Background

Pelvic anatomy.
  • Pelvic Inflammatory Disease (PID) comprises spectrum of infections of the upper reproductive tract:
  • It is the most common serious infection in women aged 16 to 25 years and begins as cervicitis (commonly due to GC or chlamydia) that may progress to polymicrobial infection.
    • Initial lower tract infection may be asymptomatic
    • Most common cause of death is rupture of a tubo-ovarian abscess
    • Can be caused by organisms such as M. genitalium which is very difficult to isolate and will not be picked up on routine testing
  • Bilateral tubal ligation does not confer protection against risk[1]

Risk factors[2]

  • Age < 25
  • Age at first sexual intercourse < 20
  • Non-white ethnicity
  • Nulliparous
  • History of transmitted diseases, especially chlamydia
  • IUD within 21 days after insertion[3]

Clinical Features

History

Physical Exam

  • Cervical motion tenderness
  • Adnexal tenderness (Most sensitive finding - Sn ~95%)
  • Mucopurulent cervicitis
    • Absence should prompt consideration of another diagnosis
  • RUQ Pain
    • May indicate perihepatic inflammation (particularly if jaundice also present)


Complications

Differential Diagnosis

Acute Pelvic Pain

Differential diagnosis of acute pelvic pain

Gynecologic/Obstetric

Genitourinary

Gastrointestinal

Musculoskeletal

Vascular

Evaluation

PID with pyosalpinx on transvaginal ultrasound: bilateral adenexal cysts consistent with pyosalpinges (white arrows).
PID on CT with bilateral adnexal complex fluid-filled and thick-walled cysts typical for tubo-ovarian abcess formation and an associated ileus.

Workup

  • Urine pregnancy
  • Wet mount
  • Endocervical swab (for GC, Chlamydia)
  • CBC
  • ESR/CRP
  • Urine culture, analysis (to exclude UTI)
  • Pelvic ultrasound
    • Ultrasound sensitivity may be as low as 56% and specificity of 85% [5]
  • CT

CDC Empiric Diagnosis Criteria[6]

  • Woman at risk for STIs
  • Pelvic or lower abdominal pain
  • No cause for the illness other than PID can be identified
  • At least one of the following on pelvic exam:
    • CMT
    • Uterine tenderness
    • Adnexal tenderness.
  • Additional criteria that make the diagnosis more likely:
    • Oral temperature >101° F (>38.3° C)
    • Abnormal cervical or vaginal mucopurulent discharge
    • Presence of abundant numbers of WBC on saline microscopy of vaginal fluid
    • Elevated ESR
    • Elevated CRP
    • Laboratory documentation of cervical infection with GC or chlamydia

Management

Antibiotics

  • No sexual activity for 2 weeks;
  • Treat all partners who had sex with patient during previous 60 days prior to symptom onset

Outpatient Antibiotic Options

Inpatient Antibiotic Options

IUD

  • No change in treatment if IUD in place (may treat without removal)


Due to inability to test for all causative pathogens and the potential for serious complications such as infertility, the CDC has made this a purposefully vague condition with a low threshold for empiric treatment

Disposition

Admit

Discharge

  • 72hr follow up
  • Instruct patient to abstain from sex or adhere strictly to condom use until partner treatment and symptoms have abated
  • HIV+ is not an automatic criteria for admission, consider overall clinical impression
