What is paracolic space?
What is paracolic space?
The paracolic gutters (paracolic sulci, paracolic recesses) are peritoneal recesses – spaces between the colon and the abdominal wall.
What is a retroperitoneal space?
The retroperitoneum is an anatomical space located behind the abdominal or peritoneal cavity. Abdominal organs that are not suspended by the mesentery and lie between the abdominal wall and parietal peritoneum are said to lie within the retroperitoneum. Several individual spaces make up the retroperitoneum.
What is the intraperitoneal space?
Intraperitoneal space is the space of the abdomen completely surrounded by the peritoneum. The organs inside the intraperitoneal space are mobile. Some examples of such organs are the stomach, esophagus, jejunum, ileum, and transverse and sigmoid colon.
What spaces does the right paracolic gutter connect?
The right paracolic gutter is a relatively wide space between the ascending colon and the lateral abdominal wall. It is in continuity with the right subphrenic space and continues cranially lateral to the liver to the right hemidiaphragm.
What is left paracolic gutter?
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. It is continuous with the peritoneum as it descends into the pelvis over the pelvic brim.
Why is retroperitoneal space necessary?
The retroperitoneal space provides access to the lumbar plexus, origin and course of peripheral nerves, and the lateral lumbar spine as well as the ventrolateral spinal canal.
Is the liver retro or intraperitoneal?
Intraperitoneal organs include the stomach, spleen, liver, first and fourth parts of the duodenum, jejunum, ileum, transverse, and sigmoid colon.
What is paracolic gutter?
The paracolic gutters (paracolic sulci, paracolic recesses) are spaces between the colon and the abdominal wall. These gutters are clinically important because they allow a passage for infectious fluids from different compartments of the abdomen.
What is paracolic gutter ascites?
When larger amounts of ascites are present, the fluid accumulates in the paracolic gutters, causing progressive centralization of bowel loops. The fluid may accumulate in a triangular configuration within the leaves of the small bowel mesentery or adjacent to bowel loops.
What is the structure of a paracolic gutter?
Structure. There are two paracolic gutters: The right lateral paracolic gutter. The left medial paracolic gutter. 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.
What is the difference between paracolic and subphrenic?
Involvement of the gutter The paracolic gutter is associated with a subphrenic abscess. The right and left paracolic gutter are connected to subphrenic spaces proximally and to the pelvic area at the distal end. Infected peritoneal fluids get a passageway through these gutters to other compartments of the abdominal cavity.
What is the smaller right infracolic space?
The smaller right infracolic space is a triangular region whose base is the transverse mesocolon, right border is the medial wall of the ascending colon and left border is the lateral part of the root of the small intestinal mesentery. The apex of the space continues inferiorly towards the ileocecal junction and may contain the vermiform appendix.
Where is the right infracolic compartment located?
Right Infracolic Compartment. The infracolic compartment is located caudal to the transverse mesocolon. The oblique root of the mesentery of the small intestines further divides the compartment into a left and right infracolic compartment.
