Abstract

In this study, we aimed to verify the feasibility of the multidirectional traction platform in performing gasless laparoscopic nephrectomies on dog cadavers. The cadavers were divided into two groups: those subjected to gasless laparoscopic radical nephrectomy (GCG) and those subjected to laparoscopic radical nephrectomy with pneumoperitoneum (GCP). The total surgical time, time for each stage of the procedure, and intraoperative complications were recorded. Using the Likert scale and visual analog scale (VAS), the surgeon and assistant assessed the degree of difficulty of each surgical approach. The total surgical time for nephrectomy was longer in the GCG group (p
