Introduction: Dysphagia in old patients secondary to diffuse idiopathic skeletal hyperostosis (DISH) syndrome is underdiagnosed. Surgical resection of the offending osteophytes is the definitive treatment. However, the timing of surgery in the course of the disease is still controversial. The study tries to find a correlation if any, between the timing of osteophytectomy surgery aimed to relieve DISH syndrome-induced dysphagia and the surgical outcome. Methods: During the period from 2010 to 2015, clinical and radiological data of patients who presented with dysphagia attributed to DISH syndrome were retrospectively reviewed along with their management and outcome. Results: One female and seven male patients were included in the study. Mean age was 71 years. Mean duration of dysphagia was 3 years and 10 months. Surgical resection was attempted through anterolateral cervical approach in five cases who were fit for surgery, in which four showed complete resolution of dysphagia (one experienced transient hoarseness of voice for 4 weeks postoperatively), and the fifth showed minimal improvement after limited resection due to intraoperative finding of marked esophageal adherence to osteophytes. The two unfavorable outcomes (subtotal resection and transient hoarseness of voice) occurred in relatively older patients (average: 75.5 years) with longer standing dysphagia (average: 7 years). Conclusion: DISH syndrome as a cause of dysphagia is commonly underlooked. Surgical resection of the offending osteophytes through an anterolateral approach is a safe and effective procedure. For patients who are fit for surgery, older age or longer duration of dysphagia might be associated with less favorable surgical outcome.
