This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based approach for strategies to diagnose and manage GERD. This document was developed using the Grading of Recommendations Assessment, Development, and Evaluation framework and serves as an update to the 2014 ASGE guideline on the role of endoscopy in the management of GERD. This updated guideline addresses the indications for endoscopy in patients with GERD as well as in the emerging population of patients who develop GERD after sleeve gastrectomy or peroral endoscopic myotomy.

Article Synopsis
  • * It favors percutaneous endoscopic gastrostomy (PEG) over interventional radiology-guided options and recommends starting tube feeding within 4 hours post-procedure.
  • * Additionally, the guideline states that antiplatelet medications usually don’t need to be stopped before PEG, while anticoagulant management should involve a team discussion considering bleeding and cardiovascular risks.

Article Synopsis
  • This clinical practice guideline from the ASGE offers evidence-based recommendations for using endoscopy to diagnose and manage pancreatic masses, focusing on needle selection and sample processing.
  • It advises the use of fine-needle biopsy (FNB) needles, particularly 22-gauge over 25-gauge, and recommends fork-tip or Franseen needle types, while suggesting against routine rapid on-site evaluation (ROSE) for initial tissue acquisitions.
  • For managing biliary obstructions and pain in unresectable cases, it recommends self-expandable metal stents (SEMSs) over plastic stents, with covered SEMSs preferred when malignancy is confirmed, and celiac plexus neurolysis (CPN) for abdominal pain.

Background: Frailty has been identified as an independent predictor of mortality in the elderly. We investigated the effects of frailty status on in-hospital outcomes of acute colonic diverticulitis (ACD) in the elderly, using the Hospital Frailty Risk Score.

Methods: We used the National Inpatient Sample (NIS) databases from 2016-2020 to identify patients aged ≥75 years hospitalized with ACD.

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy provides an evidence-based approach for the role of therapeutic EUS in the management of biliary tract disorders. This guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation framework and addresses the following: 1: The role of EUS-guided biliary drainage (EUS-BD) versus percutaneous transhepatic biliary drainage (PTBD) in resolving biliary obstruction in patients after failed ERCP. 2: The role of EUS-guided hepaticogastrostomy versus EUS-guided choledochoduodenostomy in resolving distal malignant biliary obstruction after failed ERCP.

Article Synopsis
  • This study examines the most effective resection techniques for early gastric cancer (EGC) in patients who have previously undergone resection, comparing endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) against traditional surgery.
  • The analysis included 10 observational studies, showing that ESD had a significantly higher rate of complete resection compared to EMR, while there were no notable differences in outcomes between ESD and surgery.
  • The findings suggest that ESD or surgery is generally preferred over EMR for metachronous EGC due to EMR's higher risk of incomplete resection, with treatment choice depending on local expertise and patient preferences

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based summary and recommendations regarding the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. It is accompanied by the document subtitled "Methodology and Review of Evidence," which provides a detailed account of the methodology used for the evidence review. This guideline was developed using the Grading of Recommendations, Assessment, Development and Evaluation framework and specifically addresses the role of ESD versus EMR and/or surgery, where applicable, for the management of early esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC) and their corresponding precursor lesions.

This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a full description of the methodology used in the review of the evidence used to inform the final guidance outlined in the accompanying Summary and Recommendations document regarding the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. This guideline used the Grading of Recommendations, Assessment, Development and Evaluation framework and specifically addresses the role of ESD versus EMR and/or surgery, where applicable, for the management of early esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC) and their corresponding precursor lesions. For ESCC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >15 mm, whereas in patients with similar lesions ≤15 mm, the ASGE suggests either ESD or EMR.

Biliary strictures of undetermined etiology pose a diagnostic challenge for endoscopists. Despite advances in technology, diagnosing malignancy in biliary strictures often requires multiple procedures. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to rigorously review and synthesize the available literature on strategies used to diagnose undetermined biliary strictures.

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy provides an evidence-based approach for the diagnosis of malignancy in patients with biliary strictures of undetermined etiology. This document was developed using the Grading of Recommendations Assessment, Development and Evaluation framework and addresses the role of fluoroscopic-guided biopsy sampling, brush cytology, cholangioscopy, and EUS in the diagnosis of malignancy in patients with biliary strictures. In the endoscopic workup of these patients, we suggest the use of fluoroscopic-guided biopsy sampling in addition to brush cytology over brush cytology alone, especially for hilar strictures.

Background: Disorders of gut-brain interaction (DGBI) cause a substantial health burden. Herein we studied the prevalence and characteristics of DGBI and symptoms of bloating/distension in El Paso, Texas on the US-Mexico border, providing a unique opportunity to study the effects of acculturation.

Methods: Subjects from community centers completed the Rome IV questionnaire for DGBI, short acculturation scale for Hispanics questionnaire, and bloating/distention Pictograms.

Article Synopsis
  • The American Society for Gastrointestinal Endoscopy released a guideline for managing biliary strictures in liver transplant recipients based on solid evidence and recommendations.
  • It discusses various treatment options like ERCP versus percutaneous transhepatic biliary drainage, and compares self-expandable metal stents with multiple plastic stents for effectiveness in managing post-transplant strictures.
  • The guideline recommends using ERCP as the first treatment, cSEMSs for extrahepatic strictures, MRCP for diagnosing uncertain strictures, and suggests giving antibiotics during ERCP if proper biliary drainage can't be ensured.

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy provides an evidence-based approach for strategies to manage biliary strictures in liver transplant recipients. This document was developed using the Grading of Recommendations Assessment, Development and Evaluation framework. The guideline addresses the role of ERCP versus percutaneous transhepatic biliary drainage and covered self-expandable metal stents (cSEMSs) versus multiple plastic stents for therapy of strictures, use of MRCP for diagnosing post-transplant biliary strictures, and administration of antibiotics versus no antibiotics during ERCP.

Informed consent is the cornerstone of the ethical practice of procedures and treatments in medicine. The purpose of this document from the American Society for Gastrointestinal Endoscopy (ASGE) Standards of Practice Committee is to provide an update on best practice of the informed consent process and other issues around informed consent and shared decision-making for endoscopic procedures. The principles of informed consent are based on longstanding legal doctrine.
