Tissue-selecting Therapy stapler (TST) is a new method based on the theory of “downward migration of anal cushion”, combined with the theory of “varicose veins” into hemorrhoids, and absorbed It is a new method that is more in line with the characteristics of the pathological changes of hemorrhoids and the functional needs of the anus, based on the modern concept of hemorrhoid treatment, combined with the advantages of Chinese medicine ligation method. Compared with PPH, TST is a holistic solution based on different hemorrhoid formation theories. The operation of TST is to make a full or half-load or “point suture” 2-3 cm above the dentate line according to the number and size of hemorrhoid nuclei, and to draw in the upper 1/3 of the hemorrhoid at the same time to remove the rectal mucosa and part of the hemorrhoid body on the hemorrhoid, and to “cut off the flow” at the same time “The TST is a more effective treatment than PPH. Compared to PPH, TST is a more varied procedure for different numbers and sizes of hemorrhoids. The TST procedure is a continuation and extension of the minimally invasive approach to hemorrhoids, and retains the advantages of the PPH procedure in terms of less trauma, less postoperative pain, faster recovery, and lower postoperative complications and recurrence rates. The PPH procedure has the following advantages: 1. The scope of mucosal excision on hemorrhoids can be adjusted according to the number and size of hemorrhoid nuclei to achieve a good suspension effect. 2. Controlled removal of part of the apical tissue of the hemorrhoid nucleus reduces the arterial blood flow in the anal cushion and achieves the effect of reduction of accumulation. Compared with PPH, TST is a further development of minimally invasive treatment methods for hemorrhoids by maximizing the preservation of normal mucosal bridges and maintaining the fine sensory and contractile functions of the anus. tST, a unique technological innovation, currently holds 10 international and domestic patents. Although TST is developed on the basis of PPH, it has surpassed the realm of PPH in terms of academic theory and product quality, reaching a new level of hemorrhoid treatment. As a Chinese physician, I am very proud to see the high quality of domestic TST going to the world! Since May 2011, I have carried out nearly 20 cases of TST surgery, and the surgical results are comparable to PPH, but the adverse reactions are significantly less than PPH, and the minimally invasive effect is more obvious, only that the price is more expensive than PPH, so it is difficult to promote it universally.
