摘要
目的:探讨老年性食管裂孔疝并疝囊内结石的X线诊断要点及其形成机制。方法:回顾性研究7例老年性食管裂孔疝合并结石的气钡双重造影X线表现特点。结果:由于老年性疝囊两端的A环、C环在长期慢性炎症的刺激下纤维化而狭窄,使疝囊膨胀表现为"吹气球征",7例疝囊上下两端狭窄。7例疝囊内结石未服用产气粉前表现为与疝囊同等大小且边缘光滑的充盈缺损,充盈缺损的长轴与食道长轴方向基本一致,呈现"食管疝囊铸型征"。钡剂沿着充盈缺损的疝囊周壁进入膈下胃腔,多方位旋转显示疝囊轮廓边缘十分光滑且完整,其内充盈缺损与疝囊壁之间存在薄而完整的钡线影。3例充盈缺损的上缘表现为"尖顶征",4例"圆顶征"。服用产气粉后,表现为结石与疝囊形成"套圈征"。结论:老年性食管裂孔疝并疝囊内结石在X线表现上有其特有的征象,能够做出准确诊断。
Objective：To investigate the X-ray diagnostic highlight and form mechanism of lithiasis in the elder hiatal hernia sac. Methods： Study the features of X-ray findings of 7 cases about lithiasis in the elder hiatal hernia sac with double contrast barium meal. Results：Both sides of elder hernia sac became constrictive because of fibrosis caused by A ring, C ring chronic inflammation, which made hiatal hernia sac dilate like a expanded balloon, 7 cases were manifested stenotie at the two ends. Lithiasis in the hiatal hernia sac display of filling defect the same as the smoothly sac without aerogenic powder. Long axis of filling defect were accorded with that of esophagous, the sign could he described as ＂cast mould＂ of esophagous hiatal hernia sac. Barium agent enter the hypophragmatie gastral cavity circumferencely, multi-directions showed the verge of esophagous hiatal hernia sac were smooth and intact extremely. There were imaging of fine line between the filling defect and the wall of hiatal hernia sac. The superior border of filling defect could he described as ＂pointed top＂ in 3 cases, while ＂round top＂ in 4 cases. The lithiasis and hiatal hernia sac formed the sign of ＂double loop＂ after taken aerogenic powder. Conclusion：X-ray findings of lithiasis in the elserly hiatal hemia sac had some special signs, which could he diagnosed accurately.
