BACKGROUND: The technique of alcohol injection during EUS-guided celiac plexus neurolysis (CPN) in patients with pancreatic cancer-related pain has not been standardized. OBJECTIVE: To compare pain relief and safety of alcohol given as 1 versus 2 injections during EUS-guided CPN (EUS-CPN). Secondary outcomes examined were characteristics that predict response and survival. DESIGN: Single-blinded, prospective, randomized, parallel-group study. SETTING: Tertiary-care center. PATIENTS: This study involved patients with pancreatic cancer-related pain. INTERVENTION: EUS-CPN done by injecting 20 mL of 0.75% bupivacaine and 10 mL 98% alcohol into 1 or 2 sites at the celiac trunk. Participants were interviewed by telephone at 24 hours and weekly thereafter. MAIN OUTCOME MEASUREMENTS: Time until onset of pain relief, duration of pain relief, complications. RESULTS:Fifty patients (mean age 63 years; 24 men) were enrolled and randomized (29 in 1-injection, 21 in 2-injections groups). Pain relief was observed in 37 (74%) patients: 20 (69%) in the 1-injection group and 17 (81%) in the 2-injection group (chi-square P = .340). Median onset of pain relief was 1 day for both 1-injection (range 1-28 days) and 2-injection (range 1-21 days) groups (Mann-Whitney P = .943). Median duration of pain relief in the 1-injection and 2-injection groups was 11 weeks and 14 weeks, respectively (log-rank P = .612). Complete pain relief was observed in 4 (8%) patients total, 2 in each group. There were no long-term complications. LIMITATIONS: Single-blinded study. CONCLUSION: There were no differences in onset or duration of pain relief when either 1 or 2 injections were used. There was no difference in safety or survival between the 2 groups.
