Sakitamiwa Classification -

This stage represents the acute phase of the ulcer where the mucosal defect is most prominent.

The (frequently searched as "sakitamiwa") is a critically acclaimed six-stage endoscopic grading system used primarily in East Asian clinical practice to evaluate, track, and stage the healing process of gastric and peptic ulcers. While Western gastroenterologists often rely on systems like the Forrest classification to assess active bleeding and rebleeding risks, the Sakita-Miwa system serves as the gold standard for tracking chronological tissue repair, from acute breakdown to complete mucosal scarring.

The goal of any lesion classification is to group entities by shared origin, morphology, natural history, and treatment implications. The Sakitamiwa classification (hypothetical name used here) divides congenital cutaneous and soft-tissue anomalies into four principal categories: Vascular malformations, Vascular tumors, Hamartomas/overgrowth syndromes, and Developmental epidermal/dermal defects. This structure aids clinicians in diagnosis, prognosis, and selecting therapy.

: The white exudate has completely disappeared. The ulcer is replaced by a flat, red, regenerating mucosal scar, often radiating outward in a star-like pattern. The Sakita-Miwa classification is a widely used endoscopic

: During this transitional active phase, inflammation begins to calm. The surrounding tissue edema shrinks, rendering the "lip-like sign" barely visible or absent. The base remains covered in mucus/slough, but the boundaries are sharper. 2. The Healing Stage (Stage H)

This represents the acute phase of mucosal injury where the ulcer crater is fully formed, necrotic, and susceptible to complications like hemorrhage.

The Sakita-Miwa classification is a fundamental endoscopic tool used in gastroenterology to categorize the life cycle of a gastric ulcer. Established by Japanese researchers Sakita and Miwa, this system provides a standardized language for clinicians to describe whether an ulcer is in an active state, a healing state, or a scarring state. By breaking down the healing process into six distinct stages, it allows doctors to monitor patient progress, evaluate the effectiveness of treatments, and predict the risk of recurrence or complications. Structure of the Classification

The ulcer begins to shrink. The white coating becomes thinner, and regenerating epithelium (new skin) starts to extend into the base. Mucosal folds may begin to converge toward the ulcer margin. H2 (Healing-2):
