Randomized Controlled Trial
Epidural analgesia diminished pain but did not otherwise improve enhanced recovery after laparoscopic sigmoidectomy: a prospective randomized study.
The primary hypothesis for this study was that epidural analgesia reduces the use of opioids and thus advances bowel function and oral intake and shortens hospital stay after laparoscopic sigmoidectomy performed according to principles of enhanced recovery after surgery. ⋯ Epidural analgesia significantly alleviates pain, reducing the need for opioids during the first 48 h after laparoscopic sigmoidectomy. However, epidural analgesia does not alter postoperative oral intake, mobilization, or length of hospital stay.

Randomized Controlled Trial
Validated robotic laparoscopic surgical training in a virtual-reality environment.
A robotic virtual-reality (VR) simulator has been developed to improve robot-assisted training for laparoscopic surgery and to enhance surgical performance in laparoscopic skills. The simulated VR training environment provides an effective approach to evaluate and improve surgical performance. This study presents our findings of the VR training environment for robotic laparoscopy. ⋯ Our data shows that the VR environment adequately simulated the BC task. The significant differences found for the NP task may be attributed to an oversimplification in the VR environment. However, they do point to the need for improvements in the complexity of our VR simulation. Further research work is needed to develop effective and reliable VR environments for robotic laparoscopic training.
