We have become accustomed to hearing the term: minimally invasive. Some patients also request “minimally invasive surgery”. What is minimally invasive surgery? As the name suggests, it is a minimally invasive procedure. However, according to the development of minimally invasive surgery, minimally invasive surgery refers to surgery performed using modern medical devices and related equipment such as laparoscopes and thoracoscopes. The emergence of minimally invasive surgery and its wide application in the field of medicine has been in the last decade or so, and the first case of LC was performed in 1987 by Dr. Mouret in France by chance, not realizing that it marked the birth of a new medical milestone. The concept of minimally invasive surgery is due to the advancement of the medical model as a whole, driven by a “holistic” view of treatment. Minimally invasive surgery focuses on improving and rehabilitating the patient’s psychological, social, physiological (pain), mental outlook, and quality of life, as well as minimizing the patient’s suffering. Since minimally invasive surgery is accomplished by borrowing advanced medical equipment, is it also carried out in the anorectal department? Of course there are, PPH is one of the minimally invasive hemorrhoidal surgery, PPH that is, anastomotic hemorrhoidal circumcision. HCPT (electrocoagulation electrocautery) minimally invasive surgery on hemorrhoids can be a one-time fast and accurate excision of the root cause of hemorrhoids, but also to solve the internal hemorrhoids, external hemorrhoids, mixed hemorrhoids and so on. COOK hemorrhoid gun technology. TST surgery (Tissue-selecting Therapy stapler), also known as selective anastomosis hemorrhoidectomy closure or open-loop minimally invasive hemorrhoidal mucosal resection anastomosis. It is a new technology based on the PPH technology and the improvement of the original operation style, which is characterized by simple operation, mild post-operative pain (almost painless), fewer complications, shorter recovery time, good efficacy and high patient satisfaction. It is known as the latest international surgical program for anorectal diseases. But this so-called “minimally invasive” with the help of “high-tech” surgical instruments is not the “minimally invasive” that I advocate. –They have lost sight of the fact that they are supposed to be enjoying the landscape when they are intoxicated by the fact that high technology is a good wine. What I mean by “minimally invasive” is to achieve the best therapeutic effect at the cost of the smallest and simplest surgical injury and the least amount of surgical pain. The concept of “minimally invasive” should be implemented for all kinds of diseases in the Department of Anorectal Medicine. For example, the most common hemorrhoid surgery, how to cleverly design the incision, as far as possible to protect the normal skin of the anal verge; how to peel off the subcutaneous vein clusters as far as possible, to prevent bleeding and edema; and how to prevent the destruction of the anal glands is too much, resulting in anal dryness and discomfort; how to protect the dentate line, to prevent the sensation of defecation or anal overflow, etc. are the problems that need to be carefully considered. Other anal fistula surgery, how to deal with the inner mouth and fistula, but also to protect the normal tissue; speed up the healing, the root of the lesion, but also to prevent incontinence. A responsible physician should seriously deal with every detail of each patient, the “minimally invasive” concept is implemented throughout.
