Randomized Controlled Trial
Efficacy of the anterior ultrasound-guided superior hypogastric plexus neurolysis in pelvic cancer pain in advanced gynecological cancer patients.
Pelvic cancer pain is a chronic pain related to the involvement of viscera, neural, and pelvic muscular. The study was carried out to evaluate the efficacy of anterior ultrasound-guided superior hypogastric plexus neurolysis in pelvic cancer pain in gynecological cancer patients. ⋯ The anterior USG-guided superior hypogastric plexus neurolysis is a useful technique in relieving pelvic pain in gynecological malignancies. However, it requires expertise to perform the block. It also avoids the radiation exposure involved with computed tomography-guided and fluoroscopy-guided superior hypogastric block.

To test the null hypotheses that: lumbar intervertebral discs cannot be a source of pain; discs are not a source of pain; painful lumbar discs cannot be diagnosed; and there is no pathology that causes discogenic pain. ⋯ All of the null hypotheses that have been raised against the concept of discogenic pain and its diagnosis have each been refuted by one or more studies. Although studies have raised concerns, none has sustained any null hypothesis. Discogenic pain can occur and can be diagnosed if strict operational criteria are used to reduce the likelihood of false-positive results.
