Frequent localized sensation of defecation in the anus may lead to the presence of fecal residue, and anoscopy may be an option. If there is fecal residue, the patient can be instructed to strain to pass stool. If the patient is unable to pass stool by force, warm saline enema can be chosen to lubricate the stool to avoid further stool blockage, which may lead to symptoms of incomplete intestinal obstruction in the intestine. If the fecal accumulation is discharged, it is considered possible that there is an increase in the size of internal hemorrhoids, which compress the local skin of the anus, or due to too much relaxation of the rectal mucosa, and the differential diagnosis can be clarified by anoscopy with fecal contrast examination. When the above diseases reach the symptoms of localized anal compression, they need to be removed surgically to relieve the symptoms, and simple topical medication can only temporarily relieve the symptoms, and cannot achieve a cure.
