Ectopic Gastric Mucosa

Kumar et al. (2005) described a series of 11 (male) children in which the diagnosis of ectopic gastric mucosa could be made by the use of 99Tcm-

\c pertechnetate scintigraphy. Functioning ectopic gastric mucosa was found in Meckel diverticulum in three patients, in small bowel duplications in four, in a gastric duplication in one and in intrathoracic foregut duplication cysts in three patients. They stress the importance of performing a dynamic and static sequence as well as delayed images (up to 24 h) since only the latter can document the presence of ectopic gastric mucosa in patients with intrathoracic duplication cysts; this is much later than the visualization of the stomach activity. In contrast, the tracer activity in ectopic gastric mucosa in intestinal duplication cysts may be seen before gastric tracer activity. The uptake of 99Tcm-pertechnetate in the ectopic gastric mucosa of Meckel diverticulum and gastric duplication is visualized simultaneously with the stomach (Fig. 3.7).

Meckel diverticulum is the most common congenital anomaly of the GI tract and is the most common site for ectopic gastric mucosa. GI duplications (non-communicating or more rarely communicating) are less common and 20%-30% of these will contain ectopic gastric mucosa. It is also more commonly seen in tubular duplications (in contrast to cystic).

Patients with functioning ectopic gastric mucosa will present with pain, bleeding and perforation. However, patients with intrathoracic foregut duplication cysts, mainly younger patients, will present with respiratory distress caused by compression of the airway.
