Correct Answer � B
Explanation

|
Answer B) Gastrohepatic ligament
The space described is the lesser sac. The ligament that must be cut is a part of the lesser omentum.
Gastrohepatic ligament
-
The gastrohepatic ligament connects the lesser curvature of the stomach with the liver.
-
Together with the hepatoduodenal ligament, it forms the lesser omentum, which separates the anterior greater sac from the posterior lesser sac.
-
Access to the lesser sac, as during pancreatic surgery, can be achieved by cutting the gastrohepatic ligament.
-
The lesser sac can also be accessed through the gastrocolic ligament (part of the greater omentum), gastrosplenic ligament, splenorenal ligament, and through the transverse mesocolon.
