 Completion of the circulatory pathway takes place
caudally by redirection of fluid into the pelvis through the inframesocolic compartment13 (Fig.3).In pathologic conditions the excessive fluid collects in well-defined areas of stasis or arrested flow including the
peritoneal recesses of the pelvis (pouch of Douglas in women and retrovesical space in men), the right lower
quadrant (near the termination of the small bowel mesentery at the ileocaecal junction), the superior aspect of the
sigmoid mesocolon and the right paracolic gutter.
