Peritoneal recesses

There are other smaller recesses including those around the duodenojejunal flexure, cecum, and the sigmoid colon.

These gutters are clinically important because they allow a passage for infectious fluids from different compartments of the abdomen.

For example; fluid from an infected appendix can track up the right paracolic gutter to the hepatorenal recess.

[2] The paraduodenal recess proper is situated posterior to the superior extremity of the inferior mesenteric vein.

This paraduodenal recess is clinically and surgically important: an internal hernia protruding into the recess may obstruct the inferior mesenteric vein or cause a thrombus to form within it, and the vein may be sectioned during surgical repair of such a hernia.
