A Comparison of Perioperative Outcomes Between Single-port and Multiport Robot-assisted Laparoscopic Prostatectomy.

Abstract

Single-port (SP) robot-assisted laparoscopic prostatectomy (RALP) appears to be a safe and feasible approach for radical prostatectomy, but no prior studies have compared SP-RALP to a multiport (MP) platform. Using retrospective data from a single-center tertiary institution we compare 50 consecutive SP-RALP patients (da Vinci SP) to a contemporary cohort of 113 patients who underwent MP-RALP (da Vinci Xi). We found no significant differences in surgical or total operating room time. Pain scores were measured on a scale from 0 to 10. There were more pain-free patients on postoperative day 1 (18% difference, 95% confidence interval [CI] 9.9-27%) and there were shorter hospital stays (-1 d, 95% CI -1.0 to 0) in favor of SP. There were no significant differences in inpatient total morphine equivalents used, complication rates, or stress incontinence determined at a minimum of 90 d. These findings show that the learning curve for SP-RALP is relatively short for an experienced robotic surgeon and may favor better pain control and shorter hospitalization. PATIENT SUMMARY: We analyzed the differences in robotic surgery for localized prostate cancer using a single-port robotic platform compared to the traditional multiport robotic platform. We did not find significant differences in operative times, but significantly more patients were pain-free on the first postoperative day and had shorter hospital stays.
