Management and Outcomes of Anastomotic Leakage after McKeown Esophagectomy: A Retrospective Analysis of 749 Consecutive Patients with Esophageal Cancer

Abstract Purpose Cervical anastomotic leakages may manifest either cervically or intrathoracically. We retrospectively investigated the management strategies and clinical outcomes of patients who developed anastomotic leakages after McKeown esophagectomy and the spectrum of its clinical manifestations. Methods Patients with esophageal cancer who underwent McKeown esophagectomy with cervical anastomosis (n = 749) between January 2015 and December 2018 were included. Results Cervical anastomosis leakage was diagnosed in 53/749 (7.3%) patients. The leakage was primarily limited to cervical region in 16 (30.2%) patients, whereas intrathoracic spread was present in 37 (69.8%) patients. Intrathoracic manifestations were more commonly accompanied by fever (75.7% vs. 18.8%, P  Conclusion Intrathoracic manifestations of cervical anastomotic leakage are common in patients after McKeown esophagectomy. However, they are diagnosed later and are associated with more severe clinical consequences than cervical manifestations. Thus, a high index of suspicion and an early intervention policy for such anastomotic leaks should be adopted and strengthened to decrease the incidence of adverse clinical outcomes.
