There are so many types of congenital megacolon, including total colon type, long segment type,, common type and short segment type. Depending on the length of the nerve cell defects, the clinical symptoms are different, and so are the treatment methods. Whole colon type megacolon treatment effect is very poor, relatively speaking, there is no good way, generally speaking, the early stage is needed to do fistula, do some special surgery, such as Martin surgery. If it is a long segment type, such as the entire sigmoid colon ganglion is missing, relatively long this kind of colonic abnormality, the operation is generally first to solve the fistula, so that the child can be able to normal nutritional development, can be not too lack of nutrients, the second stage when you can do the colonic anastomosis surgery. The short-segmented and common types can now be treated minimally invasively, such as laparoscopically, with simple resection of the abnormal bowel and reanastomosis. If it is short segmental type or localized dilatation of anal stenosis, sometimes after anal dilatation, long-term dilatation can be slowly relieved. Therefore, this kind of surgery is generally based on the severity of the disease, when the seriousness of the disease can be done first fistula, relatively mild can be a phase I surgery directly anastomosis.
