Dopple guided hemorrhoid artery ligatoion (DG-HAL) is a new minimally invasive treatment for hemorrhoids that combines ultrasound exploration and suturing surgery as one new treatment technique. It is a new minimally invasive treatment for hemorrhoids that combines ultrasound exploration and stitching surgery. The technique is non-invasive, minimally uncomfortable, does not require removal of hemorrhoidal tissue, is non-invasive, and has rare post-operative complications, preserves the anal lining tissue intact while treating hemorrhoids, maintains the original self-control of the anus, and effectively avoids many complications and serious sequelae that other treatments tend to cause. This world-leading technology is a new type of hemorrhoid surgery carried out in Japan, Europe and the United States in 1995, and is rated by the industry as an “era-creating surgical method in the history of hemorrhoid treatment”. The essence of “DG-HAL hemorrhoid artery ligation” is the high, accurate and selective ligation of the artery supplying the hemorrhoid. The entire procedure is judged by Doppler ultrasound display of the artery, and the inflow/outflow ratio is simultaneously reduced because the venous return is not compromised. As a result, the hemorrhoid will fall off and the bleeding and pain will disappear. …… Safe and reliable: The surgery treats the hemorrhoid while preserving the anal lining tissue intact, keeping the original self-control of the anus unaffected and effectively avoiding the many complications and serious sequelae that other treatments tend to cause, making it a less invasive minimally invasive surgical procedure. Minimally invasive and comfortable: The procedure is non-invasive, with minimal discomfort, no removal of hemorrhoidal tissue, no trauma, rare post-operative complications, and no impact on anal function. Because the ligature site is performed on the dentate line of the anus during the surgery, the nerves here are vegetative and insensitive to pain, so there is no significant pain sensation. The procedure causes minimal damage to the patient because there is no real wound. Hemorrhoid artery ligation Doppler before surgery After surgery
