[Clinical efficacy of dorsal venous complex pre-suture technique in the robot-assisted laparoscopic radical prostatectomy].

The clinical data of 33 patients who underwent robot-assisted laparoscopic Vattikuti Institute prostatectomy (VIP) in Cancer Hospital of Chinese Academy of Medical Sciences from October 2020 to April 2022 were reviewed and analyzed. Among them, 18 patients received traditional VIP technique and 15 patients received VIP technique with pre-sutured dorsal venous complex (DVC). The ages of the traditional VIP group and the pre-sutured DVC VIP group were (66.1±7.3) and (66.6±5.7) years, respectively. The body mass index (BMI) of the traditional VIP group and the pre-sutured DVC VIP group was (24.3±2.9) and (25.3±2.6) kg/m², respectively. The medical expenses were (91 797.0±7 029.6) and (87 106.6±7 031.4) yuan, respectively, with no statistical significance (all P>0.05). The operations of all the 33 cases were successfully completed, and no cases were transferred to open surgery. The operation time of traditional VIP group was longer than that of pre-sutured DVC VIP group [(193.0±37.2) vs (171.1±16.1) min]. The amount of intraoperative blood loss was higher than that in the pre-sutured DVC VIP group [(68.3±22.8) vs (44.0±9.1) ml)], all P<0.05. No patients had perioperative blood transfusion, and no patients had complications within 30 days after surgery. All the 33 patients had negative incisal margins. DVC presuture technique can reduce intraoperative bleeding and shorten operative time in robot-assisted laparoscopic VIP radical prostatectomy, and has good curative effect.
