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.
Results:
Completion times with NSP were longer for ring transfer (P = .025) and trended longer for disc cutting (P = .074). Disc cutting accuracy was lower with NSP versus TL (P = .008). NSP operative times for hysterectomy, pelvic and para-aortic node dissection were 22.3, 13.3, and 26 minutes, respectively, without complications. Fatigue and lack of integrated bipolar cautery were limitations of NSP.
Conclusion:
While application of NSP to gynecology appears feasible, lower performance when compared with TL underscores the need for caution when applying NSP to humans.

Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
