Laparoscopy for living donor left nephrectomy: Comparison of three‐dimensional and two‐dimensional vision

Abstract

The main objective of this preliminary study was to evaluate the feasibility and safety of 3‐D laparoscopic living donor left nephrectomy (LDLN). The secondary objective was to compare intraoperative and postoperative outcomes between 3‐D and 2‐D laparoscopic LDLN. All patients who underwent a laparoscopic LDLN from January 2015 to April 2018 in a university center were included. All surgeries were performed by three experienced surgeons. Seventy three patients were included the following: 16 underwent a 3‐D laparoscopic LDLN (3‐D group), and 57 underwent a 2‐D laparoscopic LDLN (2‐D group). Operative time and warm ischemia time (WIT) were significantly lower in the 3‐D group (operative time: 80.9 ± 10.2 vs 114.1 ± 32.3 minutes in the 3‐D and 2‐D groups, P = .0002) (WIT: 1.7 ± 0.6 vs 2.3 ± 0.9 minutes in the 3‐D and 2‐D groups, P = .02). No conversion to open surgery occurred in both groups. Length of hospital stay was significantly shorter in the 3‐D group. No major postoperative complications (Clavien ≥ III) occurred. One‐year postoperative GFR was similar to 3‐D and 2‐D groups. Our preliminary study demonstrates that 3‐D laparoscopic LDLN is a feasible and safe surgical procedure. Intraoperative and postoperative outcomes were similar in both 2‐D and 3‐D vision systems, but 3‐D vision systems allow reduction in WIT and operative time.

Clinical experience of bench surgery combined with autotransplantation after three-dimensional laparoscopic nephrectomy for the treatment of highly complex renal tumor

“…This time was similar to the results of Prudhomme et al, who suggested that 3D laparoscopic kidney extraction was significantly superior to 2D laparoscopic system in terms of total operation time (80.9 ± 10.2 vs. 114. 1 ± 32.3 min in 3D and 2D, p = 0.0002) and warm ischemia time (1.7 ± 0.6 vs. 2.3 ± 0.9 min in 3D and 2D, p = 0.02), these findings might be attributed to the improved speed of the 3D laparoscopic system in terms of vessel separation and ligation [ 21 ]. The tumor resection and the transplanted kidney repair were all performed after immersion in cryogenic perfusion fluid.…”

Two- and three-dimensional laparoscopic donor nephrectomy: a comparative study of a single-center experience

“…In the available literature, we found only one study that compared 3D and 2D laparoscopic donor nephrectomy [ 28 ]. Therefore, we believe that the number of such articles is not enough to show statistically meaningful differences.…”
