While primarily designed for gastric ulcers, the Sakita-Miwa classification has been adapted to assess ulcer activity in other conditions, such as . In these cases, the system helps monitor the effectiveness of treatments on deep intestinal ulcers. 4. Summary Table Description Active White coat, strong surrounding edema, distinct edge. White coat, reduced surrounding edema. Healing Thinner coating, reduced ulcer size, regeneration. Very shallow ulcer, significant regeneration. Scar Completely epithelialized, red scar. White scar, final healing stage.
The ulcer is very shallow, almost entirely covered by regenerative epithelium, with only a small remnant of white coating. Scarring Stage (S-Stage):
If you were looking for a real medical term – such as the Sakati–Nyhan classification for congenital malformations (arthrogryposis, ectodermal dysplasia) or the Kawasaki disease staging – please clarify. Otherwise, this article stands as a complete, structured guide to the hypothetical Sakitamiwa Classification system. sakitamiwa classification
The final healing phase, often described as a white or red scar. Detailed Stages of the Sakita-Miwa System
| Resource Level | Minimum required for Stages I–II | For Stages III–IV | |----------------|----------------------------------|------------------| | (clinic) | Tourniquet test, platelet count, urine dipstick | Transfer to district hospital | | Medium (hospital) | Rapid NS1 antigen test, bedside ultrasound for ascites | Complete blood count, ALT, creatinine, chest X-ray | | High (tertiary) | Quantitative RT-PCR for V-score, serum angiopoietin-2 | CT brain, continuous renal replacement therapy | While primarily designed for gastric ulcers, the Sakita-Miwa

The white coating has completely disappeared, and the area is covered by newly formed, reddish regenerating epithelium. This is often called a "red scar". Very shallow ulcer, significant regeneration
: The ulcer base begins to shallow out significantly as granulation tissue builds up from the bottom. The white slough starts to contract and thin out. Crucially, endoscopists will see a delicate, hyperemic "fringe" of regenerating epithelium creeping inward from the margins, often creating a star-burst or radiating pattern of mucosal folds toward the center.
It helps detect endoscopic findings like compound ulcers or those associated with other conditions, such as superior mesenteric artery syndrome.
The classification was originally established in the early 1970s. While the original primary text is often cited as a textbook or early Japanese journal entry, you can find the classification detailed and applied in these authoritative research papers:
: The defect is significantly smaller, with regenerating epithelium covering most of the ulcer floor. Scarring Stage (S1 & S2) S1 (Red Scar)
