Regenerated mucosal patterns that appeared during the healing of chronic gastric ulcers were observed and assessed in detail by magnifying endoscopes. Three patterns of ulcer scarring were distinguished: Sa with central depression, Sb with a coarse regenerated mucosal pattern, and Sc with a fine mucosal pattern. From a study on the relationship between the depth of ulcer confirmed histologically and the endoscopic findings of the scar, a clear distinction could be made endoscopically between U1-IV scar with a well-demarcated scarring zone, U1-III scar with an unclear boundary, and U1-II scar without a distinct scar area. Scar patterns were also related to ulcer depth. Analysis of the relationship between an ulcer relapse and the scar pattern demonstrated that the ulcer relapse rate over a 2-year follow-up period was 84% in Sa, 33% in Sb, and 0% in Sc.
通过放大内镜对慢性胃溃疡愈合过程中出现的再生黏膜形态进行了详细观察和评估。区分出三种溃疡瘢痕形态：中央凹陷的Sa型、再生黏膜形态粗糙的Sb型和黏膜形态精细的Sc型。通过一项关于组织学确诊的溃疡深度与瘢痕内镜表现之间关系的研究，在内镜下可以明确区分出瘢痕区界限清晰的U1-IV型瘢痕、边界不清晰的U1-III型瘢痕和无明显瘢痕区域的U1-II型瘢痕。瘢痕形态也与溃疡深度有关。对溃疡复发与瘢痕形态之间关系的分析表明，在2年的随访期内，Sa型溃疡的复发率为84%，Sb型为33%，Sc型为0%。
