The Sakita-Miwa classification is heavily used in clinical trials and day-to-day practice in Japan and other East Asian countries to:

The classification of Sakitamiwa is not universally agreed upon, and different cultural contexts have their own understanding of the condition. However, based on available literature and research, Sakitamiwa can be broadly classified into the following categories:

The white coating has completely disappeared. The ulcer base is fully covered by new epithelium, but the area remains markedly red due to new capillary growth. S2 (Scar-2 or White Scar): sakitamiwa classification

This phase is characterized by the active regrowth of new tissue (regenerating epithelium) over the ulcer crater. The progression from H1 to H2 shows the ongoing reduction in the size of the ulcer defect.

This classification is a critical tool in clinical trials to evaluate the efficacy of acid-suppressing drugs like Proton Pump Inhibitors (PPIs) and Potassium-Competitive Acid Blockers (P-CABs) .

The white coating completely disappears; the entire base is covered by newly formed, highly vascularized red epithelium. This is for informational purposes only

The system organizes the ulcer healing process into three main phases: , Healing (H) , and Scarring (S) . Each of these phases is further divided into two substages, creating a standardized staging system of A1, A2, H1, H2, S1, and S2, which form the basis for the Sakita-Miwa Classification.

Thinning of the white exudative coating; a clear zone of red, regenerating epithelium begins to creep inward from the ulcer margins.

The active phase denotes the acute development of the ulcer, characterized by a distinct slough or sloughing layer covering the ulcer base. Learn more The Sakita-Miwa classification is heavily used

💡 Doctors use this system to determine if a treatment—like proton pump inhibitors (PPIs) —is working. An ulcer is medically considered "cured" once it reaches the S1 or S2 stage.

The is the globally recognized endoscopic staging system used by gastroenterologists to evaluate the lifecycle and healing progression of peptic ulcers . First proposed by Japanese researchers Sakita and Miwa in 1971, this classification system translates the complex, continuous biological process of mucosal wound healing into structured categorical data.
