POMILIO DI LORETO, Franco N. et al. Preoperative sonography eficacy for cholecystoscopy cannula orientaton, evaluaton on pigs. Rev. argent. cir. [online]. 2018, vol.110, n.1, pp.1-10. ISSN 2250-639X.

Background: the Cholecystoscopic Cholecystosclerosis is a single session procedure, under enhancing process, which pursues a definitive Gallbladder eliminaton by means of stone removal and mucous membrane ablaton through Operatory Cholecystoscopy, under local-regional anesthesia, and requires the inserton of a Cholecistoscopy Cannula from the abdominal wall toward the gallbladder fundus. Objective: to assess the efectiveness of the Preoperative Sonography when it comes to finding the right place for the Cholecystoscopy Cannula inserton. It is important to achieve the Cholecystoscopy Cannula being introduced in a way that its axis matiches the Gallbladder´s axis, in order to provide a suitable passage for instruments between the Cannula and the Gallbladder´s lumen. Material and Method: preoperative sonography was planned to be performed in a series of surgical interventons on pigs, in order to determine the positon of the gallbladder in its three spatal dimen-sions, allowing a virtual projecton of the organ´s axis toward the abdominal wall, thus pointing to the most suitable place for the Cholecystoscopy Cannula inserton. Results: fve procedures were performed as planned, the Cholecystoscopy Cannula rapidly reached the gallbladder fundus and coincidence between cannula axis and gallbladder axis was achieved in all the cases. Conclusions: preoperative sonography seems to be very eficient for choosing the right place for Cholecystoscopy Cannula inserton accordingly to this experience.
