Safe transition from open to pure laparoscopic donor nephrectomy: Approach and results

Abstract

Introduction: Laparoscopic living donor nephrectomy (LLDN) offers many advantages compared to open living donor nephrectomy. However, the perceived difficulty in learning LLDN has slowed its wider implementation. Herein, we describe the evolution of LLDN at a single center, emphasizing the approach and technical modifications and its impact on outcome. Methods: The series included a 2½-year period and three different surgeons. We started with two-stage plan for establishing LLDN at the institute (introduction and consolidation). Data of laparoscopic donor nephrectomy performed at the institution were prospectively evaluated regarding donor and recipient outcome. Results: From December 2016 to April 2019, 221 donors underwent LLDN. Three donors required conversion to open surgery. The mean operation time was 96.4 (62–158) min and the mean warm ischemia time was 186 (149–423) s. The complications were observed in 11.6% of donors from LLDN group and all complications were Class I and Class II only (Clavien–Dindo classification). No Class III and Class IV complications occurred. In the present study, there was some learning curve effect observed only in operative time (OT) with longer OT in initial cases. However, the overall operative complications were minimal, showing that this learning curve had no deleterious effects on donor safety. Conclusion: The present study demonstrates that with proper planning, team approach, and a few technical modifications, the transition from open to LLDN could be safe and effective.
