From the Guidelines
Rectovaginal fistulas have significant implications on a patient's quality of life, including fecal incontinence, recurrent vaginal infections, and psychological distress, and therefore, require prompt and effective management, with surgical repair being the primary treatment option, as supported by the most recent guidelines 1. The main implications of a rectovaginal fistula include:
- Fecal incontinence through the vagina
- Recurrent vaginal infections
- Unpleasant odor
- Painful intercourse
- Psychological distress, including depression, anxiety, and social isolation
- Skin irritation and breakdown in the perineal and vaginal areas due to constant fecal contamination According to the ECCO guidelines on therapeutics in Crohn's disease, surgical treatment is recommended for selected patients with rectovaginal fistulas, and medical treatment with anti-TNF agents, such as infliximab, may be effective in achieving prolonged closure of the fistula 1. A post hoc analysis of the ACCENT II study found that infliximab was more effective than placebo in achieving prolonged closure of rectovaginal fistulas, with 54.5% to 90.0% of fistulas closing in the infliximab maintenance group compared to 28.6% to 42.9% in the placebo group 1. Surgical repair of rectovaginal fistulas is the primary treatment option, with techniques depending on the size, location, and underlying cause of the fistula, and patients should be managed by an experienced multidisciplinary team to optimize their quality of life 1. Before surgery, controlling infection and inflammation is essential, which may involve antibiotics, sitz baths, and proper hygiene, and some patients may temporarily need a diverting colostomy to allow the repaired area to heal properly 1. Recovery typically requires 6-8 weeks of restricted activity, avoiding sexual intercourse, and maintaining soft stools through dietary modifications and stool softeners, and the success rate for surgical repair varies from 70-90%, depending on the complexity of the fistula and the patient's overall health status.
From the Research
Implications of Rectovaginal Fistula
The implications of a rectovaginal fistula (RVF) are significant and can have a substantial impact on a patient's quality of life. Some of the key implications include:
- Reduced quality of life: RVF can cause debilitating symptoms, including fecal incontinence, vaginal discharge, and pelvic pain, which can severely impact a patient's daily life and well-being 2, 3, 4, 5, 6.
- Emotional and psychological distress: The embarrassing and irritating symptoms of RVF can cause significant emotional and psychological distress, including anxiety, depression, and loss of self-esteem 2, 3, 4, 5, 6.
- Management challenges: RVF can be challenging to manage, and treatment options may have varying degrees of success, which can be frustrating for both patients and healthcare providers 2, 3, 4, 5, 6.
- Impact on sexual function: RVF can also impact sexual function, with some patients experiencing impairment of sexual function after treatment 4.
- Need for individualized treatment: Due to the complexity and variability of RVF, individualized treatment approaches are often necessary, taking into account factors such as the size, location, and etiology of the fistula, as well as the patient's overall health and medical history 2, 3, 4, 5, 6.
Factors Influencing Management
Several factors can influence the management of RVF, including:
- Size and location of the fistula: The size and location of the fistula can impact the choice of treatment, with larger or more complex fistulas often requiring more invasive procedures 3, 5, 6.
- Etiology: The underlying cause of the fistula, such as Crohn's disease or diverticulitis, can also impact treatment choices 2, 3, 5.
- Presence of inflammation or infection: The presence of inflammation or infection can require initial treatment with conservative measures, such as antibiotics or anti-inflammatory medications, before surgical intervention can be considered 5.
- Patient's overall health: The patient's overall health, including the presence of comorbidities, can also impact treatment choices and outcomes 5.
