The regenerating epithelium completely covers the ulcer floor, and the white coating has disappeared. The area appears markedly red due to the presence of many new capillaries. sakitamiwa classification

The system classifies ulcers based on visual changes during upper gastrointestinal endoscopy. This inconsistency made it difficult to accurately track

Before the widespread adoption of endoscopic staging systems, the clinical description of gastric ulcers was often subjective and varied between different physicians and institutions. This inconsistency made it difficult to accurately track a patient's progress, compare the effectiveness of different treatments, or design meaningful clinical trials. The Sakita-Miwa classification was developed to solve these problems by providing a clear, objective, and universal framework.

The regenerative epithelium nearly covers the mucosal break. The ulcer is significantly smaller, and the coating is minimal. 3. Scarring Stage (S) This stage indicates complete or near-complete healing.
