The is a standardized categorical system used primarily to grade the severity, progression, or morphological characteristics of a specific disease process. Unlike general diagnostic scales (such as the TNM system for cancer), the Sakitamiwa system is known for its high specificity, often incorporating histopathological, immunohistochemical, and sometimes genetic markers into a unified scoring framework.
This classification system separates the healing journey into three main phases, further broken down into sub-stages to provide a detailed roadmap of recovery. The 3 Stages of the Sakita-Miwa Classification sakitamiwa classification
The edema at the ulcer margin begins to subside, and the "lip-like sign" is less prominent. The ulcer base remains covered with slough. 2. Healing Stage (Stage H) The is a standardized categorical system used primarily
The ulcer is at its peak. The surrounding mucosa (lining) is swollen and red, and the ulcer floor is covered with a thick "white coating" (slough). The 3 Stages of the Sakita-Miwa Classification The
Clinical Report: Sakita-Miwa Classification for Gastric Ulcers 📋 Executive Summary
Unlike linear systems (e.g., sepsis staging), the Sakitamiwa Classification integrates three pathognomonic axes:
The ulcer crater is still visible, but the margins become sharper and the diameter of the defect shrinks to about half or two-thirds of the A1 stage. Regenerating epithelium (new skin) starts appearing at the edges.
