[Appendico-vesical fistula secondary to acute appendicitis. Review of the literature].

Acute appendicitis, particularly pelvic, may cause a suppurative process that spontaneously drains to the bladder and an appendicovesical fistula may result. The pelvic appendix and the bladder may occasionally become fused in an inflammatory and necrotic focus, directly creating a fistula. A case of vesicointestinal fistula secondary to appendiceal pelvic peritonitis is described and the cases reported in the literature are reviewed.
