Impact of Frailty on Early Readmissions of Endoscopic Retrograde Cholangiopancreatography in the United States: Where Do We Stand?

Background/Objectives: We assessed the impact of frailty on outcomes of endoscopic retrograde cholangiopancreatography (ERCP) in the United States. Methods: The National Readmission Database (2016-2020) was used to identify index and 30-day ERCP readmissions, which were categorized into low-frailty, intermediate-frailty, and high-frailty groups based on the Hospital Frailty Risk Score (HFRS). Outcomes were then compared. Results: Of 885,416 index admissions, 9.9% were readmitted within 30 days of ERCP. The odds of 30-day readmission were higher in the intermediate-frailty group (12.59% vs. 8.2%, odds ratio [OR] 1.67, 95% confidence interval [CI] 1.64-1.71, p < 0.001) and the high-frailty group (10.57% vs. 8.2%, OR 1.62, 95% CI 1.52-1.73, p < 0.001) compared to the low-frailty group. On readmission, a higher HFRS also increased mean length of stay (intermediate-frailty vs. low-frailty: 8.49 vs. 4.22 days, mean difference (MD) 4.26, 95% CI 4.19-4.34, p < 0.001; high-frailty vs. low-frailty: 10.9 vs. 4.22 days, MD 10.9 days, 95% CI 10.52-11.28, p < 0.001) and mean total hospitalization charges (intermediate-frailty vs. low-frailty: $118,996 vs. $68,034, MD $50,962, 95% CI 48, 854-53,069, p < 0.001; high-frailty vs. low-frailty: $195,584 vs. $68,034, MD $127,550, 95% CI 120,581-134,519, p < 0.001). The odds of inpatient mortality were also higher for the intermediate-frailty and high-frailty compared to the low-frailty subgroup. Conclusions: Frailty was associated with worse clinical outcomes after ERCP.

Comparison of ERCP Outcomes and Complication Risk between Elderly and Younger Patients: A Large Single-Center Study

Objectives: The current study compared potential risks, complications, and the impact on clinical outcomes among elderly and younger patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Methods: Procedure-related complications, risk factors, and clinical outcomes following complications in elderly patients (aged ≥75 years) and younger who underwent biliary ERCP were evaluated. Results: Median age of 63 (48–74) of 1164 patients who underwent biliary ERCP for the first time, and 266 (22.8%) were elderly. Comorbidities were statistically significant (81 [30.5%] versus 78 [8.7%], p &lt; 0.001), and periampullary diverticulum (PAD) was detected more commonly in the elderly group (79 [29.7%] vs. 103 [11.5%], p &lt; 0.001). There was no statistical difference in cannulation technique, cannulation time, and cannulation success in both groups, while the total ERCP procedure time was higher in the elderly group (22 [16–29] vs. 20 [14–29], p = 0.030). Regarding the procedure-related complications, there was no statistically significant difference between the two groups (26 [9.8%] vs. 71 [7.9%], p = 0.292). In the case of complications, the length of hospitalization stay was statistically longer in the elderly group. Moreover, the elderly had a longer length of hospitalization, experiencing pancreatitis and a higher probability of developing moderate/severe pancreatitis. In multivariate and univariate analysis, prolonged cannulation time was found to be an independent risk factor in patients ≥75 years of age. Conclusions: This study showed that while ERCP-related complication rates in elderly patients are comparable to younger patients, it can be associated with worse outcomes following the complication and prolonged length of hospitalization.

ThP4.7 - The outcome of a single stage Laparoendoscopic rendezvous ERCP and laparoscopic cholecystectomy for cholecystocholedocholithiasis in a DGH

Abstract Cholecystocholedocholithiasis is managed surgically by laparoscopic cholecystectomy (LC) and simultaneous common bile duct (CBD) exploration or by preoperative Endoscopic Retrograde Cholangiopancreatography (ERCP) followed by LC. Rendezvous ERCP (RERCP) is an innovative laparoendoscopic technique combining LCs and ERCPs. As a single staged procedure, a LC is performed and selective canulisation of the CBD is aided by laparoscopic transcystic placement of a guide-wire into the duodenum. We present a case series of RERCPs within a DGH. This case series collected retrospective data (2014-2023) involving 33 patients, of which 21 underwent RERCP. Preoperative variables included age, indication, gender, ASA grade, Charlson comorbidity index (CCI), frailty score and indication. Postoperative variables analysed were operating time, complications, 30-day re-admission rates and length of stay in hospital (LOSH). Of the 21 patients who underwent a RERCP, 76% (n=16) were female. The average age was 60±17years and 59% (n=13) of all procedures were elective. The ASA range was I to III, average CCI and frailty score were 2.4±1.9 and 0.1±0.4 respectively. 52% (n=11) of patients had a previous failed ERCP. The average operating time was 152±39mins. The average LOSH was 3.5±2.8days and 2.5±2.1days following the RERCP. Biliary (including pancreatitis) and non-biliary complications were 9.5% (n=2) and 9.5% (n=2) respectively. The 30-day readmission rate was 9.5% (n=2). There was no significant difference in the operating time (p=0.16), LOSH (p=0.19) complication (p=0.13) and readmission rates (p=0.50) between emergencies and elective procedures. RERCP remains a valuable option when managing cholecystocholedocholithiasis in emergency and elective settings.

Outcomes of endoscopic retrograde cholangiopancreatography performed in the AM versus PM: does procedural timing matter?

Abstract Background ERCP is a technically demanding procedure that carries a high cumulative adverse event (AE) rate of &amp;gt;10%. Identifying risk factors for adverse events is paramount. Procedure timing, as a surrogate for endoscopist fatigue, has been shown to influence key quality metrics in colonoscopy, but data on this relationship in ERCP is sparse. Methods We conducted a retrospective cohort study of ERCP procedures performed by 5 experienced staff endoscopists, with or without advanced endoscopy fellow (AEF) involvement, from January 1, 2010 to December 1, 2020 at St Michael’s Hospital, Toronto, Ontario, a regional referral center for therapeutic endoscopy. The primary outcome was the difference in rate of selective deep, duct canulation between AM and PM procedures. Results A total of 5672 ERCP procedures were eligible for inclusion. 2793 (49.2%) procedures were performed in the AM and 2879 procedures (50.8%) were performed in the PM. We found no significant difference in the rate of selective ductal cannulation between AM and PM procedures in the unadjusted (82.8% AM vs. 83.1% P-value = .79) or adjusted (OR = 0.98, 95% CI, 0.85-1.12, P-value = .72) analyses. We found no significant difference in the mean procedural duration or rate of perforation between AM and PM procedures. The rate of immediate bleeding was slightly higher in the AM cohort. Conclusion In our single-center retrospective study, ERCP quality, including selective cannulation rates and immediate adverse events were not significantly different in procedures performed in the morning compared to those performed in the afternoon.

Endoscopic retrograde cholangiopancreatography using a pediatric colonoscope in patients with Roux‑en‑Y gastrectomy and an intact major duodenal papilla.

Endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y gastrectomy and an intact major duodenal papilla is challenging and difficult, with unsatisfactory outcomes using various endoscopes. Limited data are available regarding the outcomes of ERCP using a pediatric colonoscope in such patients. To evaluate the efficacy of a pediatric colonoscope in patients with Roux-en-Y gastrectomy and an major duodenal intact papilla, 93 consecutive patients with Roux-en-Y gastrectomy and an intact major duodenal papilla who underwent ERCP using a pediatric colonoscope at the Medical Center for Digestive Diseases, The Second Affiliated Hospital of Nanjing Medical University, (Nanjing, China) between January 2018 and December 2022 were retrospectively reviewed. Following the failure of bile duct cannulation, a double-guidewire or precut technique was utilized for advanced cannulation. Interventions were performed using standard ERCP therapeutic accessories. The results indicated that distal gastrectomy with Roux-en-Y reconstruction was performed in 38 out of 93 patients, while 55 patients underwent total gastrectomy with Roux-en-Y reconstruction. The success rates associated with endoscope insertion, endoscopic cannulation and therapeutic ERCP were 88.17% (82/93), 85.37% (70/82) and 95.71% (67/70), respectively, while the clinical intervention success and complication rates were 72.04% (67/93) and 7.53% (7/93), respectively. The endoscope insertion time was 40.78±10.04 min, and the ERCP procedure time was 88.55±16.38 min. Student's t-test showed that the endoscope insertion time and the ERCP procedure time in patients undergoing distal gastrectomy were longer than those in patients undergoing total gastrectomy (P<0.05). Binary logistic regression analysis showed that age and number of previous abdominal surgeries were independent risk factors associated with endoscope insertion failure. In conclusion, the present study demonstrated that the use of a pediatric colonoscope is efficacious and safe for patients with Roux-en-Y gastrectomy and an intact major duodenal papilla undergoing ERCP.

ERCP-Related adverse events in pediatric patients: a 10-years single-site review.

This retrospective analysis aimed to assess the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric patients by examining ERCP-related adverse events (AEs) occurring over a decade at a single center. Pediatric patients under 18years old who underwent ERCP at the Second Hospital of Hebei Medical University from 1/2013 to 11/2023 were included. ERCP-related AEs were defined according to ERCP-related adverse events: European Society of Gastrointestinal Endoscopy (ESGE) Guideline. Clinical data of patients experiencing ERCP-related AEs were obtained from electronic medical records for analysis. Over the past decade, a total of 76 pediatric patients underwent 113 ERCP procedures, including 26 patients who underwent repeat ERCP, totaling 63 procedures. There were 32 males and 44 females, with a median age of 13years (range 3years and 5months-17years and 9months). Among all ERCP procedures, 14 (12.4%) were diagnostic and 99 (87.6%) were therapeutic, with a 100% success rate. 16 cases (14.2%) of ERCP-related AEs, all post-ERCP pancreatitis (PEP), were observed, while no other AEs defined by ESGE such as bleeding, perforation, cholangitis, cholecystitis, or sedation-related events were noted. Additionally, 23 cases (20.4%) of ERCP-related AEs not included in the ESGE definition were observed, including post-ERCP abdominal pain in 20 cases (17.7%), post-ERCP nausea and vomiting in 2 cases (1.8%), and unplanned reoperation in 1 case (0.9%). In the 26 cases of pediatric patients who underwent repeat ERCP, we observed that AEs occurred in 15 cases (57.7%) during their initial ERCP, which was much higher than the overall average level. Post-ERCP abdominal pain and PEP are the most common ERCP-related AEs in pediatric patients, while severe AEs such as bleeding and perforation are rare. The incidence of AEs after initial ERCP in pediatric patients who received repeat ERCP is higher than the overall average level. Based on our center's experience, we believe that ERCP can be safely performed in children over 3years old with biliary and pancreatic diseases and obtain reliable clinical benefits. However, active monitoring and management of ERCP-related AEs are essential to improve the clinical outcomes of pediatric ERCP.

Charting Unexplored Territories: ERCP Indications and Complications in Pediatric Patients; A Cross-Sectional Study from 2022 to 2023

Background: There are ongoing concerns about the safety of endoscopic retrograde cholangiopancreatography (ERCP) in children, as recorded cases have shown complications. Objectives: The objective of this study is to investigate the indications, complications, and outcomes of ERCP in pediatric patients. Methods: This cross-sectional study was conducted at Namazi and Abu Ali Sina Hospitals between September 2022 and December 2023. The study focused on pediatric patients aged 1 month to 18 years undergoing ERCP. The demographics, indications for ERCP, pre-procedural imaging findings, and complications within 72 hours and up to 6 months after ERCP were extracted from medical records. Results: During the study period, a total of 100 ERCP procedures were performed on 56 pediatric patients. The mean age of the patients was 10.22 ± 4.80 years, with females accounting for 53.6% of the group. The main indications for performing ERCP were the presence of a stricture after orthotopic liver transplantation (22%) and the presence of a common bile duct stone (19%). The incidence of complications was notable for acute pancreatitis (3%) and bleeding (2%), while the failure rate for ERCP operations was determined to be 4%. Conclusions: The infrequent occurrence of failures and complications highlights the substantial benefit of ERCP in treating biliary and pancreatic illnesses in children.

Is Routine Intraoperative Cholangiogram Necessary in Patients With Mild Acute Biliary Pancreatitis Undergoing Index Admission Cholecystectomy?

Background: There is controversy about whether intraoperative cholangiogram (IOC) should be performed routinely during laparoscopic cholecystectomy for patients with acute biliary pancreatitis, given significant false positive and negative rates and increased resource utilization. The aim of this study was to clarify the role of IOC in cases of mild biliary pancreatitis in patients undergoing index admission cholecystectomy, its impact on patient outcomes, and the impact of blood tests, imaging, and preoperative intervention on the detection of choledocholithiasis.Methods: A retrospective review of all patients presenting with acute mild biliary pancreatitis between January 2006 and December 2019 was conducted. Data collected included patient demographics, serum chemistry, IOC, and Endoscopic Retrograde Cholangiopancreatography (ERCP) findings, imaging findings, length of stay, operative length, and long-term follow-up outcomes.Results: 284 patients met the inclusion criteria for the study. The overall false positive IOC rate was 7.4%. Worsening bilirubin trend was a positive predictive value (PPV) for positive IOC and ERCP outcomes with a relative risk of 2.93 (P < .01) and 2.32 (P = .013), respectively. Improving preoperative bilirubin trend had a significant negative predictive value in IOC with a relative risk of .59 (P = .02). Positive IOC was shown to significantly increase operative length with a relative risk of 2.03 (P < .001).Discussion: A rising preoperative bilirubin is a predictor of a positive IOC and patients with normalizing bilirubin levels or a preoperative ERCP are less likely to have choledocholithiasis. These features may be used to select patients that would benefit from an IOC for index admission cholecystectomy.

The Influence of Symptomatic Status on Post-endoscopic Retrograde Cholangiopancreatography (ERCP) Complications in Choledocholithiasis: A Systematic Review and Meta-Analysis.

Choledocholithiasis presents variably, with some patients remaining asymptomatic, complicating decisions regarding the timing and necessity of endoscopic retrograde cholangiopancreatography (ERCP). This study represents the first meta-analysis assessing the impact of symptomatic status on post-ERCP complications and provides critical data to optimize treatment strategies. A systematic review and meta-analysis were conducted by searching PubMed, Embase, and Google Scholar through February 2024, focusing on comparing ERCP outcomes between symptomatic and asymptomatic patients with choledocholithiasis. Seven studies were included from an initial pool of 1,200 articles screened. The analysis revealed that asymptomatic patients exhibited a significantly higher overall complication rate (17.4% vs. 6.6%), including a threefold increase in the risk of developing complications overall (OR: 3.02; 95% CI: 2.26-4.03) and specifically post-ERCP pancreatitis (OR: 3.62; 95% CI: 2.63-4.99). Perforation and procedural durations were also notably higher among asymptomatic individuals. Subgroup analyses highlighted prolonged cannulation times and the use of precut sphincterotomy as potential influential factors. These findings challenge the current practice that does not differentiate based on symptomatic status and suggest a need for more tailored approaches in managing asymptomatic individuals to minimize risks associated with ERCP.

Outcomes of ERCP in Patients With Cystic Fibrosis: A Nationwide Inpatient Assessment.

Cystic fibrosis (CF) is a multisystem disorder that leads to abnormal transport of chloride and sodium across secretory epithelia resulting in thickened, viscous secretions in the bronchi, biliary tract, pancreas, intestine, and the reproductive system. Defects in the biliary tract can predispose to stone formation requiring endoscopic retrograde cholangiopancreatography (ERCP). However, there is a paucity of data assessing ERCP outcomes in patients with CF. We identified patients from the Healthcare Cost and Utilization Project (HCUP)-National Inpatient Sample (NIS) between the years 2016 and 2020. Our study group included patients with CF of all ages who underwent an inpatient ERCP. We used ICD10 diagnostic and procedural codes to identify patients, procedures, and complications of the procedure. From 2016 to 2020, a total of 860,679 inpatient ERCPs were identified. Of these procedures, 535 (0.06%) were performed in patients with CF. The mean age of patients with CF undergoing ERCP was 60.62 years, of which 48% were males and 52% were females. Patients in the CF group had a higher incidence of post-ERCP pneumothorax (0.93%) than the patients in the non-CF group (0.15%). The occurrence of other ERCP-related adverse events was similar in both groups (P>0.05). On multivariate regression analysis, patients with CF were 1.75 times more likely to develop post-ERCP infections [odds ratio (OR): 1.75; 95% CI: 1.03-2.94; P=0.035) and 7.64 times more likely to develop post-ERCP pneumothorax (OR: 7.64; 95% CI: 1.03-56.5; P=0.046) compared to patients without CF after adjusting for confounders. The groups had no significant difference in mortality, post-ERCP pancreatitis, bleeding, perforation, pneumoperitoneum, and gas embolism. There was also no significant difference in the length of stay between the study and control groups. ERCP is a safe procedure in patients with CF with a comparable risk of postprocedural complications and mortality to those who do not have cystic fibrosis. However, patients with CF may experience a higher risk of post-ERCP infections and post-ERCP pneumothorax. Further studies are needed to prospectively evaluate outcomes of ERCP in patients with CF and to determine methods of mitigating adverse events.

Morphology of the papilla can predict procedural safety and efficacy of ERCP—a systematic review and meta-analysis

Endoscopic Retrograde Cholangiopancreatography (ERCP) is the primary therapeutic procedure for pancreaticobiliary disorders, and studies highlighted the impact of papilla anatomy on its efficacy and safety. Our objective was to quantify the influence of papilla morphology on ERCP outcomes. We systematically searched three medical databases in September 2022, focusing on studies detailing the cannulation process or the rate of adverse events in the context of papilla morphology. The Haraldsson classification served as the primary system for papilla morphology, and a pooled event rate with a 95% confidence interval was calculated as the effect size measure. Out of 17 eligible studies, 14 were included in the quantitative synthesis. In studies using the Haraldsson classification, the rate of difficult cannulation was the lowest in type I papilla (26%), while the highest one was observed in the case of type IV papilla (41%). For post-ERCP pancreatitis, the event rate was the highest in type II papilla (11%) and the lowest in type I and III papilla (6–6%). No significant difference was observed in the cannulation failure and post-ERCP bleeding event rates between the papilla types. In conclusion, certain papilla morphologies are associated with a higher rate of difficult cannulation and post-ERCP pancreatitis.

Impact of frailty on endoscopic retrograde cholangiopancreatography outcomes in nonagenarians: A United States national experience.

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential therapeutic tool for biliary and pancreatic diseases. Frail and elderly patients, especially those aged ≥ 90 years are generally considered a higher-risk population for ERCP-related complications. To investigate outcomes of ERCP in the Non-agenarian population (≥ 90 years) concerning Frailty. This is a cohort study using the 2018-2020 National Readmission Database. Patients aged ≥ 90 were identified who underwent ERCP, using the international classification of diseases-10 code with clinical modification. Johns Hopkins's adjusted clinical groups frailty indicator was used to classify patients as frail and non-frail. The primary outcome was mortality, and the secondary outcomes were morbidity and the 30 d readmission rate related to ERCP. We used univariate and multivariate regression models for analysis. A total of 9448 patients were admitted for any indications of ERCP. Frail and non-frail patients were 3445 (36.46%) and 6003 (63.53%) respectively. Indications for ERCP were Choledocholithiasis (74.84%), Biliary pancreatitis (9.19%), Pancreatico-biliary cancer (7.6%), Biliary stricture (4.84%), and Cholangitis (1.51%). Mortality rates were higher in frail group [adjusted odds ratio (aOR) = 1.68, P = 0.02]. The Intra-procedural complications were insignificant between the two groups which included bleeding (aOR = 0.72, P = 0.67), accidental punctures/lacerations (aOR = 0.77, P = 0.5), and mechanical ventilation rates (aOR = 1.19, P = 0.6). Post-ERCP complication rate was similar for bleeding (aOR = 0.72, P = 0.41) and post-ERCP pancreatitis (aOR = 1.4, P = 0.44). Frail patients had a longer length of stay (6.7 d vs 5.5 d) and higher mean total charges of hospitalization ($78807 vs $71392) compared to controls (P < 0.001). The 30 d all-cause readmission rates between frail and non-frail patients were similar (P = 0.96). There was a significantly higher mortality risk and healthcare burden amongst nonagenarian frail patients undergoing ERCP compared to non-frail. Larger studies are warranted to investigate and mitigate modifiable risk factors.

A nomogram for prediction of ERCP success in patients with bile duct leaks: a multicenter study.

Bile duct leaks (BDLs) are serious complications that occurs after hepatobiliary surgery and trauma, leading to rapid clinical deterioration. Endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for BDLs, but it is not clear which patients will respond to this therapy and which patients will require additional surgical intervention. The aim of our study was to explore the predictors of successful ERCP for BDLs. A retrospective analysis was conducted using data from six centers' databases. All consecutive patients who were clinically confirmed as BDLs were included in the study. Collected data were demographics, disease severity, and ERCP procedure characteristics. Univariate and multivariate analysis were used to select independent predictive factors that affect the outcome of ERCP for BDLs, and a nomogram was established. Calibration and ROC curves were used to evaluate the models. Four hundred and forty-eight consecutive patients were clinically confirmed as BDLs and 347 were excluded. In the 101 patients included patients, clinical success was achieved in 78 patients (77.2%). In logistic multivariable regression, two independent factors were negatively associated with the success of ERCP: SIRS (OR, 0.183; 95% CI 0.039-0.864; P = 0.032) and high-grade leak (OR 0.073; 95% CI 0.010-0.539; P = 0.010). Two independent factors were positively associated with the success of ERCP: leak-bridging drainage (OR 4.792; 95% CI 1.08-21.21; P = 0.039) and cystic duct leak (OR 6.193; 95% CI 1.03-37.17; P = 0.046). The prediction model with these four factors was evaluated using a receiver-operating characteristic (ROC) curve, which demonstrated an area under the curve of 0.9351. The calibration curve showed that the model had good predictive accuracy. Leak-bridging drainage and cystic duct leak are positive predictors for the success of ERCP, while SIRS and high-grade leak are negative predictors. This prediction model with nomogram has good predictive ability and practical clinical value, and may be helpful in clinical decision-making and prognostication.

Safety and efficacy of endoscopic retrograde cholangiopancreatography in pediatric pancreatic and biliary disorders.

There is sparse data from India on indications, technical success, safety and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) using standard adult duodenoscope in the pediatric population. Retrospective analysis of prospectively maintained electronic endoscopy and clinical database was performed to identify pediatric patients (age ≤ 18years) who underwent ERCP between January 2017 and December 2022. Demographics and procedural details including indications, cholangio-pancreatogram findings, endotherapy type performed, technical and clinical success and complications were noted. As many as 150 pediatric patients were included of whom 88 had pancreatic (mean age-13.7years) and 62 had biliary disease (mean age- 14.9years). Common pancreatic ERCP indications were chronic pancreatitis (n = 45 [51.1%]), pancreatic duct disruption fistula (n = 21 [23.9%]) and recurrent acute pancreatitis (n = 16 [18.2%]). Among biliary indications were choledocholithiasis (n = 29 [46.8%]), benign bile duct strictures (n = 13 [21%]), bile duct injury/leak and biliary stent removal (n = 7 [11.3%]) , choledochal cyst (n = 5 [8.1%]) and pancreatic mass causing biliary compression (n = 1 [1.6%]). Technical success in pancreatic and biliary ERCP was 94.3% and 95.2%, respectively, and clinical success was 84.1% and 93.5%, respectively. Most common complications following pancreatic ERCPs were acute pancreatitis (n = 9 [10.2%]) (mild = 5, moderate = 4) patients and post sphincterotomy bleed in one (1.1%). Among biliary ERCPs, post ERCP pancreatitis was seen in (n = 3 [4.8%]) (mild = 2, moderate = 1). ERCP can be safely and effectively performed in children using standard duodenoscope. Chronic pancreatitis, choledocholithiasis and pancreatic divisum are common pediatric ERCP indications.

Analysis of the Effectiveness of Second Attempt Endoscopic Retrograde Cholangiopancreatography (ERCP) 24 Hours (Second Day) After Primary Failure.

Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive intervention that has established itself as the gold standard therapeutic option for various pancreaticobiliary conditions. Deep cannulation of the common bile duct (CBD) is essential in ERCP. However, cannulation is not possible in approximately 20% of the cases with the usual techniqueseven when performed by highly trained professionals or at major healthcare institutions. In case of failure on the first attempt, alternative choices include redoing the procedure (on the secondattempt) or moving on to more proficient endoscopic methods such as endoscopic ultrasound (EUS) or radiology-aided techniques (rendezvous procedures), totally percutaneous approaches, or surgical treatments. To analyze the effectiveness of the second attempt ERCP24 hours (second day) after primary failure. This analytical study was conducted to check the outcomes of second attempt ERCP in patients with prior failed cannulation, from June 20, 2023, to November 20,2023, at the Department of Gastroenterology, Lady Reading Hospital, Peshawar. Patients of either sex, aged >16 years with failed biliary cannulation, and who were otherwise clinically stable were included in the study. Patients with surgically modified anatomy, an unidentified main duodenal papilla, or a history of sphincterotomy at another setup were excluded. Outcomes were assessed in terms of gaining deep biliary access (cannulation) using a therapeutic duodenoscope and endoscopy system supported by a fluoroscope while using a wire-guided sphincterotome. Factors linked to second ERCP cannulation success or failure were analyzed using SPSS version 24. Ninety-four patients were enrolled including 61 (64.9%) males and 33 (35.10%) females. The mean age of the participants was 39.01±14.831 years. The most common indication for the intervention was CBDstones, which were present in 70 (74.5%) patients. Successful cannulation on the second attempt was achieved in 72 (76.6%) patients. Experienced endoscopists achieved a greater proportion of successful cannulation (86.8%) compared to 33.3% by endoscopists with lower experience (p-value: <0.001). Logistic regression analysis was conducted to predict the outcomes (cannulation), which revealed an odds ratio for endoscopist experience of 33.604 (95% confidence interval: 6.948-162.52). A second ERCP attempt24 hours after the primary failed attempt appears to be the best course of action for the majority of clinically stable patients.

Weekend endoscopic retrograde cholangiopancreatography has similar outcomes as weekday procedures-a propensity score match analysis of the Hungarian ERCP Registry.

Endoscopic retrograde cholangiopancreatography (ERCP) is essential for the minimally invasive management of biliary and pancreatic disorders. Under certain indications, performing ERCP without delay during the weekend can be important for improving outcomes. To compare the outcomes of ERCP performed on weekends and holidays with those of regular weekday ERCPs. Propensity score match analysis of the data from the Hungarian ERCP Registry. A total of 116 ERCPs were performed during weekends or holidays, and 3144 during weekday working hours. The analyses were performed on 1:2 propensity-matched groups (116 weekend and 232 weekday cases). Weekend ERCPs were mostly performed for acute cholangitis and acute biliary pancreatitis (70% of cases), whereas in the weekday group, only 32% of cases were performed for these indications. No significant difference was found between weekday and weekend ERCPs in terms of the rates of successful (91.38% vs 93.1%, p = 0.565) and difficult (33.62% vs 36.64%, p = 0.511) biliary cannulations. We found no significant differences in the number of adverse events (bleeding, post-ERCP pancreatitis, and 30-day mortality) in ERCPs performed during weekends or weekdays. Moreover, no significant differences in the aforementioned outcomes were detected between the propensity-matched groups. In this propensity-matched study, no significant differences were found in the outcomes of weekend and weekday ERCPs.

Retrospective analysis of clinical approaches in cases of perforation after endoscopic retrograde cholangiopancreatography

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a procedure in which endoscopy and fluoroscopy are used together to diagnose and treat problems in the pancreatic and biliary ductal systems. According to published studies, the frequency of perforation associated with ERCP is reported to be less than 1%. In our study, we aimed to retrospectively analyze the data of patients we followed after ERCP perforation to examine treatment approaches. In this study, data from 33 patients who underwent ERCP at a tertiary stage education and research hospital between November 2016 and April 2021 and were identified to have developed perforation during or after the procedure were retrospectively evaluated. The indications and outcomes of ERCP for patients, as well as laboratory and imaging findings, were analyzed in detail. The age distribution of the 33 patients included in the study ranged from 20 to 83 years, with a mean age of 57.1±17.6 years. Perforation developed during the initial ERCP procedure in 66.7% of the patients, and on seven of the ten patients in whom perforation was detected during the procedure, interventions were performed during the procedure. Although the mortality rate in patients with Stapfer type 1 or type 2 perforations (33.3%) was higher compared to the patients with type 3 or type 4 perforations (11.1%), the observed difference was not found to be statistically significant. In conclusion, the management of patients with ERCP perforation should be approached in a multidisciplinary manner, and non-operative approaches should always be considered in the appropriate patient population. Closely and dynamically monitoring of patients and algorithmic approaches should standardized.

Validity of a virtual reality endoscopic retrograde cholangiopancreatography simulator: can it distinguish experts from novices?

There is a lack of evidence regarding the effectiveness of virtual simulators as a means to acquire hands-on exposure to endoscopic retrograde cholangiopancreatography (ERCP). The present study aimed to assess the outcome and construct validity of virtual ERCP when training on the GI II Mentor simulator. A group of seven experienced endoscopists were compared with 31 novices. After a short introduction, they were requested to carry out three virtual ERCP procedures: diagnosing and removing a common bile duct (CBD) stone; diagnosing and taking brush cytology from a hilar stenosis; and, finally, diagnosing and treating a cystic leakage with a BD stent. For each task, the total time required to complete the task, time required to correctly view the papilla, total time of irradiation, time to deep cannulation, time to define diagnosis, time to complete sphincterotomy, and time to complete the respective intervention were measured. Cannulation of the BD, correct diagnosis, sphincterotomy, and time to complete intervention were assessed by an assessor blinded to the status of the endoscopist who performed the virtual ERCP. The time required to visualize the papilla and to cannulate deeply when removing the BD stone was significantly shorter for the experts (both p < 0.05). The time to visualize the papilla, cannulate deeply, reach a diagnosis, complete sphincterotomy, and complete the intervention was significantly shorter for the experts when managing cystic leakage (all p < 0.05). In diagnosing and taking brush cytology from a hilar stenosis, there was only a trend toward the experts needing less time for the deep cannulation of the BD (p = 0.077). The performance differed between experts and novices, especially in the management of cystic leakage. This corroborates the construct validity of the GI II Mentor simulator.

Comparison of Outcomes between a Basket Catheter and a Balloon Catheter for Endoscopic Common Bile Duct Stone Removal

Introduction: Evidence for the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) between a basket catheter and a balloon catheter for endoscopic common bile duct stone (CBDS) removal is lacking. This study aimed to compare ERCP outcomes using a basket catheter and a balloon catheter for endoscopic CBDS removal. Methods: This multicenter retrospective study included 904 consecutive patients with native papilla who underwent endoscopic stone removal for CBDS ≤10 mm using a basket catheter and/or a balloon catheter at three institutions in Japan. ERCP outcomes between the basket and balloon groups were compared using inverse probability of treatment weighting (IPTW) method. Results: ERCP-related adverse events occurred in 6.5% (29/449) and 7.7% (35/455) of patients in the basket and balloon groups, respectively (IPTW-adjusted p = 0.52). The incidences of post-ERCP pancreatitis, cholangitis, and perforation were similar in the basket and balloon groups (3.8% vs. 2.9%, 1.3% vs. 0.9%, and 0.7% vs. 0.7%, respectively). However, bleeding incidences were significantly higher in the balloon group than in the basket group (3.3% vs. 0.7%, IPTW-adjusted p = 0.012). Successful complete stone removal at one ERCP session using a single catheter was achieved in 17.8% (80/449) in the basket group and in 81.3% (370/455) in the balloon group (IPTW-adjusted p < 0.001). Discussion: A balloon catheter is more likely to complete stone extraction for CBDS ≤10 mm with a single catheter at one endoscopic stone removal session. However, the risk for post-ERCP bleeding is higher in the balloon group than in the basket group.
