How is postoperative dilation for congenital megacolon performed? Dilation is usually performed after two weeks of surgery. Dilation is performed with a dilation strip (or with a cervical dilation strip). Dilation is performed from the smallest size to the largest size, without skipping sizes. Apply sterile petroleum jelly to the front end of the dilation strip and insert it into the anus slowly, without violence. This should be done for the first time under medical supervision. Why is postoperative dilation necessary? Is it necessary for all children? The anastomosis of the anus is narrowed after surgery due to the contraction of the anastomotic scar. However, this varies from procedure to procedure and from child to child and should be determined on a case-by-case basis. How soon after congenital megacolon surgery should I start dilation? How long does dilation need to last? Dilation can be started three to four weeks after surgery. The duration of dilation depends on the individual case. How often should I dilate? What are the risks of frequent dilation? Dilation can be performed once a day. Dilation can still be painful for the child, so it is not advisable to do it more than once a day. When can I reduce the frequency of dilation? When can dilation be stopped? The frequency of dilation should be reduced or stopped as determined by the treating physician. Can I use cooking oil as a lubricant for postoperative dilation? Can I use my fingers instead of a dildo? Yes, it is best to lubricate with petroleum jelly. It is possible to use a finger instead of a finger, but it is better to use a dilation strip for dilation. What other precautions should I take when dilating? The dildo should be sterilized before use and applied to the front of the dildo with sterilized petroleum jelly and slowly inserted into the anus without violence. This should be done for the first time under medical supervision. In addition to dilation, what are the dietary concerns of the child? Some children with congenital megacolon are more prone to diarrhea than others, and each child reacts differently to different foods. Generally speaking, raw and cold foods tend to cause diarrhea in children. Therefore, it is necessary to pay attention to the diet and avoid some cold foods as much as possible.
