title: CT-guided microinvasive intervention in treating refractory carcinous pain.
abstract: OBJECTIVE
  To evaluate the analgesic effect of CT-guided microinvasive intervention on refractory carcinous pain.
  
  
  METHODS
  A total of 23 patients with poor response to drug therapy for carcinous pain were selected: 6 patients underwent CT-guided neurolytic celiac plexus block (NCPB), 5 patients underwent CT-guided(125)I implantation and 12 patients underwent combined CT-guided NCPB and CT-guided(125)I implantation.
  
  
  RESULTS
  After 1 week of treatment, 6 patients exhibited complete remission, 13 patients exhibited partial remission and 4 patients exhibited no changes in condition. The treatment efficiency rate was 82.6%. After 1 month of treatment, 5 patients exhibited complete remission, 14 patients exhibited partial remission and 4 patients exhibited no changes in condition. Treatment efficiency rate was 82.6%. After 3 months of treatment, 4 patients exhibited complete remission, 9 patients exhibited partial remission, 5 patients exhibited no changes in condition and 5 patients died. Treatment efficiency rate was 72.2%. After 6 months of treatment, 3 patients exhibited complete remission, 6 patients exhibited partial remission, 3 patients exhibited no changes in condition and 11 patients died. The treatment efficiency rate was 75.0%. No severe postoperative severe complications, such as bleeding, biliary fistula and pancreatic fistula, were reported.
  
  
  CONCLUSIONS
  CT-guided microinvasive intervention clearly demonstrated an analgesic effect on refractory carcinous pain with less trauma and few complications. Therefore, this method provides effective relief for carcinous pain.
