The sequelae of PPH hemorrhoid surgery are mainly rectal stenosis, intestinal foreign body sensation, bleeding, etc., as follows: First, rectal stenosis: because its surgical area is located in the lower rectum, also known as hemorrhoid circumferential mucosal resection stapling, its postoperative anastomosis will be produced, if the anastomosis local scar growth is too much, it may lead to anastomotic stenosis, which will lead to postoperative defecation difficulties, defecation foreign body sensation, and Second, foreign body sensation in the rectum: PPH surgery requires the use of titanium nails for the anastomosis, and although the nails are very small, there will be local residues that can produce foreign body sensation in the rectum; Third, bleeding: the anastomosis may have bleeding symptoms after surgery, and in serious cases, re-operation is needed to stop bleeding.
