DEFINITION
INFLAMTION OF UPPER GENITAL TRACT ENVOLVING with ascending infection from lower
genital tract including
endocervix
- Endometris
- Salpingitis
- Oophritis
- Parametritis
- Pelvic peritonitis
Introduction
Delays of only a few days in receiving appropriate treatment markedly increase the risk of sequelae, which include:
- Infertility,
- Ectopic pregnancy and
- Chronic pelvic pain.
AETIOLOGY
While sexually transmitted infections such as :
- Chlamydia trachomatis and
- Neisseria gonorrhoeae have been identified as causative agents,
- Mycoplasma genitalium,
- Anaerobes and other organisms may also be implicated.
RISK FACTORS
- Early age of sexual activity
- Multiple sex partners
- Sex workers
- Use of immune suppressant drugs
- Infection with HIV
- Drug abuse
- Alcoholics
- Gynecological procedures like D/Cs
CLINICAL FEATURES
Symptoms
Pain lower abdomen bilateral
Fever (38.4)
Vaginal discharge
Dyspareunia
Menorrhagia
SIGNS
Increase temperature
Tachycardia
Abdominal tenderness/rebound tenderness
Abnormal discharge per vaginum
Fornicial tenderness
Cervical motion tenderness
INVESTIGATIONS
- Blood :- Hb,TCDC,ESR,Sugar,Urea, grRh,CRP
- Urine
- Endocervical Swab for Gm stain and culture, WBC count.
- Endometrial biopsy
- USG- Abdominal and vaginal
- Laparoscopy, peritoneal fluid culture (Gold standard)
- Laparotomy
CDC CRITERIA
Minimum
- Cervical motion tenderness
- Adnexal tenderness and uterine tenderness
- WBCs on wet mount of discharge
Additional
- Fever (> 38°4C)
- Abnormal discharge
- Raised ESR
- C reactive protein
- Culture positive swab
Definitive criteria
- Histopathologic evidence of endometritis on endometrial biopsy
- Transvaginal sonography or magnetic resonance imaging techniques showing thickened, fluid-filled tubes with or without free pelvic fluid or tubo-ovarian complex
- Laparoscopic abnormalities consistent with PID
Classification
- Acute
- Chronic
Clinical diagnosis
Laparoscopy :
Enables specimens to be taken from the fallopian tubes and the pouch of Douglas and
Can provide information on the severity of the condition.
Although Laparoscopy has been considered the gold standard in many studies of treatment regimens, 15–30% of suspected cases may have no laparoscopic evidence of acute infection.
When there is diagnostic doubt, however, laparoscopy may be useful to exclude alternative pathologies.
Transvaginal ultrasound scanning may be helpful where there is diagnostic difficulty.
When supported by power Doppler it can identify inflamed and dilated tubes and tubo -ovarian masses, but there is insufficient evidence to support its routine use.

Oral treatment
Recommended Regimen A
Levofloxacin 500 mg orally once daily for 14 days* OR Ofloxacin 400 mg orally twice daily for 14 days* WITH OR WITHOUT Metronidazole 500 mg orally twice a day for 14 days
Regimen B
Ceftriaxone 250 mg IM in a single dose PLUS Doxycycline 100 mg orally twice a day for 14 days WITH OR WITHOUT Metronidazole 500 mg orally twice a day for 14 days
Oral Regimen B
Cefoxitin 2 g IM in a single dose and Probenecid, 1 g orally administered concurrently in a single dose PLUS Doxycycline 100 mg orally twice a day for 14 days WITH OR WITHOUT Metronidazole 500 mg orally twice a day for 14 days
Other parenteral third-generation cephalosporin (e.g., ceftizoxime or cefotaxime) PLUS Doxycycline 100 mg orally twice a day for 14 days WITH OR WITHOUT Metronidazole 500 mg orally twice a day for 14 days
Inpatient treatment
Recommended Parenteral Regimen A
Cefotetan 2 g IV every 12 hours OR Cefoxitin 2 g IV every 6 hours PLUS Doxycycline 100 mg orally or IV every 12 hours
Alternative parental Inpatient regimens
Levofloxacin 500 mg IV once daily* WITH OR WITHOUT Metronidazole 500 mg IV every 8 hours
OR Ofloxacin 400 mg IV every 12 hours* WITH OR WITHOUT Metronidazole 500 mg IV every 8 hours
OR Ampicillin/Sulbactam 3 g IV every 6 hours PLUS Doxycycline 100 mg orally or IV every 12 hours
Inpatient treatment
Admission to hospital would be appropriate in the following circumstances:
- Surgical emergency cannot be excluded
- Clinically severe disease
- Tuboovarian abscess
- PID in pregnancy
- Lack of response to oral therapy
- Intolerance to oral therapy.
In more severe cases inpatient antibiotic treatment should be based on intravenous therapy, which should be continued until 24 hours after clinical improvement and followed by oral therapy.
Treatment in pregnancy
A pregnancy test should be performed in all women suspected of having PID to help exclude an ectopic pregnancy.
Treatment in a woman with an intrauterine contraceptive device
An intrauterine contraceptive device (IUCD) may be left in situ in women with clinically mild PID but should be removed in cases of severe disease.
Other modes of treatment
Surgical treatment should be considered in :
- Severe cases or
- Where there is clear evidence of a pelvic abscess.
- Failure of medical treatment
Laparotomy/laparoscopy may help early resolution of the disease by division of adhesions and drainage of pelvic abscesses.
Culdotomy
Ultrasound-guided aspiration of pelvic fluid collections is less invasive and may be equally effective.
- If adequate screening for gonorrhoea and chlamydia in the sexual partner(s) is not possible, empirical therapy for both gonorrhoea and chlamydia should be given.
- Referral of the index patient and her partner to a genitourinary medicine clinic is recommended, to facilitate contact tracing and infection screening.
Women who are infected with HIV
Women with PID who are also infected with HIV should be treated with the same antibiotic regimens as women who are HIV negative.
