The term "cardia" has its roots in the Greek word "kardia," which means heart. However, in anatomical terms, it refers to a specific region within the digestive system. The Merriam-Webster New International Unabridged Dictionary defines cardia as either the opening of the esophagus into the stomach or the cardiac end of the stomach. This dual definition highlights the ambiguity surrounding the term, as it can refer to the proximal stomach, the distal esophagus, or the rim or hole between the two.
To provide a more precise definition, some researchers have described the cardia as encompassing 2 cm of the distal esophagus and 2 cm of the proximal stomach. This definition aims to clarify the anatomical boundaries of the cardia, which includes the esophagogastric junction (EGJ) and the squamocolumnar junction (SCJ). In a study of 50 Japanese autopsy cases, the distance between the EGJ and the SCJ was found to be 0-10 mm, with a mean of 3 mm, indicating that the SCJ is not located below the EGJ.
The cardia is a region of interest not only for its anatomical ambiguity but also for its histopathological features. Various conditions such as pancreatic metaplasia, small leiomyomas, inflammatory EGJ polyps, carditis, and Barrett's epithelium are often recognizable in the cardia. The presence of ducts of esophageal glands proper in the metaplastic mucosa can be used to diagnose short-segment Barrett's esophagus, particularly when the segment is less than 3 cm in length.
In summary, the cardia is a term with a somewhat ambiguous definition, referring to the area around the gastroesophageal junction. Anatomically, it includes parts of both the distal esophagus and the proximal stomach. Histopathologically, it is a region where various conditions can be observed, making it a significant area of study in gastroenterology. Understanding the precise boundaries and features of the cardia is crucial for accurate diagnosis and treatment of related conditions.
