The defect is significantly smaller than in H1, and the regenerating epithelium covers most of the ulcer floor. The white coating is reduced to only about a quarter or one-third of its original area. 3. Scarring Stage (S)
The Sakita-Miwa classification remains an essential tool in endoscopic diagnostics. By providing a clear, step-by-step breakdown of ulcer healing—A1, A2, H1, H2, S1, S2—it allows clinicians to make informed decisions about treatment, ensuring that gastric and duodenal ulcers are monitored effectively until complete healing is achieved. sakitamiwa classification
The Sakita-Miwa system provides a standardized language that ensures consistent care, regardless of the treating physician. By providing a clear, visual framework ( The defect is significantly smaller than in H1,

The core architecture of the Sakita-Miwa classification relies on a highly scannable, logical progression of tissue repair. Each of the three main stages is split into two sub-stages (1 and 2) to pinpoint the exact state of the wound.
While originally established for upper gastrointestinal (GI) tract pathology, the utility of the Sakita-Miwa scale has expanded seamlessly into evaluating lower intestinal ulcers, post-endoscopic resections, and localized inflammatory diseases. Understanding this grading metric is essential for gastroenterologists worldwide to accurately differentiate acute, high-risk ulcerations from benign, healing tissue. Structural Breakdown of the Sakita-Miwa Classification
: The necrotic slough covering the ulcer base drastically reduces in surface area. Regenerative epithelium begins migrating inward from the ulcer margins. Blood vessels become visible near the edge, delivering crucial oxygenation for granulation tissue development.
