Exploratory Laparotomy

Exploratory laparotomy

An exploratory laparotomy is a surgical process where the abdomen is opened and the abdominal organs examined for injury or examined for disease. It 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 multiple symptoms of disease.

Indications and procedure

The trauma ex-lap is the most comprehensive ex-lap, usually undertaken after evidence of internal bleeding. A midline incision is carried down towards the linea alba and the fascia is incised. The peritoneum is entered and any immediate, life-threatening bleeding is identified and also controlled. The lateral, superior, and anterior surfaces of the liver are packed with sponges, and also the superior and lateral spaces around the spleen are similarly packed.

The alimentary canal is run from the ligament of Treitz to the terminal ileum. The gastrocolic ligament is incised and the lesser sac is explored, including the posterior stomach and the anterior pancreas. The surface of the abdominal organ is examined for an evidence of laceration and fracture.

The liver is similarly examined. If necessary, Cattell and Mattox maneuvers may be performed to expose retroperitoneal structures. If the duodenum is at risk, a Kocher maneuver may be performed to examine the posterior duodenum and the head of the pancreas.
