title: Natural Orifice Translumenal Endoscopic Surgery: Review of Its Applications in Bariatric Procedures.
abstract: This review aims to summarise clinical applications of natural orifice translumenal endoscopic surgery (NOTES) in bariatric surgery. A review of data, until December 2014, was carried out regarding techniques and outcomes of bariatric NOTES procedures. Nine publications were included in the final analysis, with another six papers describing endolumenal procedures included for comparison. All NOTES studies adopted a hybrid procedure. Hybrid NOTES sleeve gastrectomy (hNSG) was described in four humans and two porcine studies. In humans, six subjects (23.1%) were converted to conventional laparoscopic methods, and one postoperative complication (3.8%) was reported. Mean excess weight loss was 46.6% (range 35.2-58.9). Transvaginal-assisted sleeve gastrectomy appears feasible and safe when performed by appropriately trained professionals. However, improvements must be made to overcome current technical limitations.
