Damage control surgery and angiography in cases of acute mesenteric ischaemia.

BACKGROUND: Acute mesenteric arterial occlusion typically presents late and has an estimated mortality of 60-80%. This report examines the evolution of a novel management approach to this difficult surgical problem at a teaching hospital in rural Australia.
METHODS: A retrospective review of 20 consecutive cases that presented to Lismore Base Hospital, Lismore, New South Wales, between 1995 and 2003 was performed.
RESULTS: Of the 16 patients who were actively treated, 10 survived. Mortality was associated with attempting an emergency operative revascularisation and not performing a second-look laparotomy. All three patients who had a damage control approach at the initial operation survived and in four cases endovascular intervention successfully achieved reperfusion of acutely ischaemic bowel.
CONCLUSIONS: Evidence from the series of patients described suggests that damage control surgery and early angiography improve survival in patients suffering acute mesenteric ischaemia. A damage control approach involves emergency resection of ischaemic bowel with no attempt to restore gastrointestinal continuity and formation of a laparostomy. Patients are stabilised in the intensive care unit (ICU) and angiography can be arranged to either plan a definitive bypass procedure or alternatively endovascular therapies can be carried out in an attempt to arrest gastrointestinal infarction. Definitive surgery is then considered after 2-3 days. This approach is particularly attractive if immediate specialist vascular expertise is not available.
