Radiologically guided balloon catheters were used to dilate 94 gastrointestinal strictures in 92 patients over a 6-year period. Fifty strictures were esophageal and 44 nonesophageal (22 gastroenterostomies, 11 antral-pyloric strictures, four colorectal strictures, four enteroenterostomies, and three miscellaneous strictures). Factors influencing the success of stricture intubation included patient age, stricture location (esophageal vs. nonesophageal and proximal vs. distal esophageal), and association with a surgical anastomosis. Malignancy was associated with greater postdilation irregularity and a smaller increase in stricture diameter, as measured radiographically. Procedural failures occurred in 8% of cases (2% of esophageal and 30% of nonesophageal lesions). Two small, asymptomatic mucosal tears were seen after dilation (one esophageal and one colonic); no other procedural complications occurred. Following successful dilation, 16 patients (17%; six with esophageal and ten with non-esophageal strictures) had recurrence of symptoms during short-term (30-day) follow-up.
在6年时间里，采用放射引导的球囊导管对92例患者的94处胃肠道狭窄进行了扩张。其中50处狭窄位于食管，44处位于非食管部位（22处胃肠吻合口狭窄、11处胃窦-幽门狭窄、4处结肠狭窄、4处肠肠吻合口狭窄以及3处其他类型狭窄）。影响狭窄插管成功的因素包括患者年龄、狭窄部位（食管与非食管，以及食管近端与远端）以及是否与手术吻合口相关。影像学检查显示，恶性病变与扩张后更严重的不规则性以及狭窄直径较小的增加相关。8%的病例出现操作失败（食管病变为2%，非食管病变为30%）。扩张后可见2处小的无症状黏膜撕裂（1处食管，1处结肠）；未发生其他操作并发症。成功扩张后，16例患者（17%；6例食管狭窄患者和10例非食管狭窄患者）在短期（30天）随访期间出现症状复发。
