Randomized Controlled Trial Comparative Study
Thoracic epidural analgesia facilitates the restoration of bowel function and dietary intake in patients undergoing laparoscopic colon resection using a traditional, nonaccelerated, perioperative care program.
This randomized trial compared thoracic epidural analgesia with patient-controlled analgesia (PCA) using morphine for laparoscopic colectomy in a traditional, nonaccelerated, perioperative care program. ⋯ When a traditional perioperative care program is used for laparoscopic colectomy, thoracic epidural analgesia is superior to PCA in accelerating the return of bowel function and dietary intake, while providing better pain relief.

Randomized Controlled Trial
The influence of different training schedules on the learning of psychomotor skills for endoscopic surgery.
Psychomotor skills for endoscopic surgery can be trained with virtual reality simulators. Distributed training is more effective than massed training, but it is unclear whether distributed training over several days is more effective than distributed training within 1 day. This study aimed to determine which of these two options is the most effective for training endoscopic psychomotor skills. ⋯ The distributed group trained over several days was faster, with the same number of errors and the same instrument path length used. Psychomotor skill training for endoscopic surgery distributed over several days is superior to training on 1 day.

Randomized Controlled Trial
The effect of escalating feedback on the acquisition of psychomotor skills for laparoscopy.
In the acquisition of new skills that are difficult to master, such as those required for laparoscopy, feedback is a crucial component of the learning experience. Optimally, feedback should accurately reflect the task performance to be improved and be proximal to the training experience. In surgery, however, feedback typically is in vivo. The development of virtual reality training systems currently offers new training options. This study investigated the effect of feedback type and quality on laparoscopic skills acquisition. ⋯ The type and quality of feedback during psychomotor skill acquisition for MIS have a large effect on the strength of skills generalization to a simple MIS task and should be given serious consideration in curriculum design for surgical training using simulation tasks.

Randomized Controlled Trial
Prospective randomized controlled trial of laparoscopic trainers for basic laparoscopic skills acquisition.
Laparoscopic surgery requires a different set of skills than traditional open surgery. The acquisition of basic laparoscopic skills may help novices when learning laparoscopic procedures. This study tested the hypothesis that the combination of virtual reality and box trainers leads to better basic laparoscopic skill acquisition than either method alone or no training. ⋯ Our data demonstrate that the combination of virtual reality training and inanimate box training leads to better laparoscopic skill acquisition than either training method alone or no training at all. Optimal preclinical laparoscopic training should incorporate both virtual reality trainers and inanimate box trainers.

Randomized Controlled Trial Comparative Study
Comparison of laparoscopic and open repair of incisional and primary ventral hernia: results of a prospective randomized study.
Incisional hernia is an important complication of abdominal surgery. Its repair has progressed from a primary suture repair to various mesh repairs and laparoscopic repair. Laparoscopic mesh repair is a promising alternative, and in the absence of consensus, needs prospective randomized controlled trials. ⋯ Laparoscopic repair of incisional and ventral hernias is superior to open mesh repair in terms of significantly less blood loss, fewer complications, shorter hospital stay, and excellent cosmetic outcome.
