Second shot could slash opioid use after major cancer surgery

This study is testing if giving a second numbing injection a few days after major abdominal cancer surgery helps patients manage pain with fewer opioid painkillers. It compares a single injection to a repeat injection in patients having surgery for a type of abdominal tumor called retroperitoneal sarcoma. The main goal is to see if the repeat injection helps more patients leave the hospital without needing an opioid prescription, aiming to reduce long-term use and addiction risk.
