Abstract:
Objective To evaluate the value of high-frequency ultrasound and X-ray barium meal examination in diagnosis and typing diagnosis of congenital hypertrophic pyloric stenosis(CHPS).Methods High-frequency ultrasound and X-ray barium meal examination were made in newborns with present symptom of vomiting,and comparison was made between the two examine methods.Retrospective analysis was made in 29 cases confirmed by surgical operation.Control normal group included twenty healthy newborns.Results In 29 CHPS cases,the diagnostic accordance rate of ultrasound was 1 00%.And the diagnostic accordance rate of X-ray barium meal examination was 93.1%(27/29).In all those CHPS cases,the length of pyloric canal were≥18 mm,the diameter of pyloric canal were≥14 mm,the wall thickness of pyloric canal were≥4 mm,the stenosis inside diameter were≤6 mm by ultrasound;in X-ray barium meal examination,the length of pyloric canal were≥20 mm,the inside diameter were≥7 mm,and there was significant difference in comparison with control group(P＜0.01).The CHPS was classified into two groups as mild stenosis and severe stenosis according to the inside diameter and the wall thickness of pyloric canal.The mild type showed the wall thickness was＞4 mm and≤6 mm,the inside diameter was＞3 mm;The severe type showed the wall thickness was＞6 mm,the inside diameter was≤3 mm or obliterate.Conclusions High-frequency ultrasound has significant clinical application value in diagnosis and subtype diagnosis of CHPS,it is an easy,reliable and safe examination method.
