Piles surgery is any procedure that removes, shrinks, or repositions swollen blood vessels (hemorrhoids) in and around the anus when non-surgical treatments have failed. Most people with hemorrhoids never need an operation. Surgery is typically reserved for grade III and IV hemorrhoids, where the swollen tissue protrudes from the anal canal and either needs to be pushed back in manually or stays out permanently. It may also be recommended for lower-grade hemorrhoids that keep bleeding or causing symptoms despite dietary changes, fiber supplements, and office-based treatments like rubber band ligation.
When Surgery Becomes Necessary
Hemorrhoids are graded on a four-point scale. Grade I hemorrhoids bleed but don’t protrude. Grade II protrude during a bowel movement but slide back on their own. These two grades almost always respond to increased fiber, better hydration, and in-office procedures. Grade III hemorrhoids protrude and need to be pushed back in by hand, while grade IV hemorrhoids are permanently prolapsed and can’t be pushed back at all. Clinical guidelines consistently recommend surgery for grades III and IV, or for patients at any grade whose symptoms persist after conservative care.
Traditional Hemorrhoidectomy
The most established surgical option is excisional hemorrhoidectomy, where the surgeon physically cuts out the swollen hemorrhoidal tissue. There are two main versions. In the closed technique (sometimes called Ferguson hemorrhoidectomy), the wound is stitched shut after the tissue is removed. In the open technique (Milligan-Morgan hemorrhoidectomy), the wound is left open to heal on its own. The closed approach is more common in the United States, while the open technique is widely used in the UK and Europe.
A meta-analysis of 11 randomized controlled trials involving over 1,300 patients found that the closed approach was associated with less postoperative pain, faster wound healing, and less bleeding afterward. Both techniques, however, had similar rates of complications, recurrence, and infection. Traditional hemorrhoidectomy is considered the most thorough option and carries the lowest long-term recurrence rates, but it also involves the most painful recovery.
Stapled Hemorrhoidopexy
Stapled hemorrhoidopexy, first described by Italian surgeon Antonio Longo in 1998, takes a fundamentally different approach. Rather than cutting out the hemorrhoids themselves, a circular stapling device removes a ring of tissue from inside the rectum above the hemorrhoids. This pulls the swollen cushions back up into their normal position inside the anal canal, like hoisting a curtain back onto its rail. The staple line acts as a new anchoring point that eventually gets replaced by the body’s own scar tissue, holding everything in place permanently.
The procedure also interrupts the blood supply feeding the hemorrhoids, which causes them to shrink over time. Because the staple line sits in an area with fewer pain-sensing nerves (above what’s called the dentate line), patients generally experience significantly less pain than with traditional hemorrhoidectomy. The operation itself is done somewhat blindly, since the surgeon can’t see inside the stapler head as it fires, making precise placement of a guiding stitch beforehand critical to the outcome. Studies comparing stapled hemorrhoidopexy with traditional surgery show similar one-year recurrence rates for grade III and IV hemorrhoids.
Doppler-Guided Artery Ligation
This newer technique, often called THD (transanal hemorrhoidal dearterialization), uses an ultrasound probe to locate the six main arteries feeding blood to the hemorrhoids. Once identified, each artery is stitched shut through a specialized scope inserted into the anal canal. For patients with prolapsing tissue, the surgeon adds a second step called mucopexy: a running stitch that gathers up the loose, drooping tissue and lifts it back into position.
The entire procedure is done without removing any tissue, which means no open wounds and less postoperative pain. It works well for grade II and III hemorrhoids, though results for grade IV can be less reliable. Because the stitching is done in the less sensitive upper portion of the anal canal, most patients find recovery considerably easier than with traditional surgery.
Laser Hemorrhoidoplasty
Laser hemorrhoidoplasty delivers laser energy directly into the hemorrhoidal tissue through a thin fiber, causing controlled shrinkage from the inside while leaving the surrounding skin and lining intact. The average procedure takes about 18 minutes with minimal blood loss. In prospective studies, pain scores dropped from a mild 2.1 out of 10 on the first day to just 0.3 by day seven. The median recovery time was three days, and symptom scores improved dramatically at the three-month mark. One study found no recurrences at 12 months, with results comparable to traditional surgery but far less pain and a much faster return to daily life.
What Recovery Looks Like
Recovery depends heavily on which procedure you have. Traditional hemorrhoidectomy has the longest and most uncomfortable recovery. The worst pain typically hits with your first bowel movement after surgery, then improves noticeably after three days and continues to fade over the next two weeks. Most people say their pain is gone within two weeks, and the average full recovery takes two to four weeks. Returning to heavy exercise or physical labor may take six to eight weeks.
Stapled and Doppler-guided procedures generally allow a faster return to normal activities, often within one to two weeks. Laser hemorrhoidoplasty has the shortest downtime, with most patients back to their routine within three days.
Regardless of technique, the first few bowel movements are the hardest part. Laxatives and stool softeners make a real difference here. Studies show that using bulk-forming or osmotic laxatives after surgery leads to earlier, less painful bowel movements compared to waiting for things to happen naturally.
Managing Pain After Surgery
Pain management after hemorrhoid surgery has improved significantly. Beyond standard painkillers, several topical treatments applied directly to the surgical site can meaningfully reduce discomfort. Ointments that relax the anal muscles (like those containing diltiazem) have been shown to cut pain scores substantially during the first four days. Topical numbing cream provides relief in the first 24 hours. A topical form of the antibiotic metronidazole reduces pain throughout the first two weeks and also helps prevent infection. Sucralfate ointment, applied once or twice daily for two weeks, both reduces pain and speeds wound healing.
Warm sitz baths (sitting in a few inches of warm water for 5 to 10 minutes) are routinely recommended and do relax the anal muscles for up to 70 minutes afterward, though clinical trials haven’t been able to confirm they reduce pain scores compared to skipping them. Many patients still find them soothing.
Risks and Complications
The most common complication after hemorrhoidectomy is difficulty urinating. In a study of over 2,100 patients, about 14% experienced temporary urinary retention after surgery, typically requiring a catheter for a short period. This resolves on its own and is thought to result from a combination of anesthesia effects and reflex spasm in the pelvic muscles.
Postoperative bleeding occurs in a small percentage of cases, usually within the first week. It’s rarely severe enough to require a return to the operating room. Narrowing of the anal canal (anal stenosis) is a longer-term risk that can develop if too much tissue is removed, but it’s uncommon with experienced surgeons. Infection rates are low across all techniques. Minimally invasive options like laser and Doppler-guided procedures carry lower complication rates overall than traditional excision.
Preparing for the Procedure
Preparation for hemorrhoid surgery is simpler than for major bowel operations. Current evidence suggests that a full mechanical bowel prep (the extensive cleaning out required before colonoscopy, for example) is not necessary. Most surgeons ask you to use a small enema a few hours before the procedure to clear the lower rectum. You’ll typically fast from midnight the night before if you’re having general or spinal anesthesia. Your surgeon may ask you to stop blood thinners several days in advance, so be upfront about every medication you take, including over-the-counter pain relievers and supplements. Many hemorrhoid procedures are done as day surgery, meaning you go home the same day.
