Rectovaginal septum

Rectovaginal Septum

The rectovaginal septum is an important anatomical structure in the female pelvis, serving as a divider between the rectum and the vagina. This fibromuscular tissue is crucial for the structural integrity and function of the pelvic floor, playing a significant role in the overall health and reproductive system of women.

Anatomy

The rectovaginal septum is located between the posterior wall of the vagina and the anterior wall of the rectum. It is composed of connective tissue and smooth muscle fibers, contributing to its strength and flexibility. The thickness and composition of the septum can vary among individuals. It is part of the endopelvic fascia, which supports the pelvic organs and contributes to the maintenance of continence.

Function

The primary function of the rectovaginal septum is to separate the rectum from the vagina, thereby maintaining the structural integrity of the pelvic floor. It also plays a role in sexual health and childbirth. During vaginal delivery, the flexibility of the rectovaginal septum allows for the passage of the baby while minimizing damage to the pelvic structures.

Clinical Significance

The integrity of the rectovaginal septum is crucial for pelvic health. Damage or weakening of this structure can lead to conditions such as rectocele, where the wall of the rectum bulges into the vagina, or dyspareunia, painful sexual intercourse. Conditions affecting the rectovaginal septum can arise from childbirth, surgery, aging, or other factors that stress the pelvic floor.

Diagnosis and Treatment

Diagnosis of conditions related to the rectovaginal septum typically involves a physical examination, imaging studies such as ultrasound or MRI, and sometimes endoscopic procedures. Treatment options vary depending on the condition but may include physical therapy, pessary devices, or surgery to repair or reinforce the septum.

Surgical Considerations

Surgery involving the rectovaginal septum requires careful consideration due to the close proximity of the rectum and vagina and the potential for complications. Procedures may be performed for the repair of a rectocele, to remove endometriosis involving the septum, or for the treatment of certain types of pelvic tumors.
