[Clinical observation of CT guided two needles puncturing crossed through disc for superior hypogastric block to manage intractable pelvic cancer pain].

OBJECTIVE: To observe the feasibility and clinical efficacy of CT guided two needles puncturing crossed through disc for superior hypogastric block with alcohol to manage intractable pelvic cancer pain. METHODS: Thirty-one cases of advanced pelvic cancer suffering from untreatable pain in lower abdomen in our hospital from December 2009 to May 2012 were analyzed, the patients were treated with both sides of superior hypogastric block with absolute alcohol by CT guided two needles puncturing crossed through L5-S1 interlaminar space. Complications during and after the surgery were recorded. To observe and follow-up visual analog scale pain scores (VAS) and the daily oral morphine consumption on just before operation, at 1 week, 1 and 3 months after operation. RESULTS: No case suffered serious complication. A week later of surgery the curative effect of 20 patients: clinical cure in 17 cases, excellent in 14 cases, the effective rate was 100%. Compared with preoperation, The score of VAS on 1 week, 1 and 3 months after the surgery (2.0±0.7, 2.3±0.6, 3.0±0.4) were strikingly lower than before operation (7.7±0.7, P < 0.01); The daily oral dose of morphine of post-operation were significantly decreased in the three time points ((35±17) mg, (42±22) mg and (53±19) mg respectively) than the dose of pre-operation ((201±119)mg, P < 0.01). CONCLUSION: Superior hypogastric block with alcohol with double needles crossed transdiscal approach may be a safe, simple and effective method for relieving the severe pain of advanced pelvic cancer patients.
