Hemorrhoid surgery is not considered dangerous for most patients. In a study of 2,840 hemorrhoidectomy procedures, the overall complication rate was 3%, and deaths are extraordinarily rare. That said, the surgery does carry real risks worth understanding, and the recovery is more uncomfortable than many people expect. Here’s what the evidence shows about the specific risks and what recovery looks like.
Overall Complication Rates
Across nearly 3,000 hemorrhoidectomy cases analyzed in the Journal of Coloproctology, 97% of patients had no surgical complications at all. Among the 3% who did, the most common issues were narrowing of the anal canal (1.8%), significant bleeding (0.8%), weakened muscle control around the anus (0.2%), and serious infection (0.1%). These rates held steady regardless of which surgical technique was used.
Serious adverse events, including complications that required hospitalization or additional procedures, occur in roughly 7% to 9% of cases depending on the method. That number is higher than the 3% figure because it includes problems like urinary retention and pain management issues that aren’t strictly “surgical” complications but still affect your recovery.
The Risk of Losing Bowel Control
One of the most feared outcomes is fecal incontinence, and it does happen, though uncommonly. A meta-analysis of multiple studies found that in the first three months after surgery, about 5% of patients in clinical trials experienced some degree of incontinence. This often involves minor leakage or urgency rather than complete loss of control.
The good news is that the rate drops over time. After three months, roughly 1.4% to 2.5% of patients still reported incontinence symptoms. For most people, early bowel control issues resolve as the surgical area heals and swelling goes down. Permanent loss of continence is possible but uncommon.
Anal Narrowing After Surgery
The single most common long-term complication is anal stenosis, a narrowing of the anal canal caused by scar tissue. About 90% of all anal stenosis cases stem from hemorrhoid surgery, and it develops in 1.5% to 3.8% of hemorrhoidectomies. Symptoms include difficulty passing stool, thin stools, and pain during bowel movements. When it does occur, it can usually be treated, sometimes with gradual dilation and sometimes with a corrective procedure.
Life-Threatening Complications Are Extremely Rare
Deaths from hemorrhoid surgery exist in the medical literature, but they are vanishingly rare. A review of severe complications from stapled hemorrhoid surgery identified only 13 patients worldwide over a decade who needed emergency abdominal surgery due to complications, and three of those patients died from overwhelming infection in the days following their procedure. The causes included bowel perforation, sepsis, and a severe soft-tissue infection called Fournier’s gangrene.
These cases are worth knowing about because they underscore why post-operative warning signs matter. Fever, increasing pain (rather than gradually improving pain), inability to urinate, or signs of infection in the days after surgery all warrant urgent medical attention. Catching complications early is what prevents them from becoming dangerous.
Stapled vs. Traditional Surgery
There are two main approaches: traditional excisional surgery, where the hemorrhoid tissue is cut away, and stapled hemorrhoidopexy, where a circular stapling device repositions the tissue. A large randomized trial published in The Lancet compared the two head-to-head and found some notable differences.
Stapled surgery was less painful in the first three weeks. However, traditional excisional surgery produced better long-term results. At 24 months, patients who had traditional surgery reported fewer recurring symptoms and better continence. Recurrence was significantly higher in the stapled group: 134 out of 317 patients reported recurrence at two years, compared to 76 out of 300 in the traditional surgery group. Complication rates between the two methods were similar, and return-to-activity timelines were about the same at six weeks.
In short, stapled surgery trades less early pain for a higher chance of needing another procedure down the road.
Urinary Retention: A Common Surprise
One complication that catches many patients off guard is difficulty urinating after surgery. The incidence of urinary retention after hemorrhoidectomy ranges from 25% to 35%, making it far more common than any of the surgical complications listed above. Men are affected much more often than women, with 12% of men experiencing it compared to 3% of women in one study. It’s typically temporary and resolves within a day or two, but some patients need a catheter in the short term. Pre-treatment with certain medications that relax the bladder can reduce the risk dramatically, from about 24% down to under 4%.
What Recovery Actually Feels Like
The surgical risks may be low, but the recovery is genuinely rough for many people. Expect the anal area to be painful or aching for two to four weeks. Most patients need one to two weeks off work, though that varies depending on how physically demanding your job is. Sitting for long periods is uncomfortable early on, and bowel movements can be painful for the first week or two.
Pain management, stool softeners, sitz baths, and a high-fiber diet are the standard approach during recovery. The first bowel movement after surgery is often the most dreaded part of the process, but keeping stools soft makes a meaningful difference. By six weeks, most patients are back to normal activity regardless of which surgical technique was used.
