摘要
目的提高对儿童结肠重复畸形的X线和CT影像诊断水平。方法结合文献资料,分析经手术病理证实的11例儿童结肠重复畸形患儿的X线和CT表现、临床病理特点。结果 11例结肠重复畸形中,位于回盲部7例,升结肠3例,降结肠1例,均位于肠系膜侧,1例与降结肠相通呈管状型,10例与肠管不相通呈囊肿型。X线钡灌肠检查对管状型有确诊意义,主要表现为钡剂进入重复肠管内,呈分叉状,可见黏膜征。囊肿型CT主要表现为位于结肠内侧类圆形囊状低密度影,囊腔张力高,边缘清晰,部分囊壁呈分层状,内层密度稍低,外层稍高,见"晕轮征",增强后囊壁均匀强化,"晕轮征"显示更加清楚,和周围肠管强化时间及程度相似,连续多个层面形态变化不大,无分隔。结论结肠重复畸形是一种少见疾病,临床表现并无特异性,通过X线钡灌肠和CT增强检查,多能对结肠重复畸形作出明确的术前诊断。
Objective To improve the diagnostic accuracy of X-ray and CT in children colon duplication.Methods X-ray and CT features of 11 cases with colon duplication confirmed by pathology were retrospectively analyzed combine with literature data.Results Among 11 cases of colon duplication,7 cases located in the ileocecal junction,3 cases located in ascending colon,and 1 case located in descending colon,and all of the cases located in the mesenteric side.1 case connected with the descending colon and presented as tubular type,while 10 cases did not connect with intestine and presented as cyst type.X ray barium enema confirmed the tubular type,mainly for bowel barium to enter into a bifurcation like visible mucosa.The CT manifestation of cyst type was round cystic low density located inside of colon,sharp edge,part of the wall were layering,the inner density was lower,the outer slightly higher（＂halo sign＂）.The wall were uniform enhanced,＂halo sign＂ was seen more clearly,the time and extent of enhancement were similar to surrounding intestine,there were no morphological change and separation among continuous slices.Conclusion Colon duplication is a rare disease,which has no specific manifestation,preoperative diagnosis of colon duplication can be made with barium enema and enhanced CT.
