RESUMEN
A new concept for minimally invasive treatment involves abdominal laparoscopic surgery performed while the patient breathes independently without losing consciousness. Here we report the first series of laparoscopic partial nephrectomy (LPN) performed under neuroaxial anesthesia (NA). From May 2021 to September 2022 we prospectively enrolled selected patients with an organ-confined single renal mass to undergo LPN under NA. Anesthesia was administered using an epidural catheter placed at the level of T7, with additional anesthesia at the level of T10. The rationale was to avoid use of a tracheal tube and the side effects of general anesthesia. Ten patients were enrolled in the study. Targeted sedation was achieved in all cases. In one case, a switch to general anesthesia was needed because of patient anxiety. Food intake started at 12 h after surgery in 9/10 cases; mobilization started from 3 h after surgery. The length of hospital stay was 3 d in 4/10 cases and 4 d in 3/10 cases. This first experience worldwide of LPN performed under NA demonstrates the feasibility and safety of the procedure.
RESUMEN
Objective: Neuraxial anesthesia (NA) showed to reduce both morbidity and mortality in patients undergoing laparoscopic surgery. We aimed to investigate the use of NA in patients undergoing transperitoneal three-dimensional laparoscopic radical prostatectomy (t-3DLRP) and compare the intraoperative and postoperative outcomes with a control group of patients undergoing t-3DLRP under general anesthesia (GA). Methods: A prospective, double-center, double-surgeon study cohort of 84 consecutive patients undergoing t-3DLRP between June 2019 and June 2021 was analyzed. A study group of 42 patients undergoing t-3DLRP under NA was compared with a control group of 42 patients undergoing t-3DLRP under GA. Results: The two group were similar in all demographic, clinical, and pathological variables. Postoperative blood gas parameters were within physiologic limits in both groups. Muscle relaxation was adequate for surgery during both NA and GA. Median length of stay was 1 day shorter for NA group than GA group (5 days vs. 6 days, p=0.05). t-3DLRP under NA had a statistically lower rate of minor complications (4.8% vs. 19.0%, p=0.03) and less postoperative pain (median numeric rating scale 3 vs. 4, p=0.01) compared to GA. No major complications were observed in both groups. Significantly more patients were willing to undergo a similar intervention under NA than GA (p=0.04). Conclusion: t-3DLRP under NA is a feasible and safe procedure, with less postoperative pain and fewer minor complications than the same procedure under GA. NA allows the maintenance of muscle relaxation and respiratory excursions without interfering with surgery.
