Sakitamiwa Classification //free\\ -

It is important not to confuse the Sakita-Miwa classification with another common endoscopic scoring system for ulcers: the .

The is a universally recognized medical framework used primarily by gastroenterologists to evaluate, stage, and monitor the healing lifecycle of gastric ulcers . Developed in Japan by researchers Sakita and Miwa, this staging system divides the progression of a peptic or gastric ulcer into six distinct phases nested within three major clinical periods: Active (A), Healing (H), and Scarring (S) .

This is the most acute phase. The ulcer is characterized by a thick, white slough (exudate) covering the base. The margins are sharp and swollen (edematous), and there are no visible mucosal folds reaching the ulcer. A2 (Active-2):

The red scar has matured into a white scar, indicating the final stage of the healing process. 2. Clinical Significance and Application It is important not to confuse the Sakita-Miwa

: The healing accelerates. The central white patch shrinks significantly, turning into a tiny island surrounded by a dominant, concentric ring of fresh red tissue. 3. The Scarring Stage (Stage S)

The is a widely accepted endoscopic staging system used to assess the healing process of peptic ulcers, particularly gastric ulcers. Developed to provide a standardized, objective language for endoscopists, this system plays a crucial role in clinical practice and research for tracking ulcer progression from active inflammation to scar formation.

: The ulcer defect is much smaller than H1. Regenerating epithelium covers most of the floor, and the white coating occupies only about a quarter to one-third of the original A1 area. Scarring Stage (S) S1 (Red Scar)
