Coeliac plexus block using computed tomography guidance

Coeliac plexus blocks have been used successfully in the treatment of abdominal pain in advanced cancer and in benign chronic abdominal pain. However, concern remains about occasional potentially serious complications. One possible way to reduce the risks of this procedure may be to improve imaging during the procedure. We report a series of 38 coeliac plexus blocks carried out under computer tomographic (CT) guidance, mostly using the anterior approach. The technique is described. Effectiveness and side-effect rates were similar to other reported series. There were no major complications. Analysis of contrast spread would indicate that anterior preaortic or bilateral contrast spread is necessary to obtain pain relief. Our experience would indicate that routine CT guidance can be a simple aid to coeliac plexus block, and can be achieved easily in a district general hospital. Improved imaging allows accurate needle placement, while avoiding vital structures such as the aorta and pleura. Accurate placement may also allow the use of reduced volumes of neurolytic drugs.
