目的：观察先天性直肠狭窄的康复效果。方法： 对１２ 例先天性直肠狭窄的患儿， 在骶管麻醉下，采用单纯扩张法，即用扩肛器、手指进行扩张。对高位狭窄者， 进行手术， 分别经后矢状入路狭窄处纵切横缝或环状切除狭窄部端端吻合， 术后狭窄处乾地３～６ 个月的扩张。结果：患者均治愈。单纯扩张者，有２ 例经常便秘，经对症治疗好转。结论：经观察证明，直肠狭窄处直径在０．３ ｃｍ 以上者皆可进行狭窄处扩张，循序渐进，防止肠穿孔。直径小于０．３ ｃｍ，或扩张失败者，可考虑手术治疗 Objective: To observe the effect of congenital rectal stenosis. Methods: Twelve cases of congenital rectal stenosis in children, caudal anesthesia, the use of simple expansion method, that is, with anal augmentation, finger expansion. For high stenosis, surgery, respectively, after the sagittal approach longitudinal suture transverse or annular resection stenosis end anastomosis, postoperative stenosis dry 3-6 months of expansion. Results: All patients were cured. Simple expansion, there are 2 cases of constipation, symptomatic treatment improved. Conclusion: The observation shows that the diameter of rectum stenosis at 0.3 cm or more can be expanded at the stenosis, step by step, to prevent intestinal perforation. Diameter less than 0.3 cm, or expansion failed, consider surgery
