A 19-year-old woman comes to the emergency department complaining of sudden-onset, sharp right upper quadrant abdominal pain that worsens with deep inspiration. She also reports a 5-day history of lower pelvic discomfort and spotting between her menstrual periods. She recently became sexually active with a new male partner. Her only medication is an oral contraceptive. Her temperature is 38.3°C (101.0°F), blood pressure is 112/68 mmHg, pulse is 98/min, and respirations are 18/min. Physical examination shows marked right upper quadrant tenderness without guarding or rebound. Murphy sign is negative. There is also bilateral lower quadrant tenderness. Pelvic examination reveals a mucopurulent cervical discharge and pronounced cervical motion tenderness.

Laboratory testing reveals:
TestValue
Leukocyte count12,500/mm³
Aspartate aminotransferase (AST)28 U/L
Alanine aminotransferase (ALT)24 U/L
Alkaline phosphatase65 U/L
Total bilirubin0.9 mg/dL

A urine pregnancy test is negative. Right upper quadrant ultrasound demonstrates a normal gallbladder without stones, sludge, or wall thickening.

Which of the following is the most appropriate next step in management?

  1. A
    Obtain a computed tomography scan of the abdomen and pelvis
  2. Administer intramuscular ceftriaxone, oral doxycycline, and oral metronidazoleCevap
  3. C
    Admit for intravenous piperacillin-tazobactam and surgical consultation
  4. D
    Administer oral levofloxacin and oral metronidazole
  5. E
    Request a hepatobiliary iminodiacetic acid scan

Cevap

The correct answer is to administer intramuscular ceftriaxone, oral doxycycline, and oral metronidazole.
The correct action is to administer intramuscular ceftriaxone, oral doxycycline, and oral metronidazole. This patient's presentation of fever, lower pelvic pain, cervical motion tenderness, and mucopurulent discharge is diagnostic for pelvic inflammatory disease (PID). Her concurrent pleuritic right upper quadrant pain, combined with a normal right upper quadrant ultrasound and normal liver transaminases, is classic for Fitz-Hugh-Curtis syndrome (perihepatitis). This is a well-known complication of PID caused by the ascending spread of infection (typically *Neisseria gonorrhoeae* or *Chlamydia trachomatis*) along the right paracolic gutter to the liver capsule. The diagnosis is clinical, and surgical intervention or advanced imaging is not required. Because the patient is hemodynamically stable and lacks indications for hospitalization, outpatient management is appropriate. The updated CDC guidelines mandate the addition of oral metronidazole to the standard intramuscular ceftriaxone and oral doxycycline regimen to provide enhanced anaerobic coverage.

Adım Adım Çözüm

1
Analyze the clinical presentation, including the pelvic exam findings and vital signs.
The patient is a sexually active female with fever, lower abdominal pain, cervical motion tenderness, and mucopurulent discharge, which establishes the diagnosis of Pelvic Inflammatory Disease (PID).
Identifying the primary pelvic infection is necessary before explaining the right upper quadrant symptoms.
2
Evaluate the cause of the pleuritic right upper quadrant pain in the context of the laboratory and ultrasound results.
The normal right upper quadrant ultrasound and normal liver transaminases rule out acute cholecystitis and primary hepatitis. The pain is caused by Fitz-Hugh-Curtis syndrome (perihepatitis).
Fitz-Hugh-Curtis syndrome is a classic complication of PID caused by the ascending spread of infection to the liver capsule.
3
Determine the appropriate setting and pharmacological regimen based on current guidelines.
Because the patient is hemodynamically stable and tolerating oral intake, outpatient management is appropriate. The updated regimen requires intramuscular ceftriaxone, oral doxycycline, and oral metronidazole.
Guidelines mandate the addition of metronidazole to the standard ceftriaxone/doxycycline regimen to ensure adequate anaerobic coverage.

Anahtar Kavram

Fitz-Hugh-Curtis syndrome (perihepatitis) is a complication of pelvic inflammatory disease presenting with pleuritic right upper quadrant pain. It is diagnosed clinically and treated with the standard PID antimicrobial regimen (ceftriaxone, doxycycline, and metronidazole).
