Damage Control Laparotomy
On this page
Direct answer
Pack, stop the bleeding, control contamination, close temporarily, and leave — the abbreviated laparotomy that accepts an uncompleted operation in exchange for a living patient is damage control surgery, and its trigger is physiology rather than anatomy: hypothermia below 34–35 degrees C, acidosis with pH under about 7.2, coagulopathy with diffuse ooze, massive transfusion requirements (commonly over 10 units), or an inability to close the abdomen without tension. The classical sequence runs in phases: the abbreviated operation, then 24–48 hours of intensive-care resuscitation correcting the lethal triad, then planned re-operation for definitive repair and staged closure — accepting complications such as enteroatmospheric fistula, planned ventral hernia and abdominal compartment syndrome as the price of survival.
What you must remember
- Indications (physiological): the "triad of death" — core temperature below 34–35 degrees C, pH under about 7.2, and clinical coagulopathy; transfusion exceeding about 10 units; combined major vascular and visceral injuries needing time; inability to achieve haemostasis; abdominal compartment syndrome; and mass casualty or resource constraints (the concept's wartime origin).
- Phase 1 (minutes, theatre): control haemorrhage by packing (liver, pelvis, retroperitoneum), ligation or temporary intravascular shunting; control contamination by stapling or ligating bowel without anastomosis; temporary abdominal closure.
- Phase 2 (24–48 hours, ICU): rewarming, correction of coagulopathy with products guided by ROTEM/TEG, ventilation, bladder-pressure surveillance, and re-examination of the decision.
- Phase 3 (planned re-operation): pack removal, definitive repair or anastomosis, bowel continuity, and abdominal closure — possibly staged over returns at 24–48 hour intervals ("planned re-laparotomy") versus on-demand reoperation guided by physiology.
- Temporary closure options: vacuum-assisted negative-pressure dressing (the modern standard), Bogota bag (sterile plastic sewn to fascia), Wittmann patch (velcro-like fascial sheets), and skin-only closure or towels.
- Complications: enteroatmospheric fistula (the feared one — bowel exposed to the open wound), abdominal compartment syndrome, fascial retraction forcing a planned ventral hernia repaired months later, deep infection, and massive fluid losses.
- The terminology to deploy in a viva: "damage control" borrows from the navy — stop the sinking, defer the refit.
How to work through it
A 26-year-old with a gunshot injury to the abdomen arrives with a systolic of 70 and has already received 8 units of blood. Laparotomy finds a torn iliac vein, two jejunal perforations, and a liver laceration oozing diffusely. Forty minutes in, his temperature is 34 degrees C, pH 7.15, and the field is weeping from every puncture — the decision to stop is itself the skill. Phase 1 executed: the vein is shunted or ligated, the jejunum is stapled closed and left in discontinuity, the liver is packed with laparotomy pads against the diaphragm, and the abdomen is closed with a negative-pressure temporary dressing. Total theatre time under 90 minutes. Phase 2 in ICU: forced-air rewarming, warmed humidified ventilation, products by viscoelastic guidance, calcium replacement, and bladder-pressure monitoring. At 36 hours, rewarmed and corrected, he returns to theatre: packs out (removed carefully to avoid tearing capsular clots), bowel continuity restored with resection and anastomosis now safe, the vein repaired, and the abdomen closed — primarily if tension-free, otherwise staged. If instead his bladder pressure had climbed to 25 mmHg with oliguria in the ICU, the response would be reopening at once, since temporary closure trades one catastrophe (death) for a manageable one (open abdomen).
Where students slip
The cardinal error is treating damage control as a technique for pitiful situations rather than a decision with a trigger — the examiner asks "when would you decide", and the winning answer names the physiological thresholds at which completion of the operation becomes more dangerous than stopping. The second error is Phase 1 scope creep: performing an anastomosis, a pancreatic resection or a formal repair in a dying patient; the correct Phase 1 inventory is short — pack, ligate, shunt, staple, drain, close temporarily. The third is terminology: confusing the Bogota bag, Wittmann patch and vacuum dressings, or writing "close the abdomen fully to prevent infection" when forced closure under tension is precisely what produces abdominal compartment syndrome. Finally, the fistula point: candidates describe the open abdomen without mentioning enteroatmospheric fistula as its signature complication and the reason visceral protection (negative-pressure systems with non-adherent layers) matters.
Frequently asked questions
What physiological parameters trigger damage control surgery?
Core temperature below about 34–35 degrees C, pH under about 7.2, clinical coagulopathy with non-surgical bleeding, or transfusion in the region of 10 units — the point at which anatomy yields to physiology.
What is achieved in the abbreviated first operation?
Haemorrhage control by packing, ligation or temporary shunting; contamination control by stapling or ligating bowel without anastomosis; and temporary abdominal closure — nothing elective.
Why is an anastomosis avoided during damage control?
Because a cold, acidotic, coagulopathic, massively transfused patient has splanchnic hypoperfusion and impaired healing, so anastomotic failure rates are unacceptable; continuity is restored at re-operation once physiology is corrected.
What are the temporary abdominal closure options?
Vacuum-assisted negative-pressure dressings (current standard), the Bogota bag sewn to fascia, Wittmann velcro patches, skin-only closure, or saline-soaked towels — all trading closure for perfusion.
What is the feared late complication of the open abdomen?
Enteroatmospheric fistula — exposed bowel eroding into the wound — along with failure of fascial closure requiring planned ventral hernia; both drive the strategy of earliest safe definitive closure.
