Abdominal plexus destruction is suitable for the destruction of visceral nerves located in the upper abdomen, mainly for pain caused by pancreatic cancer, gastric cancer, liver cancer and abdominal lymph node metastasis stimulating the compression of abdominal plexus, and is most effective when the pain has just appeared in the early stage without serious metastasis of the posterior peritoneum. Destruction of the abdominal plexus is usually performed by puncture and localization under CT or C-arm imaging interventions, and the correct location is confirmed by injecting nerve-destroying drugs so as to achieve prolonged pain relief, which usually has no other adverse effects except for a short period of hyperactive bowel movements.
