Paramesenteric gutters

Paramesenteric Gutters are anatomical structures found in the human body, specifically in the abdominal cavity. They are spaces between the mesentery and the peritoneum, and are of clinical significance due to their role in the spread of intraperitoneal fluid.

Etymology

The term "Paramesenteric" is derived from the Greek words "para", meaning beside, and "mesenteron", meaning middle intestine. The term "gutter" is used to describe the shape and function of these spaces, as they are similar to gutters on a house, collecting and directing fluid.

Anatomy

Paramesenteric gutters are located in the abdominal cavity, between the mesentery and the peritoneum. There are two main paramesenteric gutters: the right and left paramesenteric gutters. The right paramesenteric gutter is located between the right side of the mesentery and the right parietal peritoneum. The left paramesenteric gutter is located between the left side of the mesentery and the left parietal peritoneum.

Clinical Significance

Paramesenteric gutters are clinically significant as they can act as pathways for the spread of intraperitoneal fluid. This can include infectious fluid, such as in the case of peritonitis, or malignant fluid, such as in the case of peritoneal carcinomatosis. Understanding the anatomy of the paramesenteric gutters can aid in the diagnosis and treatment of these conditions.
