Randomized Controlled Trial Clinical Trial
Assessment of basic endoscopic performance using a virtual reality simulator.
The objective of this study was to evaluate the effect of supervised training using a state-of-the-art virtual reality (VR) genitourinary endoscopy simulator on the basic endoscopic skills of novice endoscopists. ⋯ Students trained on the VR simulator demonstrated statistically significant improvement on repeat testing, but the control group showed no improvement. Endourologic training using VR simulation facilitates performance of basic endourologic tasks and might translate into better performance in the operating room.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective randomized clinical trial comparing nitrous oxide and carbon dioxide pneumoperitoneum for laparoscopic surgery.
Recent publications demonstrating the safety and advantages of N2O for pneumoperitoneum (PP) prompted us to reconsider N2O as an agent for PP in general surgical laparoscopy. The purpose of this prospective, double-blind, randomized clinical trial was to determine whether N2O PP has any benefits over CO2 PP. ⋯ These results suggest that the use of N2O PP has sufficient advantages over CO2 that it should be considered as the standard agent for therapeutic PP.

Randomized Controlled Trial Clinical Trial
Gum chewing enhances early recovery from postoperative ileus after laparoscopic colectomy.
Postoperative ileus limits early hospital discharge for patients who have undergone laparoscopic procedures. Sham feeding has been reported to enhance bowel motility. Here, the effect of gum chewing is evaluated as a convenient method to enhance postoperative recovery from ileus after laparoscopic colectomy. ⋯ Gum chewing aids early recovery from postoperative ileus and is an inexpensive and physiologic method for stimulating bowel motility. Gum chewing should be added as an adjunct treatment in postoperative care because it might contribute to shorter hospital stays.

Randomized Controlled Trial Multicenter Study Clinical Trial
Fibrin sealant reduces the duration and amount of fluid drainage after axillary dissection: a randomized prospective clinical trial.
Patients who have axillary dissections during lumpectomy or modified radical mastectomy for breast carcinoma accumulate serosanguinous fluid, potentially resulting in a seroma. Currently accepted practice includes insertion of one or more drains for fluid evacuation. This multicenter, randomized, controlled, phase II study was undertaken to evaluate whether a virally inactivated, investigational fibrin sealant is safe and effective when used as a sealing agent to reduce the duration and volume of serosanguinous fluid drainage and to determine the dose response of this effect. ⋯ Application of fibrin sealant following axillary dissection at the time of lumpectomy or modified radical mastectomy can significantly decrease the duration and quantity of serosanguinous drainage. The viral safety of the product was also supported.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of pulmonary function and postoperative pain after laparoscopic versus open gastric bypass: a randomized trial.
Impairment of pulmonary function is common after upper abdominal operations. The purpose of this study was to compare postoperative pulmonary function and analgesic requirements in patients undergoing either laparoscopic or open Roux-en-Y gastric bypass (GBP). ⋯ Laparoscopic gastric bypass resulted in less postoperative suppression of pulmonary function, decreased pain, improved oxygenation, and less atelectasis than open gastric bypass.
