Presentation
History of operated perforated appendicitis three months ago
Patient Data
CT enterocolonography & fistulography
An opacified branching fistulous track is seen extending intra-abdominally to reach the cecum following positive contrast administration through the parietal opening at the appendectomy scar with minimal pericaecal fat stranding. No related intra-abdominal fluid collections detected.
Case Discussion
The patient had surgery for perforated appendicitis three months ago. He then developed dehiscence of his surgical wound with a foul smelling discharge. Colocutaneous fistula is a rare complication following appendectomy. It also can occur due to diverticulitis, Crohn disease or after colonic surgery. It may coexist with a colovaginal or colovesical fistula.
