Comparison of Paragastric Nerve Block and Erector Spinae Plane Block on Postoperative Pain After Sleeve Gastrectomy
A Prospective Randomized Controlled Trial Comparing the Effects of Paragastric Nerve Block and Erector Spinae Plane Block on Postoperative Pain Management Following Laparoscopic Sleeve Gastrectomy

Brief summary (registry, in English)
Background: Laparoscopic sleeve gastrectomy is one of the most commonly performed bariatric procedures for the treatment of obesity. Despite its minimally invasive nature, patients frequently experience moderate to severe postoperative pain, which may delay mobilization, prolong hospital stay, increase opioid consumption, and reduce patient satisfaction. Effective postoperative pain management is therefore an important component of perioperative care. Regional analgesia techniques are increasingly used as part of multimodal analgesia protocols to reduce opioid requirements and opioid-related adverse effects. Paragastric nerve block (PGNB) has been reported to provide effective control of visceral pain, nausea, and vomiting after sleeve gastrectomy. Erector spinae plane block (ESPB) is another regional anesthesia technique that has demonstrated efficacy in reducing perioperative opioid consumption in bariatric surgery patients. However, no prospective randomized study has directly compared PGNB and ESPB in patients undergoing sleeve gastrectomy. This prospective, randomized, controlled clinical trial aims to compare the effects of PGNB, ESPB, and standard analgesia on postoperative pain management following laparoscopic sleeve gastrectomy. Seventy-two adult patients scheduled for elective sleeve gastrectomy will be randomized in a 1:1:1 ratio to receive PGNB, ESPB, or standard multimodal analgesia alone. The primary outcome will be postoperative pain intensity measured using the Visual Analog Scale (VAS) at 1, 6, 12, and 24 hours after surgery. Secondary outcomes include postoperative opioid consumption, intraoperative remifentanil consumption, additional analgesic requirements, time to first analgesic request, postoperative nausea and vomiting, and block-related complications.
