A stricture (stricture) in any part of the esophagus causes difficulty in descending into the stomach by staying in the esophagus (difficulty swallowing, dysphagia).
Difficulty in swallowing is not evident unless the esophagus diameter is less than 2 cm and may be difficult to notice by the patient.
While it is difficult to swallow solid foods in mild constrictions, as the severity of the narrowing increases, it becomes difficult to swallow liquid foods.
In the formation of severe stenosis, the patient is no longer able to eat or drink anything, and swallowed foods and saliva begin to come back into the mouth (regurgitation). There may be pain and/or a feeling of fullness behind the breastbone along with difficulty in swallowing. Patients often lose weight.
In stenosis of the esophagus due to organic diseases (cancer, caustic stenosis, stenosis after radiotherapy, etc.), swallowing difficulty is progressive and there is weight loss in a short time, while in functional strictures (achalasia, corkscrew esophagus, muscle diseases, etc.) it occurs intermittently and over the years. There is a slow progressing difficulty in swallowing and weight loss.
