摘要
目的探讨X线腹部平片和CT检查在肠梗阻诊断中的价值。方法搜集近年来51例肠梗阻病例,其中46例经手术治疗,平均年龄51.6岁,对X线腹部平片及CT影像学表现进行比较:分析梗阻是否存在、梗阻部位、病因的推断、梗阻程度的判断及有无绞窄性梗阻。结果46例经手术证实病例中,机械性梗阻45例(含绞窄性梗阻12例),误诊3例。其中小肠梗阻23例,结肠梗阻21例,2例伴有肠穿孔。结论X线腹部平片与CT是诊断肠梗阻的有效方法,CT检查对梗阻病因、部位、类型的判断有其明显优势,尤其是绞窄性梗阻时肠系膜的变化有其较明显特征,是减少误诊的必要手段。
Objective To evaluate the value of plain film and CT scan in the diagnosis of intestinal obstruction. Methods Collected 51 cases of intestinal obstruction in recent years.46 cases by operation corroborative.The average age is 51.6 years. 51 cases were analysed and compared with the disease imaging reflect of plain film and CT ： display of signs of obstruction, position, factor, degree , strangulation were judged. Results 46 cases by operative proved, mechanical obstruction in 45 cases （included strangulation in 12 cases ）, misdiagnosis in 3 cases, small bowel obstruction in 22cases, obstruction of colon in 24 cases , with intestinal perforation in 2 cases . Conclusion It is effective methods of application with plain film and CT scan in diagnosis of intestinal obstruction. CT examination has its obvious advantages to judgement cause, position, type of intestinal obstruction,especially. It is characteristic of the mesenteric changing in strangulation obstruction, so it is a necessary method to decrease the misdiagnosis.
