While stellate ganglion block (SGB) is increasingly utilized for acute and chronic pain management, limited evidence exists regarding its efficacy in modulating visceral pain after gynecologic laparoscopy. This study aimed to evaluate whether ultrasound-guided SGB could reduce early postoperative visceral pain intensity and opioid consumption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this prospective, randomized controlled trial, 90 patients undergoing laparoscopic hysterectomy were allocated (1:1:1) to receive ultrasound-guided SGB combined with transversus abdominis plane block (TAPB) (SGB group), TAPB alone (TAP group), or no nerve block (control group). The primary outcome was visceral pain intensity, assessed using visual analog scale (VAS) scores at rest and during movement at 1, 3, 6, 24, and 48 hours postoperatively. Secondary outcomes included rescue analgesia requirements and complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The linear mixed-effects model revealed that the SGB group exhibited a significantly greater reduction in visceral pain intensity at rest and during movement at 1, 3, and 6 hours compared to the TAP and control groups (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.05).
