Hemorrhoid surgery is now routinely performed with mixed hemorrhoids with external stripping and internal ligation, hemorrhoid artery ligation, RPH, and PPH. After the hemorrhoid is removed, the anal scar will form and the elasticity of the anus will be worse than before, and the scar will soften after two months. Hemorrhoid surgery will not cause anal stenosis because the surgery does not involve the sphincter muscle, unless the opening taken is particularly large, but the probability of anal stenosis occurring in this case is still very low. If the anal stenosis occurs, the anus needs to be dilated, but in general, it will not be stenosed and does not need to be dilated, the incision will grow naturally in about three weeks, and the hospital will follow up regularly after the surgery.
