肥大性幽门狭窄是婴儿需要手术的最常见疾病。Fredt-Ramestedt式幽门肌切开术对于缓解症状效果极佳,而且死亡率异常低。但是,也有许多并发症,包括伤口感染或裂开、切口疝、十二指肠穿孔和出血。在成人幽门狭窄病例中,内窥镜气囊扩张疗法已试验成功,而儿童中的经验则非常有限。作者报道了3例采用此非手术疗法治疗的幽门狭窄患儿。在此以前,作者曾使用了专门的儿科胃肠内窥镜,并在19例患有食管狭窄的儿童中采用气囊扩张获得了经验。1988年,试验采用欧林巴斯(Olympus)
Hypertrophic pyloric stenosis is the most common condition in which babies need surgery. Fredt-Ramestedt pyloromyotomy is extremely effective in relieving symptoms and has an unusually low mortality rate. However, there are many complications, including wound infection or laceration, incisional hernia, duodenal perforation and bleeding. In adult cases of pyloric stenosis, endoscopic balloon dilatation has been successfully tested, and experience in children is very limited. The authors reported 3 cases of pyloric stenosis treated with this non-surgical therapy. Previously, the authors used specialized pediatric gastrointestinal endoscopy and gained experience with balloon dilatation in 19 children with esophageal stenosis. In 1988, the test used Olympus
