Etiological and clinical profiles of patients with dysphagia: A teaching institution experience

Background: Dysphagia can involve any structure from the mouth to the lower esophageal sphincter. The etiologies vary from benign causes to malignant lesions. There is dearth of data regarding dysphagia in our population. Methods: A total of 208 patients with complaints of dysphagia were screened for the study. After ruling out neurological/local oropharyngeal causes of dysphagia, 200 patients with suspected esophageal dysphagia (ED) were recruited in the study. Dysphagia was graded as per the dysphagia scoring system. All patients underwent upper gastro-intestinal endoscopy and were evaluated for the presence of mechanical and non-mechanical causes of ED. Results: The mean age of patients with dysphagia was 53.8 ± 15.4 years. with males and females being 82 and 118, respectively. The mean duration of the symptom was 7.2 ± 10.6 months (median 3 months). Ninety-eight patients (49%) having dysphagia were in the age group of 56–65 years. The dysphagia score was 0 among 58, and 4 among 26 subjects. Foreign body sensation was the most frequent chief complaint in 90 (45%) patients. Ninety-six (48%) and 104 (52%) patients had mechanical and non-mechanical causes of dysphagia, respectively. Among mechanical causes of dysphagia, 68 patients (70.8%) had esophageal growth and 28 (29.2%) had esophageal stricture. Sixty-seven patients had squamous cell carcinoma. Among non-mechanical causes, 50 (48.1%) had globus sensation, 24 (23.1%) had hiatus hernia, and 16 (15.4%) functional dysphagia. Conclusion: Dysphagia is a common problem with varied etiologies. The esophageal growth and globus sensation are among the predominant causes of ED. We stress that all patients of dysphagia must be meticulously investigated.
