Abstract
BACKGROUND AND AIMS ERCP is a complex endoscopic procedure in which the center's procedure volume influences outcomes. With the increasing healthcare expenses and limited resources, promoting cost-effective care becomes essential for healthcare provision. This study was a cost-effectiveness analysis to evaluate the hypothesis that high-volume (HV) centers perform ERCP with higher quality at lower costs than low-volume (LV) centers. METHODS A baseline case compared the current distribution of ERCPs among HV and LV centers with a hypothetical scenario in which all ERCPs are performed at HV centers. A cost-effectiveness analysis was constructed, followed by 1- and 2-way sensitivity analyses, and probabilistic sensitivity analysis using Monte Carlo simulations. RESULTS In the baseline case, the incremental cost-effectiveness ratio was -$151,270 per year, due to the hypothetical scenario's lower costs and slightly higher quality-adjusted life years. The model was most sensitive to changes in transportation costs (109.34%), probability of significant adverse events (AEs) after successful ERCP at LV centers (42.12%), utility after ERCP with significant AEs (30.10%), and probability of significant AEs after successful ERCP at HV centers (23.53%); only transportation costs above $3655 changed the study outcome, however. The current ERCP distribution would only be cost-effective if LV centers achieved higher success (≥92.4% vs 89.3%), with much lower significant AEs (≤.5% vs 6.7%). The study's main findings remained unchanged while combining all model parameters in the probabilistic sensitivity analysis. CONCLUSIONS Our findings show that HV centers have high-performance rates at lower costs, raising the need to consider the principle of centralization of ERCPs into HV centers to improve the quality of care.

Abstract
BACKGROUND The management of cholelithiasis and choledocholithiasis combined is controversial. The more frequent approach is a two-stage procedure, with endoscopic sphincterotomy and stone removal from the bile duct followed by laparoscopic cholecystectomy. This study aims to demonstrate how, on the basis of the personal experience, the Rendez-vous technique, that combines the two techniques in a single-stage operation is better than the sequential treatment. METHODS Between June 2017 to December 2019, 40 consecutive patients with cholelithiasis and choledocholithiasis combined were enrolled for the study: 20 were treated with the sequential treatment and 20 with the Rendez-vous method. The preoperative diagnostic work-up was similar in the two group. The endpoints of the study included incidence of endoscopic and surgical complications, rate of hospitalization and cost analysis. RESULTS The study showed no difference in demographic parameters between the two groups, but the success rate of clearance of CBD was significantly smaller for sequential arm, with the need of additional procedures. We found a statistical reduction of postoperative acute pancreatitis, hospital stay and charges in Rendez-vous group, at the expense of a prolonged total operating time. CONCLUSIONS The data of the study confirm the superiority of the Rendez-vous technique because it resolves cholelithiasis associated with choledocholithiasis in a single surgical act, with greater acceptance of the patient who avoids a second invasive surgical act, and with a reduction in complications; moreover, it requires shorter hospitalization, resulting in reduced costs. We propose this option in the management of cases where preoperative ERCP-ES has failed.

Abstract
BACKGROUND AND STUDY AIM Endoscopic retrograde cholangiopancreatography (ERCP) has evolved as the main therapeutic intervention for hepatobiliary disorders. Palliative stenting for inoperable cases is associated with better morbidity and mortality than surgery. This work aimed at assessing the effect of insertion of two plastic stents in inoperable malignant biliary stricture among cirrhotic patients regarding stent patency, quality of life (QOL), and cost. PATIENTS AND METHODS This multicenter study included 72 cirrhotic patients presented for ERCP with an inoperable malignant biliary stricture. All patients underwent ERCP after preoperative optimization with sphincterotomy, balloon dilatation, and insertion of two plastic stents of 10 Fr. Evaluation included stent patency at 6 months, effect on the QOL using EORTC QLQ-C30 (version 3), adverse events, and the cost. RESULTS Patients included 67% of males and had an age range of 48-88 years (mean: 70 years). In all, 92% of stents were patent at 6 months. Significant improvement in serum total bilirubin and all items of QOL questionnaire at 6 months after the procedure was reported. Cholangitis and pancreatitis were reported in 25 and 8% of cases, respectively. The cost of insertion of two plastic stents and the daily cost of the procedure regarding the effect on QOL were low. CONCLUSION Double plastic stenting of the common bile duct seems effective at 6 months of follow-up among cirrhotic patients with inoperable malignant biliary obstruction. Furthermore, it seems also valuable in improving laboratory findings and QOL among those patients with an acceptable cost.

Abstract
BACKGROUND A clinical pathway (CP) is a standardized approach for disease management. However, big data-based evidence is rarely involved in CP for related common bile duct (CBD) stones, let alone outcome comparisons before and after CP implementation.
AIM To investigate the value of CP implementation in patients with CBD stones undergoing endoscopic retrograde cholangiopancreatography (ERCP).
METHODS This retrospective study was conducted at Nanjing Drum Tower Hospital in patients with CBD stones undergoing ERCP from January 2007 to December 2017. The data and outcomes were compared by using univariate and multivariable regression/linear models between the patients who received conventional care (non-pathway group, n = 467) and CP care (pathway group, n = 2196).
RESULTS At baseline, the main differences observed between the two groups were the percentage of patients with multiple stones (P < 0.001) and incidence of cholangitis complication (P < 0.05). The percentage of antibiotic use and complications in the CP group were significantly less than those in the non-pathway group [adjusted odds ratio (OR) = 0.72, 95% confidence interval (CI): 0.55-0.93, P = 0.012, adjusted OR = 0.44, 95%CI: 0.33-0.59, P < 0.001, respectively]. Patients spent lower costs on hospitalization, operation, nursing, medication, and medical consumable materials (P < 0.001 for all), and even experienced shorter length of hospital stay (LOHS) (P < 0.001) after the CP implementation. No significant differences in clinical outcomes, readmission rate, or secondary surgery rate were presented between the patients in the non-pathway and CP groups.
CONCLUSION Implementing a CP for patients with CBD stones is a safe mode to reduce the LOHS, hospital costs, antibiotic use, and complication rate.

Abstract
INTRODUCTION Most patients with malignant biliary obstruction are suited only for palliation by endoscopic drainage with plastic stents (PS) or self-expandable metal stents (SEMS). OBJECTIVE To compare the clinical outcome and costs of biliary stenting with SEMS and PS in patients with malignant biliary strictures. PATIENTS AND METHODS A total of 114 patients with malignant jaundice who underwent 376 endoscopic retrograde biliary drainage (ERBD) were studied. RESULTS ERBD with the placement of PS was performed in 80 patients, with one-step SEMS in 20 patients and two-step SEMS in 14 patients. Significantly fewer ERBD interventions were performed in patients with one-step SEMS than PS or the two-step SEMS technique (2.0±1.12 vs. 3.1±1.7 or 5.7±2.1, respectively, P<0.0001). The median hospitalization duration per procedure was similar for the three groups of patients. The patients' survival time was the longest in the two-step SEMS group in comparison with the one-step SEMS and PS groups (596±270 vs. 276±141 or 208±219 days, P<0.001). Overall median time to recurrent biliary obstruction was 89.3±159 days for PS and 120.6±101 days for SEMS (P=0.01). The total cost of hospitalization with ERBD was higher for two-step SEMS than for one-step SEMS or PS (1448±312, 1152±135 and 977±156&OV0556;, P<0.0001). However, the estimated annual cost of medical care for one-step SEMS was higher than that for the two-step SEMS or PS groups (4618, 4079, and 3995&OV0556;, respectively). CONCLUSION Biliary decompression by SEMS is associated with longer patency and reduced number of auxiliary procedures; however, repeated PS insertions still remain the most cost-effective strategy.

Abstract
Purpose: The diagnostic value and cost-efficiency of MR imaging were compared with US before endoscopic retrograde cholangiopancreatography (ERCP) in patients with clinically suspected biliary tract disease. Material and Methods: In a prospective study of 219 patients, 85 were examined with both MR and US before ERCP. Results: To find the correct diagnosis in the jaundiced patients the sensitivity of US, MR and ERCP was 53%, 93%, and 89%, respectively. In the patients with abdominal upper quadrant pain and normal serum bilirubin, the sensitivity of US, MR and ERCP was 50%, 100% and 70%, respectively. Examination with MR costs four times more than US. Screening with US and supplemental MR in non-diagnostic cases would cost 80% of the total amount compared to screening with MR only. Conclusion: MR had a higher sensitivity than US for diagnosing biliary tract disease and MR was superior to US in visualising stones in the common bile duct and in diagnosing the cause of cholestasis. However, screening with US and supplemental MR in non-diagnostic cases is at present most cost-effective. With increased accessibility and slightly lower costs, MR will probably replace US as screening method in patients with suspected biliary tract disease.

Abstract
AIM: To analyze through meta-analyses the benefits of two types of stents in the inoperable malignant biliary obstruction.
METHODS: A systematic review of randomized clinical trials (RCT) was conducted, with the last update on March 2015, using EMBASE, CINAHL (EBSCO), MEDLINE, LILACS/CENTRAL (BVS), SCOPUS, CAPES (Brazil), and gray literature. Information of the selected studies was extracted in sight of six outcomes: primarily regarding dysfunction, complication and re-intervention rates; and secondarily costs, survival, and patency time. The data about characteristics of trial participants, inclusion and exclusion criteria and types of stents were also extracted. The bias was mainly assessed through the JADAD scale. This meta-analysis was registered in the PROSPERO database by the number CRD42014015078. The analysis of the absolute risk of the outcomes was performed using the software RevMan, by computing risk differences (RD) of dichotomous variables and mean differences (MD) of continuous variables. Data on RD and MD for each primary outcome were calculated using the Mantel-Haenszel test and inconsistency was qualified and reported in χ2 and the Higgins method (I2). Sensitivity analysis was performed when heterogeneity was higher than 50%, a subsequent assay was done and other findings were compiled. Student’s t-test was used for the comparison of weighted arithmetic means regarding secondary outcomes.
RESULTS: Initial searching identified 3660 studies; 3539 were excluded through title, repetition, and/or abstract, while 121 studies were fully assessed and were excluded mainly because they did not compare self-expanding metal stents (SEMS) and plastic stents (PS), leading to thirteen RCT selected, with 13 articles and 1133 subjects meta-analyzed. The mean age was 69.5 years old, that were affected mostly by bile duct (proximal) and pancreatic tumors (distal). The preferred SEMS diameter used was the 10 mm (30 Fr) and the preferred PS diameter used was 10 Fr. In the meta-analysis, SEMS had lower overall stent dysfunction compared to PS (21.6% vs 46.8%, P < 0.00001) and fewer re-interventions (21.6% vs 56.6%, P < 0.00001), with no difference in complications (13.7% vs 15.9%, P = 0.16). In the secondary analysis, the mean survival rate was higher in the SEMS group (182 d vs 150 d, P < 0.0001), with a higher patency period (250 d vs 124 d, P < 0.0001) and a lower cost per patient (4193.98 vs 4728.65 Euros, P < 0.0985).
CONCLUSION: SEMS are associated with lower stent dysfunction, lower re-intervention rates, better survival, and higher patency time. Complications and costs showed no difference.

Abstract
BACKGROUND The optimal management of patients with suspected biliary obstruction remains unclear, and includes the possible performance of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). OBJECTIVES To complete a cost analysis based on a medical effectiveness randomized trial comparing an ERCP-first approach with an MRCP-first approach in patients with suspected bile duct obstruction. METHODS The management strategies were based on a medical effectiveness trial of 257 patients over a 12-month follow-up period. Direct and indirect costs were included, adopting a societal perspective. The cost values are expressed in 2012 Canadian dollars. RESULTS Total per-patient direct costs were Can$3547 for ERCP-first patients and Can$4013 for MRCP-first patients. Corresponding indirect costs were Can$732 and Can$694, respectively. Causes for differences in direct costs included a more frequent second procedure and a greater mean number of hospital days over the year in patients of the MRCP-first group. In contrast, it is the ERCP-first patients whose indirect costs were greater, principally due to more time away from activities of daily living. Choosing an ERCP-first strategy rather than an MRCP-first strategy saved on average Can$428 per patient over the 12-month follow-up duration; however, there existed a large amount of overlap when varying total cost estimates across a sensitivity analysis range based on observed resources utilization. CONCLUSIONS This cost analysis suggests only a small difference in total costs, favoring the ERCP-first group, and is principally attributable to procedures and hospitalizations with little impact from indirect cost measurements.

Abstract
Up to 18% of patients submitted to cholecystectomy had concomitant common bile duct stones. To avoid serious complications, these stones should be removed. There is no consensus about the ideal management strategy for such patients. Traditionally, open surgery was offered but with the advent of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) minimally invasive approach had nearly replaced laparotomy because of its well-known advantages. Minimally invasive approach could be done in either two-session (preoperative ERCP followed by LC or LC followed by postoperative ERCP) or single-session (laparoscopic common bile duct exploration or LC with intraoperative ERCP). Most recent studies have found that both options are equivalent regarding safety and efficacy but the single-session approach is associated with shorter hospital stay, fewer procedures per patient, and less cost. Consequently, single-session option should be offered to patients with cholecysto-choledocholithiaisis provided that local resources and expertise do exist. However, the management strategy should be tailored according to many variables, such as available resources, experience, patient characteristics, clinical presentations, and surgical pathology.

Abstract
Compared to standard endoscopy, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are often lengthier and more complex, thus requiring higher doses of sedatives for patient comfort and compliance. The aim of this review is to provide the reader with information regarding the use, safety profile, and merits of propofol for sedation in advanced endoscopic procedures like ERCP and EUS, based on the current literature.

Abstract
BACKGROUND/AIMS This study aims to compare the clinical outcomes and costs between endoscopic biliary stenting (EBS) and percutaneous transhepatic biliary stenting (PTBS). METHODOLOGY We randomly assigned 112 patients with unresectable malignant biliary obstruction 2006 and 2011 to receive EBS or PTBS with self-expandable metal stent (SEMS) as palliative treatment. PTBS was successfully performed in 55 patients who formed the PTBS group (failed in 2 patients). EBS was successfully performed in 52 patients who formed the EBS group (failed in 3 patients). The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. RESULTS Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the BBS group (P < 0.05). There was no significant difference in effectiveness of biliary drainage (P = 0.9357) or survival time between two groups (P = 0.6733). Early complications occurred in PTBS group was significantly lower than in EBS group (3/55 vs 11/52, P = 0.0343). Late complications in the EBS group did not differ significantly from PTBS group (7/55 vs 9/52, P = 0.6922). The survival curves in the two groups showed no significant difference (P = 0.5294). Conclusions: 3.

Abstract
BACKGROUND The aim of this study was to determine the financial costs to institution on patients waiting for gall bladder disease surgery and suggest measures to reduce them. METHODS This multi-centre prospective descriptive survey was performed on all patients who underwent an elective cholecystectomy by three consultants at secondary care hospitals in Pakistan between Jan 2010 to Jan 2012. Data was collected on demographics, the duration of mean waiting time, specific indications and nature of disease for including the patients in the waiting list, details of emergency re-admissions while awaiting surgery, investigations done, treatment given and expenditures incurred on them during these episodes. RESULTS A total of 185 patients underwent elective open cholecystectomy. The indications for listing the patients for surgery were biliary colic in 128 patients (69%), acute cholecystitis in 43 patients (23%), obstructive jaundice in 8 patients (4.5%) and acute pancreatitis in 6 patients (3.2%). 146 (78.9%) and 39 (21.1%) of patients were listed as outdoor electives and indoor emergencies respectively. Of the 185 patients, 54 patients (29.2%) were re-admitted. Financial costs in Pakistani rupees per episode of readmission were 23050 per episode in total and total money spent on all readmissions was Rs. 17,05,700/-. CONCLUSION Financial costs on health care institutions due to readmissions in patients waiting for gall bladder disease surgery are high. Identifying patients at risk for these readmissions and offering them early laparoscopic cholecystectomy is very important.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP) are often required in patients with pancreaticobiliary disorders. AIMS To assess the clinical impact and costs savings of a single session EUS-ERCP. METHODS Patient and intervention data from April 2009 to March 2012 were prospectively recruited and retrospectively analyzed from a database at a tertiary hospital. Indications, diagnostic yield, procedure details, complications and costs were evaluated. RESULTS Fifty-five scheduled combined procedures were done in 53 patients. The accuracy of EUS-fine needle aspiration for malignancy was 90%. The main clinical indication was a malignant obstructing lesion (66%). The ERCP cannulation was successful in 67%, and in 11/15 failed ERCP (73%), drainage was completed thanks to an EUS-guided biliary drainage: 6 transmurals, 5 rendezvous. Eight patients (14%) had related complications: bacteremia (n = 3), pancreatitis (n = 2), bleeding (n = 2) and perforation (n = 1). The mean duration was 65 ± 22.2 min. The mean estimated cost for a single session was €3437, and €4095 for two separate sessions. The estimated cost savings using a single-session strategy was €658 per patient, representing a total savings of €36,189. CONCLUSION Combined EUS and ERCP is safe, technically feasible and cost beneficial. Furthermore, in failed ERCP cases, the endoscopic biliary drainage can be completed with EUS-guided biliary access in the same procedure.

Abstract
BACKGROUND Data on balloon enteroscopy-assisted ERCP (BEA-ERCP) versus laparoscopy-assisted ERCP (LA-ERCP) in post-Roux-en-Y gastric bypass (RYGB) patients are lacking. OBJECTIVES To compare BEA-ERCP with LA-ERCP in post-RYGB patients and to identify factors that predict therapeutic success with BEA-ERCP. DESIGN Retrospective chart review. SETTING A single North American tertiary referral center. PATIENTS The review included 56 bariatric post-RYGB patients who underwent ERCP. INTERVENTIONS BEA-ERCP or LA-ERCP. MAIN OUTCOME MEASUREMENTS Cannulation rate, therapeutic success, hospital stay, complications, procedure duration, endoscopist time, and cost. RESULTS A total of 32 patients underwent BEA-ERCP, and 24 underwent LA-ERCP. LA-ERCP was superior to BEA-ERCP in papilla identification (100% vs 72%, P = .005), cannulation rate (100% vs 59%, P < .001), and therapeutic success (100% vs 59%, P < .001). The total procedure time was shorter (P < .001) and endoscopist time was longer (P = .006) for BEA-ERCP. There was no difference in postprocedure hospital stay (P = .127) or complication rate (P = .392) between the 2 groups. In the BEA-ERCP group, in patients having a Roux limb + biliopancreatic (from ligament of Treitz to jejunojejunal anastomosis), a limb length less than 150 cm was associated with therapeutic success. Starting with BEA-ERCP and continuing with LA-ERCP after a failed BEA-ERCP saved $1015 compared with starting with LA-ERCP. LIMITATIONS Single center, retrospective study. CONCLUSIONS In centers with expertise in deep enteroscopy and ERCP, post-RYGB patients with a Roux + ligament of Treitz to jejunojejunal anastomosis limb length less than 150 cm should first be offered deep enteroscopy-assisted ERCP. In patients with Roux + ligament of Treitz to jejunojejunal anastomosis (LTJJ) limb length 150 cm or longer, LA-ERCP should be the preferred approach because of the lack of need for a second procedure, equivalent morbidity and hospital stay, decreased endoscopist time, and decreased cost.

Abstract
BACKGROUND In countries where ERCP costs are low relative to those of metal stents (eg, Korea), initial endoscopic retrograde biliary drainage (ERBD) with a plastic stent is thought to be more economical. OBJECTIVE We conducted this study to compare metal and plastic stent-based ERBD in efficacy, complications, and total cost of biliary drainage. DESIGN Retrospective study. SETTING Tertiary referral center. PATIENTS A total of 112 patients who had not undergone previous biliary drainage procedures and who underwent ERBD for unresectable malignant biliary obstruction. INTERVENTIONS Endoscopic sphincterotomy was performed, and covered or uncovered Wallstents were used in 56 patients and plastic stents in 56 patients. RESULTS Stent occlusion occurred in 31 patients after a mean of 278 days in the metal stent group and in 39 patients after a mean of 133 days in the plastic stent group (P = .0004). The incidence of and length of hospitalization for cholangitis were significantly lower in the metal stent group. There was no difference in the total number of drainage procedures between the 2 groups. There was no statistical difference in the mean cost of the relief of jaundice between the 2 groups ($1488.77 in the metal stent group vs $1319.26 in the plastic stent group, P = .422). LIMITATIONS Nonrandomized, retrospective study. CONCLUSION Even in countries where ERCP costs are lower than those of metal stents, ERBD with metal biliary stents as the first-line treatment may offer better palliation without a significant increased cost in patients with unresectable malignant biliary obstruction.

Abstract
BACKGROUND In the era of cost-conscious healthcare, hospitals are focusing on costs. Analysis of hospital costs per cost category may provide indications for potential cost-saving measures in the management of common bile duct stones (CBDS) with gallbladder in situ. METHODS Between October 2005 and September 2006, 53 consecutive patients suffering from CBDS underwent either a one-stage procedure [laparoscopic common bile duct exploration (LCBDE) with stone clearance and cholecystectomy (LCCE)] or a two-stage procedure [endoscopic retrograde cholangiopancreatography with sphincterotomy and stone clearance (ERCP/ERS) followed by LCCE]. Costs were defined in different cost categories for each activity centre and were linked to the individual patient via the "bill of activities". Only patients (n = 38) with an uneventful post-procedural course and with available cost data were considered for cost analysis. Total length of hospital stay (LOS) was 2 (0-6) days after one-stage and 8 (3-18) days after two-stage procedure (p < 0.0001). RESULTS Costs per patient were significantly (p < 0.0001) less after one-stage versus two-stage management, i.e. total hospital costs (euro2,636 versus euro4,608), hospitalisation costs (euro701 versus euro2,190), consumables/pharmacy (euro645 versus euro1,476) and para-medical personnel (euro1,035 versus euro1,860; p = 0.0002). Operation room (OR) costs were comparable for one-stage and two-stage management (euro1,278 versus euro1,232; p = 0.280). Total hospital costs during ERCP were euro2,648 (euro729-4,544), during LCCE without LCBDE were euro2,101 (euro1,033-4,269), and during LCCE with LCBDE were euro2,636 (euro1,176-4,235). CONCLUSION In the management of patients with CBDS and gallbladder in situ a one-stage procedure is associated with significantly less costs as compared with a two-stage procedure. From the economical point of view these patients should preferably be treated via a one-stage procedure as long as safety and efficacy of this approach are provided.

Abstract
BACKGROUND Endosonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are highly accurate techniques for evaluating common bile duct stones. AIM To compare the clinical impact and costs of EUS- and ERCP-based strategies for evaluating patients with suspected common bile duct stones but normal transabdominal imaging. METHODS The costs of EUS- vs. ERCP-based strategies were compared in patients with suspected acute biliary obstruction from common bile duct stones but normal transabdominal imaging. RESULTS Over a 15-month period, 110 patients were recruited. EUS detected a common bile duct lesion in 73% (common bile duct stones: 68%; pancreatic cancer: 2%; ampulla tumour: 2%; cholangiocarcinoma: 1%). The sensitivity, specificity, positive predictive value and negative predictive value of EUS were 98%, 100%, 100% and 93%, respectively. EUS prevented 30% unnecessary ERCP. The mean difference in cost per patient between EUS- and ERCP-based strategies was US$166. When stratified according to clinical indications, an EUS-based strategy was costlier only in suspected biliary sepsis. Costs were similar when the indications were cholestatic jaundice, acute pancreatitis and cholestasis. CONCLUSION EUS prior to biliary interventions in patients with suspected common bile duct stones prevented unnecessary ERCP. It allowed a definitive diagnosis to be made prior to more invasive procedures.

Abstract
The ideal management of presumed choledocholithiasis is controversial. We hypothesized that patients admitted with presumed choledocholithiasis would be better served financially to undergo laparoscopic cholecystectomy (LC) with possible intraoperative intervention versus preoperative endoscopic retrograde cholangiopancreatography followed by LC. A chart review was performed from September 1, 2000 to August 31, 2003. One hundred seventy-one consecutive patients identified with presumed choledocholithiasis were reviewed. Six patients were excluded because of missing charge data. Professional and technical fees from the total hospital charges were used for comparison. Three groups of patients were compared for charge analysis. Group 1 underwent LC with laparoscopic common bile duct exploration. Group 2 underwent LC with preoperative or postoperative endoscopic retrograde cholangiopancreatography. Group 3 was a control group of LC only. Student's t test was used for statistical analysis with a P value of <0.05 defined as statistically significant. P values reflect comparisons with Group 1. Group 1 charges were $13,026, Group 2 charges were $15,303, and Group 3 charges were $9,122. For suspected choledocholithiasis, LC with intraoperative intervention is the most economically advantageous approach.

Abstract
BACKGROUND In chronic pancreatitis, obstruction of the main pancreatic duct (MPD) may contribute to the pathogenesis of pain. Pilot studies suggest that extracorporeal shock wave lithotripsy (ESWL) alone relieves pain in calcified chronic pancreatitis. AIM To compare ESWL alone with ESWL and endoscopic drainage of the MPD for treatment of pain in chronic pancreatitis. SUBJECTS Patients with uncomplicated painful chronic pancreatitis and calcifications obstructing the MPD. METHODS 55 patients were randomised to ESWL alone (n = 26) or ESWL combined with endoscopy (n = 29). RESULTS 2 years after trial intervention, 10 (38%) and 13 (45%) patients of the ESWL alone and ESWL combined with endoscopy group, respectively, had presented pain relapse (primary outcome) (OR 0.77; 95% CI 0.23 to 2.57). In both groups, a similar decrease was seen after treatment in the MPD diameter (mean decrease 1.7 mm; 95% CI 0.9 to 2.6; p<0.001), and in the number of pain episodes/year (mean decrease, 3.7; 95% CI 2.6 to 4.9; p<0.001). Treatment costs per patient were three times higher in the ESWL combined with endoscopy group compared with the ESWL alone group (p = 0.001). The median delay between the onset of chronic pancreatitis and persistent pain relief for both groups was 1.1 year (95% CI 0.7 to 1.6), as compared with 4 years (95% CI 3 to 4) for the natural history of chronic pancreatitis in a reference cohort (p<0.001). CONCLUSIONS ESWL is a safe and effective preferred treatment for selected patients with painful calcified chronic pancreatitis. Combining systematic endoscopy with ESWL adds to the cost of patient care, without improving the outcome of pancreatic pain.

Abstract
BACKGROUND AND STUDY AIMS The optimal approach for diagnosing sclerosing cholangitis remains unclear in the face of competing imaging technologies. We aimed to determine the most cost-effective strategy. PATIENTS AND METHODS A decision model compared three approaches in the work-up of patients with suspected sclerosing cholangitis; all included an initial test, with, if unsuccessful, performance of a second cholangiographic method. They were magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP), termed "MRCP_ERCP", ERCP and MRCP ("ERCP_MRCP"), or ERCP and a repeat ERCP ("ERCP_ERCP"). The implications of true and false positive and negative results with regard to costs and procedural complications were considered, including that of a liver biopsy, if indicated as a result of a negative work-up in the face of persistent clinical suspicion. The unit of effectiveness adopted was that of a correct diagnosis. Probability assumptions were derived from published literature, while cost estimates were derived from time-motion microanalyses or a national database, and expressed in Canadian dollars at 2004 values. Sensitivity analyses, including clinically relevant threshold analyses, were carried out. RESULTS The average cost-effectiveness ratios were $414 for MRCP_ERCP, $1101 for ERCP_MRCP and $1123 for ERCP_ERCP, per correct diagnosis. The ERCP_MRCP strategy was dominated (more expensive and less effective) by MRCP_ERCP, while ERCP_ERCP was more effective and more costly than MRCP_ERCP, at $289,292 per additional correct diagnosis. Sensitivity and threshold analyses confirmed the robustness of these findings. CONCLUSIONS Based on the model assumptions, a strategy of initial MRCP, followed, if negative, by ERCP is currently the most cost-effective approach to the work-up of patients with suspected sclerosing cholangitis.

Abstract
HYPOTHESIS Endoscopic retrograde cholangiopancreatography (ERCP) is more cost-effective for managing incidental choledocholithiasis (CDL) after laparoscopic cholecystectomy and intraoperative cholangiogram (LC/IOC) than laparoscopic common bile duct exploration (LCBDE). DESIGN A cost-effectiveness analysis was performed to compare ERCP with LCBDE. Sensitivity analyses were performed to determine the key contributors to cost-effectiveness between the 2 treatment options. SETTING Costs were approached from the institutional perspective considering a typical patient undergoing LC/IOC at a large referral center. PATIENTS The base case patient evaluated was a woman 18 years of age or older with symptomatic cholelithiasis and incidental CDL discovered at the time of LC/IOC. INTERVENTIONS Endoscopic retrograde cholangiopancreatography with drainage procedure performed after LC/IOC or LCBDE during LC/IOC. MAIN OUTCOME MEASURES Costs, quality-adjusted life years gained, mean cost-effectiveness ratios, and incremental cost-effectiveness ratios. RESULTS In the base case analysis, ERCP was the optimal treatment choice with a cost of $24 300 for 0.9 quality-adjusted life years gained compared with $28 400 and 0.88 quality-adjusted life years for LCBDE. Endoscopic retrograde cholangiopancreatography remained the optimal strategy for CDL in multiway probabilistic sensitivity analysis. If LCBDE were performed and the cost of a potential operative case lost was $3100 or less and the cost of ERCP hospitalization was $18 000 or more, then LCBDE became the preferred treatment for CDL. CONCLUSIONS Endoscopic retrograde cholangiopancreatography was both less costly and more effective than LCBDE. Factors important to choosing the best strategy for CDL management included the cost of a potential case lost due to LCBDE performance and the cost of ERCP hospitalization.

Abstract
BACKGROUND AND STUDY AIMS Several drugs have been used for the prevention of post-ERCP pancreatitis with conflicting results and no data referring to the routine use of a pharmacological prophylaxis have been published up to now. Aim of the study was to evaluate the frequency of post-ERCP pancreatitis and costs in a series of consecutive patients who have undergone ERCP procedures before and after the introduction of a routine prophylaxis with gabexate in all cases. PATIENTS AND METHODS Data from 1312 patients who underwent ERCP procedures without gabexate prophylaxis and from 1149 consecutive patients with 1g i.v. gabexate, were retrospectively evaluated during a 6-year period. Patients were also subdivided in standard- and high-risk subjects, on the basis of patient- and technique-related risk factors: 984 subjects (39.9%) had one or more conditions that placed them at high risk for post-ERCP pancreatitis. RESULTS Post-ERCP pancreatitis was reported in 76 out of 2461 patients (3.1%). The frequency of pancreatitis appeared significantly reduced in the gabexate period in comparison with before gabexate in overall cases (2.2% versus 3.9%; p=0.019); however, the reduction was significant only for high-risk patients (3.8% versus 7.3%; p=0.001). Severe hyperamylasaemia at 4-6h and 24h after the procedure was also significantly reduced only in high-risk patients (p=0.001). Routine prophylaxis with gabexate appeared cost-effective in high-risk patients. CONCLUSIONS Routine gabexate prophylaxis was associated with a significant reduction of post-ERCP pancreatitis rate, severe hyperamylasaemia and hospitalisation-related costs only in high-risk patients. However, gabexate appeared unable to reduce the incidence of severe pancreatitis.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is considered the gold standard for imaging of the biliary tract but is associated with complications. Less invasive imaging techniques, such as magnetic resonance cholangiopancreatography (MRCP), have a much lower complication rate. The accuracy of MRCP is comparable to that of ERCP, and MRCP may be more effective and cost-effective, particularly in cases for which the suspected prevalence of disease is low and further intervention can be avoided. A model was constructed to compare the effectiveness and cost-effectiveness of MRCP and ERCP in patients with a previous history of cholecystectomy, presenting with abdominal pain and/or abnormal liver function tests. METHODS Diagnostic accuracy estimates came from a systematic review of MRCP. A decision analytic model was constructed to represent the diagnostic and treatment pathway of this patient group. The model compared the following two diagnostic strategies: (i) MRCP followed with ERCP if positive, and then management based on ERCP; and (ii) ERCP only. Deterministic and probabilistic analyses were used to assess the likelihood of MRCP being cost-effective. Sensitivity analyses examined the impact of prior probabilities of common bile duct stones (CBDS) and test performance characteristics. The outcomes considered were costs, quality-adjusted life years (QALYs), and cost per additional QALY. RESULTS The deterministic analysis indicated that MRCP was dominant over ERCP. At prior probabilities of CBDS, less than 60 percent MRCP was the less costly initial diagnostic test; above this threshold, ERCP was less costly. Similarly, at probabilities of CBDS less than 68 percent, MRCP was also the more effective strategy (generated more QALYs). Above this threshold, ERCP became the more effective strategy. Probabilistic sensitivity analyses indicated that, in this patient group for which there is a low to moderate probability of CBDS, there was a 59 percent likelihood that MRCP was cost-saving, an 83 percent chance that MRCP was more effective with a higher quality adjusted survival, and an 83 percent chance that MRCP had a cost-effectiveness ratio more favorable than dollars 50,000 per QALY gained. CONCLUSIONS Costs and cost-effectiveness are dependent upon the prior probability of CBDS. However, probabilistic analysis indicated that, with a high degree of certainty, MRCP was the more effective and cost-effective initial test in postcholecystectomy patients with a low to moderate probability of CBDS.

Abstract
BACKGROUND Two treatment options exist for choledocholithiasis (CDL): endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct exploration (CBDE). Resource utilization measured by total in-hospital charges (THC) and length of stay (LOS) was compared using the propensity score (PS). In this study, PS was the probability that a patient received CBDE based on comorbidities and demographics. The power of this method lies in balancing groups on variables by PS, resulting in 90% bias reduction and improved inferential validity compared to traditional analytic techniques. METHODS Laparoscopic cholecystectomy (LC) patients with CDL who had ERCP or CBDE were identified in the 2002 U.S. Nationwide Inpatient Sample. Patients were ordered into five PS balanced strata. Mean THC, LOS, and estimated costs were compared. A linear regression model was used to estimate the contribution that LOS had on estimated costs. Monetary values were adjusted to 2004 dollars. RESULTS A total of 40,982 patients underwent LC with CDL in 2002; 27,739 had either ERCP (93%) or CBDE (7%). Mean age was 52.7 +/- 0.4 years, with 74% women. Mean THC were less for CBDE (25,200 dollars +/- 1,800 dollars) than for ERCP (29,900 dollars +/- 800 dollars, p < 0.05). Mean LOS was less for CBDE (4.9 +/- 0.2 days) than for ERCP (5.6 +/- 0.1 days, p < 0.05). PS adjusted analysis revealed an estimated overall cost savings of 4,500 dollars +/- 1,600 dollars and reduced LOS (0.6 +/- 0.2 days) per hospitalization for CBDE. Mean THC, LOS, and estimated costs across PS score balanced strata were generally higher in the ERCP group compared to the CBDE group. LOS contributed 53% to increased THC and 62% of estimated costs. A higher cumulative incidence of complications was evident with CBDE (0.5-4.6%) compared to ERCP (0.3-3.6%). CONCLUSIONS Based on this PS analysis, CBDE incurs less THC, reduces LOS, and has less estimated costs for CDL compared to ERCP. Furthermore, CBDE appears to be dramatically underutilized.

Abstract
BACKGROUND ERCP is used selectively in patients with acute biliary pancreatitis (ABP). In patients with ABP, ERCP often is difficult and has the potential to cause further damage. In addition, the prevalence of residual choledocholithiasis in ABP is low (<30%). EUS and MRCP accurately diagnose choledocholithiasis, but the performance of MRCP may be inferior in ABP. EUS, with ERCP when a stone is seen, has been shown to be feasible. This study assessed the relative costs and outcomes of EUS and MRCP in patients with ABP compared with standard care involving selective ERCP. METHODS A decision tree was constructed, modeling standard care for nonsevere ABP (selective ERCP) and severe ABP (ERCP with sphincterotomy and balloon sweep). The other arms included either EUS or MRCP first, with the conversion to or the addition of ERCP when a bile-duct stone was seen. Probabilities and accuracy of EUS and MRCP were taken from published data. Costs were locally quantified in Canadian dollars (CDN), including nursing/technical/professional personnel, equipment maintenance, and disposable equipment. The robustness of assumptions was tested by sensitivity analyses. RESULTS Overall, EUS in all patients with ABP was marginally dominant compared with standard care with selective ERCP ($58 CDN per patient less expensive; 0.9% fewer cases of pancreatitis [ERCP-related or recurrent]). In the severe ABP subgroup, EUS was more clearly dominant ($742 CDN per patient less expensive; 3% fewer cases of pancreatitis), and the nonsevere subgroup had an incremental cost-effectiveness ratio of $17,000 per case of pancreatitis avoided. MRCP was more expensive than EUS in both subgroups. CONCLUSIONS EUS is dominant in severe ABP. In nonsevere ABP, it is slightly more costly but is associated with fewer ERCPs and ERCP-related complications. A randomized trial would help to quantify the benefits of avoiding ERCP in these patients.

Abstract
BACKGROUND Several modalities currently exist for tissue confirmation of suspected pancreatic cancer prior to therapy. Since there is a paucity of cost-minimization studies comparing these different biopsy modalities, we analyzed costs and examined effectiveness of four alternative strategies for diagnosing pancreatic cancer. METHODS A decision analysis model of patients with suspected pancreatic cancer was constructed. We analyzed costs, failure rate, testing characteristics, and complication rates of four commonly employed diagnostic modalities: 1) computerized tomography or ultrasound-guided fine-needle aspiration (CT/US-FNA), 2) endoscopic retrograde cholangiopancreatography with brushings (ERCP-B), 3) Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA), and 4) laparoscopic surgical biopsy. If the first attempt with a particular modality failed, a different modality was employed to identify the most preferable secondary biopsy strategy. RESULTS This analysis identifies EUS-FNA as the preferred initial modality for the diagnosis of pancreatic cancer. Resultant expected costs and strategies in decreasing optimality include: 1) EUS-FNA (1,405 dollars), 2) ERCP-B (1,432 dollars), 3) CT/US-FNA (3,682 dollars), and 4) surgery (17,711 dollars). If a patient presents with obstructive jaundice, decision analysis modeling resulted in a total expected costs of 1,970 dollars if ERCP-B is successful at the time of biliary stent placement. Additional analyses to identify the preferred follow-up modality after a failed alternative method showed that EUS-FNA is the preferred secondary modality if any of the other three modalities failed first, in both the setting of and absence of obstructive jaundice. One- and two-way sensitivity analysis of the variables shows unchanged results over an acceptable range. CONCLUSIONS This cost-minimization study illustrates that EUS-FNA is the best initial and the preferred secondary alternative method for the diagnosis of suspected pancreatic cancer. In addition to local expertise and availability, costs and diagnostic yield should be considered when choosing an optimal diagnostic strategy.

Abstract
BACKGROUND The choice between reusable and single-use devices for ERCP depends on various medical and economic criteria. This study evaluated the reliability and the safety (risk of cross-contamination) of reusable devices. A cost analysis of the use of reusable devices also was conducted. METHODS All patients referred for ERCP that required use of a sphincterotome or a retrieval basket were eligible for inclusion in a clinical study of 4 different devices (3 types of sphincterotome, 1 type of retrieval basket). All devices were steam sterilized. Before each use, each device was subjected to bacteriologic and virologic tests (hepatitis C virus, hepatitis B virus markers). Devices were examined before and after each procedure. The numbers of safe and efficient procedures that could be performed with each device were assessed. Three strategies were compared in a cost analysis: internal reprocessing (strategy 1), external reprocessing (strategy 2), and single-use (strategy 3). Inputs used were the results of the clinical study, hospital data for 1 year of endoscopic activity, and market prices. RESULTS A total of 342 patients underwent the following procedures: sphincterotomy (248 patients), stent insertion (59 patients), use of basket without sphincterotomy (14 patients), and diagnostic ERCP/unsuccessful cannulation (21 patients). At the time of ERCP, 36 patients had viral or bacterial infection. Fifty instruments were used (20 single-lumen sphincterotomes, 10 double lumen sphincterotomes, 20 retrieval baskets). Overall, the median number of efficient uses per device was 10. The median number of efficient uses by each type of device was the following: single-lumen sphincterotome, 12; double-lumen sphincterotome, 8; and, retrieval baskets, 10. All virologic and bacteriologic tests for all instruments were negative. The cost-optimization analysis found that strategy 1 is cost effective (euro37,283/y) compared with strategy 2 (euro40,101/y) and especially with Strategy 3 (euro115,210/y). CONCLUSIONS Reuse of the sphincterotomes and baskets evaluated in this study during ERCP is safe in terms of infectious hazards. Because they endure numerous uses, reusable instruments are cost effective, especially when compared with single-use accessories.

Abstract
Investigations examining the use of magnetic resonance cholangiography (MRC) for the diagnosis of primary sclerosing cholangitis (PSC) have described comparable accuracy when compared to endoscopic retrograde cholangiopancreatography (ERCP). The effectiveness of MRC based on overall cost, however, remains unknown. Our aim was to determine the average cost per correct diagnosis using MRC or ERCP as the initial testing strategy for the diagnosis of PSC. A decision analysis model was constructed employing diagnostic test parameters prospectively determined among 73 patients with clinically suspected biliary disease. ERCP was performed within 24 hours after MRC. Cost data were derived from average Medicare reimbursement fee schedules. The prevalence of PSC in the study cohort was 32%. The sensitivity and specificity of MRC for the diagnosis of PSC were 82% and 98%, respectively. The average cost per correct diagnosis of PSC was 724.00 US dollars for initial MRC (including the cost of ERCP following a negative MRC examination) versus 793.17 US dollars for initial ERCP. In the absence of biliary obstruction, the average cost per correct diagnosis of PSC was 549.64 US dollars with MRC versus 623.25 US dollars or ERCP. The average cost of managing post-ERCP-related complications among patients with PSC was 2902.20 US dollars (range, 1915.40-5031.54 US dollars). For ERCP to be the optimal initial test strategy, a prevalence rate of PSC greater than 45%, MRC specificity less than 85%, or reduction in the average cost per diagnosis to 538.30 US dollars would be required. In conclusion, MRC has comparable accuracy to ERCP and results in cost savings when used as the initial test strategy for diagnosing PSC.

Abstract
BACKGROUND It is not known whether initial endoscopic ultrasonography (EUS) or magnetic resonance cholangiopancreatography (MRCP) is more cost effective than endoscopic retrograde cholangiopancreatography (ERCP). METHODS A cost-effectiveness analysis of EUS, MRCP and ERCP was performed on 163 patients. The effectiveness of an investigation was defined as the percentage of patients with no need for further evaluation after the investigation in question had been performed. Costs were assumed from the budget-holder's point of view. RESULTS MRCP, EUS and ERCP had a total accuracy of 0.91, 0.93 and 0.92, respectively. Eighty-four (52%) patients needed endoscopic therapy in combination with ERCP, giving an effectiveness of MRCP, EUS, and ERCP of 0.44, 0.45 and 0.92, respectively. The cost-effectiveness of MRCP, EUS, and ERCP was 6622, 7353 and 4246 Danish Kroner (DKK) per fully investigated and treated patient (1 DKK=0.14 EUR). CONCLUSION Within a patient population with a probability of therapeutic ERCP in 50% of the patients, ERCP was the most cost-effective strategy.

Abstract
OBJECTIVES To compare the clinical and cost-effectiveness of magnetic resonance cholangiopancreatography (MRCP) with diagnostic endoscopic retrograde cholangiopancreatography (ERCP) for the investigation of biliary obstruction. DATA SOURCES Electronic bibliographic databases, the reference lists of relevant articles and various health services research-related resources. REVIEW METHODS The data sources were searched and selected studies were assessed using quality criteria. In total, 28 prospective diagnostic studies were identified reporting several suspected conditions plus one of patient satisfaction. Analyses were then performed to establish sensitivities, specificities, likelihood ratios and confidence intervals. The relative cost-effectiveness of adopting MRCP scanning in the investigation of the biliary tree was undertaken using a probabilistic economic model. RESULTS The median sensitivity for choledocholithiasis (13 studies) was 93% and the median specificity 94%. The median likelihood ratio for a positive value was 15.75 and for a negative value 0.08. Reported sensitivities for malignancy were somewhat lower, ranging from 81 to 86%, and specificities ranged from 92 to 100%. There was some evidence that MRCP is an accurate diagnostic test in comparison to ERCP, although the quality of studies was moderate. Claustrophobia prevented at least some patients from having MRCP in ten of the 28 studies. The other 18 studies did not mention claustrophobia. The probability of avoiding unnecessary diagnostic ERCP is estimated at 30%. These patients could avoid the unnecessary risk of complications and death associated with diagnostic ERCP, and substantial cost saving would be gained. The overall expected cost saving associated with MRCP is GBP149; the overall expected gain in quality-adjusted life-year is estimated at 0.011. CONCLUSIONS There is some evidence that MRCP is an accurate investigation compared with diagnostic ERCP, although the values for malignancy compared with choledocholithiasis were somewhat lower. The quality of studies was moderate. The limited evidence on patient satisfaction showed that patients preferred MRCP to diagnostic ERCP. The estimated clinical and economic impacts of diagnostic MRCP versus diagnostic ERCP are very favourable. The baseline estimate is that MRCP may both reduce cost and result in improved quality of life outcomes compared with diagnostic ERCP. Further research is suggested to compare MRCP and diagnostic ERCP with final diagnosis and also with the full range of target conditions; to examine patient satisfaction and ways of reducing problems with claustrophobia; to look at protocols to help identify who could most benefit from MRCP or ERCP; to assess the relative need and urgency of patient access to magnetic resonance imaging services, and also to determine how demand would affect availability and potential cost savings.

Abstract
The purpose of this study was to compare ERCP and MRCP in terms of invasiveness and cost. A questionnaire regarding patient satisfaction was distributed to 23 ERCP patients and 63 MRCP patients. The practical cost of each examination and total yearly cost for 2002, including medication costs for post-ERCP pancreatitis, were calculated. On a trial basis, the total yearly cost for 2002 was also calculated as a percentage of the cost in 1996. Results of the questionnaire showed that patients tended to favor MRCP over ERCP. In our hospital, the practical costs of MRCP and ERCP were 2063 points and 3964 points, respectively. Medication costs for pancreatitis corresponded to about 3% of the total yearly cost for ERCP. The total yearly costs for both examinations and the medication costs for pancreatitis were about 1,360,000 points. The result of trial calculation with the examination percentage of 1996 was about 1,950,000 points. The results of our study demonstrated that MRCP is a noninvasive examination for patients and that its popularization contributed to a reduction in medical costs. For further popularization of equipment and advanced imaging methods, careful assessment of examination costs is important.

Abstract
BACKGROUND AND STUDY AIMS Sphincter of Oddi manometry is considered to be the gold standard for diagnosing sphincter of Oddi dysfunction (SOD). Elevated basal sphincter pressures are found in about half of the patients with findings consistent with biliary type II SOD, and most of these patients will symptomatically improve after endoscopic sphincterotomy. Since manometric sphincter evaluation is not widely available, a decision analysis was used to compare the overall costs and outcomes of manometry-directed therapy with "empirical" sphincterotomy in patients with suspected biliary type II SOD. PATIENTS AND METHODS A decision analysis model was constructed using a software program. In a hypothetical cohort of 100 patients with suspected type II SOD, the following strategies were evaluated: a). endoscopic retrograde cholangiopancreatography (ERCP) with manometry followed by biliary sphincterotomy only if an elevated sphincter of Oddi basal pressure was found; and b). "empirical" biliary sphincterotomy without manometry. Data on the probability of an elevated sphincter of Oddi basal pressure at the time of ERCP in patients with suspected biliary SOD type II, the proportion of patients who improved after biliary sphincterotomy (with and without elevated basal pressures), the proportion of patients who improved without biliary sphincterotomy, complications, and death were obtained from the literature and from our center. The procedural and hospitalization costs represented the average Medicare reimbursement at our institution. The expected overall costs and numbers of patients improving with each strategy were compared.[nl] RESULTS The strategy of ERCP with manometry resulted in total costs of US dollars 2790 per patient, whereas a strategy of "empirical" biliary sphincterotomy resulted in total costs of US dollars 2244. In a cohort of 100 patients with suspected SOD, 55 % of patients would be expected to improve if manometry were performed, compared to 60 % of patients improving with "empirical" biliary sphincterotomy. Univariate sensitivity analyses demonstrated that "empirical" biliary sphincterotomy continued to be a cost-saving strategy in comparison with ERCP with manometry as long as the probability of spontaneous improvement in patients with "normal" manometry was less than 41 %, the probability of complications associated with manometry was greater than 6 %, and the probability of complications due to biliary sphincterotomy was less than 19 %. CONCLUSIONS For patients with suspected biliary SOD type II, empirical biliary sphincterotomy performed by experienced endoscopists appears to be cost-saving in comparison with a strategy based on the results of manometry.

Abstract
BACKGROUND:Data on current endoscopic retrograde cholangiopancreatography (ERCP) practice patterns drawn from large population-based samples are limited.METHODS:Patterns of ERCP use were determined using billing records for ERCP, sphincterotomy, stone extraction or stent placement performed between April 1, 1994 and March 31, 2002 in Alberta from a population-based administrative database. Age-sex adjusted rates (per 1000 population) were calculated using the 1991 Canadian population as the standard.RESULTS:The eight-year average ERCP rate was 0.98 without evidence of an increasing or decreasing trend over time. The ERCP rate was 0.85 in men and 1.12 in women. Significant regional variation in ERCP rates was seen, ranging from a low of 0.64 to a high of 1.27. The proportion of procedures that were therapeutic increased from 33% in 1994 to 70% in 2001. The likelihood of a procedure being considered therapeutic varied with the age and sex of the patient as well as the health region in which the procedure was performed.CONCLUSIONS:The ERCP rate remained relatively stable over an eight-year time period, but the proportion of procedures that were therapeutic increased dramatically. Important regional variation in ERCP rates and therapeutic procedures exists.

Abstract
RATIONALE AND OBJECTIVES This study was performed to assess the incremental cost-effectiveness of initial magnetic resonance cholangiopancreatography (MRCP) and initial endoscopic ultrasonography (EUS) compared with initial endoscopic retrograde cholangiopancreatography (ERCP) and to evaluate the effect of MRCP provider expertise on the relative cost-effectiveness of the three methods. MATERIALS AND METHODS Thirty patients with suspected biliary disease and referred for ERCP were prospectively evaluated with EUS, MRCP, or ERCP within 24 hours of referral, according to institutional review board-approved protocol. Performance characteristics were measured for EUS and MRCP, with ERCP as the reference standard. A decision analysis compared the clinical and economic effects of three diagnostic strategies (ERCP, EUS followed by ERCP [EUS-ERCP], and MRCP followed by ERCP [MRCP-ERCP]) using prospective EUS and MRCP test characteristics and Medicare reimbursements. The added costs per additional correct diagnosis and per additional false-positive finding averted and the rates and costs of ERCP-related complications were calculated for EUS-ERCP and MRCP-ERCP. Two additional MRCP readers reviewed MRCP data to evaluate interobserver variability and estimate provider expertise. Additional economic analyses incorporated these estimates. RESULTS Compared with initial ERCP, EUS-ERCP demonstrated 72% of biliary abnormalities and reduced ERCP-related complications by 60%; the corresponding percentages for MRCP-ERCP were 48% and 40%. Initial EUS and initial MRCP decreased the number of ERCP procedures performed by 69% and 49%, respectively. Each correct diagnosis made with ERCP that would not have been made with initial EUS or initial MRCP cost an additional 4,875 dollars or 2,580 dollars, respectively. Each false-positive diagnosis averted with initial ERCP that would have been made with EUS-ERCP or MRCP-ERCP cost an additional 9,750 dollars or 1,548 dollars, respectively. The decision model was most sensitive to disease prevalence. As provider expertise increased, the additional cost of an additional correct diagnosis increased for ERCP compared with MRCP-ERCP, with disease prevalence accentuating provider effects. CONCLUSION Initial EUS and initial MRCP are less costly than initial ERCP, but provider expertise, biliary disease prevalence, and procedural costs influence incremental cost-effectiveness.

Abstract
OBJECTIVES To establish the criteria that should be considered when analyzing the cost of digestive endoscopy and to determine how the variables studied influence the final results, as well as to determine the relative value unit (RVU) per endoscopic procedure. MATERIAL AND METHOD Clinical management study relating the cost of endoscopic procedures with their complexity, healthcare activity and direct and indirect countable costs. The endoscopic procedures performed from 2000-2001 (4,982 procedures) were analyzed. We determined the staff costs according to the hours devoted to endoscopic activity, the procedures performed and their complexity, non-amortizable and amortizable materials acquired in the study period, and the cost and amortization of apparatus and equipment. RESULTS The biannual cost was 392,892.60;. Staff costs were 63%, apparatus and equipment 15%, structural costs 13%, pharmacy 6%, materials 2% and amortizable materials 1%. The least expensive procedure was diagnostic gastroscopy (60.56;) and the most expensive was therapeutic endoscopic retrograde cholangiopancreatography (277.06;). The RVU cost was 52.58;. CONCLUSIONS Calculation of the cost of any medical procedure should take into account the strict application of direct and indirect costs. In our environment, the cost of endoscopy is lower than might be expected, mainly because the cost of amortization of apparatus and equipment and staff costs were low. Calculation of the complexity index is of considerable clinical and healthcare value. Determination of the RVU is a key element in establishing the cost of a procedure and in relating this cost with other costs, allowing its application as well as comparison among different investigations, services and centers.

Abstract
BACKGROUND Endoscopic screening of families predisposed to pancreatic cancer is increasingly used, but the cost-effectiveness of screening is unknown. METHODS A decision analysis was used to compare one-time screening for pancreatic dysplasia with EUS to no screening in a hypothetical cohort of 100 members of familial pancreatic cancer kindreds. Abnormal EUS findings are confirmed with ERCP and patients with abnormal findings are candidates for total pancreatectomy. Lifetime medical care costs and life expectancy were modeled, and the main analysis was conducted from the third-party payer perspective. The base-case analysis assumed a 20% prevalence of pancreatic dysplasia and 90% sensitivity of EUS and ERCP. RESULTS Endoscopic screening was cost-effective, with an incremental cost-effectiveness ratio of $16,885/life-year saved. Screening was more cost-effective as the probability of dysplasia increased and as the sensitivity of EUS and ERCP increased. Screening remained cost-effective if the prevalence of dysplasia was greater than 16% or if the sensitivity of EUS was greater than 84%. Procedure costs had a limited impact on cost-effectiveness. CONCLUSIONS Endoscopic screening of carefully selected members of familial pancreatic cancer kindreds appears to increase patient life expectancy in a cost-effective manner. Screening should be performed in centers that have experience with endoscopic screening for pancreatic dysplasia. The cost-effectiveness of repeated screening remains to be determined.

Abstract
BACKGROUND Total lifetime costs of endoscopic vs surgical treatment for obstructive jaundice due to cholangiocarcinoma are difficult to assess. The purpose of this study was to compare total costs in these two groups, including all treatment and retreatments. METHODS This retrospective study identified patients with biopsy-proven cholangiocarcinoma treated this decade with either endoscopic biliary stenting or surgical biliary-enteric bypass with or without resection. Outcomes and hospital charges were recorded. Ten matched control patients were compared from each group. Costs included those for cost of repeat endoscopy in the endoscopic group and for the management of recurrent obstructive jaundice in the surgical group. RESULTS The groups were similar in age and gender ratio. The surgical approach was frequently for cure; therefore, surgical patients were by and large at an earlier stage of their disease than those in the endoscopic group. Mean survival for the endoscopic group was 19 months vs 16.5 months for the surgical group. The median total lifetime cost for surgical therapy was $60,986 vs $24,251 for endoscopic therapy. CONCLUSION Endoscopic therapy is an effective palliative therapy for unresectable cholangiocarcinoma. Endoscopic therapy for this entity costs significantly less than surgical treatment. The cost benefit of endoscopic stenting over standard surgical bypass in the management of patients with unresectable cholangiocarcinoma, when considered along with its minimally invasive approach, makes this the procedure of choice for palliative therapy.

Abstract
OBJECTIVES The role of ERCP in acute biliary pancreatitis (ABP) is controversial. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography (EUS) are modalities for bile duct visualization that could lower costs and prevent ERCP-related complications. We analyzed costs and examined the cost-effectiveness of these modalities to define their role in ABP. METHODS A decision analysis model of ABP was constructed. The strategies evaluated were 1) ERCP, 2) MRCP followed by ERCP if positive for common bile duct stones (CBDS) or if biliary sepsis ensued, 3) EUS followed by ERCP if positive or if biliary sepsis ensued, and 4) observation with intraoperative cholangiography at the time of cholecystectomy with ERCP only if biliary sepsis ensued. We compared costs and performed cost-effectiveness analysis between strategies at probabilities of CBDS ranging from 0% to 100%. The outcome measures were total costs and costs per ABP death prevented. RESULTS At probabilities of CBDS < 15%, observation with intraoperative cholangiography is the least expensive strategy, whereas EUS and ERCP are the least expensive strategies at probabilities of 15-58% and >58%, respectively. In terms of cost-effectiveness, at probabilities of CBDS of 7-45%, EUS is the most cost-effective alternative, and at a probability of >45% ERCP is the most cost-effective option. CONCLUSIONS Total costs and cost-effectiveness ratios of these strategies in patients with ABP are highly dependent on the probability of CBDS.

Abstract
OBJECTIVES ERCP is the gold standard for pancreaticobiliary evaluation but is associated with complications. Less invasive diagnostic alternatives with similar capabilities may be cost-effective, particularly in situations involving low prevalence of disease. The aim of this study was to compare the performance of endoscopic ultrasound (EUS) with magnetic resonance cholangiopancreatography (MRCP) and ERCP in the same patients with suspected extrahepatic biliary disease. The economic outcomes of EUS-, MRCP-, and ERCP-based diagnostic strategies were evaluated. METHODS Prospective cohort study of patients referred for ERCP with suspected biliary disease. MRCP and EUS were performed within 24 h before ERCP. The investigators were blinded to the results of the alternative imaging studies. A cost-utility analysis was performed for initial ERCP, MRCP, and EUS strategies for these patients. RESULTS A total of 30 patients were studied. ERCP cholangiogram failed in one patient, and another patient did not complete MRCP because of claustrophobia. The final diagnoses (N = 28) were CBD stone (mean = 4 mm; range = 3-6 mm) in five patients; biliary stricture in three patients, and normal biliary tree in 20. Two patients had pancreatitis after therapeutic ERCP, one after precut sphincterotomy followed by a normal cholangiogram. EUS was more sensitive than MRCP in the detection of choledocolithiasis (80% vs 40%), with similar specificity. MRCP had a poor specificity and positive predictive value for the diagnosis of biliary stricture (76%/25%) compared to EUS (100%/100%), with similar sensitivity. The overall accuracy of MRCP for any abnormality was 61% (95% CI = 0.41-0.78) compared to 89% (CI = 0.72-0.98) for EUS. Among those patients with a normal biliary tree, the proportion correctly identified with each test was 95% for EUS and 65% for MRCP (p < 0.02). The cost for each strategy per patient evaluated was $1346 for ERCP, $1111 for EUS, and $1145 for MRCP. CONCLUSIONS In this patient population with a low disease prevalence, EUS was superior to MRCP for choledocholithiasis. EUS was most useful for confirming a normal biliary tree and should be considered a low-risk alternative to ERCP. Although MRCP had the lowest procedural reimbursement, the initial EUS strategy had the greatest cost-utility by avoiding unnecessary ERCP examinations.

Abstract
BACKGROUND The aim of this study was to show that laparoscopic cholecystectomy can be performed safely without routine intraoperative cholangiography. METHODS We performed a retrospective analysis of 1139 consecutive patients (376 men and 763 women with an average age of 51.4 years) who underwent laparoscopic cholecystectomy between 1991 and 1999. In all, 227 patients (20%) were selected to undergo preoperative endoscopic retrograde cholangiopancreatography (ERCP) on the basis of four criteria for risk of stones. RESULTS ERCP allowed us to make a diagnosis of biliary stones in 53.3% of the selected patients. Extraction of the stones was successful in 97% of the cases. In 14% of cases, ERCP was normal; in 32.7%, some useful diagnostic information was obtained. There were three complications (pancreatitis) following endoscopy (complication rate, 1.3%). Laparoscopic cholecystectomy was successful in 92% of patients. The postoperative morbidity rate was 3.2% (major complications, 0.5%). There were no deaths. During a follow-up period ranging from 3 to 97 months, six patients (0.6%) were found to have residual biliary stones. CONCLUSION This study confirms the hypothesis that laparoscopic cholecystectomy can be performed safely without routine intraoperative cholangiography.

Abstract
BACKGROUND AND STUDY AIMS Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) has been deemed to be a "cost-prohibitive" procedure, based upon the cumulative costs of one-time-use accessories and current reimbursement plans. One-time-use sphincterotomes comprise a significant component of that cost and, accordingly, we evaluated the disability and clinical usefulness of a recently introduced reusable double-channel sphincterotome. MATERIALS AND METHODS We studied a reusable 6-Fr sphincterotome at baseline and following contamination with 10(6) Bacillus stearothermophilus. Reprocessing included a unique 30-minute ultrasonic cleaning step in lieu of manual cleaning, followed by steam sterilization. Parameters evaluated included sphincterotome function, electrical integrity, and our ability to sterilize the devices for three in vitro trials. In vivo studies included patient demographics and outcomes, procedural findings, and success rates, and the mean number of times the sphincterotome was used, functional grading at time of use, and reasons for sphincterotome malfunction. RESULTS Ten out of ten sphincterotomes maintained form, function, and electrical integrity in vitro, and all cultures were negative after sterilization. In the initial in vivo study, ten sphincterotomes were used in 50 patients (mean, 5 uses) with a 94% success rate. Reasons for sphincterotome failure included leak or breakage of the accessory port in 70%, wire fracture in 10%, incorrect wire bow in 10%, and clogged injection port in 10%. Following reconfiguration of the insertion-port polymer, an additional ten sphincterotomes were used in 110 patients (mean, 11 uses). Mechanical failure occurred primarily at the wire-insertion port, resulting in progressive friction with reuse. There were neither electrical nor infectious complications associated with reuse. CONCLUSIONS A reusable double-channel sphincterotome is available which can theoretically be reprocessed and sterilized without the manual cleaning step of the reprocessing process. Contingent upon both provider and patient, multiple reuse can be anticipated, and contingent upon purchase price and reprocessing costs, the potential for procedural cost savings is significant.

Abstract
BACKGROUND A detailed analysis of the costs of ERCP is needed to provide medical staff, hospital administrators, and health care insurers with a solid basis for decision making. METHODS An incremental cost analysis was performed from the hospital perspective. Cost calculations were based on a prospective registration of materials, labor time, and equipment needed to perform 204 ERCPs in a tertiary care center. RESULTS Annual fixed cost related to the organization of the ERCP-unit amounted to $136,213. Variable costs per procedure, including labor and material costs, amounted to $344 and $961 for diagnostic and therapeutic procedures, respectively. Average reimbursement was $221. For the actual situation in our unit, with about 900 procedures yearly and a ratio diagnostic versus therapeutic procedures of 35 to 65, a net yearly loss because of the performance of ERCP activities amounts to $608,038. Theoretical measures to decrease costs could reduce this loss to $394,798, with an average loss of $439 per procedure. CONCLUSIONS This analysis of costs related to performance of ERCPs clearly shows that ERCP is not sufficiently reimbursed. From our model, it appears that increasing the reimbursement rate for therapeutic procedures to $600 per procedure would generate a net positive balance.
