Why does constipation still occur after congenital megacolon surgery? There are various reasons for constipation after congenital megacolon surgery. Because of the different surgical methods, there may be different reasons, and the analysis of the common reasons for various surgical methods include: 1, the lesioned segment without ganglion cells or the migrated segment that needs to be removed for secondary lesions, which is not removed enough, and the lesioned segment at the anus and the end of the rectum is retained too much. 2, the normal intestinal tube without lesions in the anastomosis plane, if dragged to the anastomosis plane with too much tension, which makes the segment of intestinal tube ischemic, so that the anastomosis plane The intestinal tube above the anastomotic plane, ganglion cells are damaged and degenerated, and peristaltic function can be lost or weakened after surgery. 3, the anastomotic scar causes stenosis there. Does postoperative constipation require a second surgery? Is it effective to continue with enemas? If the symptoms of constipation and bloating do not improve after surgery or do not improve significantly, first you can go through non-surgical treatment, and if it still does not work, you can try to continue the enema first. After a period of time, the need for a new procedure will be evaluated. In some children, continuation of bowel lavage may result in the elimination of stool and reduction of abdominal distension. If there is no abdominal distension and the stool is not foul-smelling after the lavage, the lavage can be continued. After a period of time after the operation, the effectiveness of this method will be re-evaluated and the need for surgery will be decided. Why do some children have diarrhea after surgery? What should be done? After radical surgery for congenital megacolon, loose stools occur. Most of them are normal postoperative reactions, and most of them can pass a period of time with significant improvement of diarrhea symptoms. However, there are some children who have postoperative enteritis, and these children need to be cleansed again. This allows the inflammation in the intestinal wall to be reduced. If the diarrhea is significant, it can be examined and treated. How long does diarrhea persist before I need to be alerted to small bowel colitis? Does it require immediate medical attention? You need to be alert for small bowel colitis, which can occur right after surgery. This is related to whether the bowel was cleaned before the surgery. The need for immediate medical attention should be determined by the degree of diarrhea, whether the stool is foul-smelling, and whether it causes water loss and electrolyte disturbance. What causes postoperative diarrhea and blood in the stool? What is the treatment? Diarrhea with blood in the stool may be caused by frequent and loose bowel movements after surgery, combined with bleeding from the anastomosis. It may also be due to postoperative small bowel colitis. If the symptoms are severe, fasting and rehydration, additional antibiotics and metronidazole, and bowel cleansing may be added if necessary. Is it normal for postoperative bloating to be dilated and for the stool to be thin and acidic? It depends on the degree of bloating, how thin the stool is, and how sour it is. What is the problem of postoperative fecal incontinence and frequent staining of underwear with small amounts of stool? What should I do? Stained pants can occur after surgery, and if the degree is not severe, bowel training can be performed first. If the symptoms are severe, you should go to the hospital for consultation and treatment. Treatment and training should be carried out under the guidance of a doctor.
