Complex Esophageal Reconstruction Procedures Have Acceptable Outcomes Compared With Routine Esophagectomy

Area of Science:

• Gastroenterology
• Surgical Oncology
• Thoracic Surgery

Background:

• Complex esophageal reconstruction (CER) involves restoring esophageal continuity in challenging surgical fields, often using non-gastric conduits or after prior esophageal diversion.
• Non-complex esophageal reconstruction (NCER) utilizes an undisturbed stomach for reconstruction, serving as a comparative baseline.

Purpose of the Study:

• To compare the outcomes of complex esophageal reconstruction (CER) with non-complex esophageal reconstruction (NCER).
• To evaluate differences in complications, reoperation rates, and survival between CER and NCER.

Main Methods:

• A retrospective cohort study of 75 CER cases and 75 NCER cases (1995-2014) matched for cancer versus benign disease.
• Analysis included demographic characteristics, comorbidities, complications, and survival using logistic regression, Kaplan-Meier, and Cox proportional hazards regression.

Main Results:

• CER patients experienced significantly higher rates of reoperation, pneumonia, infection, and gastrointestinal complications, along with a longer median length of stay.
• Despite increased complications, 30-day, 90-day, and overall survival rates were not statistically different between CER and NCER groups.
• A higher proportion of non-white patients underwent CER, and disease types differed significantly between groups (p < 0.01).

Conclusions:

• Complex esophageal reconstruction (CER) is associated with increased postoperative complications and extended hospital stays compared to non-complex esophageal reconstruction (NCER).
• Survival outcomes at 30 days, 90 days, and overall are comparable between CER and NCER.
• CER can be considered a safe and effective option for patients with acceptable risks and anticipated long-term survival.
