This document discusses the history and development of natural orifice transluminal endoscopic surgery (NOTES). It describes early developments in the 18th century using colpotomy and ventroscopy. In the 1930s, techniques like colpolaparoscopy were introduced using rigid instruments through the vagina. It then outlines continued developments using both rigid and flexible instruments through the vagina and cul-de-sac for procedures like cholecystectomy, appendectomy, and notes how this approach has been adopted worldwide.
