Abstract

Natural Orifice Transluminal Endoscopic Surgery (NOTES) is a novel therapeutic strategy. This procedure stands on the cutting edge of minimal invasive abdominal surgery that accesses the abdominal organ through natural orifices such as mouth, anus and vagina with performing gastrointestinal endoscopy. There are many animal experiments and clinical trials of NOTES along with the development of better instruments. We report here on 4 cases of transgastric endoscopic cholecystectomy in canine and porcine models, and these procedures were done through natural orifices with performing conventional endoscopy and using endoscopic devices and laparoscopic trocars.
