21例强制戒毒人员吞服异物后影像学检查资料回顾性分析

Retrospective Analysis of 21 Cases with the Imaging Data of Foreign Objects Swallowed by Drug Addicts under Compulsory Rehabilitation

目的探讨常规X线与CT检查对吞服异物者体内异物鉴定的价值。方法回顾性分析21例吞服异物者的影像资料,使用CT、常规X线检查比较法得出体内异物损伤的程度。结果本组实验使用常规X线检查的间接征象推断其穿孔检出率为14.29%(3/21),而CT诊断穿孔准确率为85.71%(18/21),并能精确显示异物大小、材质与穿孔部位以及周围组织器官的情况。结论 CT检查应成为消化道异物损伤鉴定、风险评估、指导治疗的常规检查。

Objective To discuss the value of conventional X-ray and CT examination in verifying foreign objects swallowed by the drug addicts under compulsory rehabilitation. Methods Retrospective analysis was made upon the conventional X-ray and CT image data obtained from 21 cases of foreign objects swallowed by drug addicts who were under compulsory rehabilitation. Their degree of injury was appraised and compared according to the observations with the conventional X-ray and CT test. Results Conventional X-ray detection revealed the perforation incidence of 14.29% （3/21） through the shown indirect signs, but the CT approach was 85.71% （18/21） and accurately displayed the sizes of foreign objects, their materials, the puncturing sites and the surrounding tissues plus organs. Conclusion CT examination should be defined as a routine measure for the gastrointestinal observation to identify injury, assess risk and guide therapy in involving with the drug addicts who swallowed foreign objects.
