Background: Genital fistulas (GF) can arise in the course of Crohn's disease (CD), are difficult to manage and determine a significant alteration of the quality of life.
Aims: To review the joint experience of the Inflammatory Bowel Disease Units in six University Hospitals in the management of GF in Crohn's disease on female patients.
Results: A total of 47 patients with GF were identified, affecting 3.8% of women with CD treated in our centers. A 47.5% of patients were smokers. The median of time from the diagnosis of CD reached 102 months. According to anatomical type, GF were classified as rectovaginal (74.5%), anovaginal/anovulvar (21.3%) and enterovaginal (4.3%). Main symptoms were vaginal discharge of fecal material (55.3%), vaginal passage of gas (40.4%), or both. Fistulas were treated with antibiotics in 59.6% of patients, without any lasting success. Thiopurines were used in 80.9% of cases, with 13.2% of complete and 23.7% of partial responses. Anti TNF-alpha therapy was applied in 63.8%, with a 16.7% of complete and a 30% of partial responses (all responding patients received infliximab). Surgery was indicated in 38.3% of patients, with a 22% of complete responses after a first operation and 38.8% after reintervention. In all, definitive closure after one or more of these therapies was achieved in only 31.9% of cases.
Conclusion: Genital fistulas are a significant problem in female Crohn's disease patients. Therapy is not well defined and only partially effective (one in three cases). Surgical therapy stands out as the most effective treatment.
