This is an epidemiological study of 1,498 patients who underwent laparoscop
ic surgery for different reasons. Between 1989 and 1996, 308 cases of endom
etriosis were identified among 1,498 patients who underwent laparoscopic su
rgery. One hundred and five patients were admitted for pelvic pain, 794 for
infertility, 319 patients had both on admission, and 280 were admitted for
non-gynecologic complaints. The incidence of endometriosis is related to t
he chief complaint on admission. This disease has different clinical manife
stations, different locations and different stages. The mean age in our ser
ies is greater than that reported by the literature. The symptoms are relat
ed to the location of the lesions but not the stage of the disease. Unlike
pelvic pain, infertility is correlated to the stages of the disease. (C) 19
