Repeat Quadratus Lumborum Block to Reduce Opioid Need in Patients After Pancreatic Surgery

PRIMARY OBJECTIVE: I. To use a phase II randomized controlled trial to compare the intervention of a second regional anesthetic block (quadratus lumborum \[QL\] block) versus usual care (single intraoperative QL block) to increase the proportion of opioid-free pancreatic cancer survivors at discharge after potentially curative surgery. OUTLINE: Patients are randomized to 1 of 2 arms. ARM 1: Patients undergo QL block before surgery and receive standard of care multimodal pain control after surgery. ARM 2: Patients undergo QL block before surgery and receive multimodal pain control. Patients then undergo a second QL block on day 4 after surgery and continue to receive standard of care. After completion of study treatment, patients are followed up at 1 month, 3 months, 6 months, and 1 year after surgery.
