What is lower esophageal ring?
A lower esophageal ring, also known as Schatzki ring, is a thin band of tissue that can narrow the lower part of the esophagus, leading to difficulty swallowing. It can be associated with gastroesophageal reflux disease (GERD) and can be diagnosed through an endoscopy. Treatment may involve stretching the ring or managing underlying GERD.
How is lower esophageal ring corrected?
Lower esophageal rings can be corrected by passing a bougie (a cylindrical, mercury-filled dilator) through the esophagus. This procedure, called bougienage, is effective most of the time, but may need to be repeated every few years.
