Since PPH was introduced into China at the end of the last century, it has carried the aura of “minimally invasive” and then rapidly spread throughout the country. It is also synonymous with the latest pathogenesis of hemorrhoids: the “anal cushion downward migration theory”, which protects the anal cushion and reduces pain, and gradually becomes synonymous with minimally invasive hemorrhoid surgery. In fact, anorectal surgeons know that the surgical trauma of PPH is not small, and the trauma formed by the surgery is a 4cm wide circumferential trauma, about as big as a business card. The actual hemorrhoid surgery can be considered “minimally invasive” with such a large trauma, and post-operative hemorrhage can be hundreds or even thousands, with Fay moisture shock. It’s not as bad as the traditional surgery of LU. then why is it called minimally invasive? That is because the trauma is above the tooth line, where the nerves do not feel pain, so it should be called “minimally painful”, but “minimally painful” is not the same as “minimally invasive”, these two concepts are easy to be confused. These two concepts can be easily confused. “Minimally painful” may not be “minimally invasive”, and the risk of postoperative complications is still great. “Minimally invasive” should include “minimally painful”, while “minimally painful” is not necessarily “minimally invasive”. I think PPH surgery should be called “minimally painful”, not “minimally invasive”. The phrase “treat as you go, no delay in work” is very irresponsible and even dangerous for the patient.
