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.

Comparative StudyOn-demand endoscopic CO2 insufflation with feedback pressure regulation during natural orifice transluminal endoscopic surgery (NOTES) peritoneoscopy induces minimal hemodynamic and respiratory changes.
Endoscopic insufflation has been associated with marked increase in intra-abdominal pressure (IAP) and hemodynamic and respiratory changes during transgastric surgery. ⋯ On-demand endoscopic insufflation of CO(2) with feedback pressure regulation can minimize the risk of hemodynamic and respiratory compromise caused by acute changes in IAP.

Randomized Controlled Trial Comparative StudyInspection on instrument insertion during colonoscopy: a randomized controlled trial.
Polyps seen and not removed during colonoscope insertion are sometimes unable to be found during withdrawal. ⋯ Inspection during colonoscope insertion offered no additional benefit compared with an equivalent period of inspection performed entirely during withdrawal. These results do not support an additional role for routine inspection during colonoscope insertion.
