摘要
目的探讨CT对肠腔内异物所致机械性小肠梗阻诊断的价值。方法回顾性分析8例经手术证实的肠腔内异物所致机械性小肠梗阻的CT表现。结果 8例患者均有程度不等的肠梗阻,7例术前均正确的做出肠梗阻诊断,其中小肠食入性异物小肠梗阻3例,粪石性小肠梗阻2例,胆石性小肠梗阻2例。另1例粪石性小肠梗阻术前诊断为小肠肿瘤。所有患者均无肠缺血坏死、穿孔等并发症。结论通过典型的征象分析,CT能术前诊断肠腔内异物所致机械性小肠梗阻。
Objective To evaluate the value of CT in diagnosis of rare mechanical smallbowel obstruction （SBO） caused by intraluminal foreign bodies. Methods The CT imaging features of 8 patients with mechanical SBOs caused by intraluminal foreign bodies were reviewed retrospectively. Results The presence of mechanical SBOs in 7 cases were diagnosed by CT imaging beforeoperation, including the ingested foreign bodies in 3 cases, bezoars in 2 cases and gallstones in 2 cases. Another one was misdiagnosed the bezoars as tumor. All cases were confirmed by open abdomen operation. SBO-related complications such as ischemia and perforation were not found in all patients. Conclusion CT examination are effective for diagnosis of mechanical small-bowel obstruction （SBO） caused hy intraluminal foreign bodies by the typical CT signs.
