Sakitamiwa Classification ^hot^ [720p — HD]

The ulcer is deep with a thick, white or yellowish-gray coating (slough) at the base. The margins are sharp and often swollen with edema.

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 edema at the ulcer margin begins to subside, and the ulcer base appears cleaner. The white coating may begin to thin. 2. Healing Stage (H1 & H2) sakitamiwa classification

In modern research, doctors often assign numerical scores to these stages to quantitatively measure improvement. For example, a study on ischemic colitis or Behçet’s disease might use the following scale: Clinical Meaning Numerical Score (Example) Highly Active / Deep A2 Active / Slightly Improved H1 Early Healing H2 Advanced Healing S1 Red Scar (Healed) S2 White Scar (Mature) Why is this Classification Important?

In this stage, the ulcer is "active" and often associated with the highest risk of complications like bleeding. The ulcer is deep with a thick, white

The is a standardized endoscopic grading system used primarily by gastroenterologists to assess the life cycle and healing stages of peptic ulcers (both gastric and duodenal). Developed by Japanese researchers Sakita and Miwa, it divides the progression of an ulcer into three main stages— Active (A) , Healing (H) , and Scarring (S) —each further subdivided into two substages.

The ulcer becomes shallower as granulation tissue fills the base. Regenerating epithelium (new skin) begins to creep in from the edges, often creating a "palisade" appearance of mucosal folds. The edema at the ulcer margin begins to

At this point, the ulcer is considered "endoscopically cured" because the mucosal defect has vanished.
