摘要
Data on safety and efficacy of robot-assisted radical prostatectomy (RARP) after previous abdominal surgery are scarce. Hence, we assessed perioperative, oncological and functional outcomes, and complications of RARP in patients with previous abdominal surgery after 1-year minimum follow-up. Prospectively collected data from 339 consecutive patients undergoing transperitoneal RARP by a single surgeon (AM) between November 2008 and May 2014 were analysed. Complications were classified according to Modified Clavien System. Biochemical recurrence (BCR) was defined as two consecutive PSA values ≥ 0.2 ng/ml. Functional outcomes were assessed using validated, self-administered questionnaires. In particular, only patients undergoing nerve-sparing RARP with no erectile dysfunction (baseline IIEF-5 score >21) and no use of phosphodiesterase-5 inhibitors preoperatively who were interested in erections and required no adjuvant therapy (radiation, orchiectomy and androgen-deprivation therapy) were evaluated concerning potency recovery. Patients without and with previous abdominal surgery were compared using Mann-Whitney and chi-square tests (or Fisher exact test). On 339 patients, 247 (71.6%) had not undergone previous abdominal surgery (Group 1) and 92 (28.4%) were pre-operated (Group 2). There were no statistically significant differences between Groups 1 and 2 regarding mean operative time (260 vs. 257 min; p = 0.597), median number of resected nodes (16 vs. 17; p = 0.484), mean length of stay (7.2 vs. 7.1 d; p = 0.151), positive surgical margin (12.5% vs. 16.3%; p = 0.233) and complication rates (26.7% vs. 31.5%; p = 0.187). Median (IQR) follow-up was 36 (12–48) months. For Groups 1 and 2, BCR-free survival rates were 78.5% and 79.8% (p = 0.467); continence rates were 97.9% and 100% (p = 0.329), whereas a potency recovery was achieved in 69.5% and 62.2% of patients (p = 0.460), respectively. Transperitoneal RARP is a safe and efficient treatment for clinically localised prostate cancer even in patients with previous abdominal surgery. However, further studies with higher number of patients are warranted.
