Clinical profile of patients presenting with dysphagia - an experience from a tertiary care center in North India.

BACKGROUND AND AIM: Dysphagia can lead to substantial morbidity and mortality, especially in the elderly. It has both benign and malignant causes. Despite having a varied etiology, there have been few studies in India. Therefore, a study was undertaken to evaluate the clinical profile and various etiologies of dysphagia.

METHODS

A prospective study was conducted on 220 patients with a complaint of dysphagia. Detailed history and examination, endoscopy and biopsies, and barium swallow were performed. Computed tomography and magnetic resonance imaging were performed wherever required. Patients who had an oropharyngeal or neurological cause of dysphagia were excluded.

RESULTS

The mean age of patients was 57.2 years, with the male: female ratio being 1.7:1. Of the patients, 35% (78 patients) had malignant etiology, with a mean age of 65.2 years, and 65% (142 patients) had a benign etiology, with a mean age of 51 years. Among the patients with malignancy, 56 had squamous cell carcinoma of esophagus (71.7%), 20 had adenocarcinoma of esophagus (25.7%), and 2 had gastric cardia adenocarcinoma (2.6%). Malignancy was most commonly located in distal esophagus (48 patients), and among the cases, 18 had involvement of the gastroesophageal junction. The most common benign cause was esophagitis secondary to reflux in 25.5% (56 patients), followed by esophageal ulcer in 5.9%, achalasia in 5%, corrosive stricture in 4.5%, and peptic stricture in 3.6%.

CONCLUSION

Dysphagia has diverse etiology, and a majority can be diagnosed by endoscopy and barium swallow. Malignancy is an important cause of dysphagia in elderly. Esophageal squamous cell carcinoma remains the most common malignancy, but the incidence of gastroesophageal junctional adenocarcinoma is increasing.
