Sakitamiwa Classification Jun 2026

: The regenerating epithelium completely covers the ulcer floor, and the white coating has disappeared. The area appears markedly red due to many visible capillaries. S2 (White Scar)

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. sakitamiwa classification

: The ulcer crater and its white slough are entirely gone. The site is replaced by a flat plane of regenerating epithelium. Because this new tissue is highly vascularized, it displays a distinct hyperemic red color under the endoscope's light. : The regenerating epithelium completely covers the ulcer

This group includes children where the tuberculosis bacteria are primarily located in the lungs and thoracic cavity. It is designed to track the morphological changes
