gastrocolic

Gastrocolic is a combining form used in anatomy and medicine to denote a relationship between the stomach (gastro-) and the colon (colic/colon). It appears in terms describing structures or processes that involve both organs, such as the gastrocolic ligament and the gastrocolic reflex.

The gastrocolic ligament is a portion of the greater omentum that extends from the greater curvature of the stomach to the transverse colon. This peritoneal connection helps stabilize the organs within the upper abdomen and is a landmark in abdominal surgery, particularly during procedures that involve mobilization of the stomach or colon.

The gastrocolic reflex is a physiological response in which distension of the stomach after a meal triggers increased motility of the colon, promoting bowel movements. This reflex is mediated by the enteric nervous system and autonomic pathways, and it contributes to postprandial changes in bowel activity. Variations in the strength or timing of the reflex can be observed among individuals and in certain functional gastrointestinal disorders.

Clinically, gastrocolic terminology is used to describe anatomical relationships or procedural considerations that involve both the stomach and colon. Understanding gastrocolic structures and reflexes supports surgical planning, diagnostic evaluation in gastroenterology, and the interpretation of postprandial gastrointestinal function.
