What does eventration refer to in surgical terms?

Eventration in surgical terms specifically refers to the protrusion of abdominal contents through a defect in the abdominal wall, often following surgery. This condition often arises after procedures involving the abdomen where the integrity of the abdominal wall may be compromised. When the layers of the abdominal wall—skin, subcutaneous tissue, muscles, and fascia—do not heal appropriately, part of the intestines or other abdominal organs may bulge through these layers, leading to eventration.

Understanding this definition helps differentiate eventration from other surgical complications. For instance, wound separation after surgery, while it shares similarities with eventration in terms of causing visible changes at the surgical site, does not involve the actual protrusion of internal contents. Similarly, the formation of a tubular tract can be related to issues like fistulas, which is a different surgical concern involving an abnormal connection between two cavities. Lastly, the infection of a cyst near the tailbone pertains to a localized infection rather than the broader concern of abdominal contents protruding, which is central to the concept of eventration. Therefore, identifying eventration correctly is crucial for surgical assistants, as it directly relates to patient management and potential interventions following abdominal surgery.
