Abstract: Objective To evaluate the feaibility and safety of gastrotomy in natural orifice transluminal endoscopic surgery(NOTES)using technique of percutaneous endoscopic gastostomy(PEG).Methods To retrospectively investigate and compare the success rate,complications and procedure time of gastrotomy in NOTES of dogs between PEG-like approach(PEG group,n =20)and needle knife incision(needle knife group,n =18).Results Gastrotomy was successfully performed in all animals.No mass bleeding or organ injury was observed in PEG group,while one dog in needle knife group encountered mass bleeding,and injuries to the adjacent organs were found in 3 others(0％ in PEG group vs.22％ in needle knife group,P ＜ 0.05).The procedure time of gastrotomy in PEG group was longer than that of needle knife group (15.0±3.7 min vs.6.0 ± 1.1 min,P ＜0.05).Conclusion Compared with the techniqued of needle knife incision,gastrotomy using PEG-like approach in NOTES is safe and feasible.
