Randomized Controlled Trial Comparative StudyEfficacy of computed virtual chromoendoscopy on colorectal cancer screening: a prospective, randomized, back-to-back trial of Fuji Intelligent Color Enhancement versus conventional colonoscopy to compare adenoma miss rates.
Colonoscopy is the criterion standard for screening of colorectal neoplasms. Nonetheless, a substantial miss rate with conventional, white-light colonoscopy (WL) remains a challenge. ⋯ FICE at screening colonoscopy did not improve the adenoma miss rate or detection rate compared with WL.

Randomized Controlled Trial Multicenter Study Comparative StudyTraining and transfer of colonoscopy skills: a multinational, randomized, blinded, controlled trial of simulator versus bedside training.
The Olympus colonoscopy simulator provides a high-fidelity training platform designed to develop knowledge and skills in colonoscopy. It has the potential to shorten the learning process to competency. ⋯ Performance of novices trained on the colonoscopy simulator matched the performance of those with standard patient-based colonoscopy training, and novices in the simulator group demonstrated superior technical skills on simulated cases. The simulator should be considered as a tool for developing knowledge and skills prior to clinical practice.

Randomized Controlled Trial Comparative StudySimulator training improves practical skills in therapeutic GI endoscopy: results from a randomized, blinded, controlled study.
Therapeutic endoscopic procedures are technically challenging and have higher complication rates than diagnostic procedures. Less-experienced practitioners are significantly more likely to have a complication, yet there is very limited evidence of the efficacy of training in such procedures. ⋯ Hands-on skills training significantly improved performance in 3 therapeutic modalities. Knowledge-based teaching alone did not have a measurable effect. These results strongly support the benefit of intensive hands-on, simulation-based courses for endoscopic skills training.

Randomized Controlled Trial Comparative StudyAdministration of olive oil followed by a low volume of polyethylene glycol-electrolyte lavage solution improves patient satisfaction with right-side colonic cleansing over administration of the conventional volume of polyethylene glycol-electrolyte lavage solution for colonoscopy preparation.
Proper bowel cleansing before colonoscopy is essential for satisfactory evaluation of the colon. The required consumption of a large volume of salty-tasting liquid, 4 L of polyethylene glycol-electrolyte lavage solution (PEG-ELS), is the primary limitation to achieving this goal. ⋯ Pretreatment with olive oil before administration of a low volume of PEG-ELS enhances both patient satisfaction and the quality of right-side colonic cleansing over the administration of the conventional volume of PEG-ELS for colonoscopy preparation. Although the magnesium hydroxide regimen (Prep 2) was the preferred regimen in this study, its colonic cleansing effectiveness was not as great as those of the other regimens. Based on our results, the olive oil regimen is recommended, especially for patients who are not able to consume large volumes of liquids, such as the elderly, and those who are suspected of having subtle right-side colonic lesions.

Randomized Controlled Trial Comparative StudyA prospective randomized trial of 1 versus 2 injections during EUS-guided celiac plexus block for chronic pancreatitis pain.
The efficacy of 1-injection versus a 2-injections method of EUS-guided celiac plexus block (EUS-CPB) in patients with chronic pancreatitis is not known. ⋯ There was no difference in duration of pain relief or onset of pain relief in subjects with chronic pancreatitis and pain when the same total amount of medication was delivered in 1 or 2 injections during a single EUS-CPB procedure. Both methods were safe.
