How Long Does Fissure Surgery Take?

Anal fissures are tiny tears in the lining of the anus, but the pain and discomfort they cause can be overwhelming. They are often associated with constipation, hard stools, prolonged diarrhea, or straining during bowel movements. While many fissures heal on their own or with conservative treatments like ointments, sitz baths, dietary changes, and stool softeners, some fissures become chronic and refuse to heal. In such cases, surgery becomes the most reliable solution.

Understanding Fissure Surgery

Fissure surgery is primarily aimed at reducing the spasm of the anal sphincter muscle and improving blood flow to allow the fissure to heal. The most common procedure is as laser fissure surgery and fissurectomy are also performed depending on the patient’s condition.

How Long Does Fissure Surgery Itself Take?

• Lateral Internal Sphincterotomy (LIS): The most common procedure, typically takes 15 to 30 minutes.

• Laser Surgery for Fissure: Usually even quicker, around 15 to 20 minutes, as lasers cut and seal tissue simultaneously.

• Fissurectomy: Slightly longer, taking around 30 to 40 minutes, since it involves removing the fissure and scar tissue.

• Complex Surgeries (such as flap procedures): May take 45 minutes to 1 hour, especially in cases of chronic or complicated fissures.

• Factors That Affect the Duration of Surgery

While fissure surgery is usually short, several factors can influence how long it takes:

• Type of Surgery: Laser surgery is faster than conventional methods.

• Anesthesia Used: Local anesthesia reduces overall time compared to spinal or general anesthesia.

• Patient’s Health Condition: Patients with other medical issues (such as diabetes or heart problems) may require additional monitoring.

• Complexity of the Fissure: A simple acute fissure is easier to treat compared to chronic fissures with scar tissue, sentinel piles, or associated fistulas.

• Surgeon’s Expertise: Experienced surgeons perform the procedure more efficiently.

• Hospital Setup: Well-equipped centers with modern technology complete procedures faster than facilities with limited resources.

Recovery After Surgery: How Long Until Normal Life?

Recovery Timeline:

• First 24–48 Hours: Mild pain, soreness, or discomfort at the surgical site. Patients are advised rest and sitz baths.

• First Week: Most patients can resume light activities. Laser surgery patients often feel better within a week.

• 2–4 Weeks: Healing progresses significantly. Pain relief is usually complete by this time.

• 4–6 Weeks: Patients can resume all normal activities including exercise, heavy work, and travel.

Comparing Different Surgery Types by Duration

• Laser Surgery: Fastest, both in surgery and recovery.

• Lateral Internal Sphincterotomy (Conventional): Slightly longer recovery but still quick procedure.

• Fissurectomy: Takes more time to heal since the wound is larger.

• Complex Procedures (like advancement flaps): Require longer surgical and recovery times.

Conclusion

So, how long does fissure surgery take? The actual procedure is surprisingly short, often just 15 to 30 minutes, depending on the technique used. However, when you factor in pre-surgical preparation, anesthesia, and post-operative observation.

With modern techniques like laser surgery, the entire process has become faster, safer, and more comfortable, allowing patients to return to normal life with minimal disruption.
