Rectovaginal Fistula: Causes, Symptoms, And Treatment

Rectovaginal Fistula: Causes, Symptoms, And Treatment

A rectovaginal fistula (RVF) is a distressing medical condition characterized by an abnormal connection between the rectum and the vagina. This connection leads to the passage of stool or gas from the rectum into the vagina, causing significant discomfort, embarrassment, and potential health issues. Lets explore the causes, symptoms, diagnosis, and treatment options for rectovaginal fistulas. 

What Is Rectovaginal Fistula?

A rectovaginal fistula is an abnormal passage or tunnel that develops between the rectum (the last part of the large intestine) and the vagina. This connection allows stool, gas, or sometimes even pus to pass between the two organs. RVFs can vary in size and severity, and their causes may also differ.

Types of Rectovaginal Fistulas

There are several types of RVFs, including congenital (present from birth) and acquired (developed due to an injury or medical condition). The most common acquired RVFs result from obstetric complications during childbirth, surgical complications, inflammatory bowel diseases like Crohn’s disease, or radiation therapy for pelvic cancers.

Causes of Rectovaginal Fistulas

Understanding the underlying causes of RVFs is essential for proper management. Common causes include:

  1. Obstetric injuries during childbirth.
  2. Surgical complications (e.g. after colorectal surgery).
  3. Inflammatory bowel diseases (e.g. Crohn’s disease).
  4. Radiation therapy for pelvic cancers.
  5. Trauma or injury to the pelvic area.

How To Identify A Rectovaginal Fistula?

Recognizing the signs and symptoms of an RVF is crucial for early diagnosis. Common indicators include:

  1. Passage of stool or gas through the vagina.
  2. Foul-smelling vaginal discharge.
  3. Recurrent urinary tract infections (UTIs).
  4. Pain or discomfort in the pelvic region.
  5. Vaginal irritation or itching.

Impact On Quality of Life Due To Rectovaginal Fistula

RVFs can significantly affect a person’s quality of life. The constant leakage of stool or gas can lead to social isolation, emotional distress, and a decreased ability to perform daily activities comfortably.

Diagnosing Rectovaginal Fistula

  1. Physical Examination – A physical examination, including a pelvic exam, is often the first step in diagnosing an RVF. During the exam, a healthcare provider may detect the abnormal passage between the rectum and vagina.
  2. Imaging And Diagnostic Tests – Additional tests may be required to confirm the diagnosis and assess the extent and location of the RVF. These tests can include:
  • Endoscopy: A flexible tube with a camera (endoscope) is inserted into the rectum to visualize the fistula.
  • Barium enema: A contrast material (barium) is used during X-rays to highlight the RVF.
  • Magnetic Resonance Imaging (MRI): This imaging technique can provide detailed images of the pelvic area.

Treatment Options For Rectovaginal Fistula

Treating an RVF depends on its size, location, and underlying causes. Treatment options include:

Conservative Management

Small, uncomplicated RVFs may heal on their own with conservative measures such as dietary changes, antibiotics to prevent infection, and stool softeners to reduce bowel movements’ irritation.

Surgical Intervention

Most RVFs require surgical repair. Surgical options include:

  1. Primary Repair: The fistula is closed with sutures.
  2. Advancement Flap Repair: A nearby tissue flap is used to cover the fistula.
  3. Colostomy: In severe cases, a temporary colostomy may be necessary to divert stool away from the repaired area while it heals.

Emerging Therapies

Researchers are exploring newer therapies, including tissue grafts and biologic agents, to improve RVF treatment outcomes.

Post-Surgery Care

After surgical repair, patients need to follow their healthcare provider’s instructions carefully. This may include dietary restrictions, hygiene measures, and follow-up appointments to monitor healing. There are always chances of the repair not being successful.

Lifestyle Changes

Living with an RVF may require certain lifestyle adjustments, including dietary modifications and strategies for managing symptoms. Support from healthcare providers and support clinical networks is invaluable during this time.

Living With A Rectovaginal Fistula

  1. Coping Strategies – Coping with an RVF can be emotionally challenging. Seeking support from mental health professionals and connecting with support groups can help individuals navigate the emotional aspects of living with this condition.
  2. Support Networks – Support groups and online communities provide a platform for individuals to share experiences, tips, and emotional support with others facing similar challenges.

The rectovaginal fistula can significantly impact a person’s physical and emotional well-being. Early diagnosis and appropriate treatment, which may include surgery, are essential for managing this condition effectively. With proper care and support, individuals with RVFs can improve their quality of life and regain control over their health.
