Comparative Study Controlled Clinical TrialBlinded nonrandomized comparative study of gastric examination with a magnetically guided capsule endoscope and standard videoendoscope.
Passive video capsule endoscopy is the criterion standard for small-bowel exploration but cannot be used for the large gastric cavity. We report the first blinded comparative clinical trial in humans comparing a magnetically guided capsule endoscope (MGCE) and a conventional high-definition gastroscope. ⋯ Diagnostic results were similar for the 2 methods. After some technical difficulties related to gastric expansion or presence of mucus had been overcome, this study opened a new field for noninvasive gastric examination in countries where high gastric cancer incidence demands a screening tool.

Randomized Controlled TrialStrategies for training in diagnostic upper endoscopy: a prospective, randomized trial.
Training simulators have been used for decades with success; however, a standardized educational strategy for diagnostic EGD is still lacking. ⋯ Structured simulator training supplementing clinical training in upper endoscopy appears to be superior to clinical training alone. Simulator training alone does not seem to be sufficient to improve endoscopic skills.

The impact of video recording colonoscopy on adenoma detection rates.
The adenoma detection rate (ADR) is a quality benchmark for colonoscopy, influenced by several factors including bowel preparation, withdrawal time, and withdrawal technique. ⋯ Video recording of colonoscopies is associated with a nonsignificant increase in the ADR and a significant increase in the hyperplastic polyp detection rate. There may be a benefit of video recording for endoscopists with low ADRs.

Multicenter StudyLong-term effect of Helicobacter pylori eradication on the development of metachronous gastric cancer after endoscopic resection of early gastric cancer.
A prospective, randomized trial proved that Helicobacter pylori eradication significantly reduces the incidence of metachronous gastric cancer during a 3-year follow-up. ⋯ H pylori eradication does not reduce the incidence of metachronous gastric cancer. H pylori eradication should be performed before the progression of gastric mucosal atrophy.

Early cholecystectomy and ERCP are associated with reduced readmissions for acute biliary pancreatitis: a nationwide, population-based study.
Cholecystectomy is recommended during hospitalizations for acute biliary pancreatitis (ABP). ⋯ Cholecystectomy and ERCP during the index admission were associated with reduced readmission rates for ABP, providing population-based evidence to support consensus guidelines that recommend early biliary intervention.
