: The ulcer becomes remarkably small and shallow. The white exudate coating is reduced to a tiny central speck or a very thin film. The surrounding regenerative epithelium covers the vast majority of the previous defect, and mucosal folds clearly converge directly toward the healing center. 3. The Scarring Stage (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 term "Sakitamiwa" itself is enigmatic, with various interpretations and speculations surrounding its meaning. Some believe it to be a name or a term derived from an ancient language, while others see it as an acronym or a code. sakitamiwa classification

The active phase represents the acute, fully formed ulceration where tissue loss is prominent and the risk of complications like upper gastrointestinal bleeding is elevated.

: The ulcer is sharply demarcated with a deep crater. The floor is covered heavily with a thick, white or yellowish-gray exudate (slough). The surrounding mucosal margin is swollen and edematous. : The ulcer becomes remarkably small and shallow

The swelling around the edges begins to subside, but the white coating remains thick and the ulcer crater is still very distinct. Healing Phase (H)

This is the final stage where the ulcer has effectively closed. The term "Sakitamiwa" itself is enigmatic, with various

– Possibly in fields like traditional medicine, botany, or library science in Japanese or another language.

The staging is based on three key visual characteristics observable during an endoscopy: the thickness of the "white coating" (slough or exudate) covering the ulcer, the extent to which new pink (regenerating) epithelium has grown over the ulcer base, and the color of the resulting scar.
