Randomized Controlled Trial Multicenter Study Comparative StudyPatient-controlled analgesia with inhaled methoxyflurane versus conventional endoscopist-provided sedation for colonoscopy: a randomized multicenter trial.
Inhaled methoxyflurane (Penthrox, Medical Device International, Melbourne, Australia) has been used extensively in Australasia (Australia and New Zealand) to manage trauma-related pain. The aim is to evaluate the efficacy, safety, and outcome of Penthrox for colonoscopy. ⋯ Patient-controlled analgesia with inhaled Penthrox is feasible and as effective as conventional sedation for colonoscopy with shorter recovery time, is not associated with respiratory depression, and does not influence the procedural success and polyp detection.

Randomized Controlled TrialWater exchange enhanced cecal intubation in potentially difficult colonoscopy. Unsedated patients with prior abdominal or pelvic surgery: a prospective, randomized, controlled trial.
Colonoscopy is widely used for management of colorectal diseases. A history of abdominal or pelvic surgery is a well-recognized factor associated with difficult colonoscopy. Although water exchange colonoscopy (WEC) was effective in small groups of male U.S. veterans with such a history, its application in other cultural settings is uncertain. ⋯ NCT01485133.).

Randomized Controlled Trial Comparative StudyProspective, randomized, single-center trial comparing double-balloon enteroscopy and spiral enteroscopy in patients with suspected small-bowel disorders.
Double-balloon enteroscopy (DBE) is an established method in diagnostic and therapeutic small-bowel enteroscopy. ⋯ SE does not represent an alternative to DBE with regard to the depth of insertion or the rate of complete enteroscopies achieved. However, SE is advantageous in that it involves significantly shorter examination times. Further technical improvements will be necessary before SE can compete with DBE for complete enteroscopies.

Randomized Controlled Trial Comparative StudyWarm water infusion during sedated colonoscopy does not decrease amount of sedation medication used.
Water infusion versus air insufflation during colonoscope insertion has been suggested to reduce patient discomfort and decrease sedation medication requirements. Warm water is thought to further facilitate colonoscopy perhaps by decreasing colon spasm. ⋯ Water does not need to be warmed before infusion in patients undergoing sedated colonoscopies.

Randomized Controlled Trial Comparative StudyRandomized trial comparing the 22-gauge aspiration and 22-gauge biopsy needles for EUS-guided sampling of solid pancreatic mass lesions.
To overcome limitations of cytology, biopsy needles have been developed to procure histologic samples during EUS. ⋯ Diagnostic sufficiency, technical performance, and safety profiles of FNA and FNB needles are comparable. There was no significant difference in yield or quality of the histologic core between the 2 needle types.
