Hemorrhoids surgery falls into different types of hemorrhoid surgery and each has different effects on the hemorrhoid.
If a visible blood clot is formed (as in the case of external hemorrhoids), it can be simply removed with a minimally invasive procedure, which will provide relief. However, if it is a case of a persistent painful and bleeding hemorrhoid that is located internally, you might need an invasive treatment.

There are different types of hemorrhoid surgery that includes both minimally invasive methods and surgical procedures.

Coagulation: Coagulation is a minimally invasive hemorrhoid surgery that is done through laser, infrared rays or using biopolar means. These procedures are the best for internal hemorrhoids as they cause the bleeding hemorrhoid to harden and contract. This surgical procedure has some side effects and increases the chances of recurring hemorrhoids.

Sclerotherapy: This is also known as injection therapy that is carried out by injecting a small amount of chemical solution into the hemorrhoidal tissues in order to shrivel it. It is one of the least painful procedures which might not even cause bleeding.

Rubber band ligation: It is one of the most preferred methods for hemorrhoid treatment. Placing two small rubber bands on the internal hemorrhoid, this method is used to cut off the circulation. This will eventually result in withering of the hemorrhoid. However, this surgery results in bleeding post treatment, but it is not severe in nature.
Stapling: Also known as stapled hemorrhoidectomy, this method blocks the flow of blood to the hemorrhoidal tissues. Stapling is a less painful treatment and the time taken for recovery is also less than some of the major surgeries. But it has been known to be the leading cause of recurrence as well as rectal prolapse, which results in the rectum protruding out of the anus. These options need to be verified by a doctor or suitable qualified medical professional.

Hemorrhoidectormy: It is one of the most popular and the most effective types of hemorrhoid surgery to date. During this surgery, a surgeon removes the excessive tissues from the ano-rectal region that cause bleeding. Using different techniques and mild sedation, hemorrhoidectormy is a complete treatment for the condition. There are various steps to be taken before the procedure to enable the results from the same.

Hemorrhoid surgery is commonly practiced in all four corners of the world. However, as the condition tends to come back time and again, people are now reluctant to opt for surgeries because of this recurring problem. As there are many alternative ways to treat hemorrhoids also people choose to use them instead of a painful and bleeding surgery for hemorrhoid treatment.

And it is absolutely critical that you seek the opinion of your doctor before emabarking on any hemorrhoids surgery or self treatment.
