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. A less obvious medial paracolic gutter may be formed, especially on the right side, if the colon ...
Peritoneal recesses (or peritoneal gutters) are the spaces formed by peritoneum draping over viscera. [1] The term refers mainly to four spaces in the abdominal cavity; the two paracolic gutters and the two paramesenteric gutters. There are other smaller recesses including those around the duodenojejunal flexure, cecum, and the sigmoid colon.
The paramesenteric gutters (paramesenteric recesses or infracolic spaces) are two peritoneal recesses – spaces in the abdominal cavity between the colon and the root of the mesentery. There are two paramesenteric gutters; the left paramesenteric gutter and the right paramesenteric gutter.
The right paracolic gutter is continuous with the right and left subhepatic spaces. The epiploic foramen allows communication between the greater sac and the lesser sac. [ 2 ] The peritoneal space in males is closed, while the peritoneal space in females is continuous with the extraperitoneal pelvis through openings of the fallopian tubes , the ...
During mobilization of the small intestinal mesentery from the posterior abdominal wall, this fold is incised, allowing access to the interface between the small intestinal mesentery and the retroperitoneum. The fold continues at the inferolateral boundary of the ileocaecal junction and turn cephalad as the right paracolic peritoneal fold. This ...
Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal. [1] This is different from organs that are not retroperitoneal, which have peritoneum on their posterior side and are suspended by mesentery in the abdominal cavity.
The rectouterine pouch, being the lowest part of the peritoneal cavity in a woman at supine position, is a common site for the spread of pathology such as ascites, tumour, endometriosis, pus, etc. As it is the furthest point of the abdominopelvic cavity in women, it is a site where infection and fluids typically collect.

The hepatorenal recess [1] (subhepatic recess, pouch of Morison or Morison's pouch) is the subhepatic space that separates the liver from the right kidney.As a potential space, the recess is not normally filled with fluid.
