Clinical Report: Sakita-Miwa Classification for Gastric Ulcers 📋 Executive Summary

: The floor is completely covered by regenerating epithelium, and the white coating has disappeared. It appears as a "red scar" due to visible capillaries. S2 (White Scar)

The classification system follows a numerical scoring or staging method to assess how well an ulcer is recovering: Active Stage (A1 & A2) A1 (Active-1)

: The redness fades over several months. The area turns into a pale, white, flat scar indistinguishable from normal mucosa except for its lack of normal gastric folds. 📊 Summary Table of Stages Core Endoscopic Appearance Active (A) A1

: Gastroenterologists use the scale to measure how well an ulcer is responding to proton pump inhibitors (PPIs) or potassium-competitive acid blockers (P-CABs). Complete cure is typically defined when an ulcer successfully reaches the S1 or S2 stage. sakitamiwa classification

In a Western clinic, a patient presenting with Sakitamiwa might be diagnosed with viral gastroenteritis, influenza, or psychosomatic pain. However, the Sakitamiwa classification provides a specific cultural narrative for why the illness occurred.

The Sakita-Miwa system provides a standardized language that ensures consistent care, regardless of the treating physician. By providing a clear, visual framework (

In the Sakitamiwa classification, antibiotics are secondary. The primary treatment involves the "healer" or elder facilitating a ritual to reverse the spiritual transgression. The success of this treatment reinforces the validity of the classification within the community.

A regenerating epithelium begins to form at the edges, and the white coating at the base starts to thin and shrink. The area turns into a pale, white, flat

It appears to be either:

Vascular malformations

While the Sakita-Miwa classification is specialized for documenting the healing process, other systems are also used in practice.

The for moving between stages (e.g., A1 to H1). In a Western clinic, a patient presenting with

The is a universally recognized medical framework used primarily by gastroenterologists to evaluate, stage, and monitor the healing lifecycle of gastric ulcers . Developed in Japan by researchers Sakita and Miwa, this staging system divides the progression of a peptic or gastric ulcer into six distinct phases nested within three major clinical periods: Active (A), Healing (H), and Scarring (S) .

If used as a syndrome or condition in a story:

This classification system provides a standardized, objective framework for monitoring the progression of gastric and duodenal ulcers from their initial, active phase through healing and finally to scarring. What is the Sakita-Miwa Classification?
