BACKGROUND AND AIMS: Minimum EUS and ERCP volumes that should be offered per trainee in "high quality" advanced endoscopy training programs (AETPs) are not established. We aimed to define the number of procedures required by an "average" advanced endoscopy trainee (AET) to achieve competence in technical and cognitive EUS and ERCP tasks to help structure AETPs. METHODS: ASGE-recognized AETPs were invited to participate; AETs were graded on every fifth EUS and ERCP examination using a validated tool...

BACKGROUND AND AIMS: It is standard of care to perform ileocolonoscopy within a year of ileocolonic resection for Crohn's disease (CD) and to guide management decisions based on the Rutgeert score (RS). The modified RS subdivides i2 into lesions confined to the anastomosis (i2a) or >5 aphthous lesions in the neoterminal ileum (i2b). There is uncertainty, however, if i2a lesions incur an increased risk of disease recurrence. The primary aim of this study was to compare the rates of endoscopic progression between i2a and i2b when compared with i0-i1...

BACKGROUND AND AIMS: Colonic endoscopic submucosal dissection (ESD) is more difficult than rectal ESD because of poor maneuverability of the endoscope due to physiological flexion, peristalsis and respiratory movements. The aim of this study is to assess the usefulness of the pocket-creation method (PCM) for colonic ESD compared with the conventional method (CM) regardless of lesion shape or location. METHODS: A total of 887 colorectal lesions were treated by ESD...

BACKGROUND AND AIMS: Endoscopic stricturotomy is a novel technique in the treatment of anastomotic strictures in Crohn's disease (CD). The aim of this study was to compare the outcome of patients with ileocolonic anastomotic stricture treated with endoscopic stricturotomy (ESt) versus ileocolonic resection (ICR). METHODS: This historical cohort study included consecutive CD patients with ileocolonic anastomotic stricture treated with ESt or ICR from 2010 to 2017...

BACKGROUND AND AIMS: A fecal immunochemical test (FIT) is often repeated annually, even after a recent colonoscopy. However, there are no published data on the proper approach to FIT-positive patients after a recent colonoscopy. We compared colorectal cancer (CRC) and advanced colorectal neoplasia (ACRN) prevalence based on the interval since the last colonoscopy. METHODS: We reviewed asymptomatic screenees aged ≥50 years who underwent FIT and colonoscopy. RESULTS: Of 2,228 FIT-positive participants, the number who had a colonoscopy less than 3 years prior (Group 1), 3 to 10 years prior (Group 2), and >10 years prior or no colonoscopy (Group 3) was 514, 427, and 1,287, respectively...

BACKGROUND AND AIMS: Self-expanding metal stents (SEMSs) when deployed across the gastroesophageal junction (GEJ) can lead to reflux with risks of aspiration. A SEMS with a tricuspid anti-reflux valve (SEMS-V) was designed to address this issue. The aim of this study was to evaluate the efficacy and safety of this stent. METHODS: A phase 3, multicenter, prospective, noninferiority, randomized, controlled trial was conducted on patients with malignant dysphagia requiring SEMSs to be placed across the GEJ...

BACKGROUND AND AIMS: Cold snare polypectomy (CSP) and jumbo forceps polypectomy (JFP) have been shown to be effective for removing diminutive colorectal polyps (DCPs) (≤5 mm). However, no study has compared complete resection rates between CSP and JFP for DCPs. The aim of this study was to compare the efficacy and safety of JFP to CSP for the removal of DCPs. METHODS: This was a prospective randomized controlled trial from 2 tertiary-care referral centers. A total of 1003 patients were screened, and 169 patients with 196 DCPs were enrolled...

BACKGROUND AND AIMS: Colonoscopy insertion is painful for some patients, constituting one of the main barriers to screening colonoscopy. Few studies have assessed the impact of the supine position (SP) on colonoscopy insertion, especially for unsedated patients. The aim of this randomized controlled trial (RCT) is to clarify this issue. METHODS: Unsedated patients were randomized to SP or left horizontal position (LHP) as the starting position of colonoscopy insertion...

BACKGROUND AND AIMS: The gastric premalignant conditions (GPCs) diagnosis rely on endoscopy with mucosal sampling. We hypothesized that the endoscopists' biopsy rate (EBR) might constitute a quality indicator for esophagogastroduodenoscopy (EGD) and we have analyzed its association with GPC detection and the rate of missed gastric cancers (GCs). METHODS: We analyzed EGD databases from 2 high-volume outpatient units. EBR values, defined as proportion of EGDs with ≥1 biopsy to all examinations, were calculated for each endoscopist in Unit A (derivation cohort) and divided by the quartile values into 4 groups...

BACKGROUND AND AIMS: The cecal intubation rate (CIR) is a widely accepted key performance indicator (KPI) in colonoscopy but lacks a universal calculation method. We aimed to assess whether differences in CIR calculation methods could impact on perceived trainee outcomes. METHODS: A systematic review of CIR calculation methods was conducted on major societal guidelines (United Kingdom, European Society of Gastrointestinal Endoscopy [ESGE] and American Society for Gastrointestinal Endoscopy [ASGE]) and trainee-inclusive studies...

BACKGROUND & AIMS: Current international guidelines recommend endoscopic resection for T1 colorectal cancer (CRC) with histological low-risk features and oncologic resection for those at high-risk of lymphatic metastasis. Exact risk stratification is therefore crucial to avoid under- as well as over-treatment. Endoscopic full-thickness resection (EFTR) has shown to be effective for treatment of nonlifting benign lesions. In this multicenter, retrospective study we aimed to evaluate efficacy, safety and clinical value of EFTR for early colorectal cancer...

BACKGROUND AND AIMS: Duodenoscopes have been implicated in the transmission of multidrug-resistant organisms (MDROs). Echoendoscopes could also potentially transmit infection. The aim of this study was to assess the effectiveness of standard high-level disinfection (sHLD) for radial and linear echoendoscopes and to compare it with that of duodenoscopes. METHODS: We performed a prospective single-center study sampling echoendoscopes immediately before use, from the working channel (radial and linear echoendoscope) and the transducer (radial echoendoscope) or elevator mechanism and transducer (linear echoendoscope)...

BACKGROUND AND AIMS: Gastric per-oral endoscopic pyloromyotomy (GPOEM) is a novel procedure with promising potential for the treatment of gastroparesis but with limited data regarding predictors of clinical response. This study aims to evaluate the safety and efficacy of the procedure and explore the impact of duration and etiology (diabetic vs nondiabetic) of gastroparesis on clinical outcome as measured by the Gastroparesis Cardinal Symptom Index (GCSI). METHODS: A single-center retrospective longitudinal study at a tertiary care hospital was performed over an 18-month period...
