Intraoperative Continuous Terlipressin Infusion is Associated With Reduced Severe Postoperative Complications After Laparoscopic Hepatectomy: a Prospective Propensity Score-matched Cohort Study

Liver resection is an important surgical procedure for the treatment of patients with various liver diseases. Although advances in surgical techniques and perioperative management have improved outcomes, postoperative complications remain a significant concern after major abdominal surgery. Perioperative hemodynamic management plays an important role in maintaining adequate organ perfusion and may influence postoperative recovery. Terlipressin is a vasoactive medication that increases vascular tone and may help maintain hemodynamic stability during surgery. In clinical practice, terlipressin may be administered during surgery based on the judgment of the attending anesthesiologist. However, the association between intraoperative continuous terlipressin infusion and postoperative outcomes in patients undergoing laparoscopic hepatectomy remains unclear. This prospective observational cohort study was designed to evaluate the association between continuous intraoperative terlipressin infusion and postoperative severe complications in patients undergoing laparoscopic hepatectomy. Patients undergoing laparoscopic hepatectomy will be prospectively enrolled according to predefined eligibility criteria and followed according to the study protocol. Clinical characteristics, perioperative management information, intraoperative terlipressin exposure, and postoperative outcomes will be collected prospectively. The primary objective of this study is to assess whether intraoperative continuous terlipressin infusion is associated with the incidence of severe postoperative complications after laparoscopic hepatectomy.
