Left Paracolic Gutter Anatomy

The left medial paracolic gutter.

Left paracolic gutter anatomy.

The left lateral paracolic gutter. The main paracolic gutter lies lateral to the colon on each side. 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. The right paracolic gutter is a component of the right inframesocolic space continuous superiorly with the right subhepatic and right subphrenic spaces it is larger than the left paracolic gutter which is partially separated from the left subphrenic spaces by the phrenicocolic ligament.

The left and right supramesocolic spaces usually communicate freely with one another and include the perihepatic left subphrenic and perisplenic spaces fig 8a 8b. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon. Left lateral paracolic gutter similar to the right the left lateral paracolic gutter extends from the left colic splenic flexure adjacent to the lateral wall of the descending colon and medial to the left lateral part of the anterior abdominal wall to its termination at the at the sigmoid mesocolon s lateral edge. It is smaller than the right paracolic gutter.

The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon. The left paracolic gutter is a component of the left inframesocolic space partially separated from the left subphrenic spaces by the phrenicocolic ligament. This gutter is however much smaller because it is restricted at the top by the phrenicocolic ligament or the ligament supporting the top left edge of the colon. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon.

The left medial paracolic gutter. The right lateral paracolic gutter. The left lateral paracolic gutter. Both paracolic spaces are in continuity with the pelvic peritoneal spaces.

Both paracolic spaces are in continuity with the pelvic peritoneal spaces. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon. The main paracolic gutter lies lateral to the colon on each side. The left gutter runs between the descending colon and the abdominal wall and just like the right gutter empties into the lower abdomen and pelvic area.

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. The main paracolic gutter lies lateral to the colon on each side. The left lateral paracolic gutter the right lateral paracolic gutter.
