Pelvic inflammatory disease is one of the common gynecological diseases, which generally refers to inflammation and injury of the upper genital tract, including adnexitis, pelvic peritonitis, pelvic connective tissue inflammation, pelvic abscess, and pelvic thrombophlebitis. The pelvic inflammatory disease is divided into acute pelvic inflammatory disease and chronic pelvic inflammatory disease, which has a high incidence and is prone to recurrent attacks, affecting women’s health. The clinical diagnosis of acute pelvic inflammatory disease must have the following three criteria: ① lower abdominal pressure pain with or without rebound pain; ② cervical or uterine body lifting pain or swaying pain; ③ adnexal area pressure pain. The following indicators can increase the specificity of diagnosis: ① positive culture of cervical secretion or Gram smear for N. gonorrhoeae or Chlamydia trachomatis; ② temperature >38℃; ③ blood leukocytes >10×109/L; ④ pus extracted by posterior vault aspiration; ⑤ pelvic abscess or inflammatory mass found by double diagnosis or ultrasound examination. The diagnosis of chronic pelvic inflammatory disease is mostly due to the prolonged course of the disease after regular and effective treatment at the end of the acute period, but there are also those who have a slow onset and no obvious sexual history. The patient often has a history of acute inflammation and recurrent attacks, secondary infertility, irregular menstruation, dull pain in the lower abdomen, and lower abdominal pain that is aggravated by menstruation or intercourse. Ultrasound is valuable for diagnosing chronic pelvic inflammatory disease, and laparoscopy is of confirmatory significance. 3. Treatment: Chinese herbal medicine, enema and external application are very effective in treating pelvic inflammatory disease.
