Anal Stenosis After Hemorrhoid Surgery: Symptoms and Definitions - Surgery

Anal issues


Dear Doctor,
I underwent traditional hemorrhoidectomy two months ago, and recently I've been experiencing some tightness in the anal area during bowel movements.
It feels especially worse when I haven't taken Laxacoma Plus, as my stools become harder and more difficult to pass.
I find myself exerting more effort than before to complete my bowel movements.
Additionally, when sitting down, the pressure from the chair on my anus causes a slight pain.
Could this be a sign of anal stenosis following the surgery? What is the definition of anal stenosis? How many fingers should be able to be easily inserted to not be considered anal stenosis? Thank you.

Best regards,
Red Bean

Hello: In response to your question, anal stenosis is a complication that can occur after hemorrhoid surgery.
It was more common during the first half of the twentieth century when circular hemorrhoidectomy was prevalent.
Nowadays, with wedge resection being the mainstream approach, anal stenosis has become less common.
Traditional cryotherapy can also potentially lead to anal stenosis.
The definition of anal stenosis is the inability to insert even a single finger into the anus, accompanied by severe pain during defecation.
Based on your description, it appears that you do not have anal stenosis.

More Info


After undergoing traditional hemorrhoid surgery, it's not uncommon for patients to experience various symptoms related to bowel movements, including the sensation of tightness in the anal area, especially when passing stool. Your description suggests that you may be experiencing anal stenosis, which is a narrowing of the anal canal that can occur after surgical procedures involving the rectum or anus.

Understanding Anal Stenosis:
Anal stenosis can manifest as difficulty in passing stool, a feeling of tightness or pressure in the anal region, and sometimes pain during bowel movements. The condition can arise due to scar tissue formation following surgery, which can lead to a reduced diameter of the anal canal. This can make it more challenging for stool to pass, especially if it is hard or bulky, as you noted with the use of medications like Laxaclear Plus.

Definition of Anal Stenosis:
Anal stenosis is defined as a significant narrowing of the anal canal that can impede the passage of stool. While there is no universally accepted measurement for the degree of narrowing that constitutes stenosis, a practical guideline is that if the anal canal can accommodate a finger comfortably (typically around 1-2 fingers), it is generally considered normal. If you find that you cannot insert a finger or that it is painful to do so, this may indicate a degree of stenosis.

Symptoms and Management:
The symptoms you are experiencing—tightness, pain during bowel movements, and the need to exert more effort to pass stool—are consistent with anal stenosis. It is essential to address these symptoms to prevent further complications, such as fecal impaction or anal fissures, which can arise from straining.

Here are some recommendations for managing your symptoms:
1. Dietary Adjustments: Ensure that you are consuming a high-fiber diet to help soften your stool. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Staying well-hydrated is also crucial.

2. Stool Softeners: If you find that your stool is consistently hard, consider using over-the-counter stool softeners or laxatives as needed, but consult your healthcare provider for recommendations tailored to your situation.

3. Gentle Anal Care: After bowel movements, ensure that you are cleaning the area gently to avoid irritation. Warm sitz baths can also provide relief and promote healing.

4. Follow-Up with Your Surgeon: It is essential to communicate your symptoms to your surgeon or healthcare provider. They may recommend further evaluation, such as a physical examination or imaging studies, to assess the degree of stenosis and determine the best course of action.

5. Physical Therapy: In some cases, pelvic floor physical therapy can be beneficial in addressing issues related to anal tightness and improving bowel function.

6. Surgical Options: If conservative measures do not alleviate your symptoms, your healthcare provider may discuss surgical options to relieve the stenosis, such as dilation procedures or surgical revision.

In conclusion, while your symptoms may indicate anal stenosis following hemorrhoid surgery, it is crucial to seek professional evaluation and management. Early intervention can help prevent complications and improve your quality of life. Always consult with your healthcare provider for personalized advice and treatment options.
