With the rapid development of modern technology and the improved understanding of the anatomical structure of the anorectum, the mechanism of occurrence of hemorrhoids as pathologically proliferated, hypertrophied, and displaced anal cushion tissue has been studied in depth, and the concept of minimally invasive is gradually gaining popularity, and many anorectal surgeons have made minimally invasive surgery and protection of anal function a guideline that must be followed. There are many minimally invasive procedures for hemorrhoids, but each has its own indications, and it is quite important to choose the best minimally invasive procedure. The advantage of injection therapy, which is a non-surgical treatment commonly used at home and abroad, is that the treatment effect can be compared with surgery, with less pain and shorter treatment time, and is suitable for stage I-II internal hemorrhoids, especially effective for bleeding symptoms. Although laser therapy can treat stage I-II internal hemorrhoids, it is easy to damage the muscles; infrared coagulation can stop bleeding, but it is not as fast as injection therapy; cryotherapy is less effective and the postoperative pain is obvious, so the above three physical therapies are less used at present. RPH: It has the characteristics of “simple, convenient, inexpensive and experimental” and is mainly applicable to the internal hemorrhoids of stage I, II, III and mixed hemorrhoids. Clutch haemorrhoidopexy (PPH): The supra-hemorrhoidal mucosa is removed circumferentially by special surgical instruments, and the prolapsed anal cushion is surgically repositioned instead of anatomically removing the hemorrhoid as thoroughly as possible in the past. Indications for surgery: Stage III and IV prolapsed internal hemorrhoids and circumferential mixed hemorrhoids with mainly internal hemorrhoids, with the disadvantage of residual dermatomes that affect the aesthetics. Ultrasonic Doppler-guided hemorrhoid artery ligation (DG-HAL): A special device is used to determine the location of the hemorrhoid artery and suture it to achieve rapid hemostasis and shrinkage of the hemorrhoid body, which is extremely effective for bleeding hemorrhoids. In fact, the aim of treatment of symptomatic hemorrhoids is to eliminate or relieve symptoms, not to cure the pathologically altered anal cushion, precisely because the anal cushion plays such an important role in the process of stool control that conservative and non-surgical treatment must be intensified from the point of view of maintaining the integrity of the anal cushion and the anal canal mucosa. Surgical treatment should be considered only after conservative treatment has failed, and surgical treatment should not destroy or minimize the destruction of the anal cushion tissue. The general trend in the treatment of hemorrhoids is to use a combination of Chinese and Western medicine, non-surgical and surgical therapies, and minimally invasive and painless comprehensive treatment methods. It can be seen that for different people, different stages of hemorrhoids, different quality of life requirements, reasonable choice of appropriate minimally invasive surgery, with good living and defecation habits, only to help hemorrhoids completely cured.
