儿童食管化学性灼伤致疤痕狭窄的介入治疗

Interventional therapy of postburn oesophageal cicatricial stricture in childhood

目的探讨儿童食管化学性灼伤致疤痕狭窄的介入球囊扩张治疗的疗效。方法8例化学性灼伤致食管疤痕患儿在出现临床症状如咽下困难、反流,及呕吐后1～3月内接受了球囊扩张治疗。全部患儿经随访6个月～2年。结果8例患儿经球囊扩张治疗4～12次,其中7例临床症状明显改善,基本上能进普食,随访6个月～2年无狭窄症状;1例碱性物质灼伤共经12次扩张治疗效果不佳,行外科手术治疗。结论球囊扩张术治疗儿童食管化学性灼伤致疤痕狭窄是一种安全可靠有效的治疗方法。但食管狭窄严重经多次球囊扩张术无效者,需手术治疗。

Objective To determine the efficacy of balloon dilatation in children with oesophageal cicatricial stricture(OCS)induced by chemical burns.Methods Eight children with OCS underwent th e treatment of balloon dilatation wi thin 1to 3months after onset of clini cal symptoms such as dysphagia,regurgitation and emesis,and then they also received the follow -up for 6months t o 2years.Results Fol-lowing balloon dilation for 4～12tim es,7of 8cases reponded well to treatment,with significant relief of cli nical symptoms and basically enable to the general foodstuffs wit hout reccurrence of dysphagia durin g followed -up for 6months to 2years.Only one patient with alkali burn,who failed to carry out balloon dilation for 12times eventually rec eived surgical therapy.Conclusion Balloon dilation is a safe,reliable,and effective procedure i n the treatment of postburn OCS in chi ldren but highly severe OCS that is unable to cure after many times of balloon dilation needs the operation.[
