Siewert classification
Siewert Classification
The Siewert Classification (pronounced: /ˈsiːvɛrt/), is a medical classification system used in the field of gastroenterology. It was named after the German surgeon, Heinz-Johannes Siewert, who first proposed the system.
Etymology
The Siewert Classification is named after Heinz-Johannes Siewert, a renowned German surgeon who specialized in gastroenterology. Siewert's work in the field led to the development of this classification system.
Definition
The Siewert Classification is a system used to categorize adenocarcinoma of the esophagogastric junction (AEG). This classification system is based on the anatomical location of the tumor's epicenter and is divided into three types:
- Type I: Adenocarcinoma of the distal esophagus, also known as Barrett's esophagus.
- Type II: True carcinoma of the cardia, or the area where the esophagus joins the stomach.
- Type III: Subcardial gastric carcinoma that infiltrates the esophagogastric junction from below.
Usage
The Siewert Classification is widely used in medical practice and research to determine the most appropriate surgical approach for patients with AEG. It helps in predicting the prognosis and determining the optimal surgical strategy, whether it be esophagectomy, gastrectomy, or a combined approach.
