Arkansas Trauma System Evidence-Based Guidelines for

Abdominal Trauma- Advanced Trauma Techniques-

Upper Abdomen

Section Editor: Charles D. Mabry MD FACS

Introduction-

Trauma to the abdomen remains one of the most common major injuries for humans. The first

evidence-based guideline regarding abdominal trauma covered the pre-hospital and emergency

department evaluation and treatment of abdominal trauma. This second guideline is aimed at the

patient with major injuries to the upper abdominal organs. The remaining two guidelines will cover

trauma to the lower abdominal / pelvic area and damage control / open abdomen surgery.

Upper Abdominal Trauma- Liver, Stomach, Duodenum, Pancreas, and Spleen,

Liver trauma:

Trauma to the liver is one of the more common major category of traumas of the abdomen, due in

part to the size of the liver, and to the ease that blunt trauma to the upper abdomen and lower

chest can injure the liver. Despite its size and frequency of injury, non-operative management of the

liver has become much more common and accepted, than operative repair of the liver. Even

isolated penetrating injuries to the dome of the liver can be managed without open exploration in

some instances. 1 Non-operative management does include the use of interventional radiology as a

method to control bleeding. 2,3

Diagnosis of liver trauma can be made with a FAST ultrasound exam, but abdominal CT scan with IV

contrast remains the primary method to gage the extent of overall liver injury as well as to detect

significant bleeding via a “blush” seen on the CT scan. Thus, it is important to promptly evaluate the

patient with abdominal injury with the proper CT scan in order to determine prognosis as well as

anticipated treatment. 4 If your trauma center doesn’t have interventional radiology capability and

the patient has a suspected major liver injury, then consideration of transferring the patient to a

center that does have this capability should be entertained. Liver injury can be graded, and

although the grade of liver injury may not always determine the need for open surgery, a grading

scale is useful for communication to other providers about the extent of injury and for a prognostic

indicator of likely later bleeding and mortality. Most surgeons use the AAST grading scale for liver

injury, which was updated in 1994 to include CT scan findings. 5 [Figure A] It is important to

consider including delayed phase imaging of the liver for the trauma CT scan protocol to visualize

the portal and hepatic veins to detect any major vascular injury.

Predictors of need for open surgery for the liver injury patient revolve around the key factors of: 1)

ongoing hemodynamic instability, including a shock index > 1, 2) ongoing hemorrhage, other

abdominal injury requiring surgery, presence of a blush on angiography, and 3) a low GCS. 6 , 7

Operative management involves several techniques including four quadrant packing to control

hemorrhage and compress the liver as a first step, portal clamping (the Pringle maneuver), and

balloon tamponade (Foley catheter or Fogarty balloon) and direct ligation of arterial bleeding. See

[Figure B] for a good algorithm for operative management of liver injury. 8 [Figure C] shows the

standard liver segments that are typically numbered. 9 As with all traumas, avoidance of

hypothermia, coagulopathy, and acidosis is critical, along with the use of component blood therapy

all-the-while avoiding excessive IV fluids.

Pancreatic and Duodenal Trauma:

While infrequent, injuries to the pancreas and duodenum are well known and respected for their

associated major complications. Detection of injury to the duodenum and pancreas remain difficult

in many cases, and delayed presentation of injury is not uncommon, despite good front-end

evaluation. Thus, a high index of suspicion is necessary to avoid a delay in diagnosis which almost

always increases morbidity and mortality.

MVA (steering wheel) injury is perhaps the most common mechanism for injury to this area, where

these organs are crushed against the spine. One marker for potential pancreas and duodenum (and

small bowel) injury is a compression fracture of the lower thoracic and upper lumbar spine (Chance

fracture). 10 Evaluation with CT scans with IV contrast is often necessary to detect bleeding or small

leaks from the pancreas or duodenum. For isolated blunt or penetrating injuries to upper abdominal

area (e.g. knife injury, handle-bar, or bull / horse stomping) oral contrast should also be considered

to rule out occult injuries to the duodenum. 11

The superior mesenteric artery and vein provides an anatomic marker that divides these injures into

two zones: 1) to the patient’s left are pancreatic tail injuries and 2) to the patient’s right are often

combined duodenal, pancreas, and common bile duct catastrophes. After the anatomic zone of

injury is determined, the next major question to answer is whether or not the pancreatic duct is

injured or if the duodenum is leaking. 12, 13

Injuries to the tail of the pancreas are perhaps the most straightforward of all of the possible

combinations of duodenal and pancreatic injuries. These often involve the spleen, but if minor and

there are no other injuries, and the pancreatic duct is intact, these can often be managed non-

operatively. More severe injuries in this area can be managed by a distal pancreatectomy and

splenectomy, with placement of drains. Injures to the patient’s right of the superior mesenteric

vessels are more problematic. If there is minor injury with no leakage, the nasogastric

decompression and total parenteral nutrition often will be all that is needed. More severe injury,

however, requires open surgery, debridement, drainage, and possible diversion. 12, 13 The algorithm

in [Figure D] is from Up to Date, and the reader is urged to read this entire document for

management options and techniques for these types of complex injuries. 10 These injuries are not

only complex but deadly, and early referral to a Level I trauma center is an excellent choice to

consider.

Both the pancreas and duodenum are largely retroperitoneal organs and they lie in Zone I of the

retroperitoneum, along with the aorta and inferior vena cava. [See Figure E]. As such, large

hematomas in Zone I are typically explored to rule out significant sources of hemorrhage from major

vessels.

Splenic Trauma

Similar to the liver, trauma to the spleen is now being management more frequently non-

operatively, especially if there are no other reasons to explore the abdomen. For the

hemodynamically unstable patient, with a positive FAST scan of the abdomen, prompt transfer to

the operating room should be the first option considered. For trauma centers without general

surgery capability, stabilization and expeditious transfer to an appropriate trauma center should

occur. 14 For the stable patient, evaluation with a CT scan with IV contrast is the best tool to help

understand the extent and prognosis for splenic trauma.

While the grade of splenic injury doesn’t always determine the need for open surgery, as a general

rule, non-operative management fails more frequently as the grade of injury increases, especially

for Grades III to V. The American Association for the Surgery of Trauma (AAST) published the most

widely used splenic injury grading scale in 1989, and this was updated in 2018 to incorporate CT

scan findings [Figure F]. 15 16 17 Active bleeding detected by an arterial blush on CT scan can often be

managed by interventional radiology and embolization of the bleeding artery. 18 Other markers for

failure of non-operative management are increasing age (more fragile splenic capsule and more

atherosclerotic arteries) and significant head injury (inability to tolerate hypotension). 19 Non-

operative management should not be attempted for significant splenic trauma (Grades III and

above) in a center without the capability of immediate open surgery &/or angiography.

For patients who undergo splenectomy, especially for those younger than 16 years of age, the

standard recommendations are to immunize the patient after 14 days against pneumococcal

pneumonia, meningitis, and influenza, to avoid the 3-5% post-splenectomy sepsis syndrome. 20 21
