Randomized Controlled Trial
Randomized double-blind placebo-controlled study of the efficacy of continuous infusion of local anesthetic to the diaphragm closure following laparoscopic hiatal hernia repair.
Laparoscopic repair of hiatal hernia can result in significant postoperative pain requiring use of narcotics and patient dissatisfaction. A catheter-based delivery method that has demonstrated effectiveness and safety in other laparoscopic and open procedures (ON-Q, I Flow Corporation) was used to deliver pain medicine. This randomized double-blind, placebo-controlled study evaluated the efficacy of continuous infusion of local anesthetic to the diaphragm closure post laparoscopic hiatal hernia repair. ⋯ This randomized double-blind, placebo-controlled trial showed no advantage in using the ON-Q pain pump in terms of providing measurable reduction of pain or concomitant narcotic or nausea medication use. Further studies are indicated to determine alternatives for reducing postoperative pain after laparoscopic hiatal hernia repair.

Randomized Controlled Trial Comparative Study
A head-to-head comparison between virtual reality and physical reality simulation training for basic skills acquisition.
This study aimed to investigate whether basic laparoscopic skills acquired with a virtual reality simulator (LapVR™) are transferable to a standard video trainer (VT) and vice versa. ⋯ Both modalities provided significant enhancement of the novices' performance. The skills learned on the LapVR™ are transferable to the VT and vice versa. However, training with one modality does not necessarily mean a performance equivalent to that achieved with the other modality.
