Scleroderma Esophageal Involvement
Overview
Plain-Language Overview
Scleroderma Esophageal Involvement is a condition where the esophagus, the tube that carries food from the mouth to the stomach, becomes affected by a disease called scleroderma. This disease causes the skin and connective tissues to become thick and stiff, and it can also affect internal organs like the esophagus. When the esophagus is involved, it can lead to problems with swallowing and cause heartburn or acid reflux. The muscles in the lower part of the esophagus may weaken, making it hard for food to move down properly. This can result in discomfort and difficulty eating. The condition mainly affects the digestive system and can impact nutrition and quality of life.
Clinical Definition
Scleroderma Esophageal Involvement is a manifestation of systemic sclerosis characterized by fibrosis and atrophy of the esophageal smooth muscle, primarily affecting the distal two-thirds of the esophagus. The underlying mechanism involves autoimmune-mediated vascular injury and excessive collagen deposition leading to esophageal dysmotility and lower esophageal sphincter (LES) incompetence. This results in impaired peristalsis and gastroesophageal reflux disease (GERD). Clinically, patients present with dysphagia, heartburn, and potential complications such as strictures or Barrett esophagus. The condition is significant due to its impact on nutritional status and risk of aspiration. It is commonly seen in patients with limited or diffuse cutaneous systemic sclerosis.
