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 \u2265 IV were excluded. Patients received either a single-shot ultrasound-guided subcostal transversus abdominis plane (TAP) block with 0.19% ropivacaine or conventional fentanyl-based IV-PCA. Postoperative analgesic requirements, functional recovery outcomes, and safety profiles were evaluated. Results: All patients in the Group TAP (n = 60) required no rescue analgesia during the first 12 postoperative hours and did not require nonsteroidal anti-inflammatory drugs or IV-PCA within 24 h. Early recovery milestones were consistently achieved, including preserved early ambulation, prompt tolerance of oral intake, and smooth transition to oral acetaminophen 650 mg orally three times daily from postoperative day 1. All Group TAP patients met the discharge criteria by postoperative day 2 without opioid-related adverse events or signs of local anesthetic systemic toxicity. In contrast, the Group IV-PCA (n = 60) exhibited a high incidence of opioid-related adverse effects, frequent PCA interruption or discontinuation, delayed functional recovery, and prolonged hospitalization. Conclusions: A single-shot ultrasound-guided subcostal TAP block using low-concentration ropivacaine can function as a reliable, opioid-free primary analgesic strategy after laparoscopic cholecystectomy, effectively supporting ERAS-consistent early recovery. This approach represents a practical and clinically meaningful alternative to conventional IV-PCA in routine LC.<\/jats:p>","DOI":"10.3390\/jcm15031120","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T09:00:33Z","timestamp":1770022833000},"page":"1120","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Single-Shot Ultrasound-Guided Transversus Abdominis Plane Block Versus Intravenous Patient-Controlled Analgesia for Early Recovery After Laparoscopic Cholecystectomy: A Retrospective Cohort Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1015-4722","authenticated-orcid":false,"given":"Youngjoo","family":"Park","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Samsung Changwon Hospital, College of Medicine, Sungkyunkwan University, Changwon 51353, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1001\/jamasurg.2016.4952","article-title":"Enhanced recovery after surgery: A review","volume":"152","author":"Ljungqvist","year":"2017","journal-title":"JAMA Surg."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"96","DOI":"10.1016\/j.jpedsurg.2019.09.053","article-title":"ERAS protocol for pediatric laparoscopic cholecystectomy promotes safe and early discharge","volume":"55","author":"Yeh","year":"2020","journal-title":"J.
