摘要
目的 探讨超声显像对胃窦癌的诊断价值。方法 应用B型超声空腹观测31例胃窦癌的声像图表现,观察病灶侵犯部位、层次累及邻近器官情况,周围脏器有无转移等,并与X线上消化道双重对比造影、纤维胃镜检查作对比,最后与手术病理诊断结果进行对照。结果 31例胃窦癌超声诊断与手术病理诊断的符合率为87.09％(27/31),X线检查诊断符合率为89.47％(17/19),胃镜检查的诊断符合率为90.04％(19/21),三者比较经统计学处理无显著性差异(P>0.05)。31例胃窦癌依癌肿侵犯范围分为局灶型和弥漫型。本组局灶型占12.9％(4/31),多为早期癌肿。弥漫型占87.10％(27/31),多为中晚期癌肿。局灶型包括凹陷型和局限隆起型,仅累及粘膜肌层和下层。弥漫型包括向心浸润型和偏心浸润型,向心型系环状浸润和腔内恒定对称狭窄,偏心型系不规则浸润。声像图上纵切呈“鸭嘴征”,横切是“假肾征”或“类靶环征”。结论 超声显像诊断胃窦癌局限于中晚期,对早期或小胃癌的诊断尚有待于进一步研究。
Purpose To evaluate the diagnostic value of antral carcinoma of stomach with ultrasonogram; Methods Thirth-one cases of the antral carcinomas were observed with B-mode ultrasonography, all these patients were fasted. Invasive regions and layers, involved adjacent organs and metastatic lymph nodes of the carcinoma were observed, these findings were compared to X-ray findings of the stomach and fiberscopes for the gastroduodenum,and finally compared to the postoperated pathological results. Results The ultrasonogram diagnosis coincidence rates of 31 cases of the antral carcinoma were compared with postoperated pathological results X-ray and fiberscopes findings were 87.09%(27/31) ;89.47%(17719); and 90.04% (19/21) . And these are no significant results were found (p > 0.05). In these 31 cases of the antral carcinoma, the invasive regions and layers were classified into confined carcinoma and diffused carcinoma. The confined ones were 12.9 % (4/31), most of them were early stage; the diffused ones 87.10% (27/31), most of them were middle serious and late stage. The confined ones included depressed type and protrusive type, penetrated mucosal layer, submucosal muscle layer,and proprietary muscle. The diffused ones included a centripetal penetrated mass and an eccentric penetrated mass. The symmetry mass was invaded circularly and centripetal stenosis in the lumen. The eccentric mass invaded irregularly. The ultrasonogram manifested 'duck mouth' syndrome in longitudinal section; and 'false kidney' or 'target cycle' syndrome in transversal section. Conclusions The diagnosis of the antral carcinoma in the ultrasonogram only limited to the serious and late cancer, and for the diagnosis of the early stage or small gastric cancer still needed to further study.
