Periprostatic Fat Area Is an Independent Factor That Prolonged Operative Time in Laparoscopic Radical Prostatectomy

摘要: Objective To evaluate the effect of visceral obesity on surgical outcomes in laparoscopic radical prostatectomy (LRP). Methods Visceral fat area (VFA) and periprostatic (PPFA) were used as index obesity. In addition to VFA PPFA, age, body mass (BMI), prostate weight, cross-section Retzius space, history previous abdominal surgery, repeated transrectal needle biopsy, neoadjuvant hormone therapy recorded. LRP was separated into 7 steps (1: port insertion lymph node dissection, 2: endopelvic fascia incision, 3: dorsal vein complex ligation, 4: dissection from bladder neck, 5: seminal vesicle vas deferens, 6: rectum, 7: vesicourethral anastomosis). Potential factors that prolonged total operative time (OT), pneumoperitoneum time, duration each step assessed by multivariate logistic regression analysis. The association between other also evaluated. Results One hundred sixteen LRPs performed a single experienced surgeon. High PPFA weight independent OT time. BMI not factor. affected 1, 4, 5, 6, 5 6.
