Laparoscopic adrenalectomy: comparison between pneumoperitoneum and the use of a laparoscopic lift device in dog cadavers

Adrenalectomia laparoscópica: comparação entre o pneumoperitônio e o uso de dispositivo paraliftlaparoscopyem cadáveres de cães

ABSTRACT:

This study evaluated the feasibility of abdominal liftfor laparoscopic adrenalectomy and compared it with the conventional laparoscopic technique using pneumoperitoneum with medicinal CO₂ in dog cadavers. The total surgical time (TST), adrenalectomy time (AT), and gland integrity after removal were evaluated. Thirty-eight adrenalectomies were performed in 19 cadavers. Regardless of the antimere, the TST was significantly lower in the CO₂ procedures than in the lift laparoscopy procedures (P=0.001). When comparing the techniques between antimeres, the TST was significantly higher on the left side with lift laparoscopy than with CO₂ (P=0.015) and similar between the techniques on the right side of the animals (P=0.086). In the comparison of AT, regardless of the execution side, no differences were observed between the techniques (P=0.05). The same was observed when AT was evaluated separately using antimeres (P=0.902). Of the 38 adrenals evaluated, 92.1% were removed in a single block, and 32.29% had a superficial lesion in the capsule. There was no difference between the groups in the removal capacity in a single block (P=0.340) and capsule integrity (P=0.287). Abdominal lift for laparoscopic adrenalectomy is a feasible technique in dog cadavers; however, it requires a longer surgical time than the conventional technique. The traction force used to elevate the abdominal wall must be evaluated.
