Background: Efforts for improving surgical outcomes in elderly patients should include the prevention of perioperative complications and proper postoperative pain management. Epidural analgesia is effective in decreasing perioperative stress and postoperative complications, and in improving recovery. Recently, it has been suggested that epidural analgesia may attenuate immune suppression during the perioperative period and lead to reductions in cancer recurrence and improvements in overall survival. Assuming that these effects of epidural analgesia are present in vulnerable elderly patients, we compared the efficacy of epidural patient-controlled analgesia and intravenous patient-controlled analgesia on postoperative outcomes in elderly patients who had undergone gastrectomy.
Methods: We evaluated 214 elderly patients who had undergone elective open gastrectomy for gastric cancer from 2011 to 2014. The demographic characteristics, analgesic efficacy, complications within the first 30 postoperative days, hospital stay, 24-month postoperative morbidity, cancer recurrence, and mortality were studied retrospectively.
Results: Two-hundred and five patients were analyzed. Eighty-five patients received epidural patient-controlled analgesia (EPCA group) and 120 patients received intravenous patient- controlled analgesia (IVPCA group). The maximum pain scores were decreased to a greater extent in the EPCA group on the day of the operation (P < 0.001) and on the first postoperative day (P = 0.001) when compared to the IVPCA group. The patients in the EPCA group also required less analgesics on the day of the operation (P = 0.033) than those in the IVPCA group. The effect of EPCA on complications within the first 30 postoperative days, 24-month postoperative morbidity, cancer recurrence, and mortality were negligible in our study.
Conclusions: EPCA provided more effective pain control than IVPCA in elderly patients who had undergone elective gastric cancer surgery, but did not affect postoperative outcomes.
