Sakitamiwa Classification [patched] -

Proposed by Sakita and Miwa, this classification system breaks down the ulcer life cycle into distinct stages based on endoscopic appearance. It is designed to track the morphological changes of the ulcer crater over time. The primary stages include: The acute phase of the ulcer. Healing (H1, H2): The phase where regeneration begins.

: The white coating becomes thin, and new epithelium significantly extends into the ulcer base. The ulcer crater is still visible, but its diameter is reduced to about one-half or two-thirds of the A1 size. sakitamiwa classification
