Abdominal Wall Reconstruction Techniques

Primary Closure and Component Separation

Primary fascial closure is the ideal solution to restore abdominal closure when feasible, according to the World Journal of Emergency Surgery guidelines 1, 2
Component separation is an effective technique that should be considered only for definitive closure, not temporary closure, as recommended by the World Journal of Emergency Surgery 1, 2

For clean surgical fields, synthetic mesh is recommended for hernia repair, according to Praxis Medical Insights 3
Non-cross-linked biologic meshes are preferred in sublay position when the linea alba can be reconstructed, as suggested by the World Journal of Emergency Surgery 1, 2
Cross-linked biologic meshes in fascial-bridge position may be associated with less ventral hernia recurrence when linea alba closure is not possible, according to the World Journal of Emergency Surgery 1, 2
Synthetic meshes in contaminated fields are not recommended in emergency abdominal wall reconstruction, as stated by the World Journal of Emergency Surgery 1, 2

Use continuous suture technique for fascial closure as it is faster than interrupted sutures with no difference in hernia or dehiscence rates, according to Praxis Medical Insights 3
Maintain a suture-to-wound length ratio of at least 4:1 for continuous closure, as recommended by Praxis Medical Insights 3
Use small bite technique to prevent incisional hernia and wound complications, according to Praxis Medical Insights 3
Employ mass closure rather than layered closure for speed and equivalent outcomes, as suggested by Praxis Medical Insights 3

Never use synthetic mesh as a fascial bridge in contaminated fields—this induces adhesions, erosions, and fistula formation, as warned by the World Journal of Emergency Surgery 1, 2
Do not use component separation for temporary closure—reserve it for definitive reconstruction only, according to the World Journal of Emergency Surgery 1, 2
Planned ventral hernia remains an option for the complicated open abdomen in the presence of entero-atmospheric fistula or protracted open abdomen where no other alternatives are viable, as stated by the World Journal of Emergency Surgery 1, 2
