To evaluate the safety and efficacy of direct celiac ganglion irradiation with 125I seeds for the relief of moderate to severe pain secondary to unresectable PC.
Prospective study.
Single, tertiary care referral center.
This study enrolled consecutive patients who had moderate to severe pain resulting from biopsy-proven unresectable PC.
All patients underwent EUS-guided direct celiac ganglion irradiation with 125I seeds. Follow-up was conducted at least once weekly until death.
Blood parameters, Visual Analog Scale (VAS) score, mean analgesic (MS Contin [morphine sulfate]) consumption, and complications were evaluated during follow-up.
Twenty-three patients with unresectable PC underwent the procedure. The mean number of seeds implanted in the celiac ganglion per patient was 4 (range 2-6). Immediately after the procedure, pain relief and analgesic consumption showed no significant changes compared with preoperative values. Six patients (26 % ) reported pain exacerbation. Two weeks later, the VAS score and mean analgesic consumption were significantly less than preoperative values. No procedure-related deaths or major complications occurred.
Uncontrolled study.
EUS-guided direct celiac ganglion irradiation with 125I seeds can reduce the VAS score and analgesic drug consumption in patients with unresectable PC.
