Pancreatectomy Procedure

Which part of the pancreas is located within the curve of the duodenum and may be embedded in its wall?

• Neck

• Body

• Head

• Tail

Answer explanation

The head of the pancreas is located within the curve of the duodenum and can be embedded in its wall, making it the correct answer. The neck, body, and tail do not have this anatomical relationship.

What is the primary function of the islets of Langerhans in the pancreas?

• Digestive enzyme secretion

• Blood sugar regulation

• Bile production

• Absorption of nutrients

Answer explanation

The islets of Langerhans are clusters of cells in the pancreas that primarily regulate blood sugar levels by producing hormones like insulin and glucagon, making 'Blood sugar regulation' the correct answer.

Which vascular structure is commonly clamped during resection of the pancreas to control bleeding?

• Splenic artery

• Superior mesenteric vein

• Satinsky-type vascular clamp across the pancreas

• Inferior vena cava

Answer explanation

The Satinsky-type vascular clamp is specifically designed to occlude blood vessels during pancreatic resection, effectively controlling bleeding. Other options do not serve this purpose directly.

The pancreas has a well-defined capsule that separates it from surrounding structures.

• True

• False

Answer explanation

The pancreas does not have a well-defined capsule; it is surrounded by loose connective tissue, which allows for flexibility and movement. Therefore, the statement is false.

What type of anastomosis is typically performed during reconstruction after a pancreatectomy?

• End-to-end pancreaticogastrostomy

• Side-to-side jejunojejunostomy

• End-to-side pancreaticojejunostomy using a Roux-en-Y loop

• End-to-end duodenojejunostomy

Answer explanation

The end-to-side pancreaticojejunostomy using a Roux-en-Y loop is preferred after pancreatectomy as it allows for better drainage of pancreatic secretions and reduces complications compared to other anastomosis types.
