If you have anal stenosis after hemorrhoid surgery, first of all, don’t be nervous, you should pay attention to your diet and eat more vegetables and coarse fiber foods, which can promote stool formation and reduce symptoms. You can also go to the anorectal clinic to perform index finger dilation. First, you can perform a local massage around the anus to relax the anal sphincter, and then you can extend your index finger with a finger sleeve into the anus and perform full dilation, twice a day for 5-10 minutes, and if necessary, you can put in a disposable anoscope to perform dilation. If the anal stenosis is so severe that the index finger cannot be inserted, timely surgical treatment is needed, and anal stenosis can be released under lumbar anesthesia, or anal dilation can be performed. If the stenosis is caused by local scar adhesions, rectal stenosis adhesion release should be performed, and postoperative anal dilation should be given in time to prevent the stenosis from recurring.
