Megacolon laxity can be treated with medication, dilatation and surgery depending on the severity. Megacolon is mostly due to the lack of intestinal ganglion cells, resulting in the narrowing of the distal colon, reduced peristalsis, poor passage of feces, and accumulation of feces in the proximal intestine, leading to dilatation and thickening of the intestine. Megacolon clinically manifests as persistent constipation, abdominal distension, and in severe cases, the accumulation of feces can lead to enteritis and intestinal perforation. Oral probiotics, lactulose and other medications can be taken, or can be used to open the anal plug, saline enema, anal dilator to expand the anus and other ways to laxative. Those who are not effective in conservative treatment should go to regular hospitals and undergo surgery after evaluating the indications for surgery. If constipation, bloating, abdominal pain and other symptoms are not relieved, or accompanied by other symptoms, you should go to the hospital in a timely manner, to identify the cause of the targeted treatment, the drug should be used under the guidance of a doctor.
