Exploratory laparotomy
Encyclopedia
An exploratory laparotomy (ex-lap) is the standard of care in various blunt and penetrating trauma situations in which there may be multiple life-threatening injuries, and in many diagnostic situations in which the operation is undertaken in search of a unifying cause for multiple signs and symptoms of disease.

The trauma ex-lap is the most comprehensive ex-lap, usually undertaken after evidence of internal bleeding (a positive FAST
