Balloon dilation is a useful alternative to surgery in patients with benign pyloric stenoses. However, little data are available on the long-term outcome of the procedure.
Fourteen patients with benign pyloric stenoses were treated by through-the-scope balloon dilation. Short-term and long-term follow-up was conducted (median 27 months).
Balloon dilation was successfully performed in 12 patients (86%), and all 12 had immediate relief of symptoms after a single session. During a median follow-up of 27 months, 50% of the patients had recurrences of their symptoms, requiring redilation. Following this, two patients became symptomatic once again; one underwent surgery, and the other received a further session of balloon dilation, and was well at a further follow-up after one year.
Balloon dilation of benign pyloric stenoses results in short-term symptomatic relief in the majority of patients. However, in the long-run, about half of the patients can be expected to experience a recurrence of symptoms, requiring further endoscopic or surgical treatment.
对于患有良性幽门狭窄的患者，球囊扩张术是一种有效的手术替代方法。然而，关于该手术长期疗效的数据却很少。
14例患有良性幽门狭窄的患者接受了经内镜球囊扩张术治疗。进行了短期和长期随访（中位时间27个月）。
12例患者（86%）成功进行了球囊扩张，所有12例患者在单次治疗后症状立即缓解。在中位随访27个月期间，50%的患者症状复发，需要再次扩张。在此之后，2例患者再次出现症状；1例接受了手术，另1例接受了进一步的球囊扩张治疗，1年后的进一步随访时情况良好。
良性幽门狭窄的球囊扩张术可使大多数患者短期内症状缓解。然而，从长远来看，预计约一半的患者会出现症状复发，需要进一步的内镜或手术治疗。
