Sakitamiwa: Classification !new!

The scarring stage represents clinical cure, where the open wound is closed and completely re-epithelialized.

The is a widely used system in gastroenterology for staging the progression and healing of gastric and duodenal ulcers . First described by Sakita and Miwa, this classification helps clinicians determine whether an ulcer is in an active, healing, or scarring phase based on its endoscopic appearance. The Six Stages of Sakita-Miwa Classification

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. sakitamiwa classification

Mature healing; the red scar fades to a stable, pale white scar 💡 Clinical Significance and Application

The application process involves a multi-step diagnostic workflow: The scarring stage represents clinical cure, where the

The Sakita–Miwa classification system splits the lifecycle of an ulcer into three major chronological steps, with each phase further sub-divided into two precise micro-stages.

The ulcer base is completely covered by new epithelium, but the area remains red and vascularized. This is a "fresh" scar. The Six Stages of Sakita-Miwa Classification The staging

The is a standardized medical staging system used primarily in East Asian clinical practice to evaluate the healing process of gastric and duodenal ulcers. It breaks down the "life cycle" of an ulcer into six distinct stages categorized under three main phases: Active, Healing, and Scarring. Active Phase (A)

Sakita–Miwa classification is a standard endoscopic tool used to stage the life cycle and healing progress of gastric ulcers. It categorizes ulcers into three main stages—Active, Healing, and Scarring—each subdivided into two substages. PubMed Central (PMC) (.gov) The 6 Stages of Sakita–Miwa

The Sakita-Miwa classification is essential for several reasons:
