Purpose: We review the literature and describe our technique for laparoendoscopic single-site orchidopexy using a glove port and rigid instruments. We assessed the feasibility and outcomes of this procedure. Materials and Methods: We retrospectively reviewed the case records of all children who had undergone laparoendoscopic single-site orchidopexy by use of a surgical glove port and conventional rigid instruments for a nonpalpable intraabdominal testis between January 2013 and September 2014. Results: Data from a total of 20 patients were collected. The patients' mean age was 18 months. All cases had a nonpalpable unilateral undescended testis. Fourteen patients (70%) had an undescended testis on the right side and six patients (30%) had an undescended testis on the left side. Seventeen patients underwent primary orchidopexy. Three patients underwent single-port laparoscopic Fowler-Stephens orchidopexy for the first and the second stage. Average operating time was 57 minutes (range, 40 to 80 minutes). No patient was lost to follow-up. At follow-up, 2 testes were found to have retracted out of the scrotum and these were successfully dealt with in a second operation. One testis was hypoplastic in the scrotal pouch. There were no signs of umbilical hernia. Conclusions: Single-port laparoscopic orchidopexy using a glove port and rigid instruments is technically feasible and safe for various nonpalpable intraabdominal testes. However, surgical experience and long-term follow-up are needed to confirm the superiority of this technique.

Purpose Assistive technology has allowed providing valuableassistance to people with special needs. Several studies havetargeted “smart” wheelchairs. However, these prototypes arenot yet commercialized, mainly for security reasons. Theobjective of this study is to ameliorate the control successrate and fulfill maximally the security constraint. Methods In this paper, we present a multi-levels data fusiontechnique. Three subsystems operate separately to find thenavigation command. These subsystems are based respectivelyon EEG signals, head position tracking and eye tracking. Their individual decisions are then fused to deliver the finalcommand to the wheelchair. Results The proposed technique achieves was able to reacha success rate equal to 94.4%. This rate represents animprovement of 7% compared to single source controltechniques. Conclusions The results of this study demonstrate the abilityof data fusion to improve the success rate and to avoidcritical situations such as total breakdown in case of sensorfailure.
