The current surgical technique used for hemorrhoids is known as PPH, which has created a milestone procedure for hemorrhoid treatment. Many patients tend to rush, of course, as the Bank does not deny the unique efficacy and role of the procedure, the treatment of severe hemorrhoids is very obvious, but we have observed in the clinic a few patients after surgery to defecation difficulties, from a professional point of view, the reason may be related to the surgical removal of the mucosa on the hemorrhoids for a week, because a circle of mucosa on the hemorrhoids removed and at the same time anastomosis nail double row of pins for anastomosis, after the healing of the anastomosis may form A circle of scar tissue, the loss of the original tissue elasticity, when people defecate through here easily obstructed, the patient needs to force to expel, over time the formation of constipation symptoms, the heavy may need surgery to correct. We have encountered this case in our clinical practice. In recent years, a TST open-loop hemorrhoidectomy device was designed by Suzhou Tianshen, which avoids the problem of difficult anal defecation caused by PPH, with less bleeding, less trauma, easy healing, short operation time, quick recovery, short hospital stay, and reliable efficacy. Our hospital has successfully completed more than thirty cases, and the patients reflected well that after six months, the bowel movement is satisfactory, the number of normal stools, formed stools are the main, there is no sense of incontinence, strong sense of bowel control, basically achieve the preoperative bowel function, is a new technique of hemorrhoids with potential, and its indications can be extended to first, second and third degree hemorrhoids can use this method.
