There is a method surgeons perform to verify what kind of surgery to perform on a patients hemorrhoids.
Sclerotherapy
If hemorrhoids are present, but they are not yet protruding from the opening of the rectal opening, theres a great chance they are mild hemorrhoids that can be cured surgically using a simple injection into each hemorrhoid. The surgical treatment you follow is very familiar to rubber banding, but rather of getting a band, they inject a chemical that will kill the hemorrhoid.
This treatment is called sclerotherapy. This treatment works by injecting a chemical into the hemorrhoid that will block with vessel engorgement and tissue inflammation that causes the hemorrhoids.
If the chemical injected is phenol, then the goal of the surgery is to regulate rectal bleeding.
If the liquid injected inside the hemorrhoids is a salt solution, the hemorrhoid will usually decrease to its normal shape and size.
Hemorrhoid Cauterization
Surgical operation using cauterization includes searing the hemorrhoid with an electrically-charged wire. This is basically used on mild and small hemorrhoids, but rather of injecting, they cauterize.
Infrared Coagulation
Hemorrhoids that do not protrude, or which draws back after protrusion, can be treated using Infrared Coagulation or commonly known as Laser Coagulation Surgery.
Rubber Band Ligation Hemorrhoid Surgery
This is the simplest surgery. It is a rubber band ligation that can be fairly weird but effective.
This type of surgery generally works by tying a strong latex rubber band around the internal or prolapsed hemorrhoids that blocks the blood flow to the entire bulge. With a few weeks, the hemorrhoid will be weakened, gangrened and fall off.
It is quite anxious to think blocking circulation to a body part, but when performed by a surgeon this hemorrhoids surgery is by far the safest, simplest and most effective prolapsed hemorrhoid surgery.
Pain can be extreme if the hemorrhoids are too near the nerve band around the rectal area, so remember to tell your surgeon if you are feeling pain during the ligation.
This kind of surgery is best on medium sized hemorrhoids, as there must be enough skin mass for the rubber band to block.
Hemorrhoid Cryotherapy
This surgical treatment is used when the hemorrhoid is on the state before they reach the level of being outside the rectal opening and for most people, even when the hemorrhoids are showing. The surgery includes the hemorrhoids being deep frozen, then left to dry up and die, very likely to the outcome of the rubber band ligation. Pain lasts up for a couple of weeks.
The Stapling Hemorrhoid Surgery
This surgery is also known as Hemorrhoidopexy and used for internal hemorrhoids that have prolapsed.
Artery Ligation Surgery
This surgical treatment is a non-conventional technique to the more common hemorrhoidectomy, and also an appropriate alternative for all types of hemorrhoid surgeries. Using a specific treatment using ultrasounds, the surgeon determines which arteries are giving blood to the hemorrhoids and then sews up the blood artery closed just above the hemorrhoids. The outcome of this surgery is fairly effective.
