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 of technique depending on the patient's age, hernia type, and overall health status.
Open hernia repair involves making an incision in the groin area to directly suture or remove the hernia sac, often reinforced with a synthetic mesh to strengthen the abdominal wall. This approach is suitable for unilateral or recurrent hernias, with a typical duration of 1 to 2 hours. Laparoscopic surgery involves inserting 3 to 4 small incisions to introduce a camera and surgical instruments under video guidance, resulting in smaller scars and faster recovery, but requires general anesthesia and patient suitability.
The use of mesh is a critical technique, with materials such as polyester or polytetrafluoroethylene providing permanent reinforcement to weak abdominal walls and reducing recurrence rates. The mechanism involves reconstructing the anatomical structure to prevent the intestine or fat tissue from protruding again, thereby reducing postoperative pain and tissue adhesions.
This procedure is mainly indicated for all diagnosed inguinal hernia patients, including those with intermittent or persistent swelling, and 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 necessitate surgical intervention.
The surgery is also suitable for patients who do not respond to conservative treatments, such as those unable to control symptoms with hernia belts, or workers engaged in heavy physical labor 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 the type of surgery: day surgery patients may be discharged the same day, while complex cases may require 2-3 days of hospitalization. Preoperative assessments include blood tests, cardiopulmonary evaluation, and anesthesia assessment; women should confirm pregnancy status. Immediately after surgery, a pressure dressing is applied to protect the wound, and pain medications and activity restrictions are prescribed as per medical advice.
The choice of mesh depends on the patient's age and hernia type; adults typically receive permanent mesh, while children may use absorbable materials. The operation lasts approximately 1 to 2 hours, but complex cases may extend to 3 hours. Recovery typically takes 2 to 4 weeks, during which lifting heavy objects and strenuous activities should be avoided.
Main advantages include:
The surgery can immediately relieve chronic pain and lifestyle limitations caused by the hernia, especially for patients engaged in physically demanding work, enabling a return to normal activities. Patients with 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 high fever, redness, swelling at the wound site, or difficulty in bowel movements occur postoperatively, seek medical attention immediately.
Preoperative assessment should include detailed medical history (such as diabetes, coagulation disorders), and discontinuation of anticoagulants (e.g., aspirin). 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 plans adjusted. Patients with severe liver or kidney dysfunction may opt for non-mesh procedures.
Patients on anticoagulant therapy (e.g., warfarin) should stop medication 7 days before surgery and switch to low-molecular-weight heparin bridging therapy. Postoperative pain management should avoid NSAIDs, which 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 ensure proper tissue healing. Diabetic patients should strictly control blood glucose levels to reduce infection risk.
Large randomized controlled trials show that mesh repair has a 5-year recurrence rate below 2%, significantly lower than traditional suturing (10-15%). Laparoscopic patients 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 a 10-year survival rate comparable to non-surgical groups, demonstrating high safety. Pediatric patients undergoing mesh repair have a 95% full recovery rate without long-term complications. Elderly patients receiving minimally invasive surgery report a 60% improvement in quality of life, indicating substantial clinical benefits.
Non-surgical treatments are limited to high-risk elderly patients, using hernia trusses temporarily to alleviate symptoms but do not cure the hernia and may cause tissue damage. Observation is suitable for small, asymptomatic hernias with regular 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 studies to assess surgical risks. Fasting for 12 hours before surgery is required, and medications should be disclosed to the doctor; some drugs (like anticoagulants) may need adjustment. Quitting smoking several weeks prior can reduce infection risk.
How can pain and swelling be alleviated after surgery? What are safe pain relief methods?
Postoperative mild pain and swelling are common; doctors may prescribe analgesics such as NSAIDs. Applying ice packs (15-20 minutes per session) can reduce swelling, but direct skin contact should be avoided to prevent frostbite. If pain worsens or fever occurs, seek medical attention promptly.
When can normal activities resume? When is it safe to return to strenuous exercise?
Light activities like walking can usually start 1-2 days after surgery, but lifting heavy objects should be avoided for at least 2-4 weeks. More intense exercises (weight training, sports) should wait over 6 weeks, depending on the surgical approach and individual recovery. The doctor will provide tailored advice based on recovery progress.
What is the recurrence rate after surgery? How can recurrence be minimized?
The modern surgical techniques have a recurrence rate 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 activities that increase intra-abdominal pressure are recommended. Regular follow-up examinations help detect early signs of recurrence.
Is using artificial mesh for hernia repair safe? Are there long-term complications?
Artificial mesh is the current standard material for hernia repair, with high biocompatibility and long-term support, reducing recurrence rates compared to traditional suturing. Rarely, patients may experience mesh rejection or infection, with an incidence below 1%. Long-term studies show that mesh provides stable support for the abdominal wall without significant long-term complications.
