Which grade of reflux esophagitis—A, B, C, or D—is more severe?
In general, grade D of reflux esophagitis in the ABCD classification is considered more severe. The specific analysis is as follows:
In clinical medicine, reflux esophagitis is classified into four grades—A, B, C, and D—according to pathological staging. Grade A refers to one or more mucosal breaks within the stomach that are no longer than 5 mm and do not extend between the tops of two mucosal folds. Grade B refers to one or more mucosal breaks longer than 5 mm that do not extend between the tops of two mucosal folds. Grade C refers to one or more mucosal breaks that extend continuously between the tops of two or more mucosal folds but involve less than 75% of the esophageal circumference. Grade D refers to one or more mucosal breaks involving more than 75% of the esophageal circumference; therefore, grade D is considered more severe. Patients may follow medical advice to use medications such as esomeprazole magnesium enteric-coated capsules or pantoprazole sodium for injection for treatment.
If patients experience any discomfort symptoms, they are advised to seek timely medical attention at a hospital to avoid delaying their treatment.
