Endoscopy

BACKGROUND: Endoscopic full-thickness resection (EFTR) is an effective and safe technique for non-lifting colorectal lesions. Technical issues or failures with full-thickness resection device (FTRD) system are reported but there are no data about their details. The aim of our study was to quantify and classify FTRD technical failures. PATIENTS AND METHODS: We performed a retrospective study involving 17 Italian centres with experience in advanced resection techniques and OVESCO devices...

Background and study aim Extensive esophageal ESDs without preventive measures are at high risk of stricture. Oral steroids and local injection of triamcinolone acetonide have proven to be effective for prevention of esophageal stricture. This study aimed to assess the efficacy of a systematic steroid administration protocol for stricture prevention. Patients and methods A retrospective review of all esophageal ESDs at H.U.B Erasme Hospital (Brussels) between 2016 and 2022 was conducted. Injection of triamcinolone was performed for mucosal defects between 50% and 90% circumference...

BACKGROUND AND STUDY AIM: Computer-aided detection (CADe) has been developed to improve detection during colonoscopy. After initial reports of high efficacy, there has been an increasing recognition of variability in the effectiveness of CADe systems. The aim of this study was to evaluate a CADe system (PENTAX Medical, Tokyo, Japan) in a varied colonoscopy population. PATIENTS AND METHODS: A multicenter, randomized trial was conducted at 7 hospitals (both university and non-university) in Europe and Canada...

OBJECTIVES: Missed lesions are common during standard colonoscopy and are correlated with post-colonoscopy colorectal cancer (PCCRC). Contrast-enhanced technologies have recently been developed to improve polyp detection. Our aim was to evaluate the impact of linked color imaging (LCI) on the proximal adenoma miss rate (pAMR) in routine colonoscopy. DESIGN AND METHODS: This national multicenter tandem randomized trial compared the outcomes of standard colonoscopy with white light imaging (WLI) to colonoscopy with LCI (Fujifilm), for polyp detection in the right colon...

BACKGROUND AND AIMS: Disposable digital single-operator cholangioscopy (D-SOC) and direct peroral cholangioscopy (D-POC) using an ultraslim endoscope are established POC modalities for the diagnosis and treatment of various biliary diseases. We compared the usefulness of D-SOC and D-POC for the diagnosis of intraductal superficial lesions of the bile duct (ISL-Bs). METHODS: In total, 38 consecutive patients with suspected biliary diseases who underwent both D-SOC and D-POC were enrolled...

Background and Aim Surveillance of non-dysplastic Barrett's esophagus (BE) is recommended to identify progression to dysplasia; however, the most cost-effective strategy remains unclear. Mutation or aberrant expression of p53 has been associated with the development of dysplasia in BE. We sought to determine if surveillance intervals for BE could be stratified based on p53 expression. Methods A Markov model was developed for non-dysplastic BE. Patients with non-dysplastic BE (NDBE) underwent p53 immunohistochemistry (IHC) and those with abnormal p53 expression underwent surveillance endoscopy at 1 year, whilst patients with normal p53 expression underwent surveillance in 3 years...

INTRODUCTION: The ileocecal valve (ICV) is considered to be one of the most difficult locations for endoscopic submucosal dissection (ESD). The objective of this study was to evaluate the efficacy and safety of traction-assisted ESD in this situation. METHODS: All patients who underwent traction assisted ESD for an ICV lesion were identified from a prospective ESD database in three centers. The results were evaluated in terms of en bloc, R0 rate. Factors associated with R0 failure were explored...

1:  ESGE recommends cold snare polypectomy (CSP), to include a clear margin of normal tissue (1-2 mm) surrounding the polyp, for the removal of diminutive polyps (≤ 5 mm).Strong recommendation, high quality of evidence. 2:  ESGE recommends against the use of cold biopsy forceps excision because of its high rate of incomplete resection.Strong recommendation, moderate quality of evidence. 3:  ESGE recommends CSP, to include a clear margin of normal tissue (1-2 mm) surrounding the polyp, for the removal of small polyps (6-9 mm)...

BACKGROUND: Endoscopy-related musculoskeletal injuries (ERIs) are commonly reported but their exact prevalence and clinical impact remain obscure. We conducted a systematic review and meta-analysis of the current literature aiming to answer these questions. METHODS: The MEDLINE, EMBASE, and SCOPUS databases were searched for studies evaluating ERIs in gastroenterologists and surgeons. The co-primary outcome was the prevalence of ERIs (i.e. carpal tunnel syndrome, de Quervain's tenosynovitis, and hand numbness)...

INTRODUCTION: The environmental impact of endoscopy, including small-bowel capsule endoscopy (SBCE), has gained attention due to its contribution to the global carbon footprint. This study aimed to evaluate the greenhouse gas (GHG) emissions (kgCO2e) of SBCE, including devices life cycle and capsule journey. METHODS: SBCE devices (3 brands) were evaluated using life cycle assessment methodology (ISO 14040), including patient travelling, bowel preparation, capsule examination and video recording...

BACKGROUND AND STUDY AIMS: Recognition of T1 colorectal cancer (CRC) is difficult, with sensitivities of 35-60% in Western countries. We evaluated the real-life effects of the implementation of the OPTICAL model, a recently developed structured and validated prediction model, in Dutch community hospitals. PATIENTS AND METHODS: In this prospective multicenter study, 383 endoscopists from 40 hospitals were invited to follow an e-learning on the OPTICAL-model, to increase sensitivity for detecting T1CRC in non-pedunculated polyps...

BACKGROUND: The optimal treatment for malignant gastric outlet obstruction (GOO) remains uncertain. The aim of this systematic review was to comprehensively investigate the efficacy and safety of four palliative treatments for malignant GOO: gastrojejunostomy (GJ), endoscopic ultrasound-guided gastroenterostomy (EGE), stomach-partitioning gastrojejunostomy (PGJ), and endoscopic stenting (ES). METHODS: We searched the PubMed, Embase, Cochrane Library, Scopus, and Web of Science databases; ClinicalTrials...

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/m2 , or with a BMI of 27...

BACKGROUND AND STUDY AIMS: This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection for Barrett's neoplasia recurrence after radiofrequency ablation. PATIENTS AND METHODS: Data from patients at sixteen centers were collected for a multicentric retrospective study. Patients who underwent at least one RFA treatment for Barrett's esophagus and thereafter underwent further esophageal ESD for neoplasia recurrence were included. RESULTS: Data from 56 patients treated by salvage ESD performed between April 2014 and November 2022 were collected...
