① Slow recovery and postoperative pain:
The principle of laser treatment of hemorrhoids is to use light energy to produce high-temperature carbonization to cut hemorrhoid tissue.
Therefore, when we use laser to remove hemorrhoids, the surface of the wound left behind is also necrotic due to high temperature burning, so the actual wound surface is enlarged.
After superficial necrotic tissue falls off, it is easy to cause massive bleeding, which often occurs about 2 weeks after operation, causing great pain and even life-threatening to patients.
The wound began to heal after the eschar fell off, so the healing time was greatly delayed.
Laser treatment of hemorrhoids also needs to be operated under anesthesia. Of course, the operation is painless. However, due to high temperature, local tissue proteins coagulate, tiny blood vessels and lymphatic vessels are blocked, and local edema is obvious, so the postoperative pain is more severe than that of general surgery.
(2) Laser belongs to the category of instruments, and it needs to be familiar with various performances to reduce accidents, and its controllability (such as laser dose and precise positioning of surgery) is not as easy to master as surgery;
(3) Laser can't stop bleeding in deep wounds, and ligation is still needed twice to stop bleeding;
④ Intraoperative cutting and punctate cauterization must be accurate and the depth must be well controlled, otherwise normal skin or muscle tissue will be easily damaged, resulting in adverse consequences;
⑤ Laser hemostasis is timely, but scabs fall off after a period of operation, which is easy to bleed.
Advantages of laser treatment of hemorrhoids
The specific methods of laser therapy can be divided into laser cutting, laser cauterization, laser irradiation and laser acupuncture.
Although laser cutting has many complications in hemorrhoidectomy, if low-power and far-focus irradiation is applied to physical therapy, it will accelerate local blood circulation and improve metabolism and tissue nutrition.
This will obviously improve hemorrhoid inflammation, anal edema and slow wound healing.
So at present, many hospitals no longer use its "cutting hemostasis" function, but use its "improving blood supply and promoting metabolism" function.
