Comparison of 3D and 2D laparoscopic nephron sparing surgery for renal tumor

Abstract

Objective To compare clinical outcomes of 3D laparoscopic nephron sparing surgery for renal tumors with traditional 2D laparoscopic surgery.Methods Clinical data on 85 patients who underwent laparoscopic nephron sparing surgery for renal tumors were collected.All the patients were divided into observation group and control group.The observation group included 38 cases,who received 3D laparoscopic nephron sparing surgery.The control group included 47 cases,who received traditional laparoscopic nephron sparing surgery.Demographic data,perioperative parameters and clinical outcomes were collected and compared between the 2 groups.Results Demographic data on patients were similar in the 2 groups.In the observation group such perioperative parameters were significantly different from those of control group,including operative time (81.4± 11.8 versus 93.5± 17.4 min,P＜0.05) and renal warm ischemia time (19.9± 3.2 versus 22.3±3.6 min,P＜0.05).However,the estimated blood loss,postoperative hospital stay,total hospitalization charge and postoperative complications were similar between the 2 groups (P＞0.05).3D laparoscoy provided a three-dimentional view of operation field,which make the suturing and knotting easier and reduce the difficulty of operation.During the follow-up period for 2 to 11 months,no tumor recurrence and/or metastasis developed.Conclusions Compared with the traditional 2D laparoscopic technology,3D laparoscopic technology has obvious advantage in spatial location and the sense of depth.To some extent,3D laparoscopy reduces the operation difficulty,and shortens the operative time and renal warm ischemia time.
