Coeliac plexus block for chronic pain syndromes.

The purpose of this article is to familiarize the anaesthetist with the basic anatomy of the coeliac plexus; the techniques used to perform the procedure, its indications, complications and results in the management of chronic abdominal pain syndromes. Radiological, surgical and anaesthetic literature from the beginning of the century were reviewed. The main indication for neurolytic coeliac plexus block is intractable pain secondary to carcinoma of the pancreas or stomach. There appear to be theoretical advantages to techniques that result in spread of solution anterior to the aorta, such as the trans-aortic approach. These have not yet been demonstrated in any studies with large numbers of patients.
