Diaphragmatic Hernia Mesh Repair

Diaphragmatic hernia mesh repair

The diaphragmatic hernia mesh repair is the operation done on an individual with a diaphragmatic hernia but the defect in the diaphragm is too large to be closed with sutures alone. Mesh reinforcement provides additional support, lessens tension on the repair, and reduces the risk of recidivism — also in large or recurrent hernias, traumatic diaphragmatic ruptures, and, in select instances, of congenital diaphragmatic hernia (CDH). 

Indications

When to use mesh

• The defect in the musc1e of the diaphragm is large or tense.
• Primary closure too weak.
• There is recurrent diaphragmatic hernia.
• Traumatic or iatrogenic defects are shaggy.
• Poor or thinned tissue quality.

Types of Mesh Used

Synthetic Mesh

• Pros: Strong, durable, low recurrence.
• Cons: Potential for adhesions and infection.

Biologic Mesh

• Advantages: Reduced risk of infection, tissue ingrowth.
• Disadvantages: high costs, potentially loses strength over time.

Composite Mesh

• Combination of synthetic strength and anti-adhesive coating.
• Recommended for repairs near abdominal organs.

Benefits of Mesh Repair

• Robust, tensionless closure.
• Decreased rates of recurrence.
• Enables the repair of large or irregular defects.
• Improved long-term structural support.

Mesh repair diaphragmatic hernia

Mesh repair is done] is the method of choice when the diaphragmatic defect is too large, too tense, or otherwise deemed unsafe to be closed by sutures alone. The mesh reinforces the repair and adds strength and stability to the abdominal wall, and also decreases the chance of hernia recurrence. 

Approaches for Mesh Repair

Open Repair

• Employed for extensive ruptures.
• Provides excellent exposure and good fixation of mesh.

Laparoscopic Mesh Repair

• Minimally invasive.
• Mesh tacked or sewn (sometimes with both methods).
• Better recovery and less pain.

Thoracoscopic Mesh Repair

• The procedure is done when the defect is more readily approached through the chest.
• Mesh contributes to the thoracic surface of the diaphragm.

Surgical Techniques for Mesh Placement

Onlay Mesh Placement

• Mesh is placed on the repaired diaphragm.
• Common in open surgery.

Underlay (Inlay) Repair

• Mesh positioned under the hernia defect or as a bridge.
• Frequently used in laparoscopic repair.

Sandwich Technique

• Employs mesh at both sides of the diaphragm for sizable leaks.

Procedure Steps

• ACCESS METHODS: Open, laparoscopy or thoracoscopy.
• Herniated contents in the abdomen reduction.
• Measurement of defect size and tension.
• Edges of primary suturing when possible.
• Insertion of mesh (specific type selected).
• Strong attachment using non-absorbable sutures or tackers.
• Checking for a tight and tension free sealing.
• Closure

Recovery

• Length of stay at hospital: 2–5 days (may depend on method, severity).
• Light activities: When1-2 weeks.
• Strenuous exercise: Wait for 6 – 8 weeks.
• The recurrence following mesh repair is low as opposed to after primary repair.

Laparoscopic diaphragmatic hernia mesh repair

Laparoscopic diaphragmatic hernia mesh repair is a type of minimally invasive operation for repairing diaphragmatic defects through several small incisions using a camera and specialized equipment. Mesh placement is utilized when the defect is large, is under tension, or is unsuitable for primary suturing, providing long-term strength and decreased recurrence.

Types of Mesh Used

The most preferred type is Composite Mesh.

• One side has a coating that prevents adhesion.
• Prevents intestines from adhering to the mesh.
• Best utilised in the abdomen.

PTFE Mesh

• Smooth surface→minimal adhesions
• Strong and durable

Polypropylene Mesh

• Very strong
• Adhesion risk when used without a barrier to protect

Biologic Mesh

• Employed in contaminated surgery
• Less strong but integrates naturally (less strong)

Laparoscopic Procedure Steps

• Anaesthesia – General anaesthesia, with controlled ventilation.
• Port placement – The usual number of port is 3-4.
• Pneumoperitoneum - Carbon dioxide is insufflated to create working space.
• Reduction of hernia contents: stomach, liver, colon, or bowel is returned to the abdomen.
• Defect assessment – Measurement of the size, location, and tension.
• Primary closure (when feasible): Approximation of the defect margins is done using non-absorbable sutures. 

Mesh placement

• Place mesh over or under the defect
• Generally with a 3-5 cm overlap at least
• Composite/anti-adhesive side towards abdominal organs)

Fixing the mesh

• Sutures non – absorbables OR
• Tacks (spiral tackers) or
• Technique all or partially
• Inspection for haemostasis
• Port closure

Postoperative Recovery

• Hospital stay: 1–3 days
• Pain level – Mild to moderate pain, usually well controlled with oral medications
• Diet: Liquid → soft diet → regular as tolerated
• Exercise: Light exercise in 3–5 days
• Do not lift strenuous >10-15 kg for 6-8 weeks
• Follow-up imaging: Occasionally for large mesh repairs
• Work: Off work: 1 to 2 weeks for desk jobs

• Artemis Hospital, Gurgaon
• Medanta-The Medicity, Gurgaon
• Fortis Memorial Research Institute, Gurgaon
• Max Hospital, Saket

Conclusion

Laparoscopic diaphragmatic hernia mesh repair offers a safe and minimal invasive approach for treatment of large or multiple defects in the diaphragm. Benefiting from improved visualization and having the option of mesh reinforcement, the repair is now stronger, without tension, and with a substantially lower risk of recurrence. Compared with open surgery, patients experienced smaller incisions, less pain and faster recovery. With appropriate patient selection and meticulous postoperative care, the laparoscopic mesh repair offers a good long-term results and it still is the technique of choice for the surgical management of the modern day diaphragmatic hernia.

FAQ

When is mesh used in diaphragmatic hernia repair?

• When the defect is too large, under tension or cannot be safely approximated with sutures alone, mesh is used. It makes the repair stronger and less likely to recur.

Is it safe to have a laparoscopic repair with mesh?

• Yes It is considered a safe and effective technique with less pain, faster recovery, and excellent long-term outcomes.

Is mesh left in my body forever?

• Synthetic Mesh is usually left in your body for permanent support. Biologic mesh can be absorbed and become part of the natural tissue over time.

Is the procedure painful?

• It is generally mild to moderate and rapidly improving. Most patients do very well with pain medicines by mouth.

Can a hernia return after mesh repair? 

• Recurrence is very low when mesh is placed correctly, particularly in laparoscopic repairs.

Can all diaphragmatic hernias be repaired laparoscopically?

• Most can, but very large traumatic defects or unstable patients may still require open surgery.
