Erector Spinae Plane Block for Pain Management in Hepatocellular Carcinoma Patients Undergoing Laparoscopic Left Hemihepatectomy: A Retrospective Propensity Score-matched Study

ESPB serves as an efficacious ancillary analgesic for laparoscopic left hemihepatectomy, offering superior pain management and recuperation relative to the administration of intravenous analgesia in isolation. The implementation of ESPB as an adjunct to PCA in patients with hepatocellular carcinoma undergoing laparoscopic left hemihepatectomy proved to be both safe and efficacious. Notably, PCA augmented with ESPB demonstrated greater efficacy in mitigating postoperative pain compared with PCA as a standalone therapy.
