This is a phase 4, prospective, sequential, open-label study designed to evaluate the efficacy, safety, and health economic benefits of intraoperative local wound infiltration with EXPAREL (bupivacaine liposome extended-release injectable suspension), compared with postsurgical administration of standardized intravenous (IV) morphine sulfate, for postsurgical analgesia in adult patients undergoing open colectomy with general anesthesia.
