Appendicovesical fistula.

In this study, a case of appendicovesical fistula is introduced, a really uncommon complication of acute appendicitis. This special case joins the other 102 cases which have already been described in the international literature. Due to the mild and ambiguous symptomatology, the diagnosis of this kind of fistula is difficult to be confirmed, although a serious suspicion of a vesicointestinal communication does exist. Exploratory laparotomy is usually diagnostic and leads to decisive therapy. A brief review of this clinical entity is also included.
