Background

  • 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

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)

Differential Diagnosis

Pelvic Pain

Pelvic origin

Abdominal origin

Evaluation

Work-Up

  • Urine pregnancy
  • Wet mount
  • Endocervical swab (for GC, Chlamydia)
  • CBC
  • ESR/CRP
  • Urine culture, analysis (to exclude UTI)

Imaging

  • Pelvic U/S
    • Ultrasound sensitivity may be as low as 56% and specificity of 85% [1]
  • CT

CDC Empiric Diagnosis Criteria[2]

  • 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
    • Pesence 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

Treat all partners who had sex with patient during previous 60 days prior to symptom onset

Outpatient Options

Alternative Outpatient Options

Inpatient

IUD

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

Disposition

Admit

Discharge

  • 72hr follow up
  • Instruct patient to abstain from sex or adhere strictly to condom use until symptoms have abated
