The Kocher manoeuvre is a surgical procedure to expose structures in the retroperitoneum behind the duodenum and pancreas.
[citation needed] The Kocher manoeuvre involves the following steps: In 1895, Jourdain first talked about moving the duodenum in the body.
[3] In children, it's even more flexible, but as they grow, it sticks to the back of the belly and is covered in a layer of peritoneum.
[3] Kocher also knew that the duodenum and pancreas are initially hanging freely in the belly, connected by a mesentery.
[3] Since Kocher's time, we've learned more about how the duodenum and pancreas develop and settle into their final position in the body.
