Emergency Laparotomy
On this page
Direct answer
In Indian emergency theatres the perforated peptic ulcer remains the commonest reason for an urgent laparotomy, followed by typhoid and tubercular ileal perforations and strangulated hernias — a spectrum quite different from Western diverticular and trauma lists. Whatever the cause, physiology decides strategy: a patient cooling, acidotic and coagulopathic — the lethal triad — is not a candidate for definitive repair but for damage control surgery, an abbreviated laparotomy to stop bleeding and control contamination, temporary abdominal closure, ICU resuscitation for 24–48 hours, and a planned relaparotomy. Source control within hours, broad-spectrum antibiotics and honest anastomosis-versus-stoma decisions in a contaminated abdomen matter more than any single technique.
What you must remember
- The lethal triad — hypothermia (core under 35°C), metabolic acidosis (pH under 7.2) and coagulopathy — is self-amplifying; recognising it shifts the plan to damage control.
- Damage control stages: abbreviated laparotomy (packing, stapling off bowel without anastomosis), temporary closure, ICU correction, planned relaparotomy in 24–48 hours, delayed closure.
- Temporary abdominal closure: Bogotá bag, Wittmann patch or negative-pressure wound therapy; lactate clearance guides the return to theatre.
- Perforated duodenal ulcer: simple closure with an omental (Graham) patch is the default in India; giant perforations over 2–3 cm need pedicled tissue or Roux-en-Y duodenojejunostomy; H. pylori eradication follows.
- Typhoid perforation: typically a single ileal perforation within 30–60 cm of the ileocaecal junction in the second to third week of fever; primary two-layer closure for small perforations, resection-anastomosis for multiple, a stoma when the patient is poor — Indian series report meaningful mortality, so operate early.
- Abdominal tuberculosis perforates through diseased ileocaecal segments; the surgeon balances resection with primary anastomosis against a protective stoma, and anti-tubercular therapy follows.
- Free subdiaphragmatic gas on an erect film confirms perforation but is absent in up to a quarter to a third of cases — a normal film never excludes one; CT with contrast is more sensitive.
- The Mannheim Peritonitis Index stratifies risk (above about 30, high mortality); UK NELA audit data put 30-day mortality around 10–15 per cent, warranting vascular-surgery seniority.
How to run a damage control laparotomy
A 45-year-old man arrives after a road accident with a rigid abdomen, blood pressure 80 systolic after two litres of fluid, and free fluid on bedside ultrasound. The sequence is choreographed. First, resuscitation: blood products in balanced ratio, tranexamic acid within three hours, active warming from the first minute — every degree of hypothermia deepens the coagulopathy. Second, the abbreviated laparotomy: midline incision, rapid packing of all four quadrants, gross bleeding controlled by clamping; hollow viscus injuries are stapled across without anastomosis, and contamination sucked out. Third, temporary closure with a negative-pressure dressing — the visceral oedema of resuscitation will not tolerate primary closure without abdominal compartment syndrome. Fourth, the ICU phase: rewarming, correction of acidosis and coagulopathy, lactate trended, and the return to theatre in 24–48 hours booked at the first operation. Fifth, the relaparotomy: packs out, missed injuries sought, definitive repair or stoma performed, and closure direct, with mesh, or with a planned hernia for later repair. The candidate who says "the first operation is measured in tens of minutes" understands damage control.
Where students slip
The trap is the endless resuscitation: peritonitis "being optimised" for six hours while the septic source remains uncontrolled. Resuscitation runs in parallel, and source control within the first hours is itself part of the resuscitation. The second slip is technical pride: a primary ileal anastomosis in a malnourished typhoid patient with a feculent abdomen, when a stoma is safer — the humility to choose it and say why is what is being tested.
Frequently asked questions
What triggers conversion to a damage control strategy?
The lethal triad — hypothermia under 35°C, pH under 7.2, coagulopathy — with major ongoing bleeding or contamination; the operation is abbreviated in favour of physiological rescue in intensive care.
How is a perforated duodenal ulcer managed surgically?
Simple closure with a Graham omental patch and thorough peritoneal lavage, with H. pylori eradication and proton pump inhibition afterwards; giant or hostile perforations need pedicled jejunal tissue or a Roux-en-Y duodenojejunostomy.
What characterises typhoid ileal perforation?
A single antimesenteric perforation within roughly 30–60 cm of the ileocaecal junction in the second or third week of enteric fever; primary two-layer closure for small perforations, resection-anastomosis for multiple, stomas for desperately ill patients.
Why can a normal erect radiograph not exclude perforation?
Free gas is absent in up to about a quarter to a third of perforations, especially small or sealed ones; persistent clinical peritonitis demands CT with contrast or diagnostic laparoscopy.
What is temporary abdominal closure and why leave the abdomen open?
A Bogotá bag, Wittmann patch or negative-pressure dressing over the viscera, preventing abdominal compartment syndrome from visceral oedema while allowing planned relaparotomy.
How good are outcomes after emergency laparotomy?
Thirty-day mortality in audit data runs about 10–15 per cent — comparable to major cardiac surgery — demanding senior input and early theatre; Indian series confirm late presentation as the dominant mortality driver.
