BackgroundPostoperative pain following video-assisted thoracoscopic surgery (VATS) remains a significant challenge. While epidural analgesia is still the gold standard, other types of regional analgesia are gaining popularity because of perceived less risk of complications. The efficacy of systemic opioids as an alternative to epidural analgesia has not been thoroughly explored. This systematic review and meta-analysis aims to evaluate and compare the efficacy of systemic opioids versus epidural analgesia in managing postoperative pain after VATS.MethodsWe will conduct a systematic review and meta-analysis in accordance with the Cochrane Handbook and the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) checklist. A comprehensive search will be conducted in MEDLINE, EMBASE, and the Cochrane Library supplemented with Scopus citation searches, search for gray literature using Google Scholar and a search for ongoing studies. We will include studies based on the PICO methodology without restrictions regarding study type. Two independent reviewers will screen studies, extract data, and assess study quality using the Cochrane Risk of Bias tools. The primary outcomes will be postoperative pain intensity at rest and during activity at 24, 48, and 72 h. Secondary outcomes will include use of "rescue" opioids, hospital length of stay, and adverse events. If feasible, a meta-analysis will be done, otherwise we will perform a descriptive analysis.ResultsThe results will provide a comparative analysis of the effectiveness of systemic opioids versus epidural analgesia in managing postoperative pain in VATS patients. Data synthesis will include pooled estimates for pain scores, opioid consumption, and adverse events, possibly with subgroup and sensitivity analyses conducted to explore heterogeneity across studies.ConclusionsThis systematic review will offer valuable insights into the optimal pain management strategy for patients undergoing VATS. The findings may guide clinical practice in selecting the most effective and safe analgesic approach, improving postoperative recovery, and patient outcomes.© 2024 The Author(s).
