Endoscopic submucosal dissection for the treatment of gastrointestinal neoplasia in a tertiary-care center in Mexico.

Objective: The aim of this study was to evaluate the experience of using endoscopic submucosal dissection (ESD), a technique considered as first-line of treatment, for the management of early neoplastic lesions (ENL), and subepithelial lesions (SEL) < 4 cms in size, in a tertiary-care, high-volume medical center in Mexico.

Method: Patients > 18 years-old, candidates to ESD with ENL and SMT, between January 2008 and October 2022 were included.

Results: ESD was performed in 246 patients (137 ENL and 109 SMT), 52.

Predictive value of patency capsule and magnetic resonance enterography for capsule endoscopy retention in patients with established Crohn's disease.

Introduction: retention is the most common adverse event of the small bowel capsule endoscopy procedure. Patency capsule (Medtronic, Dublin, Ireland) and magnetic resonance enterography are two diagnostic methods that can prevent small bowel capsule endoscopy retention. The aim of this study was to evaluate the predictive value of these two diagnostic methods.

Assessment of the Role of a Second Evaluation of Capsule Endoscopy Recordings to Improve Diagnostic Yield and Patient Management.

Introduction: The diagnostic yield (DY) of small-bowel capsule endoscopy (SBCE) varies considerably according to its indication. Some strategies have been used to increase DY with varying results. The intention of this study was to identify whether evaluation of the SBCE recordings by a second reviewer can increase DY and change patient management.

Safety and efficacy of biodegradable stents in octogenarian patients with esophageal achalasia.

 Treatment of octogenarian patients with achalasia with conventional treatments is effective but with compromised safety. Biodegradable stents (BS) are promising. We aimed to evaluate their safety, efficacy and clinical outcomes at early, mid and long-term in this population.

Can topical epinephrine application to the papilla prevent pancreatitis after endoscopic retrograde cholangiopancreatography? Results from a double blind, multicentre, placebo controlled, randomised clinical trial.

Background And Study Aims: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a complication associated with important morbidity, occasional mortality and high costs. Preventive strategies are suboptimal as PEP continues to affect 4% to 9% of patients. Spraying epinephrine on the papilla may decrease oedema and prevent PEP.

Feasibility of using an led-probe in third-space endoscopy: a clinical study.

Background: Third-space endoscopy is a novel, safe, and effective method for treating different gastrointestinal conditions. However, several failed endoscopic procedures are attributed to incomplete myotomy. Lighting devices are used to prevent organic injuries.

Clinical feasibility of a new antireflux ablation therapy on gastroesophageal reflux disease (with video).

Backgrounds And Aims: New mucosal resective and ablative endoscopic procedures based on gastric cardiac remodeling to prevent reflux have appeared. We aimed to evaluate the feasibility of a new ablative technique named antireflux ablation therapy (ARAT) for control of GERD in patients without hiatal hernia.

Methods: Patients with proton pump inhibitor (PPI)-refractory GERD without hiatal hernia underwent ARAT between January 2016 and October 2019.

Predictors for finding lesions in the small bowel by enteroscopy after a positive capsule endoscopy.

Introduction: studies have examined the agreement between capsule endoscopy and double-balloon enteroscopy, with varying results. The aim of this study was to identify factors that predict the visualization of lesions in the small bowel by double-balloon enteroscopy after a positive capsule endoscopy.

Methods: a retrospective, observational and comparative study was performed that evaluated patients that underwent double-balloon enteroscopy after a positive capsule endoscopy, between January 2017 and August 2019.

Conventional clips vs over-the-scope-clips for the closure of the entry site in POEM and G-POEM procedures.

Background: new alternatives for entry site closure (ESC) in per-oral endoscopy myotomy (POEM) and gastric peroral endoscopy myotomy (G-POEM) have appeared.

Objective: to compare the over-the-scope-clip (OTSC®) and conventional clips (CC) for ESC in POEM and G-POEM.

Material And Methods: a retrospective review of a prospective POEM and G-POEM database was performed between January 2015 and August 2019.
