坏死性小肠结肠炎的X线表现(附141例报道)

The Radiology of Necrotizing Enterocolitis(NEC): a Report of 141 Cases

目的:总结坏死性小肠结肠炎的X线表现。方法:回顾性分析141例经临床证实的坏死性小肠结肠炎病例,怀疑或已诊断为坏死性小肠结肠炎者在首次腹平片后,根据病情每6～24小时复查腹平片,动态观察病情发展及转归。结果:小肠胀气扩张72例,部分肠管狭窄变细、形态僵直38例,局部胃肠道见"泡沫征"者12例,肠壁囊样积气者25例,肠壁线样积气者6例,肠壁囊样积气及线样积气者13例,门静脉积气者8例,气腹者21例。结论:坏死性小肠结肠炎的早期X线表现为肠管僵直、狭窄;进展期典型X线表现为肠壁积气及门静脉积气。X线检查为本病的首选检查方法。

Objective： To summarize the X-ray findings of necrotizing enterocolitis. Methods： 141 cases of necrotizing enterocolitis in the neonatal or infantal period who were diagnosed by clinical findings were reviewed. All these cases had abdominal plain film exam- inations on the first day in our hospital, and the follow-up films were taken at 6-24 hour intervals. Results： Distention of bowel was shown in 72 cases, stiffness of bowl was shown in 38 cases, pneumatosis was shown in 56 cases, portal venous gas was shown in 8 cases, and pneumoperitoneum was shown in 21 cases. Conclusion： Typical X-ray findings of NEC were stiffness and stenosis of bow, pneu- matosis and portal venous gas. Plain abdominal radiography is the first choice for the necrotizing enterocolitis.
