Abstract
Congenital anorectal malformations are the most common congenital gastrointestinal malformations.The 3-stage surgery,composed of colostomy,anoplasty and colostomy closure,is generally performed for high anorectal malformations.The complete treatment course is about 6 to 12 months,however,along with many postoperative complications.To get a better outcome of surgery,the authors have carried out a new method.In the colostomy operation,we clean the intestinal contents with aspirator and sterilize the intestinal by 0.5％ povidone iodine solution.Under the guide of colonoscopy,a 20ml injector is punctured into the blind end of rectum and is inserted in a stainless steel wire.Then the other side of the wire is set in a stainless steel ball and a tie is made to fix tightly.Then we slowly pull out the stainless steel wire of the blind end of rectum and drag the ball to the bottom of the blind end of rectum.On the first day post operation,we start to pull the wire out gently,and then we do so everyday till the blind end of rectum is about 0.5cm close to the anus.Then the patient might undergo the anoplasty.Anal dilation is applied about 2 to 3 weeks after the anoplasty.The advantages of this method are as follows.Firstly,it can avoid the damages that laparotomy and laparoscopic may bring to the pelvic nerves,blood vessels,ureter and anal muscles,so that it can relieve pains of the patients.Secondly,the procedure is easy to learn and generalized,so it can be applied in grassroots hospitals.Thirdly,it apparently shortens the time of hospital stay and treatment course,so that it costs less,and the stainless steel ball will not get rusty or do harm to the intestinal.Lastly,the stool goes through the anus earlier,so that the anus muscles develop and recover better.关键词
