Pelvic inflammatory disease (PID) is a common gynecological condition, some very mild and some very severe (life-threatening abscess rupture), the most common being tubal inflammation and tubo-ovarian inflammation. If not treated timely, appropriately and thoroughly, sequelae may occur, previously known as chronic pelvic inflammatory disease, manifesting as infertility (pelvic factors account for 35% of female infertility factors, most commonly pelvic inflammatory disease), tubal pregnancy (8-10 times more frequent than normal women), chronic pelvic pain (for which there is no effective treatment), and recurrent inflammatory episodes, seriously affecting women’s reproductive health and The recurrent inflammatory disease seriously affects women’s reproductive health and family harmony. The clinical symptoms of pelvic inflammatory disease vary widely (some are mild, manifesting only as increased vaginal discharge or lower abdominal discomfort. Some symptoms are more severe, with persistent lower abdominal pain, aggravated by activity or sexual intercourse, or even fever, bloating and diarrhea, nausea and vomiting, and urinary frequency and pain), and clinical diagnosis is difficult, but delayed diagnosis and treatment can lead to serious sequelae. Therefore, as long as the treatment meets the minimum diagnostic criteria (cervical pain or uterine pressure or pressure in the adnexal area) and other factors are excluded from causing lower abdominal pain, it is necessary to choose broad-spectrum, adequate antibiotic treatment based on experience, and prompt surgical treatment if the effect is not good; at the same time, attention is paid to the treatment of sexual partners (those who have been in contact within 60 days before the onset of symptoms). Clinical data show that timely treatment within 48 hours of diagnosis can significantly reduce the occurrence of sequelae. Pelvic inflammatory diseases are a group of infectious diseases of the upper female genital tract, and in addition to focusing on early standardized treatment, it is necessary to focus on preclinical primary prevention: moderate sexual intercourse, attention to sexual hygiene, maintenance of lower genital tract health, improvement of immunity, and avoidance of unnecessary history of repeated uterine surgery.
