Abstract
Liver is the largest solid abdominal organ, has fixed position, partially protected by ribs and has extraordinary regeneration capacity (Michael J. and
Miles J., 1990). It has double vascular blood supply (hepatic artery and
portal vein). Its vascular blood flow was 1.5 L/min (Cox, et .al, 1988).
Liver trauma is common following blunt abdominal trauma and penetrating trauma to the right upper quadrant of the abdomen (Polanco P. ET .al, 2008).
Patients with liver injuries caused by penetrating or blunt abdominal trauma are often encountered in the emergency service of a large hospital. Most such
lesions can be managed by hepatic suture and drainage of the peritoneal cavity with few complications and low mortality (Girgin S. et .al, 2006).Major hepatic resection as a means of management of sever trauma of the liver deserves more serious considerations than it has received in the past. from several reviews in recent years it is apparent that less
aggressive means of management are associated with significant morbidity and high mortality (Cox, et .al, 1988). Indications for resection are straightforward despite inability to decide on procedure prior to operation.
Major resection should be considered for any extensive wound of the liver or one in which bleeding can not be controlled by suture (Safi F. et .al, 1999). In regard to fatal complications of hepatic resection for trauma, two major factors are: (1) other visceral injuries and (2) tears in the hepatic veins or vena cava (Polanco P. et .al, 2008). This study included casualities with major liver trauma that underwent segment-based (anatomical) liver
resection at the department of General Surgery.
