After having rectal mucosal prolapse surgery for two years, the scar affects the difficulty of defecation, which can be helped by anal dilation, and patients with severe stenosis can have the stenosis lifted surgically, in addition to dietary adjustments to soften the stools. After surgery for rectal mucosal prolapse, due to scar proliferation at the surgical incision, therefore it can lead to localized narrowing of the rectal lumen, which in turn leads to difficulty in defecation. In the case of mild stenosis, the bowel movement can be facilitated by improving the diet, increasing the intake of foods rich in dietary fiber, and taking lactulose oral solution to soften the stool. Patients with mild rectal stenosis can also use finger dilation to assist in bowel movement. For severe rectal stenosis, if the above methods are ineffective, surgery can be considered to relieve the stenosis. After surgery for rectal mucosal prolapse, patients who have difficulty passing stools due to scarring should seek medical attention if the symptoms of difficult bowel movements continue to be unrelieved.
