    BackgroundEthanol celiac plexus neurolysis (ECPN) has been shown to be effective in reducing cancer-related pain in patients with locally advanced pancreatic and periampullary adenocarcinoma (PPA). This study examined its efficacy in patients undergoing PPA resection.Study DesignThere were 485 patients who participated in this prospective, randomized, double-blind placebo controlled trial. Patients were stratified by preoperative pain and disease resectability. They received either ECPN (50% ethanol) or 0.9% normal saline placebo control. The primary endpoint was short- and long-term pain and secondary endpoints included postoperative morbidity, quality of life, and overall survival.ResultsData from 467 patients were analyzed. The primary endpoint, the percentage of PPA patients experiencing a worsening of pain compared with preoperative baseline for resectable patients, was not different between the ethanol and saline groups in either the resectable/pain stratum (22% vs 18%, relative risk [RR] 1.23 [0.34, 4.46]), or the resectable/no pain stratum (37% vs 34%, RR 1.10 [0.67, 1.81]). In multivariable analysis of resected pancreatic ductal adenocarcinoma (PDA) patients, there was a significant reduction in pain in the resectable/pain group, suggesting that surgical resection of the malignancy alone (independent of ECPN) decreases pain to a significant degree.ConclusionsIn this study, we demonstrated a significant reduction in pain after surgical resection of PPA. However, the addition of ECPN did not synergize to result in a further reduction in pain, and in fact, its effect may have been masked by surgical resection. Given this, we cannot recommend the use of ECPN to mitigate cancer-related pain in resectable PPA patients.Copyright © 2015 American College of Surgeons. Published by Elsevier Inc.
