In 1975 Thomson proposed the theory of anal cushion subluxation and it gradually became accepted, and there is a convergence of understanding regarding the surgical treatment of hemorrhoids. Asymptomatic hemorrhoids do not require treatment, and treatment of symptomatic hemorrhoids is aimed at eliminating or relieving symptoms, primarily by correcting pathophysiologic changes, rather than eradicating pathologically altered anal pads. It is with the concept of painless and minimally invasive that the RPH procedure has been rapidly developed. Treatment principles: (1) mucosal wrinkling after ligation, the anal pad is lifted; (2) local inflammatory reaction causes adhesion of mucosa, submucosa and superficial muscle layer, and the anal pad is fixed in a higher position; (3) partial blockage of blood supply to hemorrhoids or reduction of venous backflow reduces congestion and hypertrophy or stagnation of blood flow in hemorrhoids, causing the hemorrhoid mass to atrophy; (4) direct ligation of the upper edge of the base of the hemorrhoid mass can stop bleeding immediately. According to our experience, we should pay attention to the following problems during the operation: (1) the ligature should be 1-3 cm on the dentate line, the distance is too far to make the anal cushion suspension inadequate, and the hemorrhoid retraction is incomplete after the operation; the distance is too close to damage the anal cushion and produce pain. (2) At least 0.5 cm distance should be left between two ligature points to avoid affecting the healing. (3) Patients should be instructed to avoid strenuous exercise for 3 weeks after surgery to avoid bleeding after the ligature tissue is dislodged. The data of this group show that RPH has the advantages of easy operation, short operation time, mild postoperative pain and quick postoperative recovery. This procedure causes minimal damage to the patient and can be performed under local anesthesia or even without anesthesia, which further reduces the possible negative reactions and the postoperative recovery time. The shorter hospital stay, lower complication rate, and less postoperative pain make it more suitable as an outpatient surgical procedure and, at the same time, meets the requirements of minimally invasive surgery, which is worthy of clinical promotion.
