Paracolic gutter ct anatomy.

A less obvious medial paracolic gutter may be formed especially on the right side if the colon possesses a short mesentery for part of its length. There are two paracolic gutters. The main paracolic gutter lies lateral to the colon on each side. It predominantly flows up the right paracolic gutter which is deeper and wider than the left and is partially cleared by the subphrenic lymphatics.

There are two paracolic gutters in the body the right and left lateral paracolic gutter. The left lateral paracolic gutter. The phrenicocolic ligament separates the left paracolic gutter from the left supramesocolic space it is continuous with the peritoneum of the left lateral aspect of the transverse mesocolon and the splenorenal ligament adjacent the splenic hilum 1 it attaches to the parietal peritoneum along the posterolateral aspect of the diaphragm at the level of the eleventh rib. Right paracolic gutter there are paracolic gutters adjacent to the infracolic compartments that are clinically significant.

It is larger than the left paracolic gutter which is partially separated from the left subphrenic spaces by the phrenicocolic ligament. The left medial paracolic gutter. The paracolic spaces gutters are located lateral to the peritoneal reflections of the left and right sides of the colon fig 8a. Rarely the appearance of thickened fascia may be simulated on ct supine scans by intraperitoneal fluid within posterior peritoneal recesses particularly on the left 17 52 53 fluid layering in a deep left paracolic gutter may mimic thickening of the lateroconal fascia and a portion of the posterior renal fascia.

The paracolic gutters paracolic sulci paracolic recesses are spaces between the colon and the abdominal wall. Etiologically it means a channel adjacent to the abdominal wall. Paracolic gutters are open areas between the wall of the abdomen and the colon. On the right hand side the right lateral paracolic gutter is found lateral to the ascending colon and medial to the lateral part of the anterior abdominal wall.

It is the depression between the postero lateral wall of the abdomen and the lateral margins of the ascending and descending colon. As the fluid continues superiorly into the inferior extension of the splenorenal recess and perhaps to some degree medially within the unusual variant of a retropancreatic recess. There are watershed regions in the peritoneal cavity that are areas of fluid stasis. The right paracolic gutter is a component of the right inframesocolic space continuous superiorly with the right subhepatic and right subphrenic spaces.

The right lateral paracolic gutter. Both paracolic spaces are in continuity with the pelvic peritoneal spaces. These gutters are used to drain infectious material away from the essential internal organs. The right paracolic gutter is larger than the left and communicates freely with the right subphrenic space.

The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon.
