多层螺旋CT对少见小肠梗阻的诊断价值

Diagnosis values of multislice spiral CT in rare small-bowel obstruction

目的评价多层螺旋CT(MSCT)对临床少见病因肠梗阻诊断的价值。方法回顾性分析18例经手术证实的少见病因肠梗阻的MSCT表现。结果 18例患者均有程度不等的肠梗阻。术前病因诊断正确率达72.22%,其中,先天性小肠壁神经节细胞减少1例,小肠阴性异物3例,小肠粪石2例,腹茧症1例,腹内疝2例,闭孔疝4例,小肠扭转5例。2例肠扭转并缺血坏死,3例并穿孔。结论 MSCT能用于少见小肠梗阻的病因及判断严重程度,还能够判断小肠梗阻后并发症的发生。

Objective To evaluate the value of multislice spiral CT （MSCT） in the diagnosis of rare small-bowel obstruction （SBO）. Methods The MSCT imaging features of 18 patients with rare cause of SBOs were retrospectively reviewed. Results The presence of SBOs was diagnosed in all patients on MSCT. The underlying etiology of SBOs were correctly diagnosed in 77.22% of patients. Among the 18 patients, congenital intestinal atresia were found in 1 case, foreign body in 3 cases, bezoar in 2 cases, abdominal cocoons in 1 cases, internal abdominal hernia in 2 cases, obturator hernia in 4 cases, small intestinal volvulus in 5 cases. Associated complications were arised in 5 patients with ischemia in 2 patients and perforations in 3 patients. Conclusion MSCT are not only useful for diagnosis and evaluation the severity of rare SBOs, but also useful for identifing the cause and associated complications of rare SBOs.
