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.
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.
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.
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.
