Introduction: Minimally invasive surgery (MIS) has been associated with diminished postoperative pain and analgesia requirements. The objective of the current study was to evaluate the use of analgesia in the post-operative period following robotic surgery for endometrial cancer.
Methods: All consecutive patients who underwent robotic surgery for the treatment of endometrial cancer were included in this study. The timing, dose, and type of analgesics administered postoperatively were recorded from patients' electronic medical record. Data was compared to a matched historical cohort of patients who underwent laparotomy before the introduction of the robotic program.
Results: Only eight patients (2.4%, 5 during the first 25 cases and 3 following mini-laparotomy) received patient-controlled analgesia (PCA) following robotic surgery. Most patients' pain was alleviated by over-the-counter analgesics (acetaminophen, non-steroidal anti-inflammatories). In comparison to laparotomy, patients who underwent robotic surgery required significantly less opioids (71mg vs. 12mg IV morphine, p<0.0001) and non-opioids (4810mg vs. 2151mg acetaminophen, 1892 vs. 377mg ibuprofen, and 1470mg vs. 393mg naproxen; all p<0.0001).
Conclusion: Patients require less analgesics (opioids and non-opioids) following robotic surgery in comparison to conventional laparotomy, including the elderly and the obese. The diminished pain medication use is associated with some cost savings.
