BACKGROUND: Laparoendoscopic single-site surgery (LESS) allows better cosmesis and decreased pain when compared with traditional laparoscopy (TL). Instrument crowding and diminished triangulation are limitations. This study evaluates a novel single-port surgical platform (NSP) designed to facilitate the transition from TL to LESS (TransEnterix SPIDER, Durham, NC). METHODS: NSP and TL were compared using standardized dry lab tasks. Feasibility of NSP in gynecology was assessed using the porcine model...

PURPOSE: The goal of this report is to describe our initial clinical experience performing a simple nephrectomy with the SPIDER (Single Port Instrument Delivery Extended Reach) laparoendoscopic single-site (LESS) surgical system. PATIENT AND METHODS: One patient with a nonfunctioning kidney secondary to a ureteropelvic junction obstruction underwent a simple nephrectomy through a single incision performed using the SPIDER surgical system. We assessed the technical feasibility, efficiency, and perioperative outcomes...

This case study describes our initial laboratory experience using the SPIDER surgical system (TransEnterix, Morrisville, NC, USA) for laparoendoscopic single-site surgery (LESS) urologic procedures and reports its first clinical application. The SPIDER system was tested in a laboratory setting and used for a clinical case of renal cyst decortication. Three tasks were performed during the dry lab session, and different urologic procedures were conducted in a porcine model. The time to complete the tasks and penalties were registered during the dry lab session...

With the introduction of natural orifice translumenal endoscopic surgery (NOTES), there has been interest in the general surgery community for developing safe, scarless surgery. NOTES itself brought additional risks to GI surgery, and as such it has not achieved mainstream acceptance. Single site is considered by many surgeons as a bridge between traditional laparoscopic surgery and NOTES without the inherent risks of NOTES. However, initial single-site procedures using standard instrumentation are technically challenging due to the absence of instruments that facilitate triangulation, avoid conflicts between the instruments and the camera, maintain pneumoperitoneum, and reduce operative stress...

INTRODUCTION: Single-port or single-incision cholecystectomy with current rigid laparoscopic devices is limited by in-line visualization, restricting the ability to approach the surgical site with proper angles and instrumentation. A single-port access system with articulating arms and strong instrumentation should minimize these issues. The TransEnterix system may facilitate safe and straightforward single-port surgery. METHODS: The TransEnterix single-port surgery system was used in both survival and nonsurvival porcine laparoscopic cholecystectomies under animal use committee approval...
