pouch of Douglas
Anatomical space between the rectum and posterior uterus where malignant cells commonly implant.
Full Definition
The rectouterine pouch, also known as the pouch of Douglas, is the most dependent part of the peritoneal cavity in the upright position, located between the posterior aspect of the uterus and the anterior wall of the rectum. In gynecologic oncology, this space is clinically significant as it is a common site for peritoneal implants and metastatic deposits due to gravitational pooling of malignant cells. Assessment of this area is crucial during staging procedures and surgical planning.
Usage
Usage note: Capitalize 'Douglas' as it is an eponym derived from anatomist James Douglas.
