LAPAROSCOPIC CHOLECYSTECTOMY ASSISTED WITH MAGNETS IN SWINE EXPERIMENTAL MODELS

Abstract

Objetive: Characterize laparoscopic cholecystectomy with two (2) ports assisted by magnets in a swine experimental model (Sus scrofa domesticus) as an alternative to surgical training. Method: Five (5) experimental swine models (Sus scrofa domesticus) undergoing laparoscopic cholecystectomy with two (2) ports (umbilical and epigastric) assisted by magnets, using the conventional technique performed by different surgeons. Results: Five (5) laparoscopic cholecystectomy two (2) ports assisted by magnets were performed. The average weight of the animals was 46,8±7,95 Kg (36-56), mean operative time 102±10,37 minutes (90-115) and bleeding 65±62,75 cc (25-175). There were no complications or conversions. All animals survived the procedure. Conclusions: Laparoscopic cholecystectomy with two (2) ports assisted by magnets in swine experimental model is an ideal training method for this new technique. Despite being a reproducible and safe procedure, is also a challenging surgical, represented by the learning curve required for handling the magnetic devices. This procedure has the advantages offered by minimally invasive without sacrificing the benefits of the traditional technique.
