RESUMEN
BACKGROUND AND PURPOSE: Prior research has demonstrated that counterintuitive laparoscopic surgical skills are enhanced by experience with video games. A similar relation with robotic surgical skills has not been tested. The purpose of this study was to determine whether prior video-game experience enhances the acquisition of robotic surgical skills. SUBJECTS AND METHODS: A series of 242 preclinical medical students completed a self-reported video-game questionnaire detailing the frequency, duration, and peak playing time. The 10 students with the highest and lowest video-game exposure completed a follow-up questionnaire further quantifying video game, sports, musical instrument, and craft and hobby exposure. Each subject viewed a training video demonstrating the use of the da Vinci surgical robot in tying knots, followed by 3 minutes of proctored practice time. Subjects then tied knots for 5 minutes while an independent blinded observer recorded the number of knots tied, missed knots, frayed sutures, broken sutures, and mechanical errors. RESULTS: The mean playing time for the 10 game players was 15,136 total hours (range 5,840-30,000 hours). Video-game players tied fewer knots than nonplayers (5.8 v 9.0; P = 0.04). Subjects who had played sports for at least 4 years had fewer mechanical errors (P = 0.04), broke fewer sutures (P = 0.01), and committed fewer total errors (P = 0.01). Similarly, those playing musical instruments longer than 5 years missed fewer knots (P = 0.05). CONCLUSIONS: In the extremes of video-game experience tested in this study, game playing was inversely correlated with the ability to learn robotic suturing. This study suggests that advanced surgical skills such as robotic suturing may be learned more quickly by athletes and musicians. Prior extensive video-game exposure had a negative impact on robotic performance.

The impact of hand-assisted laparoscopic donor nephrectomy on kidney allograft function, perioperative complications, and organ supply was evaluated by retrospective analysis of 41 hand-assisted laparoscopic donor nephrectomy patients and their recipients between January and October 2003. Serum creatinine at discharge, length of stay, estimated blood loss, operative time, and perioperative complications were analyzed. The mean values for laparoscopic donors and their recipients were 1.2 +/- 0.3 and 1.3 +/- 0.8 mg/dL for creatinine, 3.3 +/- 0.8 and 6.7 +/- 3 days for length of stay, and 110.4 +/- 76.9 and 111.6 +/- 56 mL for estimated blood loss, respectively. No major complications occurred in the laparoscopic donors. The number of living kidney donors increased by 94% compared to the mean of the previous 4 years following implementation of the laparoscopic program. Hand-assisted laparoscopic donor nephrectomy is safe, results in excellent allograft function, and significantly increases donation.

The most common cause of vesicovaginal fistula (VVF) in North America is injury to the bladder during a hysterectomy. In underdeveloped countries, childbirth is the leading etiology of these fistulae. Although the diagnosis of a VVF usually can be readily made in an outpatient setting, care must be exercised not to overlook a second fistula or concomitant ureteral injury. The timing of repair of the VVF is dependent on its etiology, comorbidities, and the anticipated approach for repair of the fistula. The transvaginal approach is more amenable to an early repair, is less invasive, and is accompanied by a 90% or higher success rate. Fistulae related to pelvic irradiation and recurrent fistulae are complex and may require interposition of vascularized tissue for successful repair.
