The Sakita-Miwa classification is a standard endoscopic staging system used to evaluate the healing process of gastric and duodenal ulcers. It divides ulcer progression into three main stages (Active, Healing, and Scarring), with each further subdivided into two levels. Classification Stages The system uses the following six-stage categorical scale: Stage Description A1 Acute phase; thick white coating (slough) and sharp edges. A2
The ulcer has disappeared, replaced by a red scar consisting of young, delicate tissue. S2 (Scarring 2/White Scar): sakitamiwa classification
Slough becomes thinner; edema at the margin begins to decrease; the ulcer base is clearly demarcated . Healing (H) H1 Patients with Sak-A had a 5-year survival rate
This system is frequently used in clinical research, such as Randomized Clinical Trials, to evaluate the effectiveness of Proton Pump Inhibitors (PPIs) or other ulcer-healing medications. such as Randomized Clinical Trials
Recommendations
: The white coating thins, and regenerating epithelium extends into the ulcer base. The ulcer crater is still visible but smaller. H2 (Healing-2)
