Intensive care unit utilization and outcome after esophagectomy

Area of Science:

• Thoracic Surgery
• Critical Care Medicine
• Surgical Outcomes Research

Background:

• Esophagectomy is a complex procedure with potential for significant postoperative complications.
• Understanding the need for and outcomes of intensive care unit (ICU) admission is crucial for resource allocation and patient management.

Purpose of the Study:

• To determine the frequency of ICU admission following esophagectomy.
• To identify factors associated with ICU admission and analyze patient outcomes.

Main Methods:

• Retrospective cohort study of 432 patients undergoing esophagectomy between 2000 and 2004 at a tertiary referral center.
• Data abstraction included demographics, comorbidities, perioperative management, complications, and APACHE III scores.
• Statistical analyses compared outcomes between ICU and non-ICU patients, and survivors versus non-survivors.

Main Results:

• 123 patients (28.5%) required ICU admission, commonly for arrhythmias, new pulmonary infiltrates, or aspiration.
• ICU patients presented with high acuity (mean APACHE III score 54.5).
• Overall in-hospital mortality was 3.7%; 12.2% of ICU patients did not survive to discharge.

Conclusions:

• A substantial proportion of esophagectomy patients necessitate ICU admission, frequently for aspiration pneumonitis and arrhythmias.
• Despite high severity of illness, perioperative mortality remains low at high-volume centers.
• Early identification and management of complications are vital for improving outcomes after esophagectomy.
