Cutaneous fistula may develop spontaneously as a complication of an perforating appendicitis. However, intestinal fistula caused by parasites is a rare report.
In the operation, we found that expanded appendix was perforated from its distal part and was fistulized to the right lateral abdominal wall. The complications of postoperative was intestinal fistula. Colonoscopy was performed revealing some nematode around the appendiceal orifice. The development of fistula after bowel resection and anastomosis can be devastating. Immediate drainage and establishment of enteral nutrition can lead to spontaneous healing of fistula.
Testing for nematode infection in a patient with suspected appendicitis is not routine, it still stands as a challenge in clinical practice. In view of this situation, killing parasites is necessary, otherwise it is difficult to cure.
