jejunum

The hormone-rich organ, connecting the stomach to another part of the intestine called the jejunum, has prompted the development of various procedures to bypass or intervene on the duodenum.

In gastric bypass, a surgeon reroutes the digestive system so that the stomach empties directly into the middle of the small intestine, bypassing a section called the duodenum and jejunum.

Normally the jejunum receives only digested mush, as nutrients have already been absorbed in the duodenum, explained lead researcher Tony Lam.

The latter of these authors says that the ileum and jejunum in the bodies of those who died of this disease were frequently found interspersed with tubercles, inflamed and ulcerated in different parts.

The pyloric orifice is always more affected than the cardiac; the duodenum, jejunum, and ileum, are inflamed; the cæcum is enlarged, inflamed, and generally impacted.
