The results of balloon dilatation of upper digestive tract stricture in 111 patients were evaluated. Eighty-eight patients had esophageal strictures and 23 had gastric or pyloric strictures. Thirty-six patients had strictures associated with previous operations. Twenty-two percent of the patients with esophageal strictures had malignancies. Overall, 92% were successfully dilated, with a complication rate of 3%. Follow-up information was available in 95% of patients. Eighty-seven percent of living patients experienced symptomatic improvement, which lasted for a median period of 12 mo. Forty percent required a further procedure during the period of follow-up. We found no difference between esophageal strictures and gastric or pyloric strictures in success rate, complications, or need for further dilatation, although patients with esophageal strictures were more apt to have symptomatic improvement. Postoperative strictures responded as well as nonoperative strictures. Previously dilated strictures in patients with esophageal reflux were managed as successfully as strictures never before dilated. We found balloon dilatation of upper digestive tract stricture to be a safe, effective technique.
对111例上消化道狭窄患者的球囊扩张结果进行了评估。88例患者为食管狭窄，23例为胃或幽门狭窄。36例患者的狭窄与既往手术有关。食管狭窄患者中有22%患有恶性肿瘤。总体而言，92%的患者扩张成功，并发症发生率为3%。95%的患者有随访信息。87%的存活患者症状改善，症状改善持续的中位时间为12个月。40%的患者在随访期间需要进一步治疗。我们发现，食管狭窄与胃或幽门狭窄在成功率、并发症或进一步扩张需求方面没有差异，尽管食管狭窄患者更易出现症状改善。术后狭窄与非手术性狭窄的反应相同。食管反流患者既往扩张过的狭窄与从未扩张过的狭窄处理效果一样成功。我们发现上消化道狭窄的球囊扩张是一种安全、有效的技术。
