Show Hint
A leak from a minor duct still in continuity is the lowest grade.

- Type A
- Type B
- Type C
- Type D
Show Solution
The Correct Option is A
Solution and Explanation
Anchor on what each Strasberg letter means and match the lesion. The scheme runs A through E for post-cholecystectomy biliary injuries, from trivial leaks up to major duct transections.
A cystic duct stump that gives way, a cystic duct blow out, is a bile leak from a small duct that is still connected to the rest of the biliary tree. That definition is exactly Strasberg Type A, which also includes leaks from small ducts of Luschka in the liver bed.
The other types do not fit. Type B is an occluded aberrant right sectoral duct, Type C is that same kind of aberrant duct transected and leaking, and Type D is a partial side-wall injury of the common duct. The big circumferential common-duct injuries are Type E. None of these describes a simple cystic stump leak.
$\text{cystic duct stump leak (in-continuity minor duct)} = \text{Type A}$
\[\boxed{\text{Type A}}\]
