Abstract: Objective To investigate the feasibility and safety of trans-gastric route combined with trans-colonic or trans-vaginal route endoscopic salpingectomy and liver biopsy, as methods of natural orifice translumenal endoscopic surgery (NOTES). Methods Endoscopic salpingectomy and liver biopsy were per-formed in 4 female porcine models, in 2 of which the procedure was achieved via trans-gastric and trans-co-Ionic route (Group A), while in other 2 was via trans-gastric and trans-vaginal route (Group B). The ani-mals were sacrificed after the procedure and the related complications were observed. Results Abdominal cavity exploration, salpingectomy and liver biopsy could be performed successfully through two combined routes. Perforation of adjacent colon was found in 1 animal with the trans-colonic route NOTES. Conclusion NOTES via trans-gastric and trans-colonic routes or via trans-gastric and trans-vaginal for salpingectomy and liver biopsy are both feasible, while trans-vaginal route seems to be safer than trans-colunic route.
