Abstract: Objective To investigate the clinical significance of ultrasonography in the diagnosis of duodenal obstruction in children. Methods The clinical data of 188 cases of duodenal obstruction confirmed by surgery in our hospital during Jan. 2011 and Dec. 2015 were retrospectively analyzed. The ultrasonographic results and surgical outcomes were compared to summarize the essentials of diagnosis. Results Before operation, all children had varying degrees of vomiting. Ultrasonographic images showed obvious dilation and effusion in the part between stomach and the proximal end of the obstructed intestinal cavity. In some cases, the bowel wall thickened. The distal end of obstructed intestinal cavity was poorly filled, or even empty. Ultrasonographic results indicated that 153 cases were duodenal obstruction, including duodenal atresia or stenosis, annular pancreas, and intestinal malrotation. The diagnostic accordance rate was 76.32%(29/38), 73.02%(46/63)and 89.66%(78/87), respectively. Some cases had 2 types of obstructions. Conclusion Ultrasonography plays an important role in the diagnosis of obstructive duodenal diseases and the location of obstructive site. It can serve as the first choice for screening duodenal obstruction in children.
