Methods The clinical data of 16 patients with postoperative upper gastrointestinal malignancies treated in our hospital from January 2018 to June 2022 were retrospectively analyzed. Results All the 16 patients successfully completed the operation,and no perioperative death occurred.The cumulative length of hospitalization was 18-38 days.After operation,2 cases of pulmonary infection,1 case of respiratory failure,and 1 case of cervical anastomotic fistula were cured after conservative treatment.All patients could eat normally during postoperative follow-up,and no tumor recurrence and metastasis was found. Conclusion For patients with recurrent upper gastrointestinal cancer after esophageal cancer surgery,if the lesion is relatively limited,surgical treatment is reliable and an optional treatment plan.
