A circular membrane made of mucosa and submucosa is known as a Schatzki ring at the squamocolumnar junction of the distal esophagus. It resembles a delicate membranous structure without any muscularis propria. It always coexists with a hiatal hernia and has a lower surface covered in the columnar epithelium and an upper surface coated in squamous epithelium.
Small tissue folds that make up the Schatzki ring partially block the esophagus, causing dysphagia. In asymptomatic individuals, the Schatzki ring was originally discovered in 1944. It’s named after Richard Schatzki, a physician who made the initial observation. A Schatzki ring is one of the main reasons why adults experience difficulty swallowing solid foods and esophageal obstruction.
Epidemiology
6% to 14% of routine barium radiographs contain a Schatzki ring. It is known to be the most frequent factor in people with episodic dysphagia for solids and food impactions. There are no established population studies to estimate its prevalence in the general population.
Anatomy
Pathophysiology
The distal esophageal lumen becomes increasingly constricted as a Schatzki ring grows, which results in an intrinsic mechanical problem. As a result, when the diameter gets too small, food cannot pass through and symptoms of dysphagia or other difficulties, like food impaction, develop. Before the ring has a diameter that prevents food from passing, no symptoms are present.
The “Schatzki rule,” which was created by Richard Schatzki, states that a ring smaller than 13 mm will always be symptomatic while a ring greater than 25 mm will always be asymptomatic. Patients may have chest pain or odynophagia when food becomes lodged.
Etiology
A hiatal hernia is linked to Schatzki rings. The ring has been attributed to gastroesophageal reflux. The development of a Schatzki ring is thought to be the body’s natural defense against Barrett esophagus and a reaction to repeated acid exposure.
Studies have indicated that Barrett esophagus, particularly long-segment Barrett’s esophagus, is less frequent when a Schatzki ring is present. Schatzki rings and eosinophilic esophagitis have been linked.
Genetics
Prognostic Factors
When symptomatic, Schatzki rings are a benign stricture that can be successfully addressed. Frequently, the patient responds favorably to treatment, and their symptoms get better. Recurrence does happen, and rates in the first two years can reach 64%, necessitating further dilating.
