Pelvic inflammatory disease: medical treatment.

Pelvic inflammatory disease (PID) refers to infection of the uterus (endometritis), fallopian tubes (salpingitis) and adjacent pelvic structures (tubo-ovarain complex, pelvic peritonitis). PID causes major medical, social, and economic problems. Long-term sequelae, especially tubal factor infertility and extra uterine pregnancy are common and their management is extremely costly. Medical treatment of PID should be immediate because sequelae are more frequent if the treatment is delayed or inadequate.
