Application of modified VIP technique in robot-assisted laparoscopic radical prostatectomy(with surgical video)
Objective:To investigate the clinical efficacy of modified Vattikuti Institute Prostatectomy(VIP)technique in patients underwent robot-assisted laparoscopic radical prostatectomy(RARP)for localized prostate cancer.Methods:Clinical data of 53 patients with localized prostate cancer who underwent RARP in Baoji Central Hospital from January 2022 to June 2023 were retrospectively analyzed.According to the different surgical approaches,they were divided into the standard anterior approach robot-assisted laparoscopic radical prostatectomy(SA-RARP)group(n=24)and modified VIP RARP(MV-RARP)group(n=29).Perioperative indicators and follow-up data were collected and compared between the two groups.Results:All surgeries were successfully completed without conversion to open surgery or secondary surgery.There were no statistically significant differences in general data of patients in the two groups(P>0.05).The differences in operative time,intraoperative bleeding,intraoperative blood transfusion rate,postoperative hospitalization time,drainage tube removal time,postoperative catheter removal,positive surgical margin rate,enlarged lymph node dissection rate,positive lymph node rate,Gleason score,and clinical stage of the two groups were not statistically significant(P>0.05).Compared with the SA-RARP group,the MV-RARP group had better immediate urinary control,early urinary control and 3-month urinary control,and higher IIEF-5 score(P<0.05).Kaplan-Meier curve was used to analyze the survival time without biochemical recurrence in the two groups,and the difference was not statistically significant(Log-Rank:χ 2=0.889,P=0.346).The Kaplan-Meier survival analysis indicated that the difference in recovery rate of urinary control of the two groups was statistically significant(Log-Rank:χ 2=4.314,P=0.038).Conclusion:The modified VIP technique is a precise and safe technique in RARP for prostate cancer,which can improve the recovery rate of early postoperative urinary control and postoperative erectile function by ensuring good tumor control.
