WHAT CAUSES RECTOVAGINAL FISTULA?
THE COMPLETE EVIDENCE-BASED GUIDE TO RECTOVAGINAL FISTULA: CAUSES, RISK FACTORS, SYMPTOMS, DIAGNOSIS, TREATMENT, PREVENTION, SURGICAL REPAIR, RECOVERY, AND LONG-TERM OUTCOMES
INTRODUCTION: WHAT CAUSES A RECTOVAGINAL FISTULA?
A rectovaginal fistula is a distressing condition in which an abnormal opening develops between the rectum and the vagina, allowing stool, gas, mucus, or intestinal contents to pass through the vagina instead of the anus. This condition can be physically uncomfortable, emotionally devastating, and socially isolating, often affecting a woman's confidence, relationships, reproductive health, and quality of life.
Many women first notice the problem after a difficult childbirth, while others develop it following pelvic surgery, inflammatory bowel disease, cancer treatment, severe infections, or trauma. Regardless of the cause, a rectovaginal fistula is not a normal condition and requires prompt medical evaluation.
Although some small fistulas may occasionally heal with conservative treatment, most established rectovaginal fistulas require specialized surgical repair. Fortunately, advances in colorectal and reconstructive pelvic surgery have greatly improved treatment outcomes, allowing many women to regain normal bowel control and return to healthy, productive lives.
Understanding what causes a rectovaginal fistula is the first step toward prevention, early diagnosis, effective treatment, and long-term recovery.
WHAT IS A RECTOVAGINAL FISTULA?
A rectovaginal fistula is an abnormal passage that forms between:
- The rectum.
- The vagina.
Because of this abnormal connection:
- Stool may pass through the vagina.
- Intestinal gas may escape through the vagina.
- Mucus may leak continuously.
- Vaginal infections may occur repeatedly.
The size of the fistula may range from a tiny opening to a large defect.
HOW DOES A RECTOVAGINAL FISTULA DEVELOP?
A fistula develops when tissues separating the rectum from the vagina become injured or destroyed.
The damaged tissues may result from:
- Loss of blood supply.
- Infection.
- Surgical injury.
- Inflammation.
- Trauma.
- Radiation damage.
As healing occurs, an abnormal tunnel forms between the two organs.
PROLONGED OBSTRUCTED LABOUR
Worldwide, prolonged obstructed labour remains one of the leading causes of rectovaginal fistula.
When labour continues for many hours without successful delivery:
- The baby's head compresses pelvic tissues.
- Blood supply is interrupted.
- Tissue dies.
- Several days later the damaged tissue separates.
- A fistula develops between the rectum and vagina.
This type of fistula is classified as an obstetric rectovaginal fistula.
SEVERE PERINEAL TEARS DURING CHILDBIRTH
Some women develop rectovaginal fistulas following severe childbirth tears involving the anal sphincter and rectum.
These injuries are known as:
- Third-degree perineal tears.
- Fourth-degree perineal tears.
Although many heal well after immediate repair, some women later develop a fistula because healing is incomplete or infection occurs.
SURGICAL COMPLICATIONS
Pelvic surgery may occasionally injure the rectum or vaginal wall.
Examples include:
- Hysterectomy.
- Pelvic reconstructive surgery.
- Rectal surgery.
- Cancer surgery.
- Complex gynaecological procedures.
Although uncommon, accidental injury may later result in fistula formation.
CROHN'S DISEASE
Crohn's disease is a chronic inflammatory bowel disease that may cause deep ulcers within the intestine.
These ulcers may gradually extend into nearby organs, creating fistulas.
Women with Crohn's disease may develop:
- Rectovaginal fistulas.
- Perianal fistulas.
- Enterovaginal fistulas.
Treatment often requires both medical therapy and surgery.
RADIATION THERAPY
Radiotherapy used to treat pelvic cancers may damage healthy tissues.
Months or years after treatment, poor blood supply and tissue breakdown may result in:
- Rectovaginal fistulas.
- Bladder fistulas.
- Complex pelvic fistulas.
Radiation-induced fistulas are often more difficult to repair because healing capacity is reduced.
PELVIC INFECTIONS AND ABSCESSES
Severe infections within the pelvis may destroy surrounding tissues.
Examples include:
- Pelvic abscesses.
- Deep anorectal infections.
- Severe postpartum infections.
If untreated, these infections may eventually form a fistula.
TRAUMA
Traumatic injuries may damage both the rectum and vagina.
Possible causes include:
- Road traffic accidents.
- Penetrating injuries.
- Sexual assault.
- Pelvic fractures.
- Obstetric trauma.
Prompt treatment reduces the risk of fistula formation.
CAN CANCER CAUSE A RECTOVAGINAL FISTULA?
Yes.
Advanced cancers involving the:
- Rectum.
- Cervix.
- Vagina.
- Uterus.
- Pelvis.
may invade surrounding tissues and create abnormal connections between organs.
Cancer-related fistulas require treatment of both the fistula and the underlying cancer.
CLINICAL SIGNIFICANCE
Rectovaginal fistulas arise from a wide variety of conditions, but prolonged obstructed labour remains one of the leading causes worldwide. Early recognition of obstetric emergencies, prompt treatment of pelvic infections, careful surgical technique, and effective management of inflammatory bowel disease play vital roles in preventing this life-changing condition.
CONCLUSION
A rectovaginal fistula develops when the normal tissues separating the rectum and vagina are destroyed by childbirth injury, inflammation, infection, surgery, radiation, trauma, or cancer. Although the condition causes significant physical and emotional distress, early diagnosis and modern reconstructive surgery provide excellent opportunities for recovery and restoration of quality of life.

CONCLUSION
Rectovaginal fistula can usually be diagnosed through a careful medical history, thorough physical examination, and appropriate investigations. Early recognition prevents prolonged suffering, reduces complications, and significantly improves the likelihood of successful treatment and restoration of normal bowel and vaginal function.
HOW IS A RECTOVAGINAL FISTULA TREATED?
Treatment depends on several important factors, including:
- The size of the fistula.
- Its location.
- The underlying cause.
- The amount of tissue damage.
- Whether infection is present.
- Whether Crohn's disease or cancer is involved.
- Previous repair attempts.
- The woman's overall health.
The primary goals of treatment are to:
- Close the abnormal opening.
- Eliminate stool leakage through the vagina.
- Restore normal bowel function.
- Prevent infection.
- Preserve sexual and reproductive health where possible.
- Restore dignity and quality of life.
Modern treatment usually combines medical care, nutritional support, and reconstructive surgery.
INITIAL MEDICAL STABILIZATION
Before definitive treatment, healthcare professionals carefully assess the patient's condition.
Initial management may include:
- Physical examination.
- Blood investigations.
- Nutritional assessment.
- Treatment of dehydration.
- Correction of anaemia.
- Assessment for infection.
- Evaluation of bowel function.
Women who are seriously ill are stabilized before surgery is considered.
CONTROL OF INFECTION
Active infection significantly reduces the success of fistula repair.
Treatment may include:
- Appropriate antibiotics.
- Drainage of abscesses.
- Wound care.
- Treatment of surrounding skin infections.
Whenever possible, infection should be completely controlled before surgery.
NUTRITIONAL REHABILITATION
Good nutrition is essential for tissue healing.
Patients are encouraged to consume:
- High-quality protein.
- Iron-rich foods.
- Fresh fruits.
- Vegetables.
- Whole grains.
- Adequate fluids.
Some women with severe bowel disease or malnutrition may require specialized nutritional support before surgery.
Healthy nutrition improves wound healing and reduces postoperative complications.
CAN A RECTOVAGINAL FISTULA HEAL WITHOUT SURGERY?
A very small number of tiny, recently formed fistulas may occasionally close with conservative treatment if:
- Tissue damage is minimal.
- Infection is absent.
- The underlying cause has been corrected.
However, most established rectovaginal fistulas require surgical repair because the abnormal tract rarely closes spontaneously.
WHEN IS SURGERY NECESSARY?
Surgery is usually recommended when:
- Stool continues to pass through the vagina.
- Conservative treatment fails.
- The fistula is large.
- Infection has been controlled.
- The fistula significantly affects quality of life.
- Crohn's disease is medically controlled but the fistula persists.
Early referral to an experienced colorectal or pelvic reconstructive surgeon improves outcomes.
TYPES OF SURGICAL REPAIR
The surgical technique depends on:
- The size of the fistula.
- Its location.
- The condition of surrounding tissues.
- Previous repair attempts.
Common approaches include:
- Vaginal repair.
- Perineal repair.
- Transanal repair.
- Abdominal repair.
- Combined abdominal and vaginal procedures for complex fistulas.
The surgeon selects the most appropriate approach for each patient.
WHAT IS A TEMPORARY COLOSTOMY?
In some complex cases, a temporary colostomy may be recommended.
A colostomy diverts stool away from the healing fistula by bringing part of the large intestine to an opening in the abdominal wall.
This allows:
- The repaired tissues to heal.
- Infection to resolve.
- Inflammation to decrease.
- The risk of repair failure to be reduced.
Once healing is complete, the colostomy can often be reversed.
Not every patient requires a colostomy.
FACTORS THAT IMPROVE SURGICAL SUCCESS
Successful healing is more likely when:
- Infection has been treated.
- Nutrition is adequate.
- Crohn's disease is well controlled.
- Smoking has been stopped.
- Diabetes is well controlled.
- Surgery is performed by experienced specialists.
Proper preparation before surgery greatly improves long-term results.
WHEN SHOULD SURGERY BE DELAYED?
Surgery may be postponed when:
- Severe infection is present.
- Extensive inflammation persists.
- Tissues are badly damaged immediately after childbirth.
- Nutritional status is poor.
- Active Crohn's disease is uncontrolled.
Treating these problems first creates better conditions for successful repair.
CLINICAL SIGNIFICANCE
Successful treatment of a rectovaginal fistula requires more than simply closing the opening. Infection control, nutritional rehabilitation, careful timing of surgery, management of underlying diseases, and expert reconstructive techniques all contribute to long-term healing and restoration of bowel function.
CONCLUSION
Although conservative treatment has an important role in selected patients, most rectovaginal fistulas require specialized surgical repair. Early diagnosis, treatment of infection, optimization of nutrition, and referral to experienced surgeons significantly improve healing rates and reduce the risk of recurrence.
RECOVERY AFTER RECTOVAGINAL FISTULA SURGERY
Recovery following rectovaginal fistula repair requires patience, careful medical supervision, and strict adherence to postoperative instructions. Although surgical techniques have advanced considerably, the success of the operation depends not only on the surgeon's skill but also on proper healing, infection prevention, nutritional support, and regular follow-up.
Recovery varies according to:
- The size of the fistula.
- Its location.
- The underlying cause.
- The type of surgery performed.
- The woman's nutritional status.
- Whether previous repairs have been attempted.
- The presence of Crohn's disease or other chronic illnesses.
Most women experience progressive improvement over several weeks to months.
IMMEDIATE POSTOPERATIVE CARE
After surgery, healthcare professionals closely monitor:
- Blood pressure.
- Heart rate.
- Temperature.
- Pain level.
- Wound healing.
- Bowel function.
- Fluid balance.
- Signs of infection.
Careful observation allows early detection and treatment of complications.
WOUND CARE
Keeping the surgical wound clean is essential for successful healing.
Patients are advised to:
- Follow wound care instructions carefully.
- Maintain good personal hygiene.
- Keep the perineal area clean and dry.
- Wash gently after bowel movements.
- Change dressings when instructed.
Healthcare professionals monitor the wound for:
- Redness.
- Swelling.
- Persistent drainage.
- Separation of stitches.
- Signs of infection.
BOWEL MANAGEMENT AFTER SURGERY
Protecting the surgical repair requires careful bowel management.
Healthcare professionals often recommend:
- Soft stools.
- Adequate hydration.
- High-fibre foods when appropriate.
- Stool softeners if prescribed.
- Avoiding excessive straining during bowel movements.
Preventing constipation is one of the most important aspects of recovery.
DIET DURING RECOVERY
Good nutrition supports tissue repair and reduces complications.
A healthy recovery diet should include:
- Lean meats.
- Fish.
- Eggs.
- Beans.
- Fresh fruits.
- Vegetables.
- Whole grains.
- Foods rich in vitamin C.
- Iron-rich foods.
- Adequate fluids.
Patients with Crohn's disease or intestinal surgery may require individualized dietary advice.
PAIN MANAGEMENT
Mild postoperative discomfort is expected.
Pain is controlled using appropriate medications prescribed by the treating healthcare professional.
Patients should immediately report:
- Severe worsening pain.
- Fever.

- Increasing wound discharge.
These symptoms require prompt reassessment.
WHEN CAN NORMAL ACTIVITIES BE RESUMED?
Recovery should be gradual.
Women are usually encouraged to:
- Walk regularly.
- Avoid prolonged bed rest.
- Resume light household activities gradually.
However, they should avoid:
- Heavy lifting.
- Strenuous exercise.
- Activities that increase pelvic pressure.
The timing varies according to the extent of surgery.
SEXUAL ACTIVITY AFTER SURGERY
Sexual intercourse should be postponed until complete healing has occurred.
Resuming intercourse too early may:
- Damage the repair.
- Cause pain.
- Increase the risk of recurrence.
The surgeon will advise when it is safe to resume sexual activity, which is often after several weeks or months depending on healing.
FUTURE PREGNANCY AFTER RECTOVAGINAL FISTULA REPAIR
Many women can become pregnant after successful repair.
Future pregnancies require:
- Early antenatal care.
- Regular obstetric follow-up.
- Delivery in a well-equipped hospital.
For women whose fistula resulted from childbirth, a planned Caesarean section is often recommended to reduce the risk of recurrent injury to the repaired tissues.
PREVENTING RECURRENCE
The risk of recurrence can be reduced by:
- Treating constipation promptly.
- Avoiding prolonged straining.
- Managing Crohn's disease effectively.
- Maintaining good nutrition.
- Treating pelvic infections early.
- Receiving skilled obstetric care during future pregnancies.
- Following all postoperative instructions.
These measures promote long-term healing.
LONG-TERM FOLLOW-UP
Regular follow-up allows healthcare professionals to:
- Confirm complete healing.
- Detect recurrence early.
- Assess bowel function.
- Evaluate continence.
- Manage persistent symptoms.
- Provide emotional support and counselling.
Long-term follow-up is especially important for women with Crohn's disease or complex fistulas.
QUALITY OF LIFE AFTER SUCCESSFUL REPAIR
Successful treatment often restores:
- Normal bowel control.
- Vaginal health.
- Personal confidence.
- Sexual wellbeing.
- Family relationships.
- Social participation.
- Ability to work.
- Emotional wellbeing.
For many women, successful repair represents a return to normal life after months or years of physical and emotional suffering.
CLINICAL SIGNIFICANCE
Recovery from rectovaginal fistula repair requires a multidisciplinary approach involving surgeons, nurses, nutritionists, physiotherapists when appropriate, and mental health professionals. Careful postoperative management, bowel protection, infection prevention, and long-term follow-up are essential for maintaining successful surgical outcomes.
CONCLUSION
Most women who undergo successful rectovaginal fistula repair can achieve excellent long-term outcomes. Careful postoperative care, healthy nutrition, proper bowel management, gradual return to daily activities, and regular follow-up greatly reduce complications and recurrence while restoring dignity, health, and quality of life.
RECTOVAGINAL FISTULA IN SPECIAL POPULATIONS
Although rectovaginal fistulas can affect women of any age, the causes, treatment, and long-term outcomes differ depending on the underlying condition. Factors such as childbirth, inflammatory bowel disease, cancer, previous surgery, radiation therapy, age, nutritional status, and access to specialist healthcare all influence the likelihood of developing a fistula and the success of treatment.
Understanding these differences helps healthcare professionals provide individualized care while improving recovery and reducing the risk of recurrence.
RECTOVAGINAL FISTULA IN ADOLESCENT MOTHERS
Adolescent girls are among the most vulnerable to obstetric rectovaginal fistulas.
Contributing factors include:
- An underdeveloped pelvis.
- Early marriage.
- Teenage pregnancy.
- Malnutrition.
- Limited antenatal care.
- Delayed access to emergency obstetric services.
Because labour is more likely to become obstructed, prolonged pressure from the baby's head may damage the tissues separating the rectum and vagina.
Preventing adolescent pregnancy and improving access to skilled maternity care are among the most effective preventive strategies.
RECTOVAGINAL FISTULA IN WOMEN WITH CROHN'S DISEASE
Crohn's disease is a chronic inflammatory bowel disorder that may cause deep ulcers and fistula formation.
Women with Crohn's disease often require:
- Long-term medical therapy.
- Nutritional support.
- Regular monitoring.
- Biological medications.
- Surgery for persistent or complex fistulas.
Successful treatment requires close collaboration between gastroenterologists and colorectal surgeons.
RADIATION-INDUCED RECTOVAGINAL FISTULAS
Radiotherapy used to treat cancers of the cervix, uterus, rectum, or pelvis may damage healthy tissues.
Months or even years after treatment, reduced blood supply and progressive tissue breakdown may result in a rectovaginal fistula.
These fistulas are often:
- More complex.
- Slower to heal.
- More difficult to repair surgically.
Treatment requires highly experienced reconstructive surgeons.
CANCER-RELATED RECTOVAGINAL FISTULAS
Advanced pelvic cancers may directly invade nearby organs, creating abnormal communications between the rectum and vagina.
Examples include:
- Cervical cancer.
- Rectal cancer.
- Vaginal cancer.
- Endometrial cancer.
Treatment focuses on:
- Managing the underlying cancer.
- Controlling symptoms.
- Repairing the fistula when appropriate.
- Improving quality of life.
POST-SURGICAL RECTOVAGINAL FISTULAS
Although uncommon, fistulas may develop after pelvic operations such as:
- Hysterectomy.
- Colorectal surgery.
- Pelvic floor reconstruction.
- Cancer surgery.
Early recognition of surgical injury greatly improves the chances of successful repair.
THE PSYCHOLOGICAL IMPACT
The emotional consequences of rectovaginal fistula are often profound.
Many women experience:
- Shame.
- Anxiety.
- Depression.
- Loss of self-esteem.
- Fear of social interaction.
- Emotional exhaustion.
- Grief.
Professional psychological support should be considered an essential part of comprehensive treatment.
SOCIAL STIGMA
Because stool or gas may pass through the vagina unexpectedly, many women experience:
- Social embarrassment.
- Isolation.
- Difficulty attending work.
- Avoidance of religious gatherings.
- Withdrawal from community activities.
Some women become isolated simply because they fear unpleasant odour or accidental leakage.
Successful treatment often restores confidence and social participation.
MARITAL AND SEXUAL RELATIONSHIPS
Rectovaginal fistula may significantly affect intimate relationships.
Women may experience:
- Pain during intercourse.
- Fear of intimacy.
- Reduced sexual confidence.
- Relationship difficulties.
- Separation or divorce in severe cases.
Open communication, counselling, and successful surgical treatment frequently improve these problems.

- Emotional wellbeing.
- Healthy intimate relationships.
- Ability to work.
- Social participation.
- Family life.
Comprehensive rehabilitation allows many women to return to normal daily activities.
CLINICAL SIGNIFICANCE
Rectovaginal fistulas affect much more than bowel function. They have profound physical, psychological, reproductive, and social consequences. Comprehensive management therefore requires a multidisciplinary approach involving surgeons, gastroenterologists, obstetricians, specialist nurses, nutritionists, physiotherapists where appropriate, and mental health professionals.
CONCLUSION
Rectovaginal fistulas affect women differently depending on the underlying cause, age, associated medical conditions, and access to specialist care. Despite the significant challenges they present, modern multidisciplinary management has made successful treatment possible for many women. Early diagnosis, individualized care, emotional support, and long-term follow-up remain the cornerstones of successful recovery.
FREQUENTLY ASKED QUESTIONS (FAQs)
Can a rectovaginal fistula heal without surgery?
In rare cases, a very small, recently formed rectovaginal fistula may heal with conservative treatment if:
- The fistula is very small.
- Infection is absent.
- The surrounding tissues are healthy.
- The underlying cause has been corrected.
However, most established rectovaginal fistulas require surgical repair because they rarely close on their own.
Can antibiotics cure a rectovaginal fistula?
No.
Antibiotics help treat infections associated with a fistula but cannot close the abnormal opening.
They are often used before surgery to control infection and reduce inflammation.
Can Crohn's disease medications close a fistula?
Sometimes.
Modern biologic medications and other treatments for Crohn's disease may reduce inflammation and allow some fistulas to heal.
However, many women with Crohn's-related rectovaginal fistulas eventually require surgery.
Will I be able to have children after rectovaginal fistula repair?
Many women can become pregnant after successful treatment.
If the fistula resulted from childbirth, future pregnancies should be managed by experienced obstetricians.
A planned Caesarean section is often recommended to reduce the risk of another childbirth injury.

COMMON MYTHS AND SCIENTIFIC FACTS
Myth: Rectovaginal fistulas are caused by witchcraft or curses.
Fact
Rectovaginal fistulas are medical conditions caused by childbirth injuries, surgery, Crohn's disease, infections, radiation therapy, trauma, or cancer. They are not caused by spiritual forces.
Myth: Every rectovaginal fistula requires emergency surgery.
Fact
Not every fistula requires immediate emergency surgery. Some women need treatment for infection, nutritional rehabilitation, or medical stabilization before definitive repair.
Myth: Herbal remedies can permanently cure a rectovaginal fistula.
Fact
There is no reliable scientific evidence that herbal remedies can permanently close an established rectovaginal fistula.
Delaying specialist treatment may increase the risk of complications.
Myth: A successful operation guarantees the fistula will never return.
Fact
Most women recover well after surgery, but recurrence is possible, especially if the underlying disease remains active or another childbirth injury occurs.
Myth: Women with rectovaginal fistulas cannot live normal lives again.
Fact
With appropriate medical care, reconstructive surgery, rehabilitation, and emotional support, many women regain normal bowel control, healthy relationships, and an excellent quality of life.
Myth: Rectovaginal fistulas are contagious.
Fact
Rectovaginal fistulas cannot be transmitted from one person to another through physical contact or sexual intercourse.
WARNING SIGNS THAT REQUIRE IMMEDIATE MEDICAL ATTENTION
Seek urgent medical care if you develop:
- Stool passing through the vagina.
- Persistent passage of gas through the vagina.
- High fever.
- Severe pelvic or abdominal pain.
- Heavy rectal or vaginal bleeding.
- Persistent foul-smelling vaginal discharge.
- Rapidly worsening symptoms.
- Confusion or fainting.
These symptoms may indicate serious infection or other life-threatening complications requiring immediate treatment.
KEY TAKE-HOME MESSAGES
- Rectovaginal fistula is an abnormal connection between the rectum and the vagina.
- Prolonged obstructed labour remains one of the leading causes worldwide.
- Crohn's disease, pelvic surgery, cancer, radiation therapy, and severe infections are other important causes.
- Stool or gas passing through the vagina is never normal.
- Most established rectovaginal fistulas require surgical repair.
- Early diagnosis greatly improves treatment success.
- Comprehensive rehabilitation restores health, dignity, and quality of life for many women.
FINAL CONCLUSION
Rectovaginal fistula is one of the most distressing disorders affecting women's pelvic health because it disrupts bowel control, causes persistent leakage of stool or gas through the vagina, and often leads to profound emotional, social, and marital difficulties. Fortunately, modern medicine has transformed the outlook for affected women. Early diagnosis, careful evaluation, treatment of infection, nutritional optimization, and specialized reconstructive surgery now provide excellent outcomes for many patients.
Preventing rectovaginal fistulas remains equally important. Improving access to skilled obstetric care, preventing prolonged obstructed labour, treating Crohn's disease appropriately, performing safe pelvic surgery, and managing pelvic infections promptly can dramatically reduce the number of women affected by this preventable condition.
The most important message is this: stool or gas passing through the vagina is never normal. Women experiencing these symptoms should seek immediate medical evaluation because early treatment offers the greatest opportunity for complete healing, restored dignity, and an excellent long-term quality of life.
