A

Biliary bypassGastric bypassDouble bypass

82
Q

What is involved in Whipple’s operation?

A

Part of the stomach and the head of the pancreas are removed - remaining stomach and pancreas are joined separately to the small intestines

83

Body and tail of the pancreas and usually the spleen are removed

84
Q

Biliary bypass?

A

Rerouting the flow of bile from the common bile duct into the intestine bypassing the pancreas

85
Q

Gastric bypass?

A

Pancreatic tumour can block the duodenum - surgery directly joins the stomach and the small intestine
