摘要粘连性肠梗阻是肠梗阻中最常见类型，通常以保守治疗为首选治疗方案。保守治疗过程中，胃肠减压能够缓解症状，防止肠梗阻进展，加速胃肠道功能恢复，具有显著临床效果。目前关于鼻肠管和鼻胃管对粘连性肠梗阻的减压效果尚存争议。既往有Meta分析对两者的临床效果作出评价，但是纳入研究包括非随机对照研究，且缺少关于中国患者的相关研究。因此，笔者采用Meta分析评价鼻肠管和鼻胃管对粘连性肠梗阻减压效果。

abstractsAdhesive intestinal obstruction is the most common type of ileus, and conserva-tive treatment serves as its preferred treatment option. In the course of conservative treatment, gastrointestinal decompression will relieve symptoms, prevent ileus progression and promote gas-trointestinal function recovery, which has significant clinical effects. Currently, decompression effects of nasointestinal tubes and nasogastric tubes are controversial. There is a previous Meta-analysis evaluating decompression effects of these two methods, but this analysis includes non-randomized controlled trial and lacks research about Chinese patients. Therefore, the authors con-duct a Meta-analysis to evaluate decompression effects of nasointestinal tubes versus nasogastric tubes for adhesive intestinal obstruction.
