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.

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.

Background And Aims: Gastric peroral endoscopic myotomy (G-POEM) is used for refractory gastroparesis (RG) with good early-term but variable mid- and long-term outcomes. Limited data exist about candidates and long-term clinical and predictive factors. Our aim was to evaluate the 4-year follow-up efficacy and predictive factors in patients with RG.

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.

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.

Introduction: the aim of this study was to determine the risk factors for rebleeding following device-assisted enteroscopy therapy of small bowel vascular lesions.

Methods: this is a systematic review and meta-analysis. A literature search was performed from January 2003 to October 2019.

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.

Introduction: carbon dioxide (CO2) insufflation during enteroscopy reduces procedure time and subsequent symptoms and increases the insertion depth compared with room air. In colonoscopy, the water-exchange (WE) technique is associated with less pain compared with CO2 insufflation. The WE technique is not well studied in enteroscopy.

Article Synopsis
  • The study aimed to determine how common small bowel polyps and tumors are in patients with acromegaly compared to those without the condition.
  • It included 183 patients, with 61 having acromegaly and 122 without, and utilized capsule endoscopy to detect polyps and tumors.
  • The findings showed that 9.8% of acromegaly patients had polyps, significantly higher than the 2.5% in non-acromegaly patients, suggesting that acromegaly could be linked to a higher risk of small bowel polyps.

Background: Peroral endoscopic myotomy (POEM) is a recognized technique for patients with achalasia. We aimed to evaluate the feasibility of using a small-caliber endoscope (thin-POEM) to perform POEM in patients with achalasia.

Methods: Naïve or previously treated patients were included between February 2016 and April 2018.

Background: Esophageal achalasia is a primary motor disorder of the esophagus characterized by impair relaxation of the lower esophageal sphincter and absent of esophageal peristalsis. Per-oral endoscopic myotomy is an alternative treatment to surgical Heller myotomy in patients over 65 years old. The aim of this paper was to describe the results of peroral endoscopic myotomy (POEM) or the treatment of achalasia in geriatric patients.

Background And Study Aim: Per oral endoscopic myotomy (POEM) is a complex technique used in achalasia. Preclinical training is essential but little is known about the number of procedures needed. The aim of this study was to determine the number of procedures required to master POEM in an animal model.
