A case of intractable chronic abdominal pain caused by hepatomegaly associated with primary amyloidosis, successfully treated with celiac plexus block]

A 51-year-old female previously diagnosed as primary amyloidosis suffered from recurrent abdominal pain. The result of thorough examination indicated that the main cause of the pain was severe hepatomegaly. Continuous venous administration of narcotics and other alternative therapies did not provide symptomatic relief, and thus the patient was treated with celiac plexus block, which resulted in effective pain control and improved ADL level. Though the procedure of celiac plexus block is simple and celiac plexus block is applicable without causing severe complication, it is not widely used. From this case, it is considered that celiac plexus block is one of the most effective means to relieve intractable pain associated with both benign malady and abdominal malignant tumor.
