Inguinal hernia repair surgery is a surgical procedure used to treat inguinal hernias. Its primary goal is to reposition protruding intra-abdominal tissues and repair the abdominal wall defect to prevent recurrence. This surgery is suitable for patients of all ages, including adults and children, especially when the hernia causes pain, bowel strangulation, or interferes with daily activities. The procedure can be performed as an open surgery or laparoscopically, with the choice depending on the patient's age, hernia type, and overall health status.
Open hernia repair (Open Hernia Repair) involves making an incision in the groin area to directly suture or remove the hernial sac, often reinforced with a synthetic mesh to strengthen the abdominal wall. This method is suitable for unilateral or recurrent hernias, with a surgical duration of approximately 1 to 2 hours. Laparoscopic surgery (Laparoscopic Surgery) involves inserting 3 to 4 small incisions to introduce a camera and instruments, allowing visualization-guided tissue repair. This approach results in smaller scars and faster recovery but requires the patient to tolerate general anesthesia.
The use of mesh is a key technique, with materials such as polyester or polytetrafluoroethylene providing permanent reinforcement to weak areas of the abdominal wall, thereby reducing the risk of recurrence. The mechanism involves reconstructing the anatomical structure to prevent the intestine or fat tissue from protruding again, while also reducing postoperative pain and tissue adhesions.
This procedure is primarily indicated for all diagnosed inguinal hernia patients, including those with intermittent or persistent swelling, or pain that worsens when standing or straining. Emergency cases such as hernia strangulation or bowel obstruction require immediate surgery to prevent tissue necrosis. Congenital hernias in children over 1 year old that do not resolve spontaneously or that recur and cause complications also require surgical intervention.
The surgery is also suitable for patients who do not respond to conservative treatments, such as those who cannot control symptoms with a hernia belt, or for workers engaged in strenuous activities requiring long-term abdominal support. Recurrent or bilateral hernias are also best treated with surgery as the definitive solution.
The procedure is usually performed under general anesthesia, with hospitalization duration varying by surgical type: day surgeries may allow discharge on the same day, while complex cases may require 2-3 days of hospitalization. Preoperative assessments include blood tests, cardiopulmonary evaluation, and anesthesia consultation. Female patients should confirm pregnancy status. Immediately after surgery, a pressure dressing is applied to protect the wound, and pain medications and activity restrictions are prescribed according to the physician’s instructions.
The choice of mesh depends on the patient’s age and hernia type; adults typically receive permanent meshes, while children may use absorbable materials. The surgery duration is approximately 1 to 2 hours, potentially extending to 3 hours in complex cases. Recovery generally takes 2 to 4 weeks, during which lifting heavy objects and strenuous activities should be avoided.
Main advantages include:
The surgery can immediately address chronic pain and lifestyle limitations caused by the hernia, especially benefiting patients engaged in physically demanding occupations by restoring normal activity levels. Bilateral hernias can be treated in a single operation, reducing the need for multiple surgeries.
Potential short-term risks include:
Long-term risks include:
Emergency Notice: If postoperative fever, redness, swelling at the wound site, or difficulty in bowel movements occur, seek medical attention immediately.
Preoperative assessment should include a review of all chronic illnesses (such as diabetes, coagulopathies), and anticoagulant medications (like aspirin) should be discontinued. Postoperative activity restrictions must be strictly followed, avoiding lifting heavy objects for at least 4 to 6 weeks. Contraindications include:
Pregnant women or those who recently underwent abdominal surgery should have their surgical plan adjusted. Patients with severe liver or kidney dysfunction may need to opt for non-mesh repair methods.
Patients on anticoagulant therapy (such as warfarin) should stop medication 7 days before surgery and switch to low-molecular-weight heparin bridging. Postoperative pain management should avoid NSAIDs, as they may delay wound healing. Patients undergoing chemotherapy or immunosuppressive therapy should adjust medication doses and enhance infection prevention measures.
Timing of other abdominal surgeries should be spaced at least 6 weeks apart to allow proper tissue healing. Diabetic patients should maintain strict blood glucose control to reduce infection risk.
Large randomized controlled trials show that mesh repair has a recurrence rate below 2% over five years, significantly lower than the 10-15% seen with traditional suturing. Laparoscopic patients typically have shorter hospital stays (0.5-1 day vs 2-3 days) and report 30-40% less pain. Long-term follow-up indicates that patients with non-absorbable mesh have similar 10-year survival rates compared to non-surgical groups, demonstrating high safety. Pediatric patients undergoing mesh repair have a 95% complete recovery rate without long-term complications. Elderly patients receiving minimally invasive surgery experience a 60% improvement in quality of life, highlighting its clinical benefits.
Non-surgical treatments are limited to high-risk elderly patients, using hernia trusses temporarily to relieve symptoms but do not cure the hernia and may cause tissue damage. Observation is suitable for small, asymptomatic hernias with follow-up every 3-6 months. Pharmacological treatments currently lack evidence for hernia repair and are only used for postoperative pain management. Therefore, surgery remains the only definitive treatment, especially when symptoms impair quality of life.
What preparations are necessary before surgery to ensure a smooth inguinal hernia repair?
Patients should undergo physical examinations, blood tests, and imaging assessments preoperatively to evaluate surgical risks. Fasting for 12 hours before surgery is required, and any medications being taken should be disclosed; some, like anticoagulants, may need dose adjustments. Quitting smoking several weeks before surgery can reduce infection risk.
How can pain and swelling be alleviated after surgery? What are safe pain management methods?
Initial postoperative discomfort may include mild pain and swelling. Physicians typically prescribe analgesics such as NSAIDs to relieve discomfort. Applying ice packs (15-20 minutes per session) can reduce swelling but should avoid direct skin contact to prevent frostbite. If pain worsens or fever develops, seek medical attention promptly.
When can normal activities be resumed? When is it safe to return to strenuous exercise?
Light activities like walking can usually begin 1-2 days after surgery, but lifting heavy objects should be avoided for at least 2-4 weeks. More intense exercises, such as weightlifting or sports, should generally wait for over 6 weeks, depending on the surgical method and individual recovery. Follow-up with the physician will guide the appropriate timeline.
What is the recurrence rate after surgery? How can recurrence be minimized?
The modern surgical techniques have reduced recurrence rates to below 5%. Factors such as obesity, chronic cough, or straining during bowel movements can increase risk. Maintaining a healthy weight, strengthening core muscles, and avoiding behaviors that increase intra-abdominal pressure are recommended. Regular check-ups can help detect early signs of recurrence.
Is the use of synthetic mesh safe? Are there long-term complications?
Artificial meshes are the current standard material for hernia repair, with high biocompatibility and long-term support for tissues, reducing recurrence rates compared to traditional suturing. Rarely, patients may experience mesh rejection or infection, with an incidence below 1%. Long-term follow-up studies show that meshes provide stable support for the abdominal wall without significant long-term complications.
