Experimental trial of transvaginal cholecystectomy: an ex vivo analysis of the learning process for a novel single-port technique

Background Interest in natural orifice transluminal endoscopic surgery (NOTES) has expanded, and the first experiences with patients using different techniques have been reported. However, no work has addressed the learning process or the limitations of the procedures. The relation between inexperience and complications became a major concern after the introduction of laparoscopic surgery. This study investigates the learning process for a new technique using specially designed instruments in an ex vivo model before clinical application.
