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.

Randomized Controlled Trial Multicenter StudyParticipation by experienced endoscopy nurses increases the detection rate of colon polyps during a screening colonoscopy: a multicenter, prospective, randomized study.
No reported prospective, randomized study has evaluated the impact of an endoscopy nurse participating as a second observer during colonoscopy. ⋯ Experienced endoscopy nurse participation increased the PDR and ADR during screening colonoscopy. However, the benefit of participation by experienced nurses appears to be exclusively with inexperienced colonoscopists.

Randomized Controlled TrialTraining on an ex vivo animal model improves endoscopic skills: a randomized, single-blind study.
Animal models are used for training of different endoscopic procedures. Whether this really improves endoscopic skills remains controversial. ⋯ Hands-on training by using an animal ex vivo model improves endoscopic skills in both hemostasis and perforation closure. In clinical practice, the training improves the outcome of hemostatic procedures.

Randomized Controlled TrialFeasibility, safety, and effectiveness of transcranial direct current stimulation for decreasing post-ERCP pain: a randomized, sham-controlled, pilot study.
Emerging evidence shows that transcranial direct current stimulation (tDCS), a minimally invasive brain stimulation technique, has analgesic effects in chronic pain patients and in healthy volunteers with experimental pain. No studies have examined the analgesic effects of tDCS immediately after surgical/endoscopic procedures. Endoscopy investigating abdominal pain, especially ERCP, can cause significant postprocedural pain. ⋯ In this pilot study, tDCS appears to be safe, has minimal side effects, and may reduce postprocedural analgesia requirements and subjective pain ratings. Future studies appear warranted.

Randomized Controlled Trial Comparative StudySingle-balloon versus double-balloon endoscopy for achieving total enteroscopy: a randomized, controlled trial.
Balloon endoscopy has been accepted as an effective tool for examining the small intestine. Two types of balloon endoscopy, single and double, are commercially available. The difference in performance between these 2 types of balloon endoscopy has not yet been elucidated. ⋯ Total enteroscopy is more easily performed with DBE than with SBE.
