The paracolic gutter ( paracolic sulci , paracolic recesses ) is a space between the colon and the abdominal wall.

Structure

There are two paracolic gutters:

• Right lateral paracholic ditch.
• The left medial paracolic gutter.

The right and left paracolic plaque is the peritoneal niche of the posterior abdominal wall located alongside the ascending and descending colon. The main paracol parasol is located on the lateral colon on each side. Unclear medial paracolic talacs may form, especially on the right side, if the large intestine has a short mesenterium for a portion of its length. The right lateral (right) parasol goes from the superiolateral aspect of the colonic liver arch, downward the lateral aspect of the ascending colon, and around the cecum. This continues with the peritoneum as it descends into the pelvis above the pelvic pelvis. Furthermore, this is continuous with the peritoneum lining the hepatorenal sac and, through the epiploic foramen, the lower sac.

Variations

The right limb parasol larger than the left, which, along with the partial barrier provided by the phrenicological ligament, may explain why appropriate subphrenic collections are more common than the left subphrenic collections.

Function

These gutters are clinically important because they allow a channel for infectious fluid from different abdominal compartments. As an example; the fluid from the infected appendix can track the right paracolic gutter into the hepatorenal recess.

Clinical interests

Bile, pus or blood released from innards anywhere along the length can run along the gutter and collect in a location far enough from the organ of origin. In the supine patient, the infected fluid from the right iliac fossa can rise to the gut for entry into the lower sac. In patients treated in a sitting position, fluids from the stomach, duodenum or gallbladder can flow in the gut to collect in the right iliac fossa or pelvis and may mimic acute appendicitis or form a pelvic abscess. The right limb parasol larger than the left, which, along with the partial barrier provided by the phrenicological ligament, may explain why appropriate subphrenic collections are more common than the left subphrenic collections.
