Ultrasound guidance technique in celiac plexus block

The aim of our study was to describe the technique and the efficacy of ultrasound-guidance for celiac plexus block in cancer patients in our institution Antoine Lacassagne Center. Celiac plexus block was performed in 13 cancer patients under ultrasound-guidance (n=13). All patients had excruciating epigastric and generalized abdominal pain caused by cancer. Feasibility and complication rates were analyzed. Notable pain relief was obtained in 9/13 (69%) of the patients and the technical success rate was 93% (12/13). There were 2 minor complications : orthostatic arterial hypotension (n=1) and transient left shoulder pain (n=1). Color Doppler sonography improved visualization of the 21 Gauge Chiba needle when the needle shaft was vibrated. Echogenic foci were observed around the origin of the celiac trunk and superior mesenteric artery in all cases. Ultrasound guidance is safe and effective and should be attempted for celiac plexus block whenever possible.
