消化道来源腹腔异物的MSCT表现及临床分析

目的探讨消化道来源腹腔异物的多排螺旋CT(MSCT)表现及价值,分析归纳其可能发生的原因。方法回顾性收集2017年1月至2019年7月在本院检查或收治的腹腔内游离异物11例,所有患者均有腹部X线平片及MSCT检查资料,并最终手术证实;有两位主治以上年资影像医师分析MSCT表现,观察腹腔异物类型、游离部位及其并发症发生情况。结果11例患者均为服刑人员,男9例,女2例;年龄22~51岁,平均(36.5±14.5)岁。MSCT发现异物位于肝脏2例,肝胃间隙2例,胰腺1例,胰周1例,小肠系膜内2例,膀胱直肠陷凹3例,异物形态均为金属针样。结论相对于常规平片,MSCT可明确诊断腹腔内游离异物的位置、形态、材质及其并发症情况,可为临床随访或进一步治疗提供准确而直观的参考。

Objective To explore the manifestation and value of multi-slice spiral computed tomography(MSCT)of abdominal foreign bodies from digestive tract,and to analyze and summarize the possible causes.Methods 11 cases of intra-abdominal free foreign bodies were retrospectively collected in the study,and were examined or treated in our hospital from January 2017 to July 2019.All patients were performed abdominal X-ray plain film and MSCT examination,which were confirmed by surgery.MSCT images were analyzed by two senior radiologists,observing the types of intraabdominal foreign bodies,locations and the occurrence of complications.Results All the 11 patients were criminals,9 were male and 2 were female,aged 22-51 years,with an average age of(36.5±14.5)years.MSCT showed that the foreign bodies were located in the liver in 2 cases,the space between liver and stomach in 2 cases,pancreas in 1 case,peripancreatic in 1 case,mesentery in 2 cases,vesicorectal depression in 3 cases.The foreign bodies were all metallic needles.Conclusion Compared with conventional X-ray plain film,MSCT can clearly diagnose the location,shape,material and complications of intraperitoneal free foreign bodies,and provide accurate and intuitive reference for clinical follow-up or further treatment.
