Gastric surface mucosal cells are responsible for the uptake and secretion of 99mTcO4, a feature that has been used in imaging heterotopic gastric mucosa. We used the same principle to look for gastric mucosal viability in this case of pure esophageal atresia admitted for cervical stomal closure after a previous isoperistaltic gastric tube (IGT) replacement procedure. 99mTcO4 scintigraphy was done after encountering a failure to maneuver the esophagoscope through the IGT. The study was helpful in assessing the loss of gastric mucosal viability in an intervening segment of the IGT.

D004933 Esophageal Atresia Congenital abnormality characterized by the lack of full development of the ESOPHAGUS that commonly occurs with TRACHEOESOPHAGEAL FISTULA. Symptoms include excessive SALIVATION; GAGGING; CYANOSIS; and DYSPNEA. Atresia, Esophageal,Atresias, Esophageal,Esophageal Atresias
D004944 Esophagoplasty A plastic operation on the esophagus. (Dorland, 28th ed) Esophagoplasties
D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
