目的探讨新生儿环状胰腺的高频超声表现及超声对环状胰腺的诊断价值。方法回顾性分析11例经手术确诊的新生儿环状胰腺的超声图像及临床资料,观察梗阻部位、胰头形态、十二指肠与胰头关系,总结其超声表现。结果 11例新生儿环状胰腺超声均表现为:胰头呈“钳夹”状半环绕十二指肠降部;胰头与十二指肠肠壁分界不清;十二指肠局部受压、管腔突然变细;梗阻近段扩张,远段肠腔充盈差。结论当超声发现有十二指肠梗阻后,胰头呈钳夹状改变且胰头与十二指肠分界不清时,应高度怀疑环状胰腺的可能。
Objective To investigate the performance of neonatal annular pancreas by high-frequency ultrasonography and its diagnostic value in annular pancreas. Methods A retrospective analysis of 11 cases of surgically diagnosed neonatal annular pancreas by ultrasound images and clinical data were observed obstruction site, pancreatic head morphology, duodenum and pancreatic head, summarize the ultrasound findings. Results 11 cases of neonatal annular pancreas showed as follows: the head of the pancreas was “clamp-like” half around the descending part of the duodenum; pancreatic head and duodenal intestinal wall is unclear; duodenal local Pressure, lumen suddenly thinning; proximal obstruction expansion, poor filling of the distal intestine. Conclusions When the duodenal obstruction is found by ultrasound, the head of pancreas changes in the shape of a clip, and the border between pancreas and duodenum is unclear, the possibility of annular pancreas should be highly suspected.
