高频超声介导下空气加压灌肠整复婴幼儿复发性肠套叠的临床研究

目的探讨高频超声介导下空气加压灌肠整复婴幼儿复发性肠套叠的临床价值。方法回顾性分析43例婴幼儿复发性肠套叠的临床诊治资料,总结可能引起婴幼儿复发性肠套叠的相关致病因素,鉴别特发性肠套叠与继发性肠套叠,分析高频超声介导下空气加压灌肠整复复发性肠套叠的优缺点。结果 43例复发性肠套叠患儿共复发96次,全部病例均在高频超声介导下经空气加压灌肠整复成功,整复成功后复查时发现4例存在病理诱发点,诊断为继发性肠套叠。43例复发性肠套叠患儿中,25例可探及肿大的肠系膜淋巴结。结论高频彩超介导下空气加压灌肠整复婴幼儿复发性肠套叠既能发现一些引起复发性肠套叠的病理诱发点等重要相关致病因素,又能使婴幼儿避免在传统的X线电视监视下短时间内多次遭受大剂量X线照射所造成的辐射伤害。

A Clinical Research of Air Enema Reduction of Infantile Recurrent Enteric Intussusception by High Frequency Ultrasound

Objective To explore the clinical merit of air enema reduction of infantile recurrent intussusception by high frenquency ultrasound. Methods The clinical diagnosis and treatment data of 43 cases of infantile recurrent intussusception were reviewed retrospectively. And the pathogenic factors related to infantile recurrent intussusception were summarized; a differentiation between idiopathic intussusception and secondary intussusception was conducted; the advantages and disadvantages of air enema reduction of recurrent intussusception by high frenquency ultrasound were analyzed. Results 43 cases of infantile recurrent intussusception recurred 96 times, and the air enema reduction of all the cases of infantile recurrent intussusception by high frequency ultrasound was successful. Pathologic lead point was found in 4 cases during the return visit and the patients were diagnosed with secondary intussusception; and tumescent mesenteric lymph nodes were found in 25 cases. Conclusion Air enema reduction of infantile recurrent intussusception by high frequency ultrasound can not only find pathologic lead points and other important related pathogenic factors of infantile recurrent intussusception, but also make the infant avoid the radiation damage caused by repeatedly high dose X-ray irradiation in a short period of time under the traditional X-ray fluoroscopy.
