Sakitamiwa Classification ((new)) Now

The Sakita-Miwa system classifies ulcers into three main phases, which are further divided into sub-stages to create a precise six-stage continuum ( A1cap A sub 1 A2cap A sub 2 H1cap H sub 1 H2cap H sub 2 S1cap S sub 1 S2cap S sub 2 A-Stage (Active Stage) The Active Stage indicates a fresh, inflammatory ulcer. A1cap A sub 1

This final phase signifies the completion of the healing process. The ulcer is now closed, and the newly formed tissue is undergoing a maturation process.

The system organizes the ulcer healing process into three main phases: , Healing (H) , and Scarring (S) . Each of these phases is further divided into two substages, creating a standardized staging system of A1, A2, H1, H2, S1, and S2, which form the basis for the Sakita-Miwa Classification.

: 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) The Sakita-Miwa system classifies ulcers into three main

: 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.

Sakita-Miwa Classification is a widely used endoscopic system for staging the healing process of peptic ulcers (gastric and duodenal). It categorizes ulcers into three main stages—Active, Healing, and Scarring—each with two sub-stages. 1. Active Stage (A)

The ulcer is still active, but the edema around the margins begins to decrease. The white coat (exudate) is still present, but the ulcer depth might begin to decrease slightly compared to A1. 2. Healing Stage (H) For medical advice or diagnosis, consult a professional

The is a globally recognized endoscopic grading system used to evaluate the life cycle and healing stages of peptic (specifically gastric) ulcers. Developed in Japan, it provides clinicians with a standardized framework to assess whether an ulcer is in an active, healing, or scarring phase. This classification directly informs treatment efficacy and determines the duration of acid-suppressive therapy. 🔬 Classification Breakdown

This is the initial phase when the ulcer is actively inflamed and causing the most severe symptoms for the patient. The division between A1 and A2 reflects the earliest signs of the body's healing efforts.

In research settings, these stages are often converted into numerical "healing scores" to track progress: ScienceDirect.com Healing Score (Standard) Description Acute active ulcer Resolving active ulcer Early healing Advanced healing Red scar (Cured) White scar (Cured) Note: Some studies use a reversed 6-point scale (A1=6, S2=1) depending on the specific trial protocol.
