Rectocele: A rectocele is a bulge of the front wall of the rectum into the vagina. Normally, the rectum goes straight down to the anus (picture). When a patient with a rectocele strains, the stool may get caught in an abnormal pocket of the rectum which bulges into the vagina. This prevents the patient from emptying the rectum completely. Generally, rectoceles do not produce symptoms. As they grow larger, rectoceles may cause difficulty going to the bathroom, or cause leakage of stool after having a bowel movement. Rectoceles are more common in women who have given birth. Rectoceles are usually caused by thinning of the tissue between the rectum and vagina and weakening of the pelvic floor muscles.
There are various procedures used to address prolapse. Cystoceles are treated with a surgical procedure known as a Burch colposuspension, with the goal of suspending the prolapsed urethra so that the urethrovesical junction and proximal urethra are replaced in the pelvic cavity. Uteroceles are treated with hysterectomy and uterosacral suspension. With enteroceles, the prolapsed small bowel is elevated into the pelvis cavity and the rectovaginal fascia is reapproximated. Rectoceles, in which the anterior wall of the rectum protrudes into the posterior wall of the vagina, require posterior colporrhaphy.
Biofeedback: This is the most common treatment, done with the help of a physical therapist. Biofeedback is not painful, and helps over 75% of people with pelvic floor dysfunction. Your physical therapist might use biofeedback in different ways to retrain your muscles. For example, they may use special sensors and video to monitor the pelvic floor muscles as you try to relax or clench them. Your therapist then gives you feedback and works with you to improve your muscle coordination.
Pelvic floor dysfunction can be diagnosed by history and physical exam, though it is more accurately graded by imaging. Historically, fluoroscopy with defecography and cystography were used, though modern imaging allows the usage of MRI to complement and sometimes replace fluoroscopic assessment of the disorder, allowing for less radiation exposure and increased patient comfort, though an enema is required the evening before the procedure. Instead of contrast, ultrasound gel is used during the procedure with MRI. Both methods assess the pelvic floor at rest and maximum strain using coronal and sagittal views. When grading individual organ prolapse, the rectum, bladder and uterus are individually assessed, with prolapse of the rectum referred to as a rectocele, bladder prolapse through the anterior vaginal wall a cystocele, and small bowel an enterocele.
A defecating proctogram is a test where you’re given an enema of a thick liquid that can be seen with an X-ray. Your provider will use a special video X-ray to record the movement of your muscles as you attempt to push the liquid out of the rectum. This will help to show how well you are able to pass a bowel movement or any other causes for pelvic floor dysfunction. This test is not painful.
