摘　　要：目的探讨锐器伤致肠管破裂的早期CT表现。方法实验用新西兰大耳白兔10只,在安静、未麻醉状态下行腹部CT扫描作为比对资料;麻醉后手术造成结肠肠管破裂实验模型,于术后2,4,8,12h行CT扫描,动态观察腹部CT表现。结果术后2h,破裂肠管轻度充血水肿;术后4h,破裂肠管管壁充血水肿较前明显,管壁增厚,腹腔少量积气;术后8h,肠管增厚、充血及扩张显著,腹腔积气、积液;12h,肠管管壁充血及肠管扩张范围扩大,腹腔积气、积液明显增多。结论兔试验结果提供了肠破裂的早期动态CT表现,为CT诊断早期肠破裂提供动物实验依据,提高临床早期诊断肠破裂的准确性。Objective To investigate the early stage multi-slice spiral CT（MSCT） image findings in the perforation of intestinal tract.Methods Ten New Zealand rabbits were performed abdomen MSCT scan at normal and un-anaesthesia situa-tion as control.After that experimental intestinal tract perforation was made and MSCT scan was performed at 2,4,8,and 12 hours post-surgery.Results Two hours after surgery,there was mild edema and injection in the locus of intestinal tract perfo-ration.After 4 hours,intestinal edema became more obvious with thickness increase of intestinal tract,and there was mild pneumoperitoneum.Eight hours post -surgery,there was remarkable edema and intestinal tract dilation with notable pneu-moperitoneum and peritoneal effusion.Twelve hours post-surgery,there was extension of intestinal injection and dilation,as well as prominent pneumoperitoneum and peritoneal effusion.Conclusion Experimental intestinal tract perforation provides time course MSCT image which may be helpful for clinic diagnosis of this disease in the early clinical stage.
