目的:对比分析3种手术方式在治疗小肠闭锁中的疗效，为小肠闭锁患儿个体化手术治疗提供依据。方法:回顾性分析福建省妇幼保健院2008年1月至2017年9月168例小肠Ⅱ、Ⅲ、Ⅳ型闭锁患儿临床诊治资料，按术式不同分为3组：端端吻合组（58例）、端斜吻合组（68例）、近端裁剪端端吻合组（42例），端端吻合组和端斜吻合组又分为近端肠管口径>远端4倍a组，≤远端肠管口径4倍的b组。对比分析各组患儿性别、胎龄、出生体重、肠闭锁类型及术后排便时间、术后进食时间、术后住院时间及术后随访半年并发症情况。结果:各组患儿性别、胎龄、出生体重、肠闭锁类型对比差异无统计学意义（n P>0.05），近端裁剪端端吻合组在术后排便时间、术后进食时间、术后住院时间及并发症情况均优于端端吻合a组和端斜吻合a组（n P0.05). The PEA group was better than EEA-a group and EOA-a group in postoperative defecation time, postoperative feeding time, postoperative hospital stay and complications (n P<0.05). The postoperative defecation time, postoperative feeding time, postoperative hospital stay and complications of the EOA-a group were better than those of the EEA-a group (n P0.05), but the postoperative hospital stay in the EEA-b group was longer than that in the EOA-b group (n P<0.05).n Conclusion:PEA is recommended for children with a proximal intestinal canal diameter greater than 4.0 times greater than the distal end because of the rapid recovery and fewer complications; EOA is recommended for children with a proximal intestinal canal diameter of 4.0 or less because of its advantage of shorter hospital stay than EEA surgery. Congenital intestinal atresia has a better effect according to the specific conditions of the child.
