Superior hypogastric block during microlaparoscopic pain mapping.

Pelvic pain mapping during laparoscopy performed under conscious sedation can provide useful information about visceral and somatic sources of chronic pelvic pain. Diagnostic superior hypogastric plexus block can be performed under direct laparoscopic visualization and the pelvis then remapped to determine if painful areas are supplied by hypogastric plexuses. Results of mapping may allow more informed selection of patients for presacral neurectomy.
