Enterovesical fistula and intestinal obstruction by ileal endometriosis.

Endometriosis is one of the most common gynecological diseases, is characterized by the presence of endometrial tissue outside the uterine cavity in women of reproductive age or perimenopausal. Endometriosis “infiltrative in depth” is defined as one that penetrates more than 5 mm in the affected tissue, occurs in one third of all cases and is usually located in pelvic structures. At ileum is very rare, 1-7 % of cases of intestinal involvement, with series and case reports in which the common denominator is usually a result of intestinal obstruction in the same (1,2). Perforation is even stranger and we have not found any published case that has caused enterovesical fistula as presented.
