Complicated enteroenteric intestinal fistula due to Crohn's disease: a rare case report

Crohn's disease can lead to complications such as fistula formation, with ileosigmoid fistulas being common. This case report presents a 54-year-old male with Crohn's disease, who had abdominal pain, diarrhea, and weight loss. He had a history of miliary tuberculosis, which complicated the diagnostic process. Imaging revealed fistulas and thickening in the terminal ileum, while surgery included ileocecectomy, fistulectomy, and repair of affected areas. The patient recovered without complications. This case highlights the diagnostic challenges when Crohn's disease coexists with infectious diseases like tuberculosis and underscores the importance of accurate imaging and a multidisciplinary approach for diagnosis and treatment.
