THD surgery, particularly Transanal Hemorrhoidal Dearterialization (THD), is a minimally invasive procedure used to treat hemorrhoids. This technique focuses on reducing blood flow to hemorrhoidal tissue, thereby reducing swelling and discomfort.
Procedure:
- Anesthesia: THD surgery is typically perform under local anesthesia with sedation or general anesthesia, depending on the patient’s preference and the surgeon’s recommendation.
Technique:
- Insertion of Proctoscope: A specialized proctoscope is inserted into the anus to access the hemorrhoids.
- Doppler Ultrasound: The proctoscope is equipped with a Doppler ultrasound probe to locate the hemorrhoidal arteries.
- Ligation of Arteries: Using Doppler ultrasound guidance, the surgeon identifies the arteries that supply blood to the hemorrhoidal cushions. These arteries are then ligated (tied off) using sutures or a special thread that also delivers a gentle electrical current to seal the artery.
- Shrinkage of Hemorrhoids: By reducing the blood flow to the hemorrhoidal cushions, the procedure aims to shrink and reduce the size of the hemorrhoids.
Advantages:
- Minimally Invasive: The surgery is perform through the anal canal, avoiding the need for external incisions.
- Reduced Pain: Patients typically experience less pain compared to traditional hemorrhoidectomy.
- Shorter Recovery: Recovery time is generally quicker, with most patients able to resume normal activities within a few days.
- Low Risk of Complications: There is a lower risk of complications such as anal stenosis (narrowing of the anal canal), which can occur with more invasive procedures.
Effectiveness:
- THD surgery is effective for treating grades 2 and 3 hemorrhoids (those that protrude through the anus during bowel movements).
- Long-term success rates are generally good, with many patients experiencing relief from symptoms.
- Studies and clinical use have shown that THD surgery effectively manages hemorrhoidal symptoms and reduces the recurrence rate, making it a reliable option for long-term relief.
Versatility:
- THD can be use to treat various grades of hemorrhoids, from less severe internal hemorrhoids to more advanced cases that might traditionally require more invasive surgery.
Conclusion:
THD surgery offers a less invasive alternative to traditional hemorrhoidectomy for treating symptomatic hemorrhoids. It is important to consult with a colorectal surgeon to determine if THD surgery is appropriate for your specific condition and to discuss the potential risks and benefits.
