Сase study of ulcerative colitis complicated by colocutaneus fistula

Abstract

Background. Ulcerative colitis (UC) is a multifactorial chronic inflammatory bowel disease characterized by such symptoms as abdominal pain, diarrhea, and rectal bleeding. One of the complications of UC is the formation of fistulas with the bladder, vagina, perineum, and other structures. Objective. To present a clinical case of ulcerative colitis complicated by colocutaneous fistula. Material and Methods. Clinical observation data of a 68-year-old man having been treated in the Purulent Surgery Department of the Grodno University Clinic. Results. The patient, with a low body mass index (17.1 kg/m²), was admitted for leakage of intestinal contents from postoperative scar (with a history of a midline laparotomy for intestinal obstruction with creation of a loop ileostomy). Imaging confirmed a fistula to the sigmoid colon, and colonoscopy revealed erosive proctosigmoiditis. A left-sided hemicolectomy was performed. Histological findings were consistent with ulcerative colitis. Postoperatively, an abdominal abscess developed, which was successfully treated with drainage. Conclusion. The case illustrates the complexities of UC management and its multifactorial nature.
