Low Volume Neurolytic Retrocrural Celiac Plexus Block for Visceral Cancer Pain: Retrospective Review of 507 Patients with Severe Malignancy Related Pain Due to Primary Abdominal Cancer or Metastatic Disease.

Background: Abdominal pain from primary cancer or metastatic disease is a significant cause of pain for patients undergoing treatment for the disease. Patient's pain may be resistant to conventional analgesics. The need for timely pain relief in order to facilitate further care in the cancer treatment plan should be a priority.
