ObjectiveTo investigate the effectiveness and impact of low‐pressure pneumoperitoneum (Pnp) on postoperative quality of recovery (QoR) and surgical workspace (SWS) in patients with prostate cancer undergoing robot‐assisted radical prostatectomy (RARP).Patients and MethodsA randomised, triple‐blinded trial was conducted in a single centre in Denmark from March 2021 to January 2022. A total of 98 patients with prostate cancer undergoing RARP were randomly assigned to either low‐pressure Pnp (7 mmHg) or standard‐pressure Pnp (12 mmHg). Co‐primary outcomes were postoperative QoR measured via the QoR‐15 questionnaire on postoperative Day 1 (POD1), POD3, POD14, and POD30, and SWS assessed intraoperatively by a blinded assessor (surgeon) via a validated SWS scale. Data analysis was performed according to the intention‐to‐treat principle.ResultsPatients who underwent RARP at low Pnp pressure demonstrated better postoperative QoR on POD1 (mean difference = 10, 95% confidence interval [CI] 4.4–15.5), but no significant differences were observed in the SWS (mean difference = 0.25, 95% CI −0.02 to 0.54). Patients allocated to low‐pressure Pnp experienced statistically higher blood loss than those in the standard‐pressure Pnp group (mean difference = 67 mL, P = 0.01). Domain analysis revealed significant improvements in pain (P = 0.001), physical comfort (P = 0.007), and emotional state (P = 0.006) for patients with low‐pressure Pnp. This trial was registered at ClinicalTrials.gov, NCT04755452, on 16/02/2021.ConclusionPerforming RARP at low Pnp pressure is feasible without compromising the SWS and improves postoperative QoR, including pain, physical comfort, and emotional state, compared to the standard pressure.

Background: A sufficient surgical workspace is crucial to avoid complications.Within classic laparoscopy, many subjective surgical rating scales (SRSs) have previously been used to evaluate the surgical workspace. This study aimed to validate a modified version of the 5-point SRS during robot-assisted radical nephrectomy (RARN).Methods: Thirty-two intra-operative videos of intraperitoneal spaces were recorded from eight patients who underwent RARN. To attain the visualisation of different types of workspaces, we recorded 20 s panoramic videos of different pneumoperitoneum, namely 3, 5, 7 and 12 mmHg. The videos were randomised and presented two times to eight experienced robotic surgeons to evaluate the workspace using our modified 5-point SRS. Both inter-and intra-rater reliabilities were tested. Results:The results of the validation study showed moderate inter-rater and good to excellent intra-rater reliability. Conclusion:This is a valid tool that can be confidently used by future researchers in the field of robot-assisted surgery.
