After surgery for hemorrhoids, most patients do not need anal dilation, and only a small number of patients can be considered for dilation after surgery, mostly in the following cases: 1. The relatively large number of removed hemorrhoid nuclei, more than two, or even more when local scars are easily formed, regular dilation helps prevent anal stenosis and can reduce postoperative complications. 2. Taking dilation is mainly for minimally invasive use of PPH, RPH, that is anastomotic mucosal circumferential resection patients. As the loop anastomosis is prone to rectal mucosal hyperplasia and scar stenosis, dilation after surgery should be performed at this time to help reduce the possibility of scar formation stenosis. Whether or not you need to dilate your anus after hemorrhoid surgery, you must go to a regular anorectal hospital for detailed consultation and treatment.
