We describe here 18 patients with gastrointestinal strictures through which a standard guide wire could not be passed, and which were dilated using a modified technique. After a 0.035" guide wire had been passed through a 5-Fr metal-tipped catheter, the narrow strictures were dilated using a 10-Fr biliary dilator. A modified Savary-Gilliard guide wire (olive-tipped with a hole) was passed over the 0.035" guide wire beyond the stricture. After removing the 0.035" guide wire, the strictures were dilated with Savary-Gilliard dilators passed over the olive-tipped guide wire. Seventeen patients had upper gastrointestinal strictures, and one had a sigmoid colon stricture. The strictures were caused by tumor in two, radiation therapy in six, esophagogastric resection for cancer in five, and a combination of two or more factors in five patients. The modified technique was successful in 17 patients, without any complications. Adequate symptomatic relief was achieved in 15 patients.
我们在此描述了18例胃肠道狭窄患者，这些狭窄处无法通过标准导丝，采用改良技术对其进行了扩张。在一根0.035英寸的导丝穿过一根5F金属头导管后，使用一根10F胆道扩张器对狭窄处进行扩张。一根改良的Savary-Gilliard导丝（带孔橄榄头）越过0.035英寸导丝穿过狭窄处。移除0.035英寸导丝后，通过越过橄榄头导丝的Savary-Gilliard扩张器对狭窄处进行扩张。17例患者为上消化道狭窄，1例为乙状结肠狭窄。狭窄的病因包括肿瘤2例、放射治疗6例、因癌症行食管胃切除术5例、两种或更多因素共同作用5例。改良技术在17例患者中取得成功，无任何并发症。15例患者症状得到充分缓解。
