SOC → SCF-DBI Logic Translation
Purpose
Temporary Abdominal Closure (TAC) is a damage-control surgical strategy used when definitive fascial closure would place the patient at risk of physiologic deterioration, abdominal compartment syndrome, recurrent bleeding, bowel edema, or ongoing contamination.
TAC creates a controlled biologic bridge between Damage-Control Surgery and Definitive Reconstruction.
SOC Definition
Primary Objectives
Prevent Abdominal Compartment Syndrome
Avoid excessive intra-abdominal pressure caused by:
- Visceral edema
- Ongoing resuscitation
- Hemorrhage
- Packing
Facilitate Re-exploration
Allow rapid return to the operating room for:
- Second-look laparotomy
- Reassessment of bowel viability
- Additional hemorrhage control
- Definitive reconstruction
Manage Ongoing Contamination
Provide temporary control while:
- Inflammation decreases
- Physiology improves
- Source control matures
SCF-DBI Translation
Core Concept
SOC views TAC as:
A temporary physical abdominal closure.
SCF-DBI views TAC as:
Creation of a Controlled Regenerative Recovery Environment (CRRE).
The TAC becomes an active biologic interface that continuously influences:
- Tissue viability
- Perfusion
- Inflammation
- Microbial burden
- Fascial recovery
- Reconstruction readiness
