Ultrasound-guided alcoholization of celiac plexus for pain control in oncology.

BACKGROUND: Treatment of inoperable pancreatic cancer pain is of paramount importance. The ineffectiveness of pharmacological agents has led many investigators to recommend chemical neurolysis of the celiac ganglions for pain control. This procedure may be performed under either fluoroscopic or computed tomography (CT) guidance, or it may accompany laparotomy. The authors describe a modified sonographically (ultrasound-US)-guided technique for alcoholization of the celiac ganglions. METHODS: Twelve patients underwent the neurolytic procedure. Nine of 12 suffered from pancreatic cancer. The remaining three were affected by inoperable hepatic, gastric, or colon cancer, respectively, with multiple hepatic metastases. US-guided alcohol neurolysis was performed by an anterior approach. In the last four patients, PIA (percutaneous injection alcohol) needles, modified by the authors, replaced the spinal needles employed in the first eight patients to inject the alcohol. Pain and pain relief were rated according to a Simple Descriptive Scale (SDS), and treatment success was gauged by declining opiate doses and need for pharmacological therapy. Results after treatment performed using different needles were compared. RESULTS: Procedure-related mortality was zero. Complications of the neurolytic procedure included left pleural effusion in one patient and mild diarrhea in two other patients. Positive, negative, and indeterminant results were noted in nine (75%, p < 0.001), two, and one patient(s), respectively. CONCLUSIONS: The neurolytic technique, although far from being considered a routine procedure, appears to provide patients with safe and effective pain relief for pain unresponsive to conventional medical treatment.
