The Efficacy and Safety of Liposomal Bupivacaine in Relieving Postoperative Pain After Hemorrhoid Surgery

Hemorrhoids represents the most prevalent condition among anorectal disorders. Due to the unique anatomical characteristics of the perianal region, patients frequently experience severe postoperative pain, which may lead some individuals to delay treatment due to pain-related anxiety. Consequently, effective postoperative pain management is critical for the recovery of hemorrhoid patients. Developing a simplified, efficient, and safe analgesic approach to alleviate postoperative pain has become an urgent issue in perioperative care. Multimodal analgesia regimens recommend the combined use of local anesthetics to synergistically reduce perioperative pain intensity. However, the primary limitation of this analgesic modality lies in the relatively short duration of action following a single injection of local anesthetic.Liposomal bupivacaine is an innovative long-acting, extended-release amide-type local anesthetic that provides analgesic efficacy for up to 72 hours. However, its efficacy and safety for local infiltration analgesia following hemorrhoid surgery have not been fully validated. Against this backdrop, the present study aims to evaluate and compare the clinical outcomes and safety profile of liposomal bupivacaine versus conventional bupivacaine for postoperative pain management via local infiltration in patients undergoing Hemorrhoid surgery.
