ABSTRACT

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based approach for the role of endoscopy in the management of chronic pancreatitis (CP). This document was developed using the Grading of Recommendations Assessment, Development and Evaluation framework. The guideline addresses effectiveness of endoscopic therapies for the management of pain in CP, including celiac plexus block, endoscopic management of pancreatic duct (PD) stones and strictures, and adverse events such as benign biliary strictures (BBSs) and pseudocysts. In patients with painful CP and an obstructed PD, the ASGE suggests surgical evaluation in patients without contraindication to surgery before initiation of endoscopic management. In patients who have contraindications to surgery or who prefer a less-invasive approach, the ASGE suggests an endoscopic approach as the initial treatment over surgery, if complete ductal clearance is likely. When a decision is made to proceed with a celiac plexus block, the ASGE suggests an EUS-guided approach over a percutaneous approach. The ASGE suggests indications for when to consider ERCP alone or with pancreatoscopy and extracorporeal shock wave lithotripsy alone or followed by ERCP for treating obstructing PD stones based on size, location, and radiopacity. For the initial management of PD strictures, the ASGE suggests using a single plastic stent of the largest caliber that is feasible. For symptomatic BBSs caused by CP, the ASGE suggests the use of covered metal stents over multiple plastic stents. For symptomatic pseudocysts, the ASGE suggests endoscopic therapy over surgery. This document clearly outlines the process, analyses, and decision processes used to reach the final recommendations and represents the official ASGE recommendations on the above topics.

ABSTRACT

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. 3: The role of EUS-directed transgastric ERCP (EDGE) versus laparoscopic-assisted ERCP and enteroscopy-assisted ERCP (E-ERCP) in resolving biliary obstruction in patients with Roux-en-Y gastric bypass (RYGB) anatomy. 4: The role of EUS-BD versus E-ERCP and PTBD in resolving biliary obstruction in patients with surgically altered anatomy other than RYGB. 5: The role of EUS-guided gallbladder drainage (EUS-GBD) versus percutaneous gallbladder drainage and endoscopic transpapillary transcystic gallbladder drainage in resolving acute cholecystitis in patients who are not candidates for cholecystectomy.

ABSTRACT

BACKGROUND AND AIMS: The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope suturing necessitates removal of the scope, placement of the device, and reinsertion. A single channel, single sequence, through-the-scope suturing device has been developed to improve this process. This study aims to describe the efficacy, feasibility, and safety of a through-the-scope suturing device for gastrointestinal defect closure. METHODS: This was a retrospective multicenter study involving 9 centers of consecutive adult patients who underwent suturing using the X-Tack Endoscopic HeliX Tacking System (Apollo Endosurgery). The primary outcomes were technical success and long-term clinical success. Secondary outcomes included adverse events, recurrence, and reintervention rates. RESULTS: In all, 56 patients (mean age 53.8, 33 women) were included. Suturing indications included fistula repair (n=22), leak repair (n=7), polypectomy defect closure (n=12), peroral endoscopic myotomy (POEM) site closure (n=7), perforation repair (n=6), and ulcers (n=2). Patients were followed at a mean duration of 74 days. Overall technical and long-term clinical success rates were 92.9% and 75%, respectively. Both technical and clinical success rates were 100% for polypectomies, POEM-site closures, and ulcers. Success rates were lower for the repair of fistulas (95.5% technical, 54.5% clinical), leaks (57.1%, 28.6%), and perforations (100%, 66.7%). No immediate adverse events were noted. CONCLUSION: This novel, through-the-scope endoscopic suturing system, is a safe and feasible method to repair defects that are ≤3Ā cm. The efficacy of this device may be better suited for superficial defects as opposed to full-thickness defects. Larger defects will need more sutures and probably a double closure technique to provide a reinforcement layer.

ABSTRACT

Acute cholecystitis (AC) is associated with significant morbidity and mortality. Minimally invasive laparoscopic cholecystectomy remains the gold standard of treatment. Therapeutic endoscopy for management of AC continues to emerge as a favorable alternative to percutaneous gallbladder drainage in patients with prohibitive operative risk. Endoscopic management of AC includes transpapillary and transmural stenting. When patient-specific factors prevent both surgical and endoscopic treatment, percutaneous cholecystostomy tube (PCT) placement is an option. Early studies show PCT to have worse outcomes when compared against all other described treatment options for the management of AC.

ABSTRACT

BACKGROUND AND AIMS: Accurately diagnosing malignant biliary strictures (MBSs) as benign or malignant remains challenging. It has been suggested that direct visualization and interpretation of cholangioscopy images provide greater accuracy for stricture classification than current sampling techniques (ie, brush cytology and forceps biopsy sampling) using ERCP. We aimed to develop a convolutional neural network (CNN) model capable of accurate stricture classification and real-time evaluation based solely on cholangioscopy image analysis. METHODS: Consecutive patients with cholangioscopy examinations from 2012 to 2021 were reviewed. A CNN was developed and tested using cholangioscopy images with direct expert annotations. The CNN was then applied to a multicenter, reserved test set of cholangioscopy videos. CNN performance was then directly compared with that of ERCP sampling techniques. Occlusion block heatmap analyses were used to evaluate and rank cholangioscopy features associated with MBSs. RESULTS: One hundred fifty-four patients with available cholangioscopy examinations were included in the study. The final image database comprised 2,388,439 still images. The CNN demonstrated good performance when tasked with mimicking expert annotations of high-quality malignant images (area under the receiver-operating characteristic curve, .941). Overall accuracy of CNN-based video analysis (.906) was significantly greater than that of brush cytology (.625, PĀ = .04) or forceps biopsy sampling (.609, PĀ = .03). Occlusion block heatmap analysis demonstrated that the most frequent image feature for an MBS was the presence of frond-like mucosa/papillary projections. CONCLUSIONS: This study demonstrates that a CNN developed using cholangioscopy data alone has greater accuracy for biliary stricture classification than traditional ERCP-based sampling techniques.

ABSTRACT

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. In patients with post-transplant biliary strictures, we suggest ERCP as the initial intervention and cSEMSs as the preferred stent. In patients with unclear diagnosis or intermediate probability of a stricture, we suggest MRCP as the diagnostic modality. We suggest that antibiotics should be administered during ERCP when biliary drainage cannot be assured.

We suggest that antibiotics should be administered during ERCP when biliary drainage cannot be ensured.

ABSTRACT

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy provides an evidence-based approach to strategies to prevent endoscopy-related injury (ERI) in GI endoscopists. It is accompanied by the article subtitled "Methodology and Review of Evidence," which provides a detailed account of the methodology used for the evidence review. This document was developed using the Grading of Recommendations Assessment, Development and Evaluation framework. The guideline estimates the rates, sites, and predictors of ERI. Additionally, it addresses the role of ergonomics training, microbreaks and macrobreaks, monitor and table positions, antifatigue mats, and use of ancillary devices in decreasing the risk of ERI. We recommend formal ergonomics education and neutral posture during the performance of endoscopy, achieved through adjustable monitor and optimal procedure table position, to reduce the risk of ERI. We suggest taking microbreaks and scheduled macrobreaks and using antifatigue mats during procedures to prevent ERI. We suggest the use of ancillary devices in those with risk factors predisposing them to ERI.

ABSTRACT

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. We suggest the use of cholangioscopic and EUS-guided biopsy sampling especially for patients who undergo nondiagnostic sampling, cholangioscopic biopsy sampling for nondistal strictures and EUS-guided biopsy sampling distal strictures or those with suspected spread to surrounding lymph nodes and other structures.

ABSTRACT

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. Using a systematic review and meta-analysis of each diagnostic modality, including fluoroscopic-guided biopsy sampling, brush cytology, cholangioscopy, and EUS-guided FNA or fine-needle biopsy sampling, the American Society for Gastrointestinal Endoscopy Standards of Practice Committee provides this guideline on modalities used to diagnose biliary strictures of undetermined etiology. This document summarizes the methods used in the GRADE analysis to make recommendations, whereas the accompanying article subtitled "Summary and Recommendations" contains a concise summary of our findings and final recommendations.
