gastroduodenostomy
The Pylorus (the valve between the stomach and duodenum is the pyloric valve)
the jejunum is the middle portion of the small intestine
The first portion of the small intestine is a small curved portion called "duodenum".
duodenum
In your small intestine, a portion called the duodenum.
The first portion of the small intestine, the duodenum, is straight. The second portion, the ileum, is coiled.
In adults the jejunum is found in the small intestine and lies between the duodenum and the ileum. The lining of the jejunum absorbs small food particles which have previously been digested in the duodenum.
The portion of the stomach closest to the small intestine is called the pylorus. This region controls the flow of partially digested food from the stomach into the small intestine for further digestion and absorption.
An operation where a portion of the lower stomach (pylorus) is removed. The remaining portion of the stomach is then connected to the duodenum (first part of the small intestine).
This procedure is known as a gastrojejunostomy (Billroth II). It is commonly performed in cases of gastric outlet obstruction, such as in pyloric stenosis or gastric cancer, to allow for proper digestion and passage of food from the stomach into the small intestine. This surgical technique helps to bypass the obstructed area and restore gastrointestinal continuity.
pharynx to part 2 of the duodenum
The top portion of the intestine is called the duodenum. It is the first part of the small intestine where much of the digestion and absorption of nutrients takes place. It receives partially digested food from the stomach and plays a key role in breaking down nutrients for absorption into the body.
