How to identify oesophagus in tiffa scan?
Answers
Peristaltic waves in esophagus start from the upper position of the tube and pass into the complete length and impel the food into the stomach. This could be termed as Esophageal Peristalsis. The food particles left behind the esophagus begins with the secondary peristaltic waves that eliminate leftover particles. A single wave moves along the complete length of the tube. In cud-chewing animals like cattle, sheep, giraffes, and camels the reverse peristalsis happens such that the food is brought again to the mouth for chewing.
The peristaltic waves get disappeared after the stomach gets filled. The excess fats present in the food particles stop these movements until it gets diluted with gastric juices. These waves help in mixing the stomach content and drive the food into the small intestine. Normally, two to three waves exist at once in separate areas of the stomach.
Prenatal detection of esophageal atresia is poor, particularly in the presence of an associated tracheo-esophageal fistula. The sonographic “pouch sign” and “distended fetal hypopharynx”, as well as MRI and amniotic fluid analysis following a suspicious ultrasound, improve the detection rate.
