A Comparative Analysis of Erector Spinae Plane Block Versus Conscious Sedation in Managing Percutaneous Cholecystostomy Pain.

Purpose: This study investigates the efficacy of erector spinae plane block (ESPB) for managing perioperative and postoperative pain in patients undergoing percutaneous cholecystostomy (PC) for acute cholecystitis, particularly in high-risk elderly patients with extensive comorbidities and limited functional status.
Methods: In a retrospective single-center study, 58 high-risk patients scheduled for PC were assessed. ESPB was administered to 23 patients, while 22 received conscious sedation. Pain intensity was measured using the numeric rating scale before any analgesic or ESPB administration, during the procedure and at 1 and 12 h post-procedure and secondary outcomes included adverse effects and additional analgesic requirements.
Results: The ESPB group experienced significant pain reduction during and post-procedure compared to the conscious sedation group (p = 0.002). Procedure times were shorter (p = 0.015), and postoperative tramadol was less frequently needed in the ESPB group (p = 0.007). The incidence of nausea was also lower in the ESPB group (p = 0.001). No ESPB-related complications were reported.
Conclusion: ESPB significantly alleviates perioperative and postoperative pain in PC patients, reducing additional analgesic use and side effects. It holds promise as a key component of pain management for high-risk surgical patients.
Level of Evidence: Level 3, Non-randomized controlled cohort/follow-up study.
