: The ulcer base is deeply cratered and heavily covered with a thick, white or yellowish-gray necrotic slough (exudate). The margins of the ulcer are sharply defined and severely swollen with prominent edema. Blood clots or exposed vessel stubs may be visibly protruding from the bottom.
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. sakitamiwa classification
Understanding the Sakita-Miwa Classification for Peptic Ulcers : The ulcer base is deeply cratered and
The ulcer has a white, deep base with sharp, surrounding inflammation. The is the globally recognized endoscopic staging system
The Sakita-Miwa classification is not merely academic; it has direct clinical applications:
: Swelling decreases, and the ulcer margin becomes clear. A small amount of regenerating epithelium may appear at the edges, often accompanied by a red "halo" or white "circle" around the margin. Healing Stage (H)
