Inguinal Hernia Repair: Why Tension-Free Techniques May Not Be Used - Urology

Hernia repair surgery


Dear Dr.
Lin,
Hello! If it's convenient, I would like to ask you a few questions.
Recently, I underwent "hernia repair surgery."
Question 1: I have an "inguinal hernia (left scrotal swelling)" and I'm only 22 years old.
How could this happen? It seems inconsistent with what I've learned, as "children" and "elderly males" are the majority affected.
The former usually have developmental issues in the abdominal wall, where a gap that should have closed remains wide open; the latter experience muscle atrophy, causing previously closed gaps to become loose or weak, especially with increased abdominal pressure.
How could a young person like me have this? Moreover, there were no warning signs during the latent period! I don't know if it was due to "abdominal pressure during bowel movements," "abdominal pressure during nocturnal emissions (which often occurred in middle and high school)," or "abdominal pressure from sit-ups and push-ups" that caused this...
Question 2: I recently had hernia repair surgery, and the doctor said that since I am considered an "adult," they should have used a tension-free repair (TFR) to enhance the strength of the fascia.
However, my parents told me that my surgery lasted less than 30 minutes! As a medical student, I feel that if TFR was used, it wouldn't have been so quick.
When I asked the doctor why TFR wasn't used, he smiled and said, "You don't need it." He only addressed the opening and said it was similar to an indirect hernia.
I asked again, "Isn't that going to increase the recurrence rate?" The doctor just smiled and said, "No, it won't." I was taken aback.
I secretly asked a nearby intern the same question, and he replied, "It seems like your fascia isn't torn." I didn't understand that either.

Dr.
Lin, could you please help me understand why the surgeon didn't use TFR? What are your thoughts? I'm really afraid of a recurrence.
I'm a bit angry and confused about why it wasn't used.
As a medical student, I remember that according to what I've learned and researched, the traditional surgical method is tissue-to-tissue repair.
This usually involves excising the hernia sac and pushing the protruding tissue back into the abdominal cavity.
The surgeon then repairs the abdominal wall by pulling the surrounding muscles together to cover the defect, using several sutures to secure the muscles.
This method directly sutures the tissue (such as Bassini, Halsted, Andrews, McVay, Iliopubic tract repair, and Shouldice surgeries), resulting in stronger postoperative pain, a higher recurrence rate, and longer recovery times, with a recurrence rate of 10-15%.
On the other hand, tension-free repair (TFR) is defined as a repair process that does not rely on the force of sutures to pull tissues together but instead uses a prosthetic mesh or device to replace or reinforce the tissue defect.
This method reduces tension on the surrounding muscle and ligament tissues, thereby alleviating postoperative pain, with a recurrence rate of less than 1%.

Comparatively, TFR seems to be a better option with a lower recurrence rate.
Why wasn't it used for me? I'm almost 22 years old! Shouldn't the fascia be reinforced? This seems to imply a high recurrence rate! I don't want to undergo another surgery unnecessarily...
The doctor initially mentioned that he would use TFR, so why wasn't it done? I really want to know...
Did he deceive me?
Thank you for your response.
Best regards.

Hello, sir: Thank you for your inquiry.
I would like to respond to your question and provide the following suggestions: Regarding whether to use a "prosthetic mesh" for hernia repair surgery, there is still ongoing debate in the surgical community.
The factors of contention are as follows: 1.
The main advantage of using "prosthetic mesh" is that it generally results in less postoperative pain.
2.
However, since "prosthetic mesh" is a foreign material, the risk of infection may be higher.
3.
As for recurrence rates, some literature suggests that the recurrence rate is slightly lower with the use of a composite mesh, but the recurrence rate after surgery is also related to the surgical technique.
Additionally, to be honest, once a patient experiences a recurrence, they may seek treatment from other physicians, making it quite difficult to statistically determine the accuracy of using prosthetic mesh.
Based on my personal clinical experience, the outcomes of both approaches are quite similar.
Furthermore, using a "composite" "prosthetic mesh" can be quite costly.
I recommend that if you have any doubts, you should discuss them with your attending surgeon.
Finally, I wish you peace and happiness!

Dear Patient,
Thank you for your detailed inquiry regarding your recent inguinal hernia repair surgery. I understand your concerns about the surgical technique used and the potential for recurrence, especially given your age and the nature of your condition. Let’s address your questions systematically.


Question 1: Why do young individuals develop inguinal hernias?
Inguinal hernias can occur in individuals of all ages, including young adults. While it is true that the majority of cases are seen in children and older men, several factors can contribute to the development of a hernia in a younger person. These include:
1. Congenital Weakness: Some individuals may have a congenital predisposition to hernias due to a weakness in the abdominal wall that may not have been apparent until later in life. This can manifest as a hernia during activities that increase intra-abdominal pressure, such as heavy lifting, straining during bowel movements, or even during physical activities like sit-ups.

2. Increased Intra-abdominal Pressure: Activities that significantly increase abdominal pressure, such as heavy lifting, intense exercise, or chronic coughing, can lead to the development of a hernia. You mentioned activities like sit-ups and other exercises, which could have contributed to the increased pressure in your abdomen.

3. Obesity or Rapid Weight Changes: Although you did not mention this, being overweight or experiencing rapid weight fluctuations can also increase the risk of developing a hernia.


Question 2: Why was tension-free repair (TFR) not used in your surgery?
Tension-free repair (TFR) is indeed a widely accepted method for hernia repair due to its lower recurrence rates and reduced postoperative pain. However, the decision to use TFR or a traditional method depends on several factors:
1. Hernia Size and Type: In your case, the surgeon may have assessed that your hernia was not large enough or that the tissue quality was sufficient to allow for a traditional repair without the need for mesh. If the hernia sac was small and the surrounding tissue was healthy, a tension-based repair could be deemed adequate.

2. Surgeon’s Judgment: Surgeons often rely on their clinical judgment and experience when deciding on the surgical approach. If your surgeon felt confident that a traditional repair would suffice, they may have opted for that method based on their assessment of your specific situation.

3. Patient Factors: Your overall health, activity level, and personal preferences may also influence the surgical approach. If you were not exhibiting any significant risk factors for recurrence, the surgeon might have chosen a less invasive method.

4. Time Constraints: As you noted, the surgery was completed in under 30 minutes. This could indicate that the procedure was straightforward, and the surgeon felt that a tension-free approach was unnecessary.


Concerns About Recurrence
It is natural to be concerned about the potential for recurrence, especially after undergoing surgery. While traditional methods have a higher recurrence rate (10-15%), many factors contribute to the success of hernia repairs, including the surgeon's skill, the patient's adherence to postoperative care, and lifestyle factors.


Conclusion
In summary, while tension-free repair is an effective method for hernia repair, your surgeon may have determined that a traditional repair was appropriate for your specific case. It is essential to maintain open communication with your healthcare provider about your concerns and to follow their postoperative instructions carefully. If you continue to have concerns about recurrence or your recovery, I encourage you to discuss these with your surgeon or seek a second opinion for peace of mind.

Best regards, and wishing you a smooth recovery.
