However, radiocontrast study 6 days later revealed leakage from the primary closure site (Fig. 1A). Five days later, follow-up radiocontrast study did not reveal any leakage (Fig. 1B), and the amount of peritoneal drainage decreased to less than 15 mL/day.

Three weeks after the surgery, a radiocontrast study revealed leakage from the esophagojejunostomy, and endoscopy revealed a 1.2-cm dehiscence of the anastomosis that was located 18 cm from the incisors (Fig. 3A). Repeated endoscopic examination revealed the complete closure of the fistula 7 weeks after the insertion, and the stent was removed (Fig. 3B).
