早期肠内营养在肠系膜上动脉综合征中的应用

The Role of Early Enteric Nutrition in Treatment of Superior Mesenteric Artery Syndrome

目的:探索早期肠内营养在肠系膜上动脉综合征(SMAS)治疗中的应用价值。方法:本院消化科2002年5月-2007年6月6例确诊的肠系膜上动脉综合征患者入院后进行内科保守治疗,症状缓解后行鼻空肠管置入术,连续5周肠内营养治疗。比较治疗前后患者呕吐、腹痛、体质量及肠系膜上动脉夹角角度的改变。结果:6例早期肠内营养治疗5周后:①5例(83%,5/6)治愈,1例(17%,1/6)好转;②体质量由(40±6)kg上升到(45±8)kg,P<0.05;③肠系膜上动脉夹角角度由(12±4)°增加为(45±7)°,P<0.05;④其中2例1年后复发。结论:早期肠内营养能减轻SMAS患者胃肠道症状,改善营养状况,增加体质量,扩大肠系膜上动脉夹角角度,可能是肠系膜上动脉综合征的一种有效治疗方法。

Objective： To explore the role of early enteric nutrition in the treatment of superior mesenterie artery syndrome （SMAS）. Methods： Between May 2002 and June 2007, 6 confirmed cases of superior mesenteric artery syndrome were included in this study. Early enteric nutrition was immediately initiated after resolution of symptoms. We compared the symptoms （vomiting or abdominal pain）, body weights and mesenteric artery angles in these patients before and after 5 weeks of enteric nutrition. Results： After 5 weeks of enteric nutrition, ① 5 patients （83%, 5/6） were cured, and 1 （17%, 1/6） showed significant improvement; ② there was an increase in body weights from （40±6） kg to （45±8） kg （P〈0.05）; ③ as well as an increase in mesenteric artery angle from （12±4）° to （45±7）° （P〈0.05）; ④ 2 cases recurred a year later. Conclusion： Early enteric nutrition was shown to benefit SMAS patients with relieved GI symptoms, improved nutrition, more weight gains and larger mesenteric artery angles, which appeared effective for treatment of SMAS.
