Hemorrhoids are enlarged vascular tissue in your lower rectum and anus. That’s the opening at the end of your large intestine through which stool leaves your body. Everyone has hemorrhoids. They don’t cause problems unless they swell up, however. Swollen hemorrhoids can cause itching and pain around your anus that can make bowel movements uncomfortable.
A thrombosed piles is when a blood clot forms inside a hemorrhoid. This condition isn’t dangerous, but it can be painful.
This procedure removes the hemorrhoid, along with the clot and blood vessels. You may get a spinal block, which numbs the area of surgery, or you might be asleep under general anesthesia during this procedure. This procedure is more invasive and takes longer to perform than an external thrombectomy, but the hemorrhoid is less likely to come back. It’s usually only done for the most severe hemorrhoids because it causes much more pain. Side effects of this surgery include pain, urinary tract infections, and trouble emptying your bladder.
This procedure is also done while you’re asleep under general anesthesia. The surgeon uses a stapling instrument to put the hemorrhoids back in place and hold them there.
