Single-Shot Ultrasound-Guided Transversus Abdominis Plane Block Versus Intravenous Patient-Controlled Analgesia for Early Recovery After Laparoscopic Cholecystectomy: A Retrospective Cohort Study.

ABSTRACT: Background: Effective postoperative analgesia after laparoscopic cholecystectomy (LC) should facilitate rapid recovery while minimizing exposure to opioid-related adverse events, a central goal of enhanced recovery after surgery (ERAS). Although intravenous patient controlled analgesia (IV-PCA) remains widely used, its gastrointestinal and mobilization-impairing side effects may hinder early recovery. Methods: This retrospective cohort study included adult patients who underwent elective laparoscopic cholecystectomy, all performed using a standardized three-port technique, between January 2025 and December 2025. Patients with conversion to open surgery, concurrent procedures, incomplete medical records, or American Society of Anesthesiologists physical status ≥ IV were exclud
