Comparison of Neurolytic Block Techniques for the Treatment of Abdominal Visceral Pain and Their Influence On The Quality of Life of Patients With Cancer
The neurolytic blocks of sympathetic chains are commonly used for the treatment of cancer-related pain. This study aims to compare celiac plexus neurolysis and splanchnic nerve neurolysis for the treatment of abdominal visceral pain and its influence on the quality of life of patients with cancer.
