If too much tissue is removed during the external stripping and internal ligation of circumferential mixed hemorrhoids surgery, a bridging healing may occur resulting in anal stenosis during the wound healing period, which is usually around one month. Anal stenosis does not occur in all cases of external stripping and internal ligation of circumferential mixed hemorrhoids, but some patients may develop anal stenosis, which is a complication of hemorrhoid surgery. The main reason for the development of anal stenosis is that when surgical excision of hemorrhoids is performed, too much perianal skin or perianal mucosa is removed, which leads to anal stenosis during the post-surgical recovery period, usually around one month, when there is localized fibrosis and blocky scars during the healing of the post-surgical incision. For patients who have already developed anal stenosis, the symptoms can be improved by actively expanding the anus, and in serious cases, surgical treatment is required. Patients who undergo external stripping and internal ligation of circumferential mixed hemorrhoids should try to undergo treatment in regular hospitals to effectively prevent the occurrence of anal stenosis. If anal stenosis occurs after the operation, you need to consult a doctor in time and actively treat it to avoid aggravation of the condition.
