5-434.1:

Part of your stomach has been surgically removed.

The stomach is located in the upper abdomen. The stomach has a curved shape, creating a big curve and a small notch. The stomach is made up of different sections. Food reaches the entrance to the stomach through the gullet (oesophagus). The food is then transported into the body of the stomach. The fundus of the stomach is located at the top of the stomach. Air often collects there. There is a small extension further down in the stomach. This is the section in front of the end of the stomach or pyloric orifice. There is a sphincter muscle, the pylorus, at the end of the stomach. The pylorus transports the food in portions into the small intestine.

The operation involved cutting out your cardia.

The lowest section of your oesophagus was also removed. The resulting oesophagus end and the remains of your stomach were then stitched together. To do this, the remains of your stomach were pulled up through your diaphragm into your chest cavity. The diaphragm is located in the ribcage. The diaphragm separates the chest cavity from the abdominal cavity. The stomach is usually below the diaphragm in the abdomen.
