螺旋CT诊断Bouveret综合征的临床价值

Clinical Value of Spiral CT in Diagnosing of Bouveret Syndrome

目的:分析Bouveret综合征的CT征象,探讨螺旋CT诊断Bouveret综合征的临床价值。方法:回顾分析6例经手术和病理证实的Bouveret综合征的临床资料及CT影像学特征。结果:6例螺旋CT平扫均见肠腔内异位结石及胆道、胆囊积气,6例结石上方均出现不全性梗阻。结石位于十二指肠降部4例,十二指肠球部1例,空肠近段1例;高密度结石4例,等密度结石1例,低密度结石1例。6例术前螺旋CT平扫均诊断为Bouveret综合征,诊断准确率100%。结论:螺旋CT对Bouveret综合征能明确诊断,可以作为急诊的首选检查方法。

Objective： To analyze the CT signs of Bouveret syndrome and to explore the clinical value of spiral CT in diagnosing of Bouveret syndrome. Methods： The clinical datas and CT signs of 6 patients with Bouveret syndrome comfirmed by surgery and pathology were analyzed retrospectively. Results： In 6 cases, the spiral CT scan images showed that ectopic stones were found within the intestine, gases was found within bile duct and gallbladder, and incomplete obstruction was found in intestine above the stones. The numbers of the stones wedged in the descending duodenum is 4, in the duodenal is 1, and in the proximal of jejunum is 1. Meanwhile, we found that high-density stones in 4 cases, isodense stones and low-density stones in 1 case respectively. The diagnostic accuracy rate of spiral CT scan preoperatively to Bouveret syndrome was 100%. Conclusion： Spiral CT scan can contribute to confirm the diagnosis of Bouveret syndrome and can be used as the preferred method in emergency.
