Section 6.6 – Mobilisation of the periphery of the mid-region fold
The next step is to detach the small intestinal mesentery and continuous right mesocolon
The small intestine is retracted to the right
Exposing the base of the small intestinal region of mesentery
The ileocaecal junction is also retracted to the right
This exposes the small intestinal region of mesentery at this level
The region where the small intestinal mesentery continues as the right mesocolon
Is obscured from direct view by the peritoneal reflection
At the peritoneal reflection, parietal peritoneum is reflected onto the small intestinal region of mesentery
This region of reflection is called the small intestinal region of the reflection
It is sharply divided through, beginning at the DJ flexure and continuing
Diagonally towards the ileocaecal level
The ileocaecal region of the reflection is identified and divided
After this, the undersurface of the mesentery becomes apparent with fascia underneath
Mesofascial separation enables further detachment of the mesentery from the posterior abdominal wall
