First of all, we need to introduce the defecation reflex, the receivers of defecation we call receptors! The receptors of defecation are mostly concentrated near the dentate line, which is 2.5 cm inside the anus and is the dividing line between the anal canal and the rectum. Internal hemorrhoids are located above the dentate line at the end of the rectum and are formed by the enlarged varicose veins under the mucous membrane at the end of the rectum. The internal hemorrhoid is usually ligated with a ligature, which causes ischemia and necrosis until it falls off. If the damage to the dentate area is heavy during the surgery, defecation disorders do occur within a short period of time after surgery (from the time anesthesia wears off to 10-12 days after surgery). Some patients may have frequent bowel movements, needing to relieve themselves several times a day, having formed stools, or having a feeling of incomplete defecation. Most of these discomforts will gradually disappear with the removal of the ligature. In conclusion, the shallow level of hemorrhoid surgery will not hurt the anal sphincter, so it will not affect the anal contraction. On the contrary, if too much anal skin is removed and too many internal hemorrhoids are ligated during mixed hemorrhoid surgery, not enough mucosal bridges are retained between the hemorrhoid nuclei, and the upper boundary of the trauma is in the same plane after the hemorrhoid nuclei fall off, there may be anal stenosis and defecation difficulties in the future due to scar contracture in the surgical area. In order to prevent anal stenosis caused by too much ligation, the doctor will often finger dilation. So, most of you don’t have to worry if you don’t feel your bowels after hemorrhoid surgery! On the contrary, be aware of post-operative anal stenosis, especially in patients with circumferential mixed hemorrhoids! It is recommended to contact the main surgeon about 7 days after surgery to check the recovery of the opening inside the anus at the right time.
