After megacolon surgery, most patients can recover like normal people. Some patients may have constipation, abdominal distension and dirty stools after the surgery, which can be relieved effectively in most cases, but some patients cannot. After megacolon surgery, most patients can return to normal, but if the spastic, narrowed intestines are not completely removed, it may lead to megacolon recurrence; some patients may experience constipation, abdominal distension, dirty stools and other symptoms after surgery, most of which can be effectively relieved after bowel training, but some patients cannot. Megacolon is a disease of congenital or acquired narrowing of the distal colon intestinal canal and weakening of peristalsis, which leads to poor passage of feces and stagnation in the proximal intestinal canal, resulting in dilatation and enlargement of the proximal intestinal canal. In terms of treatment, enemas, laxatives and other conservative treatments can be given first, and for patients who are not satisfied with the results of conservative treatments, laparoscopic surgical treatments or open resection of the entire diseased intestinal canal can be performed. If diagnosed with megacolon, please follow the doctor’s instructions for treatment, and actively cooperate to avoid aggravation of the condition, which will bring adverse effects to the body.
