小儿急性肠系膜淋巴结炎的研究现状

Research Status of Acute Mesenteric Adenitis in Children

急性肠系膜淋巴结炎是小儿腹痛的常见原因,多见于7岁以下儿童。急性肠系膜淋巴结炎病因尚不清,临床表现以腹痛为主,腹部超声可发现肿大的淋巴结,可作为首选检查方法,但彩超的诊断标准存在争议。肠系膜淋巴结大在健康儿童中很常见,因此肠系膜淋巴结短轴直径超过8mm可提示肠系膜淋巴结炎。鉴别诊断包括急性阑尾炎、肠系膜淋巴结结核以及淋巴瘤。治疗主要针对病原抗炎及对症治疗。

Acute mesenteric lymphadenitis is a common cause of abdominal pain in children, usually seen in below 7 years of age. The etiology of acute mesenteric lymphadenitis is still unknown. Abdominal pain is the main clinical manifestation ,Enlarged mesenteric lymph nodes can be found by abdominal sonographic detection, and sonography should be the first choice of test. The diagnostic criteria of sonography is controver- sial. Since enlarged mesenteric lymph nodes are present in many healthy children, the lymph nodes with a short diameter larger than 8 mm may indicate the condition of mesenteric adenitis. Differentiated diagnoses include acute appendicitis, tuberculosis of mesenteric lymph nodes and malignant lymphoma. The main treat- ments are pathogen anti-inflammatory and symptomatic treatment.
