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.

Randomized Controlled Trial Comparative StudyA prospective, randomized study of EUS-guided celiac plexus neurolysis for pancreatic cancer: one injection or two?
The technique of alcohol injection during EUS-guided celiac plexus neurolysis (CPN) in patients with pancreatic cancer-related pain has not been standardized. ⋯ There were no differences in onset or duration of pain relief when either 1 or 2 injections were used. There was no difference in safety or survival between the 2 groups.

Randomized Controlled Trial Comparative StudyNitrous oxide for analgesia in colonoscopy without sedation.
Colonoscopy is associated with pain and discomfort, and intravenous analgesics and sedatives are widely used. There are several disadvantages regarding this practice, including risk of complications, resources demanded, and amnesia after sedation. In spite of promising results in previous studies, nitrous oxide is rarely used at endoscopy centers around the world. ⋯ Nitrous oxide given intermittently is not an effective substitution for intravenous on-demand sedation and analgesics in the setting of colonoscopy without sedation.
