5-447.1:

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 remaining part of your stomach was then stitched to your small intestine.

The new operation involved separating your stomach and your small intestine from each other. 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.

After this new surgery, food is now getting from your stomach straight to the part of your small intestine that is lower down. So food is no longer 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.
