BACKGROUND: Beforehand transection and suturing (BTS) of the dorsal vascular complex (DVC), a novel technique in non-neurovascular bundle sparing (NVB-sparing) extraperitoneal laparoscopic radical prostatectomy (eLRP), had been proposed; this study aimed to evaluate this technique in clinical laparoscopic procedures. METHODS: Using this new technique, the DVC was transected and sutured after dissection of the pelvic fascia and before dissection of the prostate, especially before ligation of the bilateral prostatic pedicles. This study retrospectively analyzed the data of 90 non NVB-sparing eLRP patients [traditional technique (n=60) and BTS technique (n=30)]. RESULTS: The surgical time in the BTS technique group was 121.73±24.53 min, which was significantly shorter (P=0.0015) than the traditional technique group (144.12±39.68 min). The calculated blood loss in the traditional technique group was 388.45±232.78 mL, and 264.16±130.70 mL in the BTS technique group (P=0.0016). The estimated blood loss in the traditional technique group was 350.34±311.80 mL, which was significantly greater than the BTS technique group (250.33±145.31 mL, P=0.0422). The transfusion rate in the traditional technique group was significantly greater than the BTS technique group (15.00% vs. 0.00%; P=0.0266). The biochemical recurrence rate in traditional technique group was 48.33%, which was higher than in the BTS group (30.00%) (P=0.0465). There was no significant difference between the 2 groups with respect to the pre-operative hemoglobin (Hb) concentration, pre-operative hematocrit (HCT), post-operative Hb concentration, post-operative HCT, ΔHCT, pre-operative blood volume, rectal perforation, open conversion, apical capsule residue, false suture, post-operative bleeding, urinary leakage, re-operation, surgical site infection, post-operative stay, and emission time of urinary incontinence. CONCLUSIONS: In managing the relationship between the DVC and prostate in patients undergoing non NVB-sparing eLRP, the BTS technique was shown to be more effective and safer than the traditional technique. 2020 Gland Surgery.
