ABSTRACT

Objective: To proposed a surgical educational procedure for laparoscopic gastrostomy in the rabbit, which is both didactic and low-priced.
Setting: Surgery department; Universidad Nacional Autonoma de Mexico UNAM.
Design: Descriptive, experimental study. Statistical analysis: not require.
Material and methods: Five healthy male rabbits, New Zealand breed, weighing between 2,500 and 3,500 kg, were used. In the surgical room, under general anesthesia and endotracheal intubation, carbon dioxide was insufflated into the abdominal cavity. The camera was introduced through a 10-mm trocar, and a 5-mm trocar was used to introduce the instrument to move the stomach. Percutaneously, four “T”-sutures were performed using a fenestred needle to hold the stomach, like a hammock. Through its center and under direct endoscopic vision, a wire guide was passed to reach the gastric lumen. The wire guide was used to introduce the dilators and a gastrostomy catether, the balloon was insuflated and the “T” sutures were retracted and ligated in the exterior. This maneuver served to fix the anterior gastric wall to the parietal peritoneum, and the abscence of leakage was confirmed. Eight days thereafter, by means of X rays, we confirmed fixation of the stomach to the abdominal wall and the absence of gastric content leaks.
Results: In the rabbit, “T” sutures are safe and fix adequately the stomach to the abdominal wall, keeping the gastrostomy catheter in place and without leaks.
Conclusions: Gastrostomy with laparoscopic technique and fixation with “T” sutures, in the experimental animal (rabbit), is a feasible, reproducible, useful, safe and cheapsurgical procedure. Therefore, it is proposed to be validated as an educational model in the teaching of laparoscopic surgery.
