Boerhaave Syndrome (Esophageal Perforation) — NPO, Broad Antibiotics, and Surgical Control

System: General Surgery • Reviewed: Sep 1, 2025 • Step 1Step 2Step 3

Synopsis:

Full‑thickness esophageal rupture after forceful emesis presents with chest/epigastric pain and subcutaneous emphysema. Diagnose with CT contrast esophagram; keep NPO, start broad‑spectrum antibiotics and antifungals, and obtain surgical/endoscopic repair with drainage.

Key Points

  • Use the highest‑yield diagnostic test early; do not let testing delay time‑critical therapy.
  • Set objective targets (hemodynamic, neurologic, respiratory) and reassess frequently.
  • Plan definitive source control or disease‑specific therapy when indicated; document follow‑up and patient education.

Algorithm

  1. Suspect after forceful emesis or instrumentation with chest pain; obtain CT with contrast.
  2. Keep NPO; start broad antibiotics (± antifungals); consult surgery/GI early.
  3. Definitive control: primary repair or endoscopic stent ± drainage based on timing and contamination.
  4. ICU monitoring; nutritional support; follow‑up imaging to confirm healing.

Clinical Synopsis & Reasoning

Full‑thickness esophageal rupture after forceful emesis presents with chest/epigastric pain and subcutaneous emphysema. Diagnose with CT contrast esophagram; keep NPO, start broad‑spectrum antibiotics and antifungals, and obtain surgical/endoscopic repair with drainage.


Treatment Strategy & Disposition

Stabilize ABCs. Initiate guideline‑concordant first‑line therapy with precise dosing and continuous monitoring. Escalate to advanced/procedural interventions based on explicit failure criteria. Define ICU, step‑down, and ward disposition triggers; involve specialty teams early.


Epidemiology / Risk Factors

  • Risk varies by comorbidity and precipitants; see citations for condition‑specific data.

Prognosis / Complications

  • Outcome depends on timeliness of diagnosis and definitive therapy; monitor for complications.

Patient Education / Counseling

  • Provide red‑flag education, adherence guidance, and explicit return precautions; arrange timely specialty follow‑up.
