Discussion on imaging examination method and preoperative follow-up for gastric duplication in children

Abstract

Objective To report the clinical and imaging characteristics of 9 cases of gastric duplication in children, as well as to probe into all kinds of imaging examination methods, with an aim to improve preoperative diagnostic accuracy. Methods Nine cases of children with gastric duplication that received surgical resection and were pathologically confirmed in our hospital from January 2009 to November 2016 were retrospectively analyzed. The clinical manifestations, complications, complicated malformation and imaging findings of the cases were summarized. Three asymptomatic cases were carried out regular ultrasound examination follows-up preoperatively. Results Gastric duplication in children varied in terms of clinical manifestations. All the 9 cases were performed ultrasonography preoperatively, and 5 of them were accurately diagnosed. Meanwhile, 7 cases received preoperative CT examination, with 2 cases being confirmed. Three cases received magnetic resonance imaging (MRI) examination, with 2 cases being confirmed. And 2 cases had upper abdominal gastrointestinal imaging (GI) examination, but no definite diagnosis was made. Three cases of asymptomatic children with enlarged lesion can be seen in follow-up. Conclusions Gastric duplication is a rare congenital malformation, ultrasound allows to clearly display the capsule wall structure and the relation between gastric duplication with gastric wall, which is associated with high utilization rate and diagnosis rate, and it can be served as the preferred imaging examination method for gastric duplication in children.
