Vedolizumab combined with surgical resection successfully treated perforating Crohn's disease with peritoneal space to rectal and vaginal fistulas: a case report.

Background Intestinal perforations and fistulas are common complications of Crohn's disease. However, chronic perforation with peritoneal space to rectal and vaginal fistulas have not been previously reported. Case presentation A 38-year-old female suffered from progressive lower abdominal pain, diarrhea and weight loss. Terminal ileal chronic perforation with intra-abdominal abscess, peritoneal space to rectal and vaginal fistulas were noted. The patient received surgical resection of the cecum and terminal ileum, and then vedolizumab treatment. Three months later, she had complete fistula closure, and her body mass index had increased from 13 to 22. Conclusion Vedolizumab combined with stool diversion is effective at treating Crohn's disease with chronic perforation and complex peritoneal space to rectal and vaginal fistulas.
