Purpose: To evaluate the feasibility and safety of the extraperitoneal robotic radical prostatectomy (ERP), we compared the results of transperitoneal robotic radical prostatectomy (TRP) with those of ERP performed by a single surgeon.
Materials and Methods: All operation was performed by a single surgeon, who had the experience of more than 150 transperitoneal cases. Recently, 30 cases were performed through transperitoneal approach, and then extraperitoneal approach was applied to next 30 cases. We compared the clinicopathologic parameters and perioperative outcomes between two groups.
Results: There were no significant differences in mean age, body mass index (BMI), preoperative prostate-specific antigen (PSA) level, prostatectomy Gleason scores and pathologic T stage between two groups, whereas positive surgical margin rate was significantly lower in ERP. There was no significant difference in total operation time, whereas console time, and vesicourethral anastomosis time significantly decreased in ERP. There were no significant differences in postoperative normal diet start day, the duration of hospital stay and bladder catheterization. There were no significant differences in the amount of estimated blood loss and the number of resected lymph nodes. In both groups, there were no inadvertent organ injury during trocar placement and conversion to open surgery, whereas 1 case of lymphocele in ERP was recovered with conservative care.
Conclusions: ERP showed similar perioperative outcomes compared to TRP. Considering the potential risk of bowel injury in TRP and reduced peritoneal irritation in ERP, ERP may be alternative in robotic radical prostatectomy.
