5-447.5:

You have had another operation on your stomach. The operation changed the join between your stomach and your small intestine.

The stomach is located in the upper abdomen. The stomach has a curved shape, and is connected to the gullet (oesophagus) at its upper end and with the first part of the small intestine at its lower end. Between the stomach and the small intestine there is a circular sphincter, the pylorus. The inside of the stomach is lined with mucous membrane.

Previous surgery involved removing some of your stomach. The upper part of your small intestine was then stitched shut. A part of your small intestine further down was then stitched, at the side, to the remaining section of your stomach.

The new operation removed the join between your small intestine and your stomach. Your small intestine was severed at that point. The open, top end of your small intestine was stitched to your stomach. The open, bottom end of your small intestine was stitched to your small intestine lower down.

After this new surgery, food is now still getting from your stomach straight to the part of your small intestine that is lower down. So food is still not being moved through the upper section of your small intestine. However, the digestive juices from your liver and pancreas are still flowing into that section of your small intestine. The digestive juices then blend with the food lower down in the small intestine.
