The detachment of peritoneal adherences as forms the basis of many
gastrointestinal surgical procedures is shown in a dissection specimen.
The greater omentum is detached from the transverse colon, giving access
to the omental bursa. The descending colon and mesocolon are detached,
the so-called left visceral rotation. The Cattel-Braasch manoeuvre -
detaching and lifting the ascending (meso) colon and small intestines,
to give access to the peritoneal back wall - is demonstrated. This also
unveils the hidden part of the duodenum. Finally, it is shown how the
mesocolons and the mesentery of the small intestine form a continuity
that rotated with the intestines embryologically.
