In juvenile polyposis syndrome, young children develop multiple polyps throughout the gastrointestinal tract, especially in the large intestine, and unfortunately some of those polyps can develop into colon cancer at some point in their life.
The intraperitoneal space contains the first part of the duodenum, all of the small intestines, the transverse colon, sigmoid colon, and the rectum; the retroperitoneal space contains the distal duodenum, ascending colon, descending colon, and anal canal.
Now, the walls of the gastrointestinal tract are composed of four layers.
The outermost layer is the serosa for the intraperitoneal parts, and the adventitia for the retroperitoneal parts.
Next is the muscular layer, which contracts to move food through the bowel.
After that is the submucosa, which consists of a dense layer of tissue that contains blood vessels, lymphatics, and nerves.
