Hydrostatic balloon dilation is being increasingly used for gastrointestinal stenoses, but few data are available regarding efficacy or side effects. A survey sent to 3000 A/S/G/E members showed that 22% of responding endoscopists used the balloon method. Data available on 1538 patients revealed an overall technical success rate for balloon dilation of 85%. Immediate symptomatic relief of obstructive symptoms was 85% for the esophagus, 76% for the stomach, 56% for the colon, 89% for the bile duct, and 67% for the pancreatic duct. Objective improvement at 3 months fell, respectively to 39%, 38%, 72%, 60%, and 62%. Six percent of total procedures were associated with complications, and these complications could not definitely be correlated with balloon size. Although the present survey defines current usage patterns, prospective studies over a long follow-up period are needed to define the place that hydrostatic balloons should play in the treatment of gastrointestinal stenoses.
水囊扩张术越来越多地用于治疗胃肠道狭窄，但关于其疗效或副作用的数据却很少。一项针对3000名美国胃肠病学会（A/S/G/E）成员的调查显示，22%的内镜医师使用了气囊扩张法。1538例患者的现有数据显示，气囊扩张术的总体技术成功率为85%。梗阻症状的即时症状缓解率在食管为85%，胃为76%，结肠为56%，胆管为89%，胰管为67%。3个月时的客观改善率分别降至39%、38%、72%、60%和62%。6%的手术与并发症相关，且这些并发症与气囊大小无明确关联。尽管本次调查明确了当前的使用模式，但仍需要进行长期随访的前瞻性研究，以确定水囊扩张术在胃肠道狭窄治疗中应发挥的作用。
