Ustekinumab, a monoclonal antibody to the p40 subunit of interleukin-12 and interleukin-23, was evaluated as an intravenous induction therapy in two populations with moderately to severely active Crohn's disease. Ustekinumab was also evaluated as subcutaneous maintenance therapy.We randomly assigned patients to receive a single intravenous dose of ustekinumab (either 130 mg or approximately 6 mg per kilogram of body weight) or placebo in two induction trials. The UNITI-1 trial included 741 patients who met the criteria for primary or secondary nonresponse to tumor necrosis factor (TNF) antagonists or had unacceptable side effects. The UNITI-2 trial included 628 patients in whom conventional therapy failed or unacceptable side effects occurred. Patients who completed these induction trials then participated in IM-UNITI, in which the 397 patients who had a response to ustekinumab were randomly assigned to receive subcutaneous maintenance injections of 90 mg of ustekinumab (either every 8 weeks or every 12 weeks) or placebo. The primary end point for the induction trials was a clinical response at week 6 (defined as a decrease from baseline in the Crohn's Disease Activity Index [CDAI] score of ≥100 points or a CDAI score150). The primary end point for the maintenance trial was remission at week 44 (CDAI score150).The rates of response at week 6 among patients receiving intravenous ustekinumab at a dose of either 130 mg or approximately 6 mg per kilogram were significantly higher than the rates among patients receiving placebo (in UNITI-1, 34.3%, 33.7%, and 21.5%, respectively, with P≤0.003 for both comparisons with placebo; in UNITI-2, 51.7%, 55.5%, and 28.7%, respectively, with P0.001 for both doses). In the groups receiving maintenance doses of ustekinumab every 8 weeks or every 12 weeks, 53.1% and 48.8%, respectively, were in remission at week 44, as compared with 35.9% of those receiving placebo (P=0.005 and P=0.04, respectively). Within each trial, adverse-event rates were similar among treatment groups.Among patients with moderately to severely active Crohn's disease, those receiving intravenous ustekinumab had a significantly higher rate of response than did those receiving placebo. Subcutaneous ustekinumab maintained remission in patients who had a clinical response to induction therapy.

- Abstract
Gastroesophageal reflux disease (GERD) is one of the most common diseases that occurs secondary to failure of the antireflux barrier system, resulting in the frequent and abnormal reflux of gastric contents to the esophagus. GERD is diagnosed in routine clinical practice based on the classic symptoms of heartburn and regurgitation. However, a subset of patients with atypical symptoms can pose challenges in diagnosing GERD. An esophagogastroduodenoscopy (EGD) is the most common initial diagnostic test used in the assessment for GERD, although half of these patients will not have any positive endoscopic findings suggestive of GERD. The advanced endoscopic techniques have improved the diagnostic yield of GERD diagnosis and its complications, such as Barrett's esophagus and early esophageal adenocarcinoma. These newer endoscopic tools can better detect subtle irregularities in the mucosa and vascular structures. The management options for GERD include lifestyle modifications, pharmacological therapy, and endoscopic and surgical interventions. The latest addition to the armamentarium is the minimally invasive endoscopic interventions in carefully selected patients, including the electrical stimulation of the LES, Antireflux mucosectomy, Radiofrequency therapy, Transoral Incisionless Fundoplication, Endoscopic Full-Thickness plication (GERDx™), and suturing devices. With the emergence of these advanced endoscopic techniques, it is crucial to understand their selection criteria, advantages, and disadvantages.

- Abstract
Background Aims: Clinically significant post-endoscopic retrograde cholangiopancreatography (ERCP) bleeding (CSPEB) is common. Contemporary estimates of risk are lacking. We aimed to identify risk factors for and outcomes following CSPEB., Methods: We analyzed multi-center prospective ERCP data between 2018-2023 with 30-day follow-up. The primary outcome was CSPEB, defined as hematemesis, melena, or hematochezia resulting in: hemoglobin drop ≥20 g/L or transfusion and/or endoscopy to evaluate suspected bleeding, and/or unplanned healthcare visitation and/or prolongation of existing admission. Firth logistic regression was employed. P-values <0.05 were significant, with odds ratios (ORs) and 95% confidence intervals reported., Results: CSPEB occurred following 129 (1.5%) of 8,517 ERCPs (mean onset 3.2 days), with 110 of 4,849 events (2.3%) occurring following higher-risk interventions (sphincterotomy, sphincteroplasty, pre-cut sphincterotomy, and/or needle-knife access). CSPEB patients required endoscopy and transfusion in 86.0% and 53.5% of cases, respectively, with three cases (2.3%) being fatal. P2Y12 inhibitors were held for a median of 4 days (IQR 4) prior to higher-risk ERCP. Following higher-risk interventions, P2Y12 inhibitors (OR 3.33, 1.26-7.74), warfarin (OR 8.54, 3.32-19.81), dabigatran (OR 13.40, 2.06-59.96), rivaroxaban (OR 7.42, 3.43-15.24) and apixaban (OR 4.16, 1.99-8.20) were associated with CSPEB. Significant intraprocedural bleeding post sphincterotomy (OR 2.32, 1.06-4.60), but not post sphincteroplasty, was also associated. Concomitant cardiorespiratory events occurred more frequently within 30 days following CSPEB (OR 12.71, 4.75-32.54)., Conclusions: Risks of antiplatelet-related CSPEB may be underestimated by endoscopists based on observations of suboptimal holding before higher-risk ERCP. Appropriate periprocedural antithrombotic management is essential and could represent novel quality initiative targets., (Copyright © 2024 by The American College of Gastroenterology.)

- Abstract
A proportion of patients who undergo intraoperative cholangiogram (IOC) do not have bile duct stones at the time of endoscopic retrograde cholangiopancreatography (ERCP), either due to the spontaneous passage of stones or a false-positive IOC. Glucagon has been utilized as an inexpensive tool to allow the passage of micro-choledocholithiasis to the duodenum and resolve filling defects caused by stones or air bubbles. The purpose of our study is to understand the change in diagnostic accuracy of IOC to detect choledocholithiasis with intraoperative glucagon. We conducted a retrospective study at a tertiary care center on adult patients who underwent laparoscopic cholecystectomy with IOC. The diagnostic accuracy of IOC was assessed before and after the administration of intravenous glucagon. Of 1455 patients, 374 (25.7%) received intraoperative glucagon, and 103 of these 374 patients (27.5%) showed resolution of the filling defect with the passage of contrast to the duodenum. Pre- and post-glucagon administration comparison showed enhancement in specificity from 78% to 83%, an increase in positive predictive value from 67.3% to 72.4%, and an improvement in the diagnostic accuracy of IOC from 81.5% to 84.3%. Our findings suggest that intraoperative glucagon administration carries the potential to reduce the rate of false-positive IOCs, thereby reducing the performance of unnecessary ERCPs.

- Abstract
This joint ASGE-ESGE guideline provides an evidence-based summary and recommendations regarding the role of endoscopic bariatric and metabolic therapies (EBMTs) in the management of obesity. The document was developed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. It evaluates the efficacy and safety of EBMT devices and procedures that currently have CE mark or FDA-clearance/approval, or that had been approved within five years of document development. The guideline suggests the use of EBMTs plus lifestyle modification in patients with a BMI of ≥ 30 kg/m
2 , or with a BMI of 27.0-29.9 kg/m2 with at least 1 obesity-related comorbidity. Furthermore, it suggests the utilization of intragastric balloons and devices for endoscopic gastric remodeling (EGR) in conjunction with lifestyle modification for this patient population., Competing Interests: Disclosure The following authors disclosed financial relationships: P.

- Abstract
Adenoma detection rate (ADR) is challenging to measure, given its dependency on pathology reporting. Polyp detection rate (PDR) (percentage of screening colonoscopies detecting a polyp) is a proposed alternative to overcome this issue. Overall PDR from all colonoscopies is a relatively novel concept, with no large-scale studies comparing overall PDR with screening-only PDR. The aim of the study was to compare PDR from screening, surveillance, and diagnostic indications with overall PDR and evaluate any correlation between individual endoscopist PDR by indication to determine if overall PDR can be a valuable surrogate for screening PDR. Our study analyzed a prospectively collected national endoscopy database maintained by the National Institute of Health from 2009 to 2014. Out of 354,505 colonoscopies performed between 2009-2014, 298,920 ( n = 110,794 average-risk screening, n = 83,556 average-risk surveillance, n = 104,770 diagnostic) met inclusion criteria. The median screening PDR was 25.45 (IQR 13.15-39.60), comparable with the median overall PDR of 24.01 (IQR 11.46-35.86, p = 0.21). Median surveillance PDR was higher at 33.73 (IQR 16.92-47.01), and median diagnostic PDR was lower at 19.35 (IQR 9.66-29.17), compared with median overall PDR 24.01 (IQR 11.46-35.86; p < 0.01). The overall PDR showed excellent concordance with screening, surveillance, and diagnostic PDR (r > 0.85, p < 0.01, 2-tailed). The overall PDR is a reliable and pragmatic surrogate for screening PDR and can be measured in real time, irrespective of colonoscopy indication.

- Abstract
Background and Aims: Emerging data suggest neoadjuvant chemotherapy (NAC) for resectable pancreatic ductal adenocarcinoma (PDAC) is associated with improved survival. However, less than 40% of patients demonstrate a meaningful radiographic response to NAC. EUS-guided radiofrequency ablation (EUS-RFA) has emerged as a new modality to treat PDAC. We hypothesize that NAC plus EUS-RFA can be used in the management of resectable PDAC., Methods: This was a prospective review of PDAC patients meeting the criteria of resectable tumor anatomy who underwent NAC chemotherapy plus EUS-RFA followed by pancreatic resection. Radiographic imaging and perioperative and short-term outcomes were recorded. Surgical pathology specimens were analyzed for treatment response., Results: Three eligible patients with resectable PDAC received 4 months of NAC plus EUS-RFA. One month after completing NAC and EUS-RFA, all 3 patients underwent standard pancreaticoduodenectomy without adverse events. After a 6-week recovery, all patients completed 2 months of postoperative adjuvant chemotherapy., Conclusions: In our institutional experience, this treatment protocol appears to be safe as patients tolerated the combination of chemotherapy and ablation. Patients underwent pancreatic resection with uneventful recovery. This novel neoadjuvant approach may provide a more effective alternative to chemotherapy alone., Competing Interests: Disclosure The following author received research support for this study from Atilla Ertan MD Endowment funding: N.

Competing Interests: Disclosure N. Thosani is a consultant for Boston Scientific, consultant for and recipient of research support from Pentax America, speaker for Abbvie, recipient of royalties from UpToDate, and advisory board member for Colubris Rx. All other authors disclosed no financial relationships. Commentary Endoscopic resection of large colon polyps has largely replaced surgical resection. Polyps that occur at anastomotic sites or polyps that have been previously manipulated or partially resected can be challenging to remove endoscopically because of scarring. Novel therapies such as endoscopic submucosal dissection, endoscopic full-thickness resection, and the EndoRotor automated mechanical tissue resection device have been used successfully to remove complex, nonlifting polyps. In this case, the authors demonstrate the successful treatment of a large nonlifting polyp at a surgical anastomotic site using cryotherapy. Cryotherapy has been used in the past for treatment of Barrett’s esophagus, early esophageal neoplasia, gastric antral vascular ectasias, and flat duodenal polyps. This case demonstrates that cryotherapy can be added to our repertoire to successfully treat challenging, nonlifting colon polyps.

- Abstract
Background: Management of choledocholithiasis in patients with Roux-en-Y gastric bypass surgery is challenging. This study aims to compare technical success rates, adverse events, and procedural time between 3 current approaches: endoscopic ultrasound-directed transgastric Endoscopic retrograde cholangiopancreatography (ERCP) (EDGE), enteroscopy-assisted ERCP (E-ERCP), and laparoscopic-assisted ERCP (LA-ERCP)., Methods: A systematic search of 5 databases was conducted. Direct and network meta-analyses were performed to compare interventions using the random effects model. A significance threshold of P < 0.05 was applied., Results: Sixteen studies were included. On direct meta-analysis, technical success rates were comparable between EDGE and LA-ERCP (odds ratio: 0.768, CI: 0.196-3.006, P = 0.704, I2 = 14.13%). However, EDGE and LA-ERCP showed significantly higher success rates than E-ERCP. No significant differences in adverse events were found between EDGE versus LA-ERCP, EDGE versus E-ERCP, and LA-ERCP versus E-ERCP on direct meta-analysis. In terms of procedural time, EDGE was significantly shorter than E-ERCP [mean difference (MD): -31 minutes, 95% CI: -40.748 to -21.217, P < 0.001, I2 = 19.89%), and E-ERCP was shorter than LA-ERCP (MD: -44.567 minutes, 95% CI: -76.018 to -13.116, P = 0.005, I2 = 0%). EDGE also demonstrated a significant time advantage over LA-ERCP (MD: -78.145 minutes, 95% CI: -104.882 to -51.407, P < 0.001, I2 = 0%). All findings were consistent with network meta-analysis on random effects model. The heterogeneity of the model was low., Conclusions: EDGE and LA-ERCP showed superior technical success rates compared with E-ERCP. Adverse events did not significantly differ among the three approaches. Furthermore, EDGE demonstrated the shortest procedural duration. We recommend considering EDGE as a first-choice procedure., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Gastric cancer ranks as the fifth leading cause of global cancer incidences, exhibiting varied prevalence influenced by geographical, ethnic, and lifestyle factors, as well as Helicobacter pylori infection. The ATM gene on chromosome 11q22 is vital for genomic stability as an initiator of the DNA damage response, and mutations in this gene have been associated with various cancers. Poly ADP-ribose polymerase (PARP) inhibitors, such as olaparib, have shown efficacy in cancers with homologous recombination repair deficiencies, notably in those with ATM mutations. Here, we present a case of a 66-year-old patient with germline ATM-mutated metastatic gastric cancer with very high CA 19-9 (48 000 units/mL) who demonstrated an exceptional response to the addition of olaparib to chemo-immunotherapy and subsequent olaparib maintenance monotherapy for 12 months. CA 19-9 was maintained at low level for 18 months. Despite the failure of a phase II clinical trial on olaparib in gastric cancer (NCT01063517) to meet its primary endpoint, intriguing findings emerged in the subset of ATM-mutated patients, who exhibited notable improvements in overall survival. Our case underscores the potential clinical utility of olaparib in germline ATM-mutated gastric cancer and emphasizes the need for further exploration through larger clinical trials. Ongoing research and clinical trials are essential for optimizing the use of PARP inhibitors, identifying biomarkers, and advancing personalized treatment strategies for gastric cancer., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Perforations (Perf) during endoscopic retrograde cholangiopancreatography (ERCP) are rare (< 1%) but potentially fatal events (up to 20% mortality). Given its rarity, most data is through case series studies from centers or analysis of large databases. Although a meta-analysis has shown fewer adverse events as a composite (bleeding, pancreatitis, Perf) during ERCP performed at high-volume centers, there is very little real-world data on endoscopist and center procedural volumes, ERCP duration and complexity on the occurrence of Perf., Aim: To study the profile of Perf related to ERCP by center and endoscopist procedure volume, ERCP time, and complexity from a national endoscopic repository., Methods: Patients from clinical outcomes research initiative-national endoscopic database (2000-2012) who underwent ERCP were stratified based on the endoscopist and center volume (quartiles), and total procedure duration and complexity grade of the ERCP based on procedure details. The effects of these variables on the Perf that occurred were studied. Continuous variables were compared between Perf and no perforations (NoPerf) using the Mann-Whitney U test as the data demonstrated significant skewness and kurtosis., Results: A total of 14153 ERCPs were performed by 258 endoscopists, with 20 reported Perf (0.14%) among 16 endoscopists. Mean patient age in years 61.6 ± 14.8 vs 58.1 ± 18.8 (Perf vs . NoPerf, P = NS). The cannulation rate was 100% and 91.5% for Perf and NoPerf groups, respectively. 13/20 (65%) of endoscopists were high-volume performers in the 4
th quartile, and 11/20 (55%) of Perf occurred in centers with the highest volumes (4th quartile). Total procedure duration in minutes was 60.1 ± 29.9 vs 40.33 ± 23.5 (Perf vs NoPerf, P < 0.001). Fluoroscopy duration in minutes was 3.3 ± 2.3 vs 3.3 ± 2.6 (Perf vs NoPerf P = NS). 50% of the procedures were complex and greater than grade 1 difficulty. 3/20 (15%) patients had prior biliary surgery. 13/20 (65%) had sphincterotomies performed with stent insertion. Peritonitis occurred in only 1/20 (0.5%)., Conclusion: Overall adverse events as a composite during ERCP are known to occur at a lower rate with higher volume endoscopists and centers. However, Perf studied from the national database show prolonged and more complex procedures performed by high-volume endoscopists at high-volume centers contribute to Perf., Competing Interests: Conflict-of-interest statement: All the Authors have no conflict of interest related to the manuscript., (©The Author(s) 2023.

- Abstract
Introduction: The incremental yield of I-Scan virtual chromoendoscopy compared to high-definition white light endoscopy (HD-WLE) in detection of colorectal adenomas has not been thoroughly elucidated., Methods: A systematic search from inception to April 2023 was conducted to identify randomized controlled trials (RCTs) comparing I-Scan to HD-WLE for detection of adenomas. A random effects model was used to compute risk difference (RD) with corresponding 95% confidence intervals in adenoma detection rate (ADR). Influence analysis was done to assess robustness of findings. The number needed to diagnose was computed. Heterogeneity was assessed using the I
2 statistic and explored further by subgroup analyses defined a priori. Certainty in effect estimates was assessed using the GRADE approach., Results: We identified four studies (I-Scan n = 730, HD-WLE n = 765). I-Scan increased adenoma detection by 9% (risk difference (RD), 0.09; 0.04, 0.14; I2 02%; certainty, low). Influence analysis revealed that the gain in yield remained statistically significant with exclusion of all but one study. The number needed to capture one additional adenomatous polyp with I-Scan use was 11.2. I-Scan 1 use was associated with a statistically significant gain in ADR, whereas no significant difference in ADR was noted with I-Scan use on subgroup analysis., Discussion: In conclusion, I-Scan increases the yield of adenoma detection by 9% compared to HD-WLE, with low certainty in the estimate of this effect. Data on the gain in yield of detecting large polyps, sessile serrated lesions, and on the impact of formally training endoscopists and trainees in I-Scan use and similar technology on adenoma detection rate are needed., (© 2023.

- Abstract
Background and Aims: The relative utility of self-expanding metal stent (SEMS) insertion for malignant colon obstruction (MCO) due to extra-colonic malignancy (ECM) versus intra-colonic malignancy (ICM) is understudied., Methods: A systematic search was done from inception-April 2021 to identify reports of safety and efficacy of SEMS insertion for the treatment of MCO-ECM versus MCO-ICM. A meta-analysis of proportions, comparative meta-analysis to compute relative risks (RR), and mean differences (MD) was performed. Subgroup analyses and influence analyses were conducted. The certainty in estimates of effect(s) was assessed using the GRADE approach., Results: Eight non-randomized studies were identified; 46% (39-53%) and 63% (59-67%) of patients in the ECM and ICM groups were male. Most obstructions were in the rectosigmoid colon in both ECM and ICM groups. SEMS insertion in MCO-ECM was associated with an increased risk of technical failure compared to MCO-ICM (RR 2.92; 1.13-7.54; Certainty: Very Low). Risk of clinical failure of SEMS was higher in MCO-ECM compared to MCO-ICM (RR 2.88; 1.58-2.52; Certainty: Very Low). The risk of clinical failure remained significant throughout the influence analysis, as well as on subgroup analysis. There was no significant difference in the risk of adverse events or luminal perforation with SEMS insertion among patients with MCO-ECM and MCO-ICM. On influence analysis, removal of one study unveiled a significant increase in the risk of luminal perforation in MCO-ECM (RR 3.22; 1.44-7.19; p = 0.004)., Conclusion: SEMS for MCO-ECM may have a technical success rate comparable to or questionably worse than MCO-ICM, with low certainty in estimate of effects. SEMS deployment in MCO-ECM carries a higher risk of clinical failure, with a questionably higher risk of luminal perforation., (© 2023.

- Abstract
Background and Aims: Fluoroscopy-free endoscopic retrograde cholangiopancreatography for common bile duct stone (CBDS) clearance is usually offered only to pregnant patients. We initiated a multicenter, randomized controlled trial comparing clearance of non-complex CBDSs using fluoroscopy-free direct solitary cholangioscopy (DSC) to standard endoscopic retrograde cholangiography (ERC) to evaluate the wider applicability of the DSC-based approach. Here we report the initial results of stone clearance and safety in roll-in cases for the randomized controlled trial., Methods: Twelve expert endoscopists at tertiary care centers in four countries prospectively enrolled 47 patients with non-complex CBDSs for DSC-assisted CBDS removal in an index procedure including fluoroscopy-free cannulation. Successful CBDS clearance was first determined by DSC and subsequently validated by final occlusion cholangiogram as the ERC gold standard., Results: Fully fluoroscopy-free cannulation was successful in 42/47 (89.4%) patients. Brief fluoroscopy with minimal contrast injection was used in 4/47 (8.5%) patients during cannulation. Cannulation failed in 1/47 (2.1%) patients. Fluoroscopy-free complete stone clearance was reached in 38/46 (82.6%) cases. Residual stones were detected in the validation ERC occlusion cholangiogram in three cases. Overall serious adverse event rate was 2.1% (95% confidence interval 0.1-11.3): postprocedural pancreatitis in one patient., Conclusions: In patients with non-complex CBDS, the fluoroscopy-free technique is easily transferred to endoscopic retrograde cholangiopancreatography experts with acceptable rates of cannulation and stone clearance and few serious adverse events.

- Abstract
Background: Revision of a failed laparoscopic fundoplication carries higher risk of complication and lower chance of success compared to the original surgery. Transoral incisionless fundoplication (TIF) may be an endoscopic alternative for select GERD patients without need of a moderate/large hiatal hernia repair. The aim of this study was to assess feasibility, efficacy, and safety of TIF 2.0 after failed laparoscopic Nissen or Toupet fundoplication (TIFFF)., Methods: This is a multicenter retrospective cohort study of patients who underwent TIFFF between September 2017 and December 2020 using TIF 2.0 technique (EsophyX Z/Z+) performed by gastroenterologists and surgeons. Patients were included if they had (1) recurrent GERD symptoms, (2) pathologic reflux based upon pH testing or Grade C/D esophagitis or Barrett's esophagus, and (3) hiatal hernia ≤ 2 cm. The primary outcome was improvement in GERD Health-Related Quality of Life (GERD-HRQL) post-TIFFF. The TIFFF cohort was also compared to a similar surgical re-operative cohort using propensity score matching., Results: Twenty patients underwent TIFFF (median 4.1 years after prior fundoplication) and mean GERD-HRQL score improved from 24.3 ± 22.9 to 14.75 ± 21.6 (p = 0.014); mean Reflux Severity Index (RSI) score improved from 14.1 ± 14.6 to 9.1 ± 8.0 (p = 0.046) with 8/10 (80%) of patients with normal RSI (< 13) post-TIF. Esophagitis healed in 78% of patients. PPI use decreased from 85 to 55% with 8/20 (45%) patients off of PPI. Importantly, mean acid exposure time decreased from 12% ± 17.8 to 0.8% ± 1.1 (p = 0.028) with 9/9 (100%) of patients with normalized pH post-TIF. There were no statistically significant differences in clinical efficacy outcomes between TIFFF and surgical revision, but TIFFF had significantly fewer late adverse events., Conclusion: Endoscopic rescue with TIF is a safe and efficacious alternative to redo laparoscopic surgery in symptomatic patients with appropriate anatomy and objective evidence of persistent or recurrent reflux., (© 2023.

Cancer is one of the foremost health problems worldwide and is among the leading causes of death in the United States. Gastrointestinal tract cancers account for almost one third of the cancer-related mortality globally, making it one of the deadliest groups of cancers. Early diagnosis and prompt management are key to preventing cancer-related morbidity and mortality. With advancements in technology and endoscopic techniques, endoscopy has become the core in diagnosis and management of gastrointestinal tract cancers. In this extensive review, the authors discuss the role endoscopy plays in early detection, diagnosis, and management of esophageal, gastric, colorectal, pancreatic, ampullary, biliary tract, and small intestinal cancers., (© 2022 The Authors.

- Abstract
Background: Gastroesophageal reflux disease (GERD) is one of the most common diseases in North America and globally. The aim of this guideline is to provide evidence-based recommendations regarding the most utilized and available endoscopic and surgical treatments for GERD., Methods: Systematic literature reviews were conducted for 4 key questions regarding the surgical and endoscopic treatments for GERD in adults: preoperative evaluation, endoscopic vs surgical or medical treatment, complete vs partial fundoplication, and treatment for obesity (body mass index [BMI] ≥ 35 kg/m
2 ) and concomitant GERD. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed., Results: The consensus provided 13 recommendations. Through the development of these evidence-based recommendations, an algorithm was proposed for aid in the treatment of GERD. Patients with typical symptoms should undergo upper endoscopy, manometry, and pH-testing; additional testing may be required for patients with atypical or extra-esophageal symptoms. Patients with normal or abnormal findings on manometry should consider undergoing partial fundoplication. Magnetic sphincter augmentation or fundoplication are appropriate surgical procedures for adults with GERD. For patients who wish to avoid surgery, the Stretta procedure and transoral incisionless fundoplication (TIF 2.0) were found to have better outcomes than proton pump inhibitors alone. Patients with concomitant obesity were recommended to undergo either gastric bypass or fundoplication, although patients with severe comorbid disease or BMI > 50 should undergo Roux-en-Y gastric bypass for the additional benefits that follow weight loss., Conclusion: Using the recommendations an algorithm was developed by this panel, so that physicians may better counsel their patients with GERD. There are certain patient factors that have been excluded from included studies/trials, and so these recommendations should not replace surgeon-patient decision making. Engaging in the identified research areas may improve future care for GERD patients., (© 2022.

- Abstract
Background and study aims Concomitant hiatal hernia (HH) repair with transoral incisionless fundoplication (TIF) is a therapeutic option for patients with HH > 2 cm and gastroesophageal reflux disease (GERD). Data comparing this approach with laparoscopic Nissen fundoplication (LNF) are lacking. We performed an exploratory analysis to compare these two approaches' adverse events (AEs) and clinical outcomes. Patients and methods This was a multicenter retrospective cohort study of HH repair followed by LNF versus HH repair followed by TIF in patients with GERD and moderate HH (2-5 cm). AEs were assessed using the Clavien-Dindo classification. Symptoms (heartburn/regurgitation, bloating, and dysphagia) were compared at 6 and 12 months. Results A total of 125 patients with HH repair with TIF and 70 with HH repair with LNF were compared. There was no difference in rates of discontinuing or decreasing proton pump inhibitor use, dysphagia, esophagitis, disrupted wrap, and HH recurrence between the two groups ( P > 0.05). The length of hospital stay (1 day vs. 2 days), 30-day readmission rate (0 vs. 4.3 %), early AE rate (0 vs. 18.6 %), and early serious AE rate (0 vs. 4.3 %) favored TIF (all P < 0.05). The rate of new or worse than baseline bloating was lower in the TIF group at 6 months (13.8 % vs. 30.0 %, P = 0.009). Conclusions Concomitant HH repair with TIF is feasible and associated with lower early and serious AEs compared to LNF.

- Abstract
Background and study aims The optimal technique for removal of large common bile duct (CBD) stones (≥ 10 mm) during endoscopic retrograde cholangiopancreatography (ERCP) remains unclear. We aimed to perform a comparative analysis between different endoscopic techniques. Methods Adhering to PRISMA guidelines, a stringent search of the following databases through January 12, 2021, were undertaken: PubMed/Medline, Embase, Web of Science, and Cochrane. Randomized controlled trials comparing the following endoscopic techniques were included: (1) Endoscopic sphincterotomy (EST); (2) Endoscopic papillary large balloon dilation (EPLBD); and (3) EST plus large balloon dilation (ESLBD). Stone clearance rate (SCR) on index ERCP was the primary outcome/endpoint. Need for mechanical lithotripsy (ML) and adverse events were also evaluated as secondary endpoint. Random effects model and frequentist approach were used for statistical analysis. Results A total of 16 studies with 2545 patients (1009 in EST group, 588 in EPLBD group, and 948 patients in ESLBD group) were included. The SCR was significantly higher in ESLBD compared to EST risk ratio [RR]: 1.11, [confidence interval] CI: 1.00-1.24). Lower need for ML was noted for ESLBD (RR: 0.48, CI: 0.31-0.74) and EPLBD (RR: 0.58, CI: 0.34-0.98) compared to EST. All other outcomes including bleeding, perforation, post-ERCP pancreatitis, stone recurrence, cholecystitis, cholangitis, and mortality did not show significant difference between the three groups. Based on network ranking, ESLBD was superior in terms of SCR as well as lower need for ML and adverse events (AEs). Conclusions Based on network meta-analysis, ESLBD seems to be superior with higher SCR and lower need for ML and AEs for large CBD stones., Competing Interests: Competing interests N.

- Abstract
Background/aims: Current society guidelines recommend antibiotic prophylaxis for 3 to 5 days after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreatic cystic lesions (PCLs). The overall quality of the evidence supporting this recommendation is low. In this study, we aimed to assess cyst infection and adverse event rates after EUS-FNA of PCLs among patients treated with or without postprocedural prophylactic antibiotics., Methods: We retrospectively reviewed all patients who underwent EUS-FNA of PCLs between 2015 and 2019 at two large-volume academic medical centers with different practice patterns of postprocedural antibiotic prophylaxis. Data on patient demographics, cyst characteristics, fine-needle aspiration technique, periprocedural and postprocedural antibiotic prophylaxis, and adverse events were retrospectively extracted., Results: A total of 470 EUS-FNA procedures were performed by experienced endosonographers for the evaluation of PCLs in 448 patients, 58.7% of whom were women. The mean age was 66.3±12.8 years. The mean cyst size was 25.7±16.9 mm. Postprocedural antibiotics were administered in 274 cases (POSTAB+ group, 58.3%) but not in 196 cases (POSTAB- group, 41.7%). None of the patients in either group developed systemic or localized infection within the 30-day follow-up period. Procedure-related adverse events included mild abdominal pain (8 patients), intra-abdominal hematoma (1 patient), mild pancreatitis (1 patient), and perforation (1 patient). One additional case of pancreatitis was recorded; however, the patient also underwent endoscopic retrograde cholangiopancreatography., Conclusion: The incidence of infection after EUS-FNA of PCLs is negligible. Routine use of postprocedural antibiotics does not add a significant benefit.

This study aims to assess and compare practice patterns for following ASGE guidelines for choledocholithiasis in a large academic vs. community hospital setting., Methods: A total of one thousand ER indicated for choledocholithiasis were randomly selected. Patients' demographics, total bilirubin, imaging studies including magnetic resonance cholangiopancreatography (MRCP), intraoperative cholangiogram (IOC), endoscopic ultrasound (EUS), and ERCP results were retrospectively collected. Patients with prior sphincterotomy were excluded. We examined the following practice deviations from the current ASGE guidelines; (1) ERCP was potentially delayed in high probability cases while awaiting additional imaging studies, (2) ERCP was performed without additional imaging studies in cases of low/intermediate-risk, or (3) ERCP was performed in low/intermediate-risk cases when additional imaging studies were negative., Results: A total of 640 patients with native papilla who underwent ERCP were included in the final analysis. Overall, the management of 43% (275) of patients was deviated from the applicable ASGE guidelines. Academic and community provider rates of non-adherence were 32 vs. 45%, respectively ( p -value: < 0.01). Of 381 high-risk cases, 54.1% had additional imaging before ERCP. (Academic vs. community; 11.7 vs. 88.3%, p -value: < 0.01). In 26.7% (69/258) of low/intermediate risk cases, ERCP was performed without additional studies; academic (14.5%) vs. community (85.5%) ( p -value: < 0.01). Finally, in 11.2% (19/170) of patients, ERCP was performed despite intermediate/low probability and negative imaging; academic (26.3%) vs. community (73.7%) ( p -value: 0.02)., Conclusion: Our study results show that providers do not adhere to ASGE practice guidelines in 43% of suspected choledocholithiasis cases. The rate of non-adherence was significantly higher in community settings. It could be due to various reasons, including lack/delays for alternate studies (i.e., MRCP, EUS), concern regarding the length of stay, patient preference, or lack of awareness/understanding of the guidelines. Increased availability of alternate imaging and educational strategies may be needed to increase the adoption of practice guidelines across academic and community settings to improve patient outcomes and save healthcare dollars., Competing Interests: NT was a consultant for Boston-Scientific, Medtronic, Pentax America, received royalty from UpToDate, and was a speaker for Abbvie.

- Abstract
Long term prognosis and 5-year survival for pancreatic adenocarcinoma (PDAC) remains suboptimal. Endoscopic ultrasound (EUS) guided RFA (EUS-RFA) is an emerging technology and limited data exist regarding safety and long-term outcomes. The aim of this study is to report safety-profile, feasibility and outcomes of EUS-RFA for advanced PDAC. Prospective review of patients with diagnosis of locally-advanced or metastatic PDAC undergoing EUS-RFA between October 2016 to March 2018 with long-term follow up (> 30 months). Study patients underwent a total of 1-4 RFA sessions. All patients were enrolled in longitudinal cohort study and received standard of care chemotherapy. 10 patients underwent EUS-RFA. Location of the lesions was in the head(4), neck(2), body(2), and tail(2). 22 RFA sessions were performed with a range of 1-4 sessions per patient. There were no major adverse events (bleeding, perforation, infection, pancreatitis) in immediate (up to 72 h) and short-term follow up (4 weeks). Mild worsening of existing abdominal pain was noted during post-procedure observation in 12/22 (55%) of RFA treatments. Follow-up imaging demonstrated tumor progression in 2 patients, whereas tumor regression was noted in 6 patients (> 50% reduction in size in 3 patients). Median survival for the cohort was 20.5 months (95% CI, 9.93-42.2 months). Currently, 2 patients remain alive at 61 and 81 months follow-up since initial diagnosis. One patient had 3 cm PDAC with encasement of the portal confluence, abutment of the celiac axis, common hepatic and superior mesenteric artery. This patient had significant reduction in tumor size and underwent standard pancreaticoduodenectomy. In our experience, EUS-RFA was safe, well-tolerated and could be concurrently performed with standard chemotherapy. In this select cohort, median survival was improved when compared to published survival based upon SEER database and clinical trials. Future prospective trials are needed to understand the role of EUS-RFA in overall management of PDAC., (© 2022. The Author(s).)

- Abstract
(1) Background: Various methods to predict the presence or absence of choledocholithiasis (CDL) have been proposed. We aimed to assess the performance characteristics of dynamic liver enzyme trends in the prediction of CDL. (2) Methods: This was a single-center retrospective cohort study. All adult in-patients undergoing endoscopy for suspected CDL between 1 January 2012 and 7 October 2018 were identified, with patients with prior cholecystectomy, prior sphincterotomy, or indwelling biliary prostheses were excluded. Available laboratory parameters within 72 h preceding the procedure were recorded, allowing for the assessment of trends. Dynamic enzyme trends were defined as any increase or decrease by 30% and 50% within 72 h of the index procedure. (3) Results: A total of 878 patients were included. Mean age was 61.8 years, with 58.6% female. Increases in alkaline phosphatase (ALP) of at least 30% or 50% were both specific for the presence of CDL, with specificities of 82.7% (95% CI 69.7-91.8%) and 88.5% (95% CI 76.6-95.6%), respectively. Decreases in bilirubin or ALP of at least 50% were highly specific for the absence of CDL, with specificities of 91.7% (95% CI 85.7-95.8%) and 100.0% (97.2-100.0%), respectively. (4) Conclusions: Several liver enzyme trends appear to be specific for the absence or presence of stones; in particular, significant decreases in total bilirubin or ALP of at least 30-50% over the prior 72 h appear to be especially predictive of an absence of intraductal findings during endoscopy.

- Abstract
Background and study aims Post-ERCP pancreatitis (PEP) is the most common complication attributed to the procedure, its incidence being approximately 9.7 %. Numerous studies have evaluated the predictive efficacy of post-procedure serum amylase and lipase levels but with varied procedure-to-test time intervals and cut-off values. The aim of this meta-analysis was to present pooled data from available studies to compare the predictive accuracies of serum amylase and lipase for PEP. Patients and methods A total of 18 studies were identified after a comprehensive search of various databases until June 2021 that reported the use of pancreatic enzymes for PEP. Results The sample size consisted of 11,790 ERCPs, of which PEP occurred in 764 (6.48 %). Subgroups for serum lipase and amylase were created based on the cut-off used for diagnosing PEP, and meta-analysis was done for each subgroup. Results showed that serum lipase more than three to four times the upper limit of normal (ULN) performed within 2 to 4 hours of ERCP had the highest pooled sensitivity (92 %) for PEP. Amylase level more than five to six times the ULN was the most specific serum marker with a pooled specificity of 93 %. Conclusions Our analysis indicates that a lipase level less than three times the ULN within 2 to 4 hours of ERCP can be used as a good predictor to rule out PEP when used as an adjunct to patient clinical presentation. Multicenter randomized controlled trials using lipase and amylase are warranted to further evaluate their PEP predictive accuracy, especially in high-risk patients., Competing Interests: Competing interests Hemant Goyal: Aimloxy LLC.

- Abstract
Background and study aims Duodenoscopes that are contaminated due to inadequate reprocessing are well-documented. However, studies have demonstrated poor reprocessing of other kinds of endoscopes as well, including echoendoscopes, gastroscopes, and colonoscopes. We estimated the contamination rate beyond the elevator of gastrointestinal endoscopes based on available data. Methods We searched PubMed and Embase from January 1, 2010 to October 10, 2020, for studies investigating contamination rates of reprocessed gastrointestinal endoscopes. A random-effects model was used to calculate the contamination rate of patient-ready gastrointestinal endoscopes. Subgroup analyses were conducted to investigate differences among endoscope types, countries, and colony-forming unit (CFU) thresholds. Results Twenty studies fulfilled the inclusion criteria, including 1,059 positive cultures from 7,903 samples. The total contamination rate was 19.98 % ± 0.024 (95 % confidence interval [Cl]: 15.29 %-24.68 %; I
2 = 98.6 %). The contamination rates of colonoscope and gastroscope channels were 31.95 % ± 0.084 and 28.22 % ± 0.076, respectively. Duodenoscope channels showed a contamination rate of 14.41 % ± 0.029. The contamination rates among studies conducted in North America and Europe were 6.01 % ± 0.011 and 18.16% ± 0.053 %, respectively. The contamination rate among studies using a CFU threshold > 20 showed contamination of 30.36 % ± 0.094, whereas studies using a CFU threshold < 20 showed a contamination rate of 11 % ± 0.026. Conclusions On average, 19.98 % of reprocessed gastrointestinal endoscopes may be contaminated when used in patients and varies between different geographies. These findings highlight that the elevator mechanism is not the only obstacle when reprocessing reusable endoscopes; therefore, guidelines should recommend more surveillance of the endoscope channels as well., Competing Interests: Competing interests Hemant Goyal serves as a consultant for Aimloxy LLC.Sara Larsen, Lotte Klinten Ockert, and Dr. Sven Adamsen are employed by Ambu A/S.

- Abstract
Over 17.7 million gastrointestinal (GI) endoscopic procedures are performed annually, contributing to 68% of all endoscopic procedures in the United States. Usually, endoscopic procedures are low risk, but adverse events may occur, including cardiopulmonary complications, bleeding, perforation, pancreatitis, cholangitis, and infection. Infections after the GI endoscopies most commonly result from the patient's endogenous gut flora. Although many studies have reported infection after GI endoscopic procedures, a true estimate of the incidence rate of post-endoscopy infection is lacking. In addition, the infection profile and causative organisms have evolved over time. In recent times, multi-drug-resistant microorganisms have emerged as a cause of outbreaks of endoscope-associated infections (EAI). In addition, lapses in endoscope reprocessing have been reported, with some but not all outbreaks in recent times. This systematic review summarizes the demographical, clinical, and management data of EAI events reported in the literature. A total of 117 articles were included in the systematic review, with the majority reported from North America and Western Europe. The composite infection rate was calculated to be 0.2% following GI endoscopic procedures, 0.8% following ERCP, 0.123% following non-ERCP upper GI endoscopic procedures, and 0.073% following lower GI endoscopic procedures. Pseudomonas aeruginosa was the most common culprit organism, followed by other Enterobacteriaceae groups of organisms and Gram-positive cocci. We have also elaborated different prevention methods such as antimicrobial prophylaxis, adequate sterilization methods for reprocessing endoscopes, periodic surveillance, and current evidence supporting their utilization. Finally, we discuss disposable endoscopes, which could be an alternative to reprocessing to minimize the chances of EAIs with their effects on the environmental and financial situation., (© 2022.

- Abstract
Background: Pancreatic cancer (PC) is a highly fatal malignancy with a global overall 5-year survival of under 10%. Screening of PC is not recommended outside of clinical trials. Endoscopic ultrasonography (EUS) is a very sensitive test to identify PC but lacks specificity and is operator-dependent, especially in the presence of chronic pancreatitis (CP). Artificial Intelligence (AI) is a growing field with a wide range of applications to augment the currently available modalities. This study was undertaken to study the effectiveness of AI with EUS in the diagnosis of PC., Methods: Studies from MEDLINE and EMBASE databases reporting the AI performance applied to EUS imaging for recognizing PC. Data were analyzed using descriptive statistics. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool was used to assess the quality of the included studies., Results: A total of 11 articles reported the role of EUS in the diagnosis of PC. The overall accuracy, sensitivity, and specificity of AI in recognizing PC were 80-97.5%, 83-100%, and 50-99%, respectively, with corresponding positive predictive value (PPV) and negative predictive value (NPV) of 75-99% and 57-100%, respectively. Types of AI studied were artificial neural networks (ANNs), convolutional neural networks (CNN), and support vector machine (SVM). Seven studies using other than basic ANN reported a sensitivity and specificity of 88-96% and 83-94% to differentiate PC from CP. Two studies using SVM reported a 94-96% sensitivity, 93%-99% specificity, and 94-98% accuracy to diagnose PC from CP. The reported sensitivity and specificity of detection of malignant from benign Intraductal Papillary Mucinous Neoplasms (IPMNs) was 96% and 92%, respectively., Conclusion: AI reported a high sensitivity with high specificity and accuracy to diagnose PC, differentiate PC from CP, and differentiate benign from malignant IPMN when used with EUS., Competing Interests: Conflict of interest statement: The authors declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Hemant Goyal – Consultant for Aimloxy LLC., (© The Author(s), 2022.)

- Abstract
Background and Aims: EUS, MRCP, and intraoperative cholangiogram (IOC) are the recommended diagnostic modalities for patients with intermediate probability for choledocholithiasis (IPC). The relative cost-effectiveness of these modalities in patients with cholelithiasis and IPC is understudied., Methods: We developed a decision tree for diagnosing IPC (base-case probability, 50%; range, 10%-70%); patients with a positive test were modeled to undergo therapeutic ERCP. The strategies tested were laparoscopic cholecystectomy with IOC (LC-IOC), MRCP, single-session EUS + ERCP, and separate-session EUS + ERCP. Costs and probabilities were extracted from the published literature. Effectiveness was assessed by assigning utility scores to health states, average proportion of true-positive diagnosis of IPC, and the mean length of stay (LOS) per strategy. Cost-effectiveness was assessed by extrapolating a net-monetary benefit (NMB) and average cost per true-positive diagnosis., Results: LC-IOC was the most cost-effective strategy to diagnose IPC (base-case probability of 50%) among patients with cholelithiasis in health state-based effectiveness analysis (NMB of $34,612), diagnostic test accuracy-based effectiveness analysis (average cost of $13,260 per true-positive diagnosis), and LOS-based effectiveness analysis (mean LOS of 4.13) compared with strategies 2 (MRCP), 3 (single-session EUS + ERCP), and 4 (separate-session EUS + ERCP). These findings were robust on deterministic and probabilistic sensitivity analyses., Conclusions: For patients with cholelithiasis with IPC, LC-IOC is a cost-effective approach that should limit preoperative testing and may shorten hospital LOS. Our findings may be used to design institutional and organizational management protocols., (Copyright © 2022 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

- Abstract
Background: Over the last few decades, advances have been made regarding gender equality starting from medical students to trainees, to leadership in academics. The female representation in specialty academic conferences not only reflects the existing gender disparities in that specialty but also can influence young female trainees to join that field. Digestive Disease Week (DDW) is the premier digestive disease event. We aimed to calculate the proportion of female representation among speakers and moderators at the DDW meetings held from 2018 to 2020., Methods: The data for DDW 2018-2020 were collected via the online web-based planner. The gender of speakers of presentations and moderators of sessions were identified by a google search. We further categorized the data by each participating society (AGA, ASGE, AASLD, and SSAT), by presentation track, by session track, and total overall representation in each year., Results: Despite the subject of the gender gap being in focus, the proportion of female moderators and speakers was low in DDW in the last 3 years. The female speakers constituted 31.6% in 2018, 33.8% in 2019 and 34.6% in 2020. There was slightly improved female representation in sessions of Inflammatory Bowel Disease, Stomach, and Small Bowel Disorders, Microbiome in GI & Liver disease, and Basic Science over the last 3 years., Conclusion: Based on our study and those referenced in this article, we believe that strategies to promote the inclusivity of female moderators and speakers at DDW provide a huge opportunity to influence gender equity within GI., (© 2021.

- Abstract
Background and study aims Transoral incisionless fundoplication (TIF) is a safe and effective minimally invasive endoscopic technique for treating gastroesophageal reflux disease (GERD). The learning curve for this technique has not been reported. We studied the learning curve for TIF when performed by a gastroenterologist by identifying the threshold number of procedures needed to achieve consistent technical success or proficiency (consistent creation of TIF valve ≥ 270 degrees in circumference, ≥ 2 cm long) and efficiency after didactic, hands-on and case observation experience. Patients and methods We analyzed prospectively collected data from patients who had TIF performed by a single therapeutic endoscopist within 17 months after basic training. We determined thresholds for procedural learning using cumulative sum of means (CUSUM) analysis to detect changes in achievement rates over time. We used breakpoint analysis to calculate procedure metrics related to proficiency and efficiency. Results A total of 69 patients had 72 TIFs. The most common indications were refractory GERD (44.7 %) and proton pump inhbitor intolerance (23.6 %). Proficiency was achieved at the 18
th to 20th procedure. The maximum efficiency for performing a plication was achieved after the 26th procedure, when mean time per plication decreased to 2.7 from 5.1 minutes (P < 0.0001). TIF procedures time varied until the 44th procedure, after which it decreased significantly from 53.7 minutes to 39.4 minutes (P < 0.0001). Conclusions TIF can be safely, successfully, and efficiently performed in the endoscopy suite by a therapeutic endoscopist. The TIF learning curve is steep but proficiency can be achieved after a basic training experience and 18 to 20 independently performed procedures., Competing Interests: Competing interests Dr. Ngamruengphong is a consultant for Boston Scientific.

- Abstract
Gastrointestinal cancers are among the leading causes of death worldwide, with over 2.8 million deaths annually. Over the last few decades, advancements in artificial intelligence technologies have led to their application in medicine. The use of artificial intelligence in endoscopic procedures is a significant breakthrough in modern medicine. Currently, the diagnosis of various gastrointestinal cancer relies on the manual interpretation of radiographic images by radiologists and various endoscopic images by endoscopists. This can lead to diagnostic variabilities as it requires concentration and clinical experience in the field. Artificial intelligence using machine or deep learning algorithms can provide automatic and accurate image analysis and thus assist in diagnosis. In the field of gastroenterology, the application of artificial intelligence can be vast from diagnosis, predicting tumor histology, polyp characterization, metastatic potential, prognosis, and treatment response. It can also provide accurate prediction models to determine the need for intervention with computer-aided diagnosis. The number of research studies on artificial intelligence in gastrointestinal cancer has been increasing rapidly over the last decade due to immense interest in the field. This review aims to review the impact, limitations, and future potentials of artificial intelligence in screening, diagnosis, tumor staging, treatment modalities, and prediction models for the prognosis of various gastrointestinal cancers.

- Abstract
Background: Endoscopic ultrasonography (EUS)-guided liver biopsy is a novel technique to obtain adequate liver samples for diagnosis of liver parenchymal diseases. There are studies that have evaluated the feasibility and safety of EUS-guided parenchymal liver biopsy (EUS-LB), however, factors that can influence specimen quality are yet to be determined. Our aim was to determine the diagnostic accuracy of EUS-LB and evaluate factors associated with specimen quality., Methods: We performed a detailed search of PubMed/MEDLINE and Web of Science™ databases to identify studies in which results of EUS-guided liver parenchymal biopsies were reported published up to July 2020. A random effects model was used to estimate pooled values (mean ± SE) for total specimen length (TSL) and complete portal tracts (CPT). Subgroup analyses were applied to find out the procedural factors associated with better specimen quality using Cochran's Q test. A total of 10 meta-analyses were done focusing on international studies. Total of 1326 patients who underwent EUS-LB. EUS-LBs performed for suspicion of parenchymal liver disease. Pooled mean values for TSL and CPT with subgroup analyses., Results: Twenty-three studies with a total of 1326 patients were included in our meta-analysis. Overall pooled mean TSL and CPT were 45.3 ± 4.6 mm and 15.8 ± 1.5, respectively. In subgroup analysis, core biopsy needles proved to better in terms of CPT than fine-needle aspiration needles (18.4 vs 10.99, p = 0.003). FNB with slow-pull or suction technique provided a similar TSL (44.3 vs 53.9 mm, p = 0.40), however, slow-pull technique was better in terms of CPT (30 vs 14.6, p < 0.001). Heterogeneity was present among the studies. Another limitation is the low number randomized control trials., Conclusion: EUS-guided parenchymal liver biopsy is a good alternative to other methods of liver sampling. Using FNB needles with a slow-pull technique can provide better results., (© 2020. Springer Science+Business Media, LLC, part of Springer Nature.)

- Abstract
Background: Gastroesophageal Reflux Disease (GERD) is an extremely common condition with several medical and surgical treatment options. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians, patients, and others in decisions regarding the treatment of GERD with an emphasis on evaluating different surgical techniques., Methods: Literature reviews were conducted for 4 key questions regarding the surgical treatment of GERD in both adults and children: surgical vs. medical treatment, robotic vs. laparoscopic fundoplication, partial vs. complete fundoplication, and division vs. preservation of short gastric vessels in adults or maximal versus minimal dissection in pediatric patients. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed., Results: The panel provided seven recommendations for adults and children with GERD. All recommendations were conditional due to very low, low, or moderate certainty of evidence. The panel conditionally recommended surgical treatment over medical management for adults with chronic or chronic refractory GERD. There was insufficient evidence for the panel to make a recommendation regarding surgical versus medical treatment in children. The panel suggested that once the decision to pursue surgical therapy is made, adults and children with GERD may be treated with either a robotic or a laparoscopic approach, and either partial or complete fundoplication based on surgeon-patient shared decision-making and patient values. In adults, the panel suggested either division or non-division of the short gastric vessels is appropriate, and that children should undergo minimal dissection during fundoplication., Conclusions: These recommendations should provide guidance with regard to surgical decision-making in the treatment of GERD and highlight the importance of shared decision-making and patient values to optimize patient outcomes. Pursuing the identified research needs may improve future versions of guidelines for the treatment of GERD., (© 2021.

- Abstract
Introduction: Antithrombotic therapy is often interrupted before the placement of a percutaneous endoscopic gastrostomy (PEG) tube because of potentially increased risk of hemorrhagic events. The aim of our study was to evaluate the risk of bleeding events and overall complication rates after PEG in patients on uninterrupted antiplatelet and anticoagulation therapy in a high-volume center., Methods: Data regarding demographics, diagnoses, comorbidities, and clinical outcomes pertinent to PEG were collected from 2010 to 2016. Furthermore, data regarding antithrombotic therapy along with the rate of minor or major complications including bleeding associated with this procedure were analyzed. Significant bleeding was defined as postprocedure bleeding from PEG site requiring a blood transfusion and/or surgical/endoscopic intervention., Results: We included 1,613 consecutive PEG procedures in this study, of which 1,540 patients (95.5%) received some form of uninterrupted antithrombotic therapy. Of those patients, 535 (34.7%) were on aspirin, 256 (16.6%) on clopidogrel, and 119 (7.7%) on both aspirin and clopidogrel. Subcutaneous heparin was uninterrupted in 980 (63.6%), intravenous heparin in 34 (2.1%), warfarin in 168 (10.9%), and direct-acting oral anticoagulation in 82 (5.3%) patients who overlapped on multiple drugs. We observed 6 significant bleeding events in the entire cohort (0.39%), and all were in subcutaneous heparin groups either alone or in combination with aspirin. No clinically significant bleeding was noted in patients on uninterrupted aspirin, warfarin, clopidogrel, or direct-acting oral anticoagulation groups. Only 5 patients (0.31%) had PEG-related mortality., Discussion: The risk of significant bleeding associated with the PEG placement was minimal in patients on uninterrupted periprocedural antithrombotic therapy., (Copyright © 2021 by The American College of Gastroenterology.)

- Abstract
Background and Aim: Endoscopic gastrointestinal anastomosis using lumen-apposing metal stents (EGAL) is a new technique that is used as an alternative method to bypass benign or malignant strictures. Endoscopists take advantage of 2 bowel loops that are close to each other and place a stent between the lumen of these 2 bowel loops. The authors performed this systematic review and meta-analysis to evaluate the efficacy and safety of this rising procedure., Methods: Electronic database searches were conducted for full eligible articles that were published from the inception to July 2019 using the EGAL procedure to bypass malignant or benign obstruction or to restore bowel integrity after a gastrointestinal altering surgery. The primary outcome of this meta-analysis was to assess efficacy through technical and clinical success. Secondary outcomes were to assess safety through adverse events and to assess the rate of stent maldeployment and the rate of reintervention during the study period., Results: Eight studies were eligible, providing data on 269 patients who underwent 271 EGAL procedures. The median age was 65 years (interquartile range: 63 to 66) with 46% male individuals. Out of 269 patients, 203 underwent EGALs because of malignant etiology and 66 underwent EGAL for benign etiology. The median duration of follow-up was 114 days (interquartile range: 78 to 121). Technical success rate was 94.1% [95% confidence interval (CI), 91.4%-96.9%]. Clinical success rate was 91.4% (95% CI, 88.1%-94.7%). Adverse events rate was 8.5% (95% CI, 4.7%-12.3%). Stent maldeployment rate was 9.5% (95% CI, 3.5%-15.4%) of the total performed EGALs and the reintervention rate was 6.0% (95% CI, 2.3%-9.8%)., Conclusion: EGAL procedure has high efficacy and a relatively safe profile and it can be performed in selected patients. Comparison between EGAL and other conventional therapies is difficult because of the lack of randomized trials., Competing Interests: N.T. has a conflict of interest for being a consultant for Boston-Scientific.

- Abstract
Background and study aims Peroral endoscopic myotomy (POEM) is increasingly being used as the preferred treatment option for achalasia. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of POEM versus pneumatic balloon dilation (PD). Methods We performed a comprehensive review of studies that reported clinical outcomes of POEM and PD for the treatment of achalasia. Measured outcomes included clinical success (improvement of symptoms based on a validated scale including an Eckardt score ≤ 3), adverse events, and post-treatment gastroesophageal reflux disease (GERD). Results Sixty-six studies (6268 patients) were included in the final analysis, of which 29 studies (2919 patients) reported on POEM and 33 studies (3050 patients) reported on PD and 4 studies (299 patients) compared POEM versus PD. Clinical success with POEM was superior to PD at 12, 24, and 36 months (92.9 %, vs 76.9 % P = 0.001; 90.6 % vs 74.8 %, P = 0.004; 88.4 % vs 72.2 %, P = 0.006, respectively). POEM was superior to PD in type I, II and III achalasia (92.7 % vs 61 %, P = 0.01; 92.3 % vs 80.3 %, P = 0.01; 92.3 %v 41.9 %, P = 0.01 respectively) Pooled OR of clinical success at 12 and 24 months were significantly higher with POEM (8.97; P = 0.001 & 5.64; P = 0.006). Pooled OR of GERD was significantly higher with POEM (by symptoms: 2.95, P = 0.02 and by endoscopic findings: 6.98, P = 0.001). Rates of esophageal perforation (0.3 % vs 0.6 %, P = 0.8) and significant bleeding (0.4 % vs 0.7 %, P = 0.56) were comparable between POEM and PD groups. Conclusions POEM is more efficacious than PD in the treatment of patients with achalasia during short-term and long-term follow-up, albeit with higher risk of abnormal esophageal acid exposure., Competing Interests: Competing interests Dr. Thosani is a consultant for Boston Scientific, Medtronic, Endogastric Solutions, and Pentax of America; a speaker for Abbvie, and receives royalties from UpToDate.

- Abstract
Background and Aims: The American Society for Gastrointestinal Endoscopy (ASGE) 2010 guidelines for suspected choledocholithiasis were recently updated by proposing more specific criteria for selection of high-risk patients to undergo direct ERCP while advocating the use of additional imaging studies for intermediate- and low-risk individuals. We aim to compare the performance and diagnostic accuracy of 2019 versus 2010 ASGE criteria for suspected choledocholithiasis., Methods: We performed a retrospective chart review of a prospectively maintained database (2013-2019) of over 10,000 ERCPs performed by 70 gastroenterologists in our 14-hospital system. We randomly selected 744 ERCPs in which the primary indication was suspected choledocholithiasis. Patients with a history of cholecystectomy or prior sphincterotomy were excluded. The same patient cohort was assigned as low, intermediate, or high risk according to the 2010 and 2019 guideline criteria. Overall accuracy of both guidelines was compared against the presence of stones and/or sludge on ERCP., Results: Of 744 patients who underwent ERCP, 544 patients (73.1%) had definite stones during ERCP and 696 patients (93.5%) had stones and/or sludge during ERCP. When classified according to the 2019 guidelines, fewer patients were high risk (274/744, 36.8%) compared with 2010 guidelines (449/744, 60.4%; P < .001). Within the high-risk group per both guidelines, definitive stone was found during ERCP more frequently in the 2019 guideline cohort (226/274, 82.5%) compared with the 2010 guideline cohort (342/449, 76.2%; P < .001). In our patient cohort, overall specificity of the 2010 guideline was 46.5%, which improved to 76.0% as per 2019 guideline criteria (P < .001). However, no significant change was noted for either positive predictive value or negative predictive value between 2019 and 2010 guidelines., Conclusions: The 2019 ASGE guidelines are more specific for detection of choledocholithiasis during ERCP when compared with the 2010 guidelines. However, a large number of patients are categorized as intermediate risk per 2019 guidelines and will require an additional confirmatory imaging study., (Copyright © 2021 American Society for Gastrointestinal Endoscopy.
