What is TORSO :
The body excluding the head and neck and
limbs

The medical problems associated with
physical injury .
Injury is the adverse effect of physical force
upon a person .
Forces that can lead to injury include :
mechanical , thermal ,ionizing radiation , and
chemical .

The Troso is generally regarded as the area
between the neck and the groin ,made up of
the thorax and abdomen .
Division of the body into abdomen and
thorax is artificial .
Injury to the troso is more appropriate.
Our aim is restoration of normal physiology .
Accordingly trauma surgery requires
knowledge of anatomy and physiology .

Between the neck and the thorax .
Between the thorax and the abdomen .
Between the abdomen and the pelvic
structures and the groin .
This zones represent surgical challenges in
terms of diagnosis of the area of injury and
surgical approach .
It is related and balanced against the
physiological stability of the patient .

Patients who have suffered abdominal injury
can be generally classified into :
 Haemodynamiclly normal .
 Haemodinamiclly stable .
 Haemodynamically unstable .

Cardiovascular status .
Radiological imaging .
Stable patient may be able to have CT scan .
Evaluation of torso trauma .

CT scan with intravenous contrast most valuable
( however in unstable patient it not always
possible ) .
 DPL Diagnostic peritoneal lavage .
the presence of > 100 000 red cells /micro liter
or > 500 white cells in the peritoneal washout is
an indication of intraperitoneal bleeding and this
is equivalent to 20 ml of free blood in the
abdominal cavity .
Drainage of peritoneal lavage fluids via chest drain
is an indication of penetration of diaphragm .

When positive it means that there is free
blood in the peritoneal cavity .
Negativity does not rule out the presence of
blood in the peritoneal cavity .

FAST Focused abdominal sonar for trauma .
 FAST is a technique whereby US imaging is used
to assess the TORSO for the presence of blood .
 This technique focuses on four areas :
Pericardial,
Splenic ,
Hepatic ,
Pelvic .
FAST is accurate for the detection of < 100 ml of
free blood in the peritoneom .
It is extremely dependent on the operator
experience .

CT is the gold standered for the intraabdominal diagnosis in the stable patient .
CT is performed using intravenous and often
oral contrast as well .
CT has the advantages of sensitivity for the
diagnosis of retroperitoneal injury .
CT is usually sufficient to exclude injury .

DL is valuable screening investigation in
penetrating trauma .
DL of course in stable patient s following an
abdominal or thoraco-abdominal stab wound .
DL is not appropriate for use in the unstable
patient .
DL is difficult to exclude all intra-abdominal
injuries laparoscopic ally .
DL is not a substitute for open laparatomy
especially in the presence of haemoperitonium or
contamination.

Liver
The majority of livers injuries occur as a
result of blunt injury which may burst liver .
The use of CT for the evaluation of trauma
patient ( liver , spleen , kidneys ) .
The liver is a solid organ and may be
compressed between the forces and the rib
cage or vertebral column.
Penetrating trauma relatively common ( stab
wound , bullets cause significant damage ).
Not all penetrating wounds require operative
management.

Pringle : The inflow from the portal triad is
controlled by pringle maneuver .
Plug :any holes can be plugged directly .

Splenic injury occurs from direct trauma ,
Overlaying ribs ( ninth to 11th ribs ) .
Most isolated splenic injuries espacially in
children can be managed non operatively .
In adults in the presence of other injuries
laparatomy may become indicated depending on
physiological instability .
At laparatomy direct splenorrhaphy , or packed ,
repaired or placed in a mesh bag.
Selective embolisation of spleen can play a role .
Following splenectomy : changes in blood
physiology ,raised platelets count > 1000000 ,
and white cell count rises and mimic sepsis.

Due to blunt trauma .
CT scan the main test of value .
Amylase may be low or normal ( low amylase
in 50% of cases .) .
Treatment : conservative , closed suction
drainage , distal pancreatectomy , Wipple,s
procedures .
