Early experience in human hybrid transgastric and transvaginal endoscopic cholecystectomy

Background Abdominal procedures have been performed for a long time through the anterior abdominal wall. Since the first reports in the 1980s, laparoscopy has become the standard for cholecystectomy, with many advantages over open procedures. Now a natural-orifice approach to the peritoneal cavity may further reduce the invasiveness of surgery by either diminishing or avoiding abdominal incisions. Several orifice routes to the abdominal cavity have been described: transgastric, transvaginal, transvesical, and transcolonic. Although most experiences with the porcine model showed the possibility of these approaches, few surgeons reported experiences with humans. The authors present their complete early experience with transgastric (TG) and transvaginal (TV) cholecystectomies in human beings.
