Sakitamiwa Classification

Unlike linear systems (e.g., sepsis staging), the Sakitamiwa Classification integrates three pathognomonic axes:

Deep crater, heavy white/gray slough, intense surrounding edema Slough remains, but surrounding mucosal edema subsides Healing (H) H1

The Sakita-Miwa system divides ulcer lifecycle development into three progressive macro-stages, with each stage split into two distinct sub-categories (

This is the final stage where the ulcer has completely closed, leaving only a scar behind. ClinicalTrials.gov S1 (Scarring 1/Red Scar): sakitamiwa classification

Conversely, East Asian clinical workflows frequently employ both systems. While Forrest assists in acute emergency management, the Sakita-Miwa classification provides a chronological, high-resolution map of tissue architecture repair over weekly and monthly follow-ups.

: Over several months to years, the redness fades, and the scar becomes the same color as the surrounding mucosa, appearing as a white spot. Scoring System

Classification: A Shinto concept. One of the four souls (Mitama) in Kokugaku tradition. Represents blessing, joy, and mystical fortune. Often depicted as a gentle, light-emitting spirit.

If used as a syndrome or condition in a story: Unlike linear systems (e

The ulcer is very shallow and nearly covered by new tissue. The surrounding inflammation has largely disappeared. PubMed Central (PMC) (.gov) 3. Scarring Stage (S)

The white coating has completely disappeared, and new epithelium fully covers the floor. Because the new tissue is thin and has many blood vessels, it appears as a "red scar".

: The dense white slough coating on the floor becomes noticeably thin. Regenerating epithelium begins migrating from the margins, covering less than 50% of the original ulcer base. Converging mucosal folds can now be clearly seen traveling directly toward the edge of the ulcer crater.

The white coating has completely disappeared, leaving only a red scar (red scar stage). Applications in Modern Clinical Trials : Over several

During this stage, therapeutic interventions or natural bodily defenses begin to shrink the dimensions of the wound.

The framework tracks the quantitative and qualitative evolution of an ulcer's mucosal base, edge margin, and surrounding tissue. It effectively maps out how a raw, necrotic wound transitions into fully re-epithelialized tissue.

The Active Stage represents the acute phase of a peptic or iatrogenic ulcer.

The Sakita-Miwa system is highly regarded for its precision. It divides the healing process into six distinct categories: 1. Active Stage (A)
