[A pilot study of endoscopic experimental transgastric peritoneoscopy and endoscopic gastrorrhaphy in a canine model.].
OBJECTIVE
Natural Orifice Translumenal Endoscopic Surgery (NOTES) is an experimental technique with potential advantages compared to laparoscopic surgery. Trans gastric peritoneoscopy (TP) is a NOTES technique. The aim of this study was to perform TP, to evaluate feasibility and technical limitations in a survival model.


METHODS
The following procedures were performed in 4 anesthetized dogs using a single channel video gastroscope: Gastrotomy with needle-knife puncture followed with extension of the incision with a pull-type sphincterotome,pneumoperitoneum with the endoscope,peritoneoscopy and gastrorrhapy using hemoclips and endoloops.


RESULTS
All the procedures were accomplished successfully with a mean duration of 80 minutes. Gastrotomy induced minor bleeding.Peritoneal cavity was accessed safely and peritoneoscopy was accomplished without incidents.Retroflexed maneuvers were mandatory to visualize upper abdomen and overinflation oftenly occurred. The closure of the gastric wall incision was successfully obtained. All the animals made an uncomplicated recovery after 7 days.


CONCLUSIONS
TP is technically feasible and safe in a canine model. This study highlights several technical limitations and confirms the need for technological development.
