Multicenter StudyGastric injury secondary to button battery ingestions: a retrospective multicenter review.
Removal of gastric button batteries (BBs) remains controversial. Our aim was to better define the spectrum of injury and to characterize clinical factors associated with injury from retained gastric BBs. ⋯ In this study, swallowed BBs posed a risk of damage to the stomach, including a single case of impaction and perforation of the gastric wall. Clinicians may want to consider retrieval within 12 hours of ingestion of gastric BBs. Larger prospective studies to assess risk of injury are needed.

Randomized Controlled Trial Multicenter StudyEffect of individualized feedback on learning curves in EGD and colonoscopy: a cluster randomized controlled trial.
Gastroenterology fellowships need to ensure that trainees achieve competence in upper endoscopy (EGD) and colonoscopy. Because the impact of structured feedback remains unknown in endoscopy training, this study compared the effect of structured feedback with standard feedback on trainee learning curves for EGD and colonoscopy. ⋯ Quarterly feedback in the form of individualized learning curves did not affect learning curves for EGD and colonoscopy in a clinically meaningful manner. (Clinical trial registration number: NCT02891304.).

Randomized Controlled Trial Multicenter StudyHigh-flow nasal cannula oxygen therapy and hypoxia during gastroscopy with propofol sedation: a randomized multicenter clinical trial.
Hypoxia is one of the most frequent adverse events with sedated GI endoscopy and can lead to serious consequences. No modalities have been found previously to prevent hypoxia. High-flow nasal cannula (HFNC) supportive oxygen therapy provides heated and humidified oxygen up to 60 L/minute. Because of its ability to improve respiratory function and good tolerance, we aimed to evaluate the validity and safety of HFNC supportive oxygen therapy in preventing the incidence of hypoxia in patients undergoing gastroscopy with propofol sedation. ⋯ HFNC supportive oxygen therapy can prevent the incidence of hypoxia and severe hypoxia in patients in America Society of Anesthesiologists class I-II undergoing elective gastroscopy under propofol sedation, with minimal related adverse events and good tolerance. (Clinical trial registration number: NCT03332433.).

Randomized Controlled Trial Multicenter Study Comparative StudyImpact of the supine position versus left horizontal position on colonoscopy insertion: a 2-center, randomized controlled trial.
Colonoscopy insertion is painful for some patients and is 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 was to clarify this issue. ⋯ As an economical and convenient method, SP can reduce CIT, ease pain, and improve patients' acceptance of unsedated colonoscopy. (Clinical trial registration number: NCT03289442.).

Multicenter Study Observational StudyRelationship between the endoscopic withdrawal time and adenoma/polyp detection rate in individual colonic segments: a KASID multicenter study.
Appropriate colonoscopy withdrawal times for individual colonic segments are not well known. The relationship between withdrawal time and adenoma detection rate (ADR)/polyp detection rate (PDR) in individual colonic segments was examined in this study. ⋯ The PDR and ADR appeared to be significantly increased when the withdrawal time was ≥2 minutes in the right-sided colon segment, ≥4 minutes in the proximal colon, and ≥3 minutes in the left-sided colon segment compared with shorter withdrawal times.
