Comments on the current status and future development of natural orifice transluminal endoscopic surgery

An innovative procedure of laparoscope combined with endoscopy for gastrointestinal stromal tumor resection and cholecystectomy: A case report and literature review

The present study reports a novel approach to laparoscopic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumor (GIST) resection and cholecystectomy, and conducts a review of the associated literature. The novel surgical procedure was performed on one patient who was diagnosed with a GIST and cholecystic polypus. The GIST was resected using an insulation-tipped diathermic electrosurgical knife under the guide of an endoscope. Subsequently, a cholecystectomy was performed by inserting two more 5-mm trocars and instruments transumbilically, guided using an endoscope. The tumor and the gallbladder were exteriorized using a peroral approach and the incision lining of the stomach was sutured laparoscopically. The procedure was successfully performed and the patient experienced no discomfort during the 5-year follow-up. In conclusion, the present study demonstrates that laparoscopic and endoscopic cooperative surgery is feasible and would be an ideal choice for invisible abdominal scar surgery, in particular for multi-visceral resection.

New NOTES Clinical Training and Program Development

Natural orifice translumenal endoscopic surgery (NOTES) is an intense area of research, and is arguably the most significant endoscopic innovation of this decade. Training for new NOTES is a relatively long, encompassing advanced endoscopy training, mastery of endoscopic dexterity within the narrow submucosal or "third space" with an in-depth understanding of the tissue planes. Proficiency with new closure and hemostatic devices is also essential. Few institutions worldwide can provide all the cognitive and technical elements essential to train new NOTES trainees. Trainees may need to spend time across several institutions to ensure safe and effective practice of new NOTES.
