Understanding Rectocele

What is a rectocele?

A rectocele is an outpouching of the anterior wall of the rectum through a weakened rectovaginal septum, creating a bulge into the posterior vaginal wall. The rectovaginal septum is the layer of tissue that separates the rectum from the vagina. When this supportive structure weakens, the rectum can protrude into the vagina, leading to a variety of symptoms and potential complications.

Rectoceles are a common finding in women, with asymptomatic posterior compartment prolapse reported in approximately 40% of parous women. Small rectoceles may be completely asymptomatic and considered a normal finding. However, larger rectoceles can cause discomfort, pelvic pressure, and difficulties with bowel movements.

Causes of rectocele

Several factors can contribute to the development of a rectocele. These include:

Pregnancy and childbirth: Vaginal delivery, especially repeated deliveries, can weaken the muscles and tissues of the pelvic floor, increasing the risk of rectocele formation.
Aging: As women age, the connective tissues in the pelvic area lose elasticity and strength, making them more susceptible to prolapse.
Chronic straining: Long-term constipation, chronic coughing, or heavy lifting can put excessive pressure on the pelvic floor, leading to rectocele development.
Obesity: Carrying extra body weight places additional stress on the pelvic floor tissues, increasing the likelihood of a rectocele.
Surgery: Certain surgical procedures, such as episiotomy or hysterectomy, can weaken the pelvic floor and contribute to rectocele formation.

Symptoms of rectocele

The symptoms associated with a rectocele can vary depending on its size and severity. Some common rectocele symptoms include:

Pelvic pressure or fullness: Women with a rectocele may experience a sensation of pressure or fullness in the vagina or rectum.
Difficulty with bowel movements: A rectocele can cause obstruction during defecation, leading to straining, incomplete evacuation, or the need to manually support the posterior vaginal wall to pass stool (splinting).
Vaginal bulge: In more severe cases, a soft bulge of tissue may be felt in the vagina or even protrude through the vaginal opening.
Sexual dysfunction: A rectocele can cause discomfort during sexual intercourse or lead to feelings of self-consciousness due to the presence of a vaginal bulge.
Rectal pressure: Some women may experience a feeling of fullness or pressure in the rectum, as if something is stuck or not completely emptied after a bowel movement.

It is important to note that many women with a rectocele also have prolapse of other pelvic organs, such as the bladder (cystocele) or uterus. A thorough evaluation by a healthcare provider can help identify the extent of the prolapse and determine the most appropriate course of treatment, which may include both non-surgical and surgical options depending on the severity of symptoms and impact on quality of life.

Diagnosis and Assessment

Physical examination

A thorough physical examination is essential for diagnosing a rectocele and assessing its severity. During the pelvic exam, the healthcare provider will evaluate the vaginal walls and rectum, looking for signs of bulging or herniation. The patient may be asked to bear down as if having a bowel movement, which can cause the rectocele to become more prominent, revealing its size and location. Additionally, the strength of the pelvic floor muscles is assessed by having the patient tighten them as if stopping a stream of urine.

The extent of the prolapse is documented using standardized grading systems, such as the Pelvic Organ Prolapse Quantification (POP-Q) system. This system measures the descent of the vaginal walls with respect to the hymenal ring, providing an objective assessment of the rectocele’s severity. The examiner will also assess the integrity of the rectovaginal fascia and identify any specific defects that may contribute to the development of the rectocele.

A rectovaginal examination is performed to evaluate the integrity of the rectovaginal septum, perineal body, and to identify the presence of an enterocele, which is a herniation of the small intestine into the rectovaginal space. The perineum’s position relative to the ischial tuberosities is also assessed, as perineal descent can be associated with rectoceles and other pelvic floor disorders.

Imaging tests

Imaging studies, such as fluoroscopic defecography and dynamic magnetic resonance imaging (MRI), can provide valuable information about the presence and severity of a rectocele, as well as any coexisting pelvic organ prolapse. These tests allow for the visualization of the pelvic floor anatomy and function during simulated defecation, helping to identify any abnormalities in the rectal wall and its relationship to the vagina.

Fluoroscopic defecography involves the injection of a contrast material into the rectum, followed by X-ray imaging during defecation. This test can demonstrate the size and location of the rectocele, as well as any associated functional disorders, such as incomplete evacuation or paradoxical puborectalis contraction.

Dynamic MRI offers a radiation-free alternative to fluoroscopic defecography and provides high-resolution images of the pelvic floor. This modality can accurately assess the size of the rectocele and identify any coexisting pelvic organ prolapse, such as cystocele or uterine prolapse. MRI can also help evaluate the integrity of the pelvic floor muscles and fascia, which is essential for planning surgical interventions.

Grading systems

Grading systems are used to classify the severity of a rectocele based on its size and the degree of protrusion into the vagina. The most commonly used grading system is the POP-Q system, which measures the descent of the vaginal walls relative to the hymenal ring. This system assigns stages to the prolapse, ranging from Stage 0 (no prolapse) to Stage IV (complete eversion of the vagina).

Another grading system specifically for rectoceles is based on the size of the herniation as measured on imaging studies. Small rectoceles are those that measure less than 2 cm in depth, medium rectoceles are 2-4 cm, and large rectoceles are greater than 4 cm.

Accurately grading the severity of a rectocele is crucial for determining the most appropriate treatment approach. Non-surgical management, such as pelvic floor muscle training and pessary use, may be sufficient for small to medium rectoceles, while large or symptomatic rectoceles may require surgical intervention.

In summary, a comprehensive evaluation of rectocele involves a thorough physical examination, imaging studies, and the use of standardized grading systems. This multifaceted approach allows for an accurate diagnosis, assessment of severity, and identification of any coexisting pelvic floor disorders, enabling the development of an individualized treatment plan tailored to the patient’s specific needs and goals.

Non-Surgical Treatment Options

Lifestyle modifications

Lifestyle modifications can play a significant role in managing rectocele symptoms and preventing the condition from worsening. One of the most important changes is to avoid constipation by eating a high-fiber diet, drinking plenty of fluids, and, if needed, taking a fiber supplement. Straining during bowel movements can exacerbate rectocele, so it is crucial to maintain regular, soft stools. Achieving and maintaining a healthy weight is also beneficial, as excess body weight places additional stress on the pelvic floor tissues. Other lifestyle changes that can help alleviate rectocele symptoms include avoiding heavy lifting and controlling chronic cough, which can put excessive pressure on the pelvic floor.

Pelvic floor exercises

Pelvic floor exercises, also known as Kegel exercises, are an effective way to strengthen the muscles that support the pelvic organs. A strong pelvic floor provides better support for the rectum and vagina, potentially relieving rectocele symptoms. To perform Kegel exercises, one must identify the correct muscles by imagining they are trying to stop the flow of urine. Once the muscles are located, the individual should contract them for a few seconds, then relax. This process should be repeated several times a day, gradually increasing the duration of the contractions and the number of repetitions as the muscles become stronger. Pelvic floor exercises may be most successful when taught by a physical therapist or nurse practitioner and reinforced with biofeedback, which uses monitoring devices to ensure the correct muscles are being tightened effectively.

Pessaries

Pessaries are removable devices that can be inserted into the vagina to support the pelvic organs, including the rectum. They come in various shapes and sizes, and a healthcare provider can help determine the most appropriate type for an individual’s specific needs. The ring pessary is the most commonly recommended device for treating mild to moderate rectocele. It is easy to care for, as it can be removed and cleaned regularly by the patient. For more severe cases, a Gellhorn pessary may be recommended, as it provides stronger support. However, this type of pessary can be more difficult to insert and remove, often requiring assistance from a healthcare provider. Pessaries can cause vaginal irritation and ulceration, so it is essential to maintain proper vaginal hygiene and attend regular follow-up appointments to monitor the device’s fit and the health of the vaginal tissues. While pessaries can effectively manage rectocele symptoms, they are not a permanent solution and may not be suitable for all women, particularly those who are sexually active or have recurrent vaginal ulcerations due to pessary use.

In summary, non-surgical treatment options for rectocele include lifestyle modifications, pelvic floor exercises, and the use of pessaries. These conservative approaches can help alleviate symptoms and improve quality of life for many women with mild to moderate rectocele. However, in cases where non-surgical methods do not provide adequate relief or the rectocele is severe, surgical intervention may be necessary to correct the condition and restore normal function.

Surgical Interventions

When non-surgical treatment options fail to provide adequate relief from rectocele symptoms, surgical intervention may be necessary. The goal of rectocele repair surgery is to reinforce the weakened rectovaginal septum and restore normal anatomy. Several surgical approaches can be used, depending on the severity of the rectocele, the patient’s symptoms, and the surgeon’s preference.

Transvaginal approach

The transvaginal approach, also known as posterior colporrhaphy, is the most common surgical technique for rectocele repair. In this procedure, an incision is made in the posterior vaginal wall, and the rectovaginal septum is identified. The weakened or torn fascia is then plicated or sutured together to strengthen the septum and reduce the bulging of the rectum into the vagina. Excess vaginal mucosa may be removed before closing the incision. Advantages of the transvaginal approach include minimal scarring, faster recovery time, and the ability to address other vaginal prolapse issues simultaneously. However, this approach may not be suitable for women with severe rectoceles or those with significant rectal symptoms.

Transanal approach

The transanal approach involves accessing the rectocele through the anus and rectum. One such technique is the stapled transanal rectal resection (STARR) procedure, which uses a circular stapler to remove excess rectal tissue and reinforce the rectovaginal septum. This approach is particularly useful for patients with obstructed defecation syndrome (ODS) and internal rectal intussusception. The STARR procedure has been shown to be effective in improving rectal sensation and reducing symptoms of ODS. However, it carries a higher risk of complications, such as rectal bleeding, pain, and fecal urgency, compared to the transvaginal approach.

Abdominal approach

In some cases, an abdominal approach may be necessary to repair a rectocele, particularly when it is associated with other pelvic floor disorders or when previous surgical attempts have failed. Abdominal procedures, such as sacrocolpopexy or rectopexy, involve using mesh to suspend and support the vaginal vault or rectum to the sacrum. These procedures can be performed through an open incision or laparoscopically, depending on the surgeon’s expertise and the patient’s specific needs. While abdominal approaches provide excellent anatomical outcomes, they are more invasive and have a longer recovery time compared to transvaginal or transanal techniques.

The choice of surgical approach for rectocele repair depends on various factors, including the size and location of the rectocele, the presence of associated pelvic floor disorders, and the patient’s overall health and preferences. A thorough evaluation by a multidisciplinary team, consisting of a urogynecologist, colorectal surgeon, and pelvic floor physical therapist, can help determine the most appropriate surgical intervention for each individual patient. Postoperative care and rehabilitation, including pelvic floor muscle training and lifestyle modifications, are crucial for optimizing surgical outcomes and preventing recurrence.

Conclusion

The management of rectocele involves a range of approaches, from lifestyle changes to surgical interventions. Understanding the condition and its symptoms has a significant impact on choosing the right treatment path. Non-surgical options like pelvic floor exercises and pessaries offer relief for many women, while surgical procedures provide a solution for more severe cases. The choice of treatment depends on the individual’s symptoms, the severity of the rectocele, and overall health considerations.

To wrap up, rectocele treatment is a journey that requires patience and often a combination of methods to achieve the best results. Whether through conservative management or surgical repair, the goal is to improve quality of life and alleviate discomfort. With ongoing advancements in medical techniques and a better understanding of pelvic floor disorders, women with rectocele have more options than ever to address their condition effectively.
