pouch of Douglas obliteration
Complete or partial closure of the rectovesical pouch, often due to endometriosis or adhesive disease.
Full Definition
Pouch of Douglas obliteration refers to the complete or partial closure of the rectovesical pouch (pouch of Douglas), the most dependent part of the female peritoneal cavity located between the posterior uterus and anterior rectum. This condition is most commonly caused by severe endometriosis, but can also result from pelvic inflammatory disease, previous surgery, or malignancy. Obliteration can be partial or complete and significantly impacts surgical approaches, particularly during hysterectomy or endometriosis treatment. Diagnosis is typically made through imaging studies such as MRI or transvaginal ultrasound, and surgical management often requires complex dissection techniques to restore normal anatomy.
Usage
Usage note: May be abbreviated as POD obliteration; important for surgical planning documentation.
