An analysis of post-operative pain and narcotic use following robotic assisted laparoscopic prostatectomy for same day discharge.

Robotic assisted laparoscopic prostatectomy (RALP) has become the primary surgical modality in the treatment of prostate cancer. Most patients are discharged on postoperative day one. Same-day discharge is emerging as a potential new standard. We sought to establish factors correlating with post-operative pain after RALP procedures to design a same-day discharge protocol. We retrospectively reviewed 150 of recently performed RALP procedures from March 2020 to January 2021. Patient demographics and intra-operative variables were compared to Numeric Rating Scale (NRS) pain scores and total morphine milliequivalents (MME) at 2 h, 8 h, and averaged over the patient's admission post-operatively or first 48 h, whichever occurred first. We performed univariable and multivariable logistic regression to assess correlations with postoperative pain and narcotic use. NRS average > 3 or any MME given at 2 h postoperatively was significantly associated with continued post-operative pain averaged over admission (rs = 0.32, 0.38, respectively; p < 0.001). MME given was also associated with longer operative time and negative related to body mass index. No other demographic data or intraoperative variables such as diabetes or pneumoperitoneum pressure were correlated with worsened post-operative pain scores > 3 or narcotic use. Local bupivacaine dose was also not associated with improved post-operative pain scores or narcotic use at 8 h (p = 0.98, 0.13). These findings suggest that patients with adequate postoperative pain control at 2 hours may be discharged same day from a pain control perspective. Further clinical evaluation regarding the role of local anesthetic use in RALPs is warranted.

Initial Experience with Single-Port Robot-Assisted Radical Cystectomy: Comparison of Perioperative Outcomes Between Single-Port and Conventional Multiport Approaches.

Background: The surgical techniques and devices used to perform radical cystectomy have evolved significantly with the advent of laparoscopic and robotic methods. The da Vinci® Single-Port (SP) platform (Intuitive Surgical, Inc., Sunnyvale, CA) is an innovation that allows a surgeon to perform robot-assisted radical cystectomy (RARC) through a single incision. To determine if this new tool is comparable to its multiport (MP) predecessors, we reviewed a single-surgeon experience of SP RARC. Materials and Methods: We identified patients at our institution who underwent RARC between August 2017 and June 2020 by one surgeon at our institution (n = 64). Using propensity scoring analysis, patients whose procedure were performed with the SP platform (n = 12) were matched 1:2 to patients whose procedure was performed with the MP platform (n = 24). Univariable analysis was performed to identify differences in any perioperative outcome, including operative time, estimated blood loss (EBL), lymph node yield, 90-day complication/readmission rates, and positive surgical margin (PSM) rates. Results: Patients who had an SP RARC on average had a lower lymph node yield than those who had an MP RARC (11.9 vs 17.1, p = 0.0347). All other perioperative outcomes, including operative time, EBL, 90-day complication rates, 90-day readmission rates, and PSM rates, were not significantly different between the SP and MP RARC groups. Conclusions: Based on their perioperative outcomes, the SP platform is a feasible alternative to the MP platform when performing RARC. The SP's perioperative outcomes should continue to be evaluated as more SP RARCs are performed.
