Pelvic magnetic resonance imaging and colonoscopy showed intestinal infection with a rectal fistula, and the initial diagnosis was severely active Crohn’s disease with an enterovesical fistula. The patient had multiple internal fistulas and infections, and strongly refused surgical conditions. The patient was given an intravenous infusion of ustekinumab and somatostatin, with anti-infective treatment, nutritional support and regulation of the intestinal flora. Drainage and debridement of the cutaneous fistula were performed. After comprehensive treatment and management, the patient’s condition achieved significant clinical remission.Conclusion: This patient achieved clinical response and will receive follow-up for another dose of ustekinumab after 12 weeks. The patient developed enterovesical and enterocutaneous fistulas, the incidence of multiple fistulas which are low in patients with CD and are difficult to cure and prone to relapse. Only few patients achieve complete remission. At present, there is no standard and effective treatment for CD with multiple fistulas. Usually, surgery is performed for treatment. Drug therapy, especially with biological agents, should be selected as the first-line pre-operative treatment. Clinicians, especially gastroenterologists, need to improve their knowledge of these conditions and update the treatment consensus guidelines in a timely manner. Clinicians need to take into account the patient’s condition and willingness when developing an effective treatment plan.Keywords: Crohn’s disease, enterovesical fistula, enterocutaneous fistula, ustekinumab, therapy
