Laparoscopic basic skills are best trained in the nonclinical setting. Box trainers and virtual-reality trainers have been shown to be useful in training laparoscopic skills. Certain nonsurgical skills may predict baseline skills in these trainers. This study tested the hypothesis that baseline scores could be predicted in inanimate box trainers and virtual-reality trainers by nonsurgical skills. ⋯ Nonsurgical skills do not predict baseline scores in either trainer. The gender differences in VR training need to be further explored.

Randomized Controlled Trial Comparative Study
Physiologic effects of pneumoperitoneum in adults with sickle cell disease undergoing laparoscopic cholecystectomy (a case control study).
Many studies have demonstrated the adverse consequences of pneumoperitoneum. However, few studies have examined the physiologic effects of pneumoperitoneum in adults with sickle cell disease (SCD) during laparoscopic cholecystectomy (LC). ⋯ This study proved the safety of LC in patients with SCD and cholelithiasis, and that they can tolerate the physiological effects of pneumoperitoneum as non-SCD adults.

Comparative Study
Construct validity testing of a laparoscopic surgery simulator (Lap Mentor): evaluation of surgical skill with a virtual laparoscopic training simulator.
Before surgical simulators can be implemented for assessment of surgical training, their construct validity should be assessed. ⋯ Performance parameters of the Lap-Mentor can be used to distinguish between subjects with varying laparoscopic experience.

Comparative Study
Ultrashort intracorporeally maneuverable cryoprobes for laparoscopic renal cryoablation in the porcine model.
To determine the feasibility and efficacy of laparoscopic renal cryosurgery using a novel ultrathin ultrashort intracorporeal cryoprobe in a porcine model. ⋯ Our novel cryoprobe can be used effectively and conveniently in laparoscopic renal cryosurgery. Considering the size of the cryogenic lesion, using a cluster of probes may be advisable.
