Combined neurolytic block of celiac and superior hypogastric plexuses for incapacitating upper abdominal cancer pain.

PURPOSE: To evaluate the efficacy of a combined neurolytic block of the celiac and superior hypogastric plexuses for incapacitating upper abdominal cancer pain.

METHODS

Fifty-two patients with advanced upper abdominal malignancies and incapacitating pain were equally randomized to receive a combined neurolytic block of the celiac and superior hypogastric plexuses (combined group) or a neurolytic celiac plexus block alone (NCPB group) using a 90% ethanol trans-intervertebral disk approach under CT guidance. Visual analogue scores (VAS), morphine consumption, and quality of life (QoL) were assessed before the procedure and 24 hrs, 1 week, 1 month, and 3 months after the procedure. The complications and side effects were also recorded.

RESULTS

The amount of ethanol used was 30 ± 5 ml in the combined group and 21 ± 3 ml in the NCPB group. VAS scores and morphine consumption decreased significantly pre- compared to post-procedure in both groups (p<0.05). QoL significantly improved 24 hrs, 1 week, and 1 month after the procedure compared with each group pre-procedure (p<0.05), but not after 3 months (p>0.05). The combined group had significantly lower VAS and morphine consumption than the NCPB group (p<0.05). QoL scores were significantly higher in the combined group 24 hrs, 1 week, and 1 month post-procedure than the NCPB group (p<0.05), but not after 3 months (p>0.05).

CONCLUSION

A combined neurolytic block of the celiac and superior hypogastric plexuses is more effective than neurolytic celiac plexus block alone in pain relief for patients with advanced upper abdominal cancer.
