Abstract:
Objective The optimal access for natural orifice transluminal endoscopic surgery is still uncertain .This study was designed to compare the practicability and maneuverability of transgastric ,transunmbilical ,and transrectal approach in abdominal surgery in a canine model .Methods Three dogs were used in this research .Three approach :trangastric ,transunmbilical and tran-srectal approach were carried out for abdominal exploration ,liver biopsy ,bladder biopsy and an attempted cholecystectomy .The ma-neuverability ,endoscopic image ,performer′s perception ,and spatial orientation were evaluated .Results The maneuverability of trangastric ,and transrectal approach NOTES were better than transunmbilical NOTES .Abdominal exploration ,live biopsy ,and bladder biopsy were completed successfully .The cholecystectomy was failed because of poor exposure and difficulty of separating the around tissure .Conclusion The optimal approach for upper abdomen NOTES is transrectal route .For lower abdomen NOTES , the trangastric approach is superior to other accesses .Further study is needed to develop more flexible and precise equipment for NOTES and to evaluate more feasible access approach .
