Colovaginal fistula

Dear Dr.
Hou Yong-ji,
My mother-in-law is in her sixties and underwent surgery last year for stage III rectal cancer, which involved resection and the creation of a temporary colostomy, followed by six months of chemotherapy.
During the process of reversing the colostomy, a fistula was discovered in her vagina, which had to be sutured.
After persistent requests from my mother-in-law, the doctor finally reversed the colostomy in May of this year.
However, it was discovered afterward that the colovaginal fistula had not healed, resulting in fecal leakage from the vagina, causing her significant distress.
Should we consult a urologist or a gynecologist for this condition? Is it possible to perform another surgical repair, or should we see a colorectal specialist again? Thank you.

Hello: A rectovaginal fistula is a very troublesome issue.
First, it should be differentiated: (1) Is it caused by cancer recurrence? (2) Has there been any radiation therapy? (3) Or is it a complication from surgery? Depending on the different conditions, different treatments are required.
Therefore, please first consult the original surgeon.
If the surgeon is unable to manage the situation, please prepare the previous surgical and medical records and seek proper management from a colorectal surgeon.
Thank you.

More Info

Colovaginal fistula is a challenging condition that can arise after surgical procedures, particularly those involving the rectum or colon, such as the resection of rectal cancer. This type of fistula is an abnormal connection between the colon and the vagina, leading to the passage of fecal matter into the vaginal canal, which can cause significant discomfort, hygiene issues, and emotional distress for the patient.

In your case, your mother-in-law has experienced this complication following her surgery for rectal cancer. The presence of a colovaginal fistula can be particularly distressing, and it is essential to approach the treatment options with a multidisciplinary perspective.

Treatment Options
1. Conservative Management: In some cases, small fistulas may close spontaneously over time, especially if the patient is not experiencing significant symptoms. However, this is less likely with larger or more complex fistulas.

2. Surgical Repair: Surgical intervention is often necessary for colovaginal fistulas. The goal of surgery is to close the fistula and restore normal anatomy. This may involve:
- Fistula Excision: The surgeon may excise the fistula tract and surrounding tissue to promote healing.

- Tissue Flaps: In some cases, tissue from nearby areas may be used to cover the defect and enhance healing.

- Colostomy: In certain situations, a temporary colostomy may be necessary to divert fecal matter away from the surgical site, allowing the fistula to heal.

3. Multidisciplinary Approach: Given the complexity of colovaginal fistulas, it is often beneficial to involve multiple specialists in the treatment plan. This may include:
- Colorectal Surgeons: They specialize in diseases of the colon, rectum, and anus and are typically the primary surgeons for fistula repairs.

- Gynecologists: They can provide insight into the vaginal aspect of the fistula and assist in surgical repair.

- Urologists: If there are associated urinary issues, a urologist may also be involved.

Specialist Guidance
In your mother-in-law's case, it would be advisable to consult with a colorectal surgeon who has experience in managing colovaginal fistulas. They can assess the current state of the fistula and recommend the most appropriate surgical approach. If the fistula is not healing or if there are complications, a second surgical intervention may be necessary.

Additionally, if there are concerns about the vaginal aspect of the fistula, a gynecologist should be consulted. They can provide a comprehensive evaluation and determine if further surgical intervention is required.

Follow-Up Care
Post-operative care is crucial for the successful healing of a colovaginal fistula. This may include:
- Regular Follow-Up Appointments: To monitor healing and address any complications.

- Nutritional Support: Ensuring adequate nutrition can promote healing, especially if there are dietary restrictions due to the fistula.

- Psychological Support: The emotional impact of living with a colovaginal fistula can be significant, and counseling may be beneficial.

In summary, your mother-in-law's condition requires a thorough evaluation by a colorectal surgeon, with possible involvement from gynecologists and urologists. Surgical repair is often the most effective treatment for colovaginal fistulas, and a multidisciplinary approach will provide the best outcomes. It is essential to address both the physical and emotional aspects of her condition to ensure comprehensive care.
