利用张力－应力原理，采用球囊持续扩张方法，治疗肛门直肠狭窄患儿１３例，其中先天性肛门狭窄２例，肛门成形术后肛门狭窄５例，先天性直肠狭窄１例，术后或外伤性直肠狭窄４例，先天性肛门直肠狭窄１例。狭窄段长度０．６～１．０ｃｍ４例，１．２～５．０ｃｍ９例。８例曾经扩肛器扩肛失败。持续球囊扩肛每天２０小时，扩张压力在狭窄部静息压力曲线的迅速上升期范围。１３例中１２例成功，即排便通畅，肛检及球囊造影示狭窄段消失。所需时间５～１５天，平均６．７天。１例无效。随访６～１８个月无复发者。球囊持续扩张为治疗小儿肛门直肠狭窄的可靠方法，特别适用于狭窄段长和常规扩肛器扩张治疗失败的患儿。
Thirteen patients with anorectal stenosis were treated with continuous balloon dilatation by tension-stress principle, including 2 cases of congenital anal stenosis, 5 cases of anal stenosis after anoplasty, 1 case of congenital rectal stenosis, postoperative or traumatic injury 4 cases of rectum stenosis, 1 case of congenital anorectal stenosis. The narrow section length 0.6 ~ 1.0cm4 cases, 1.2 ~ 5.0cm9 cases. 8 cases had anal anal anal failure. Sustained balloon anal expansion 20 hours a day, the expansion pressure in the stenosis resting pressure curve of the rapid rise of the range. Of the 13 cases, 12 were successful, ie, defecation was unobstructed, anal examination and balloon angiography showed a narrow segment disappeared. The time required for 5 to 15 days, an average of 6.7 days. 1 case is invalid. Follow-up 6 to 18 months without recurrence. Continued expansion of the balloon for the treatment of children with anorectal stenosis reliable method, especially for the length of the narrow section and the expansion of conventional anus dilatation failure in children.
