Clinical Scorecard: Impact of Patient Factors, Intraoperative Fluid Management, and Vasopressor Use on Anastomotic Leakage Following Ivor-Lewis Esophagectomy: A Retrospective Cohort Study from a Single Institution

At a Glance

Key Highlights

• Anastomotic leak rates range from 9–11% in contemporary cohorts, associated with increased morbidity, mortality, and healthcare utilization.
• Risk factors include poor nutritional status, comorbidities (diabetes, cardiovascular disease), neoadjuvant therapy, and technical surgical factors.
• Individualized, goal-directed intraoperative fluid management and vasopressor strategies may reduce AL incidence compared to liberal fluid replacement.

Guideline-Based Recommendations

Diagnosis

• Define anastomotic leak by radiographic contrast examination and endoscopic evaluation.

Management

• Employ individualized, goal-directed fluid therapy guided by continuous hemodynamic monitoring (e.g., FloTrac EV1000 system).
• Consider intraoperative vasopressor selection carefully due to potential effects on conduit perfusion.

Monitoring & Follow-up

• Use continuous arterial waveform monitoring for blood pressure and cardiac index during surgery.
• Monitor perioperative cumulative fluid balance from intraoperative period through postoperative day 7.

Risks

• Recognize that liberal fluid administration and inappropriate vasopressor use may increase AL risk.
• Account for patient comorbidities and preoperative antiplatelet therapy as markers of vascular risk.

Patient & Prescribing Data

Patients undergoing Ivor-Lewis esophagectomy with varied comorbidities and medication profiles including antiplatelet and cardiovascular drugs.

Preoperative use of antiplatelet agents (aspirin, P2Y12 inhibitors) may indicate higher risk of microcirculatory compromise affecting anastomotic healing.

Clinical Best Practices

• Perform thorough preoperative assessment including comorbidities, nutritional status, and medication review.
• Implement goal-directed intraoperative fluid management using advanced hemodynamic monitoring.
• Carefully select and dose vasopressors to minimize splanchnic vasoconstriction and preserve conduit perfusion.
• Utilize intraoperative perfusion assessment techniques such as indocyanine green fluorescence imaging when available.
• Adhere to standardized definitions and diagnostic protocols for anastomotic leak to ensure accurate detection and reporting.
