The PDF is ready. Here is a summary of everything covered, followed by your download link.
Mesh in Hernia Repair - Summary
Content was sourced from Bailey & Love's Surgery 28e, Sabiston Surgery 21e, Fischer's Mastery of Surgery 8e, Mulholland & Greenfield's Surgery 7e, and Current Surgical Therapy 14e.
What the PDF Covers
Section 1 - What is Mesh?
Three uses: bridging a defect, plugging a defect (largely abandoned), and augmenting a suture repair (current standard). Inlay repair (edge-to-edge, no overlap) is explicitly not recommended.
Section 2 - Mesh Classification
- Synthetic (PP, Polyester, PTFE): Polypropylene is hydrophobic, inert, and infection-resistant. Polyester is hydrophilic, encourages microvascular ingrowth but multifilament structure is infection-intolerant. PTFE is the best adhesion barrier but cannot withstand infection.
- Biological mesh: Decellularised human/animal dermis, bovine pericardium, or porcine submucosa - provides a scaffold; expensive; recurrence up to 21%.
- Absorbable/biosynthetic: Rapid absorbers not suitable for hernia repair; slowly absorbing biosynthetics are preferred in contaminated fields.
Section 3 - Mesh Properties
- Pore size: Large-pore (≥1,000 µm) preferred - better integration, less contracture, better infection tolerance
- Weight/density: Lightweight (35-50 g/m²) to mid-weight preferred; heavyweight = strongest but worst infection tolerance
- Filament structure: Monofilament large-pore PP best tolerates infection; multifilament and microporous PTFE must be removed if infected
- Mesh contracture: Can reduce coverage area >50% - always plan generous overlap
- Barrier coatings: No coating is 100% effective against adhesions
Section 4 - Mesh Positioning: Onlay / Inlay (not recommended) / Sublay / Extraperitoneal / Intraperitoneal (avoid when possible)
Section 5 - Hernia-Specific Applications:
| Hernia | Preferred Mesh | Position |
|---|---|---|
| Inguinal - Lichtenstein | Lightweight PP (8×15 cm) | Posterior wall / preperitoneal |
| Inguinal - TEP/TAPP | Lightweight PP (≥10×15 cm) | Extraperitoneal |
| Incisional - Rives-Stoppa | Mid-weight PP | Sublay/retromuscular |
| Incisional - IPOM | Composite anti-adhesive | Intraperitoneal |
| Parastomal | Composite/PP | IP or sublay |
| Hiatal/paraesophageal | Biologic | Hiatal reinforcement |
| Contaminated/bowel resection | Biologic or biosynthetic | As required |
| Open abdomen (bridging) | Biologic or biosynthetic | Bridging |
Sections 6-8: Quick-reference summary table, complications (infection, chronic pain, seroma, adhesions, erosion, recurrence, meshoma), and 12 key practice points.
