Superior hypogastric block: transdiscal versus classic posterior approach in pelvic cancer pain

Abstract

Objective: The classic posterior approach of superior hypogastric block has several technical difficulties. The transdiscal approach is a novel and easier approach for superior hypogastric which overcome these technical difficulties.

Methods: Thirty patients were randomly allocated to two groups: The transdiscal group and the classic group; visual analog scale pain scores, daily morphine consumption, duration of the procedure and side effects were recorded.

Results: The duration of the procedure was significantly decreased in the transdiscal group (24.4+/-5.6 min) compared to the classic group (57.9+/-9.8 min). There were no significant differences between the 2 groups in daily morphine consumption and VAS pain scores. There was no discitis, disc rupture, or herniation in the transdiscal group.

Conclusion: The transdiscal approach for superior hypogastric plexus block in pelvic cancer pain is easier, safer, and more effective with less side effects than the classic approach.
