    Abstract:
    BACKGROUND: The coeliac plexus is often approached due to the diagnosis and treatment of the intractable pain associated with cancerous or non-cancerous pathology of the pancreas or neighbouring organs. Various methods of coeliac plexus blocks are used and the variations in its structure are causes of the failures of such procedures. METHODS: Twenty human cadavers (17 male, 3 females, age range 30-86 years, without any abdominal pathology) were dissected in the supine position. The abdominal autonomics was studied bilaterally after the incision of the abdominal wall the peritoneal sac was cut and the abdominal organs were removed. The coeliac plexus becomes visible after removing the hepatogastric and hepatoduodenal ligaments and pulling the stomach to the left and the pancreas downward. RESULTS: The largest coeliac ganglion was 45 mm on the right and 25 mm on the left. The average distance of the ganglia from the coeliac trunks was 6-9 mm from the right and left. The size of coeliac ganglia varies from 5 to 45 mm and their number from 2 to 12. Ganglia can be diffusely or concentrically organized. The coeliac plexus almost always receives the branches from the greater splanchnic and vagus nerves. Sometimes the contributions from the lesser splanchnic nerve, phrenic nerve, and accessory phrenic nerve (60%) were observed. Very rarely are missing both phrenic nerves. CONCLUSION: Sympathectomy (splanchnicectomy), as well as the coeliac blocks (under US, CT control, or laparotomic) aimed at pain relief usually by pancreatic cancer, should consider these possible variabilities.
