Objective: To investigate the perioperative safety and survival benefits of two-stage operation in the treatment of esophageal malignancies. Methods: This is a retrospective case series study. The clinical data of 70 patients who underwent two-stage operation for esophageal malignancies from January 2015 to January 2023 in the Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. There were 58 males and 12 females. The age (M(IQR)) was 61 (22) years (range: 9 to 79 years), and 51.4% (36/70) of the patients were older than 65 years. All patients underwent the first operation to remove esophageal tumor and the second operation to complete digestive tract reconstruction. The reasons for two-stage operation were summarized, complications and treatment results were recorded, and the prognosis was calculated using Kaplan-Meier curve. Results: The interval between the two stages was 49 (35) days (range: 32 to 82 days). The follow-up perrod was 28(50) months (range: 1 to 69 months). The 30-day fatality rate after the first operation was 4.3% (3/70) and the 30-day fatality rate after the second operation was 0(0/63). The total complication rate of first operation was 55.7% (39/70), the respiratory complication rate was 10.0% (7/70) and the cardiovascular complication rate was 5.7% (4/70) The incidence of anastomotic leakage was 11.1% (9/63). The overall survival rate at 2, 3 and 5 years was 35.7%, 30.0% and 15.7%, respectively. Conclusion: Two-stage operation in the treatment of complex esophageal malignancies is feasible and yields satisfaetory results.
