摘要
目的 探讨腹腔游离气的多排螺旋CT（MSCT）分布特点及其对胃肠道穿孔的定位诊断价值.方法 回顾性收集60例消化道穿孔病例,分析、观察CT图像中游离气的分布情况,以Treitz韧带为界,将消化道分为上消化道和下消化道,应用χ^2检验,分析其腹腔游离气分布的统计学差异,同时分析上、下消化道各不同穿孔部位之间腹腔游离气分布的统计学差异.结果 上消化道穿孔38例,下消化道穿孔22例,两组间腹腔游离气分布差异有统计学意义（χ^2=22.33,P〈0.001）,上消化道穿孔中,胃穿孔13例,十二指肠穿孔25例,两者之间腹腔游离气分布差异无统计学意义（χ^2=1.97,P〉0.05）,下消化道穿孔中,小肠穿孔11例,结肠穿孔11例,两者间游离气分布差异有统计学意义（χ^2=8.98,P〈0.05）.结论 MSCT腹腔游离气的分布特点对胃肠道穿孔定位有一定诊断价值.
Objective To study the distribution characteristics of intraperitoneal free gas and the location value of the site of gastrointestinal perforation using multi-slice CT （MSCT）.Methods 60 cases of gastrointestinal perforation were retrospectively collected.The distribution of the intraperitoneal free gas in CT image was analyzed and observed.The digestive tract were divided to the upper digestive tract and the lower digestive tract by Treitz ligament.The distribution of the intraperitoneal free gas was analyzed using χ^2 test.The distribution of the intraperitoneal free gas between each different perforational site was analyzed.Results 38 cases of the site of gastrointestinal perforation located in upper gastrointestinal tract and 22 cases located in lower gastrointestinal tract,there was statistically significant difference between the upper digestive tract and the lower digestive tract about the distribution of the intraperitoneal free gas（χ^2=22.33,P〈0.001）.In the cases of upper gastrointestinal tract perforation,13 cases of the site located in stomach and 25 cases located in doudenum,there was no statistically significant difference between stomach and duodenum（χ^2=1.97,P〉0.05）.In the cases of lower gastrointestinal tract perforation,11 cases of the site located in bowel and 11 cases located in colon,there was statistically significant difference between bowel and colon（χ^2=8.98,P〈0.05）.Conclusion The MSCT distribution of the intraperitoneal free gas has important value in localization diagnosis of gastrointestinal perforation.
