Severity of Traumatic Injury to the Duodenum

The severity of traumatic injury to the duodenum can be graded based on 5 clinical parameters associated with the injury.

Parameters:

(1) agent of injury

(2) circumference of wall involved

(3) portion of the duodenum involved

(4) interval in hours from time of injury to time of repair

(5) injury also involving the common bile duct

Parameter	Mild	Severe
agent for injury	stab	blunt, or missile
size	< 75% of wall	>= 75% of wall
portion of duodenum involved	part 3 and/or 4	part 1 and/or 2
interval in hours from injury to repair	< 24 hours	>= 24 hours
injury to common bile duct	absent	present

after Table 1, page 534

where:

• The original table had only "<" and ">" for size and interval.

Interpretation:

• If any of the features associated with a severe injury are present, then the injury is considered severe.
