Summary

Pelvic pain mapping during laparoscopy under conscious sedation helps identify pain sources. Diagnostic blocks can confirm if pain originates from the hypogastric plexus, guiding treatment like presacral neurectomy.

Area of Science:

  • Minimally invasive gynecological surgery
  • Pain management strategies
  • Neuroanatomy of pelvic pain

Background:

  • Chronic pelvic pain (CPP) affects many women, often with unclear origins.
  • Laparoscopy under conscious sedation allows patient interaction during diagnostic procedures.
  • The superior hypogastric plexus (SHP) is a key nerve structure involved in pelvic visceral sensation.

Observation:

  • Pelvic pain mapping during laparoscopy can differentiate visceral from somatic pain sources.
  • Direct laparoscopic visualization enables precise placement of diagnostic SHP blocks.
  • Remapping the pelvis after the block assesses the SHP's contribution to pain.

Findings:

  • SHP blocks effectively identify the nerve plexus's role in CPP.

Related Experiment Videos

  • Pain mapping combined with diagnostic blocks provides objective data on pain pathways.
  • This diagnostic approach can guide patient selection for surgical interventions.

    • Implications:

    • Informed patient selection for presacral neurectomy, a surgical treatment for CPP.
    • Improved understanding of neuroanatomical pain generators in the pelvis.
    • Potential for more targeted and effective management of refractory chronic pelvic pain.
