Area of Science:

Bariatric Surgery
Minimally Invasive Procedures
Endoscopic Surgery

Background:

Laparoscopic sleeve gastrectomy is a popular bariatric procedure for morbid obesity.
Postoperative follow-up for this procedure is currently limited to five years.
Natural orifice transluminal endoscopic surgery (NOTES) is an emerging field transitioning from animal to human trials.

Purpose of the Study:

To describe the first human application of a hybrid natural orifice transluminal endoscopic surgery (NOTES) transvaginal sleeve gastrectomy.
To report the short-term outcomes and complications of this novel bariatric procedure.

Main Methods:

A hybrid natural orifice transluminal endoscopic surgery (NOTES) approach was utilized.
The vagina served as the natural orifice for the sleeve gastrectomy procedure.
