Impact of continuous local anesthetic wound infiltration on postoperative outcomes following open radical cystectomy: a comprehensive evaluation
摘要
To evaluate continuous wound infiltration (CWI) as an alternative to thoracic epidural analgesia (TEA) for postoperative recovery after open radical cystectomy within an ERAS® pathway.
Materials and methodsRetrospective before–after cohort at a Swiss tertiary center using a prospectively maintained ERAS® database (TEA: Nov 2012–May 2016; CWI: Jun 2016–Mar 2024). Adults undergoing open cystectomy with extended pelvic lymphadenectomy and ileal conduit or neobladder were included (CWI = 154; TEA = 88). Outcomes were daily pain (VAS 0–10), nausea, opioid rescue (POD0–3), gastrointestinal recovery (first stool; tolerance of solid food), length of stay (LOS), and 90-day complications. Mixed-effects and multivariable models adjusted for prespecified covariates.
ResultsPain scores were lower with TEA on POD0–3, whereas CWI had less postoperative nausea. CWI showed faster bowel recovery (first stool median 5 vs. 6 days, p = 0.02) and earlier tolerance of solid food (median 5 vs. 11 days, p < 0.001; adjusted β − 4.4 days, 95% CI − 6.8 to − 2.1). LOS was shorter with CWI (median 15 vs. 24 days, p < 0.001; adjusted β − 5.0 days, 95% CI − 9.1 to − 1.0). Early opioid rescue was more frequent with CWI, attenuating by POD3. No CWI catheter-related complications occurred.
ConclusionWithin ERAS®, CWI with ropivacaine is a clinically acceptable alternative to TEA after open RC, trading slightly higher early pain for faster gastrointestinal recovery and a shorter LOS.
