Introduction Anterior cervical fusion has been performed safely and effectively for decades for the treatment of multiple pathologies, with low rates of morbidity and mortality. Esophageal perforation is a rare but potentially serious complication of anterior cervical spine approaches. There is no consensus regarding the best treatment strategies for this complication. Objectives To determine the prevalence of esophageal perforation following anterior cervical fusion in a single institution and to describe two cases of this complication that were treated with primary repair. Methods We retrospectively analyzed all consecutive patients who underwent anterior cervical fusion in a single private institution from January 1999 to August 2017. Patients who developed esophageal perforation per- or postoperatively were included in the analysis. Results A total of 830 anterior cervical fusion surgeries were performed during the analyzed period. Two cases (0.24%), both of male patients, were complicated by esophageal perforation, one intraoperatively and the other four years after the first surgery. Both patients were treated with primary esophageal repair, and good outcomes were obtained. Conclusion Primary repair is a therapeutic option in cases of esophageal perforation after anterior cervical fusion. Satisfactory results were obtained in both cases. Further studies are necessary to elucidate the best therapeutic options for this rare complication.
