Randomized Controlled Trial Comparative Study
Postoperative pain after transvaginal cholecystectomy: single-center, double-blind, randomized controlled trial.
Natural orifice transluminal endoscopic surgery (NOTES) has the potential to reduce postoperative pain. We compared postoperative pain in the hybrid NOTES procedure transvaginal video-assisted cholecystectomy (TVC) with standard conventional laparoscopic cholecystectomy (CLC). ⋯ In this study, no significant difference in pain on days 1 and 2 postoperatively between the two methods was found. The safety profile of TVC is comparable to CLC, and TVC patients would generally recommend this procedure to other patients.

Randomized Controlled Trial Comparative Study
Simulation-based training for thoracoscopic lobectomy: a randomized controlled trial: virtual-reality versus black-box simulation.
Video-assisted thoracic surgery is gradually replacing conventional open thoracotomy as the method of choice for the treatment of early-stage non-small cell lung cancers, and thoracic surgical trainees must learn and master this technique. Simulation-based training could help trainees overcome the first part of the learning curve, but no virtual-reality simulators for thoracoscopy are commercially available. This study aimed to investigate whether training on a laparoscopic simulator enables trainees to perform a thoracoscopic lobectomy. ⋯ Simulation-based training and targeted instructions enabled the trainees to perform a simulated thoracoscopic lobectomy. Traditional black-box training was more effective than virtual-reality laparoscopy training. Thus, a dedicated simulator for thoracoscopy should be available before establishing systematic virtual-reality training programs for trainees in thoracic surgery.

Randomized Controlled Trial
Learning from visual force feedback in box trainers: tissue manipulation in laparoscopic surgery.
Currently, task time and errors are often used as performance parameters in laparoscopic training. Training with the focus on task time improvement alone results in fast, but possibly less controlled, instrument movements and therefore suboptimal tissue handling skills. ⋯ The learning curves and the posttest indicate that training with visual force feedback improves tissue handling skills with no negative effect on the task time and instrument motions. Conventional laparoscopic training with visual time feedback improves instrument motion and task time, but it does not improve tissue manipulation skills.
