1974年,Gruntzig采用带囊导管治疗动脉狭窄性缺血获得成功,推动了经皮腔内血管成形术的开展。London等,于1981年首先将这种Gruntzig导管引用于胃肠道狭窄的治疗,对两例严重食管狭窄的病人成功地进行了扩张。此后,放射学家以及内窥镜学家广泛应用该方法治疗各种上胃肠道狭窄,获得满意效果。结肠狭窄扩张成功亦有病例报告。从1984年起,国内也开展了这项技术。 一、适应症和禁忌症 吻合口狭窄是上胃肠道手术后常见的并发症,发生率可达9％以上。这类病人再次手术困难较多;用带囊导管扩张法治疗则效果显著若,可做为首选方法。 由返流性或消化性食管炎形成的食道狭窄,幽门及十
In 1974, Gruntzig used a balloon catheter for the treatment of stenosis of the arteries to succeed, promoting the development of percutaneous transluminal angioplasty. London et al., First introduced this Gruntzig catheter in the treatment of gastrointestinal stenosis in 1981, successfully expanding two patients with severe esophageal stenosis. Since then, radiologists and endoscopists widely used this method to treat a variety of upper gastrointestinal stenosis and obtain satisfactory results. Successful cases of colon stenosis have also been reported. Since 1984, this technology has also been carried out in China. First, indications and contraindications anastomotic stenosis is a common complication after gastrointestinal surgery, the incidence of up to 9%. Such patients again surgery more difficult; with balloon catheter dilatation treatment is significant if the effect can be used as the preferred method.
