Comparison of a Novel Endoscope Holder and Traditional Camera Assistant for Laparoscopic Simple Nephrectomy in a Porcine Model

Purpose: To establish the feasibility of single-surgeon laparoscopy with application of a novel endoscope-holder device and to compare this technique with traditional assistant-driven laparoscopic camera control. Materials and Methods: Bilateral simple nephrectomies were performed in six pigs. On one side, the operating surgeon employed the "scope holder" and performed the surgery without a laparoscopic assistant. On the contralateral side, an experienced camera operator was responsible for control of the laparoscopic field of vision in the traditional manner. The time required for hilar ligation and complete renal mobilization was documented. Pigs were sacrificed immediately after the procedure. Results: The mean operative times for scope-holder and camera person-assisted nephrectomy were 20.7 minutes and 19.3 minutes, respectively. The time to hilar ligation in the scope-holder and camera-operator-assisted cohorts was 13 and 14.5 minutes, respectively. There were no significant differences in operative ...
