Adhaesio

Adhaesio is a term derived from Latin that denotes adhesion or sticking together. In medical and anatomical usage, the form adhæsio or adhæsiones appears as a root in discussions of adhesions, which are fibrous bands that connect tissues or organs that are normally separate.

In clinical context, adhaesiones refer to the formation of scar tissue that binds surfaces such as organs, membranes, or tissue planes. They typically arise after tissue injury, inflammation, surgery, or infection. The process begins with inflammation and fibrin deposition, followed by organization and remodeling that can mature into collagenous scar tissue. When adhesions form, they may restrict movement, cause pain, or impair organ function, depending on their location.

Common sites include the peritoneal cavity, where abdominal or pelvic surgeries can lead to peritoneal adhesions; the pleural space after chest injuries or infections; and joints when intra-articular adhesions limit range of motion. Some adhesions remain asymptomatic and are discovered incidentally, while others require intervention.

Diagnosis is based on clinical assessment and history; imaging and, when necessary, surgical exploration may be employed to evaluate the extent and impact of adhesions. Treatment ranges from watchful waiting and physical therapy to surgical adhesionlysis, which aims to release the abnormal connections. Preventive measures during procedures—such as meticulous technique and the use of anti-adhesion barriers—are often emphasized to reduce recurrence.

Outside medicine, the term is less commonly used in English, with many languages employing cognate words to describe similar concepts of tissue sticking and scar formation. See also: adhesion, adhesiolysis, scar tissue.
