinical data of consecutive 257 patients with obstructive jaundice (OJ) receiving the PTC drainage in our hospital from January 1999 to February 2007 were collected. Clinical findings and cholangiopancreatographic results were retrospectively analyzed. Meanwhile the standard for selecting cases and diagnosing PBM was established. A total of 35 cases were selected and both biliary and pancreatic ducts were opacified. The obtained data were statistically analyzed.
RESULTS: PBM was diagnosed in 31 cases, and PTC detection rate was 12.06% (31/257). The length of common duct and the confluence angle of the pancreaticobiliary ducts were 9.87 ± 4.55 mm, which were significantly different from normal values (P < 0.05). The site of duodenal papilla had influences on the length of common duct. The diameters of common bile duct, pancreatic duct and common duct near the confluence were 3.20 ± 1.62 mm, 2.06 ± 0.82 mm, 3.03 ± 1.03 mm, respectively. There was no statistical difference between them and the normal values.
CONCLUSION: PTC is safe, effective and available to diagnose PBM. PTC finding of PBM has its own characteristics to some extent.

Abstract
AIM: To investigate if transnasal endoscopic retrograde cholangiopancreatography (n-ERCP) using an ultrathin forward-viewing scope may overcome the disadvantages of conventional oral ERCP (o-ERCP) related to the large-caliber side-viewing duodenoscope.
METHODS: The study involved 50 patients in whom 25 cases each were assigned to the o-ERCP and n-ERCP groups. We compared the requirements of esophagogastroduodenoscopy (EGD) prior to ERCP, rates and times required for successful cannulation into the pancreatobiliary ducts, incidence of post-procedure hyperamylasemia, cardiovascular parameters during the procedure, the dose of a sedative drug, and successful rates of endoscopic naso-biliary drainage (ENBD).
RESULTS: Screening gastrointestinal observations were easily performed by the forward-viewing scope and thus no prior EGD was required in the n-ERCP group. There was no significant difference in the rates or times for cannulation, or incidence of hyperamylasemia between the groups. However, the cannulation was relatively difficult in n-ERCP when the scope appeared U-shape under fluoroscopy. Increments of blood pressure and the amount of a sedative drug were significantly lower in the n-ERCP group. ENBD was successfully performed succeeding to the n-ERCP in which mouth-to-nose transfer of the drainage tube was not required.
CONCLUSION: n-ERCP is likely a well-tolerable method with less cardiovascular stress and no need of prior EGD or mouth-to-nose transfer of the ENBD tube. However, a deliberate application is needed since its performance is difficult in some cases and is not feasible for some endoscopic treatments such as stenting.
