Natural-orifice Transgastric Endoscopic Peritoneoscopy in Humans: Initial Clinical Trial. Hazey JW et al. 2008;22:16-20 • To investigate the feasibility and develop needed techniques and technology for NOTES, the authors conducted a study performing transoral transgastric diagnostic peritoneoscopy. Ten patients underwent diagnostic laparoscopic evalution of a pancreatic mass, and the findings were recorded by anatomical abdominal quadrant. A second surgeon, blinded to the initial results then performed transgatric peritoneoscopy. Diagnostic findings between the two methods were compared, and the authors concluded that transgastric diagnostic peritoneoscopy is safe and feasible.
