BACKGROUND
Endoscopic submucosal dissection (ESD) is the treatment of choice for early gastric cancer and premalignant gastric dysplasia. In some cases, ESD induced ulcer heals as a polypoid nodular scar (PNS). These scars may make the physicians raise several clinical implications such as post-ESD neoplastic recurrence.
CASE SUMMARY
We described a case of gastric ESD induced PNS which is regressed after eradication. A 58-year-old male patient was referred to the outpatient clinic for evaluation and treatment of gastric low-grade dysplasia (LGD). ESD was performed. A PNS was developed at the ESD site. An endoscopic biopsy was done and there was no histological evidence of remnant tumor or recurrence but a hyperplastic mucosal change. The PNS showed increase in size in follow-up endoscopy, and the biopsy specimen demonstrated infestation. eradication was done and the PNS was regressed.
CONCLUSION
eradication is considerable for the regression of PNS if infestation is confirmed.
背景
内镜下黏膜剥离术（ESD）是早期胃癌和癌前胃发育异常的首选治疗方法。在某些情况下，ESD引起的溃疡愈合为息肉样结节性瘢痕（PNS）。这些瘢痕可能会使医生产生一些临床疑虑，如ESD后肿瘤复发。
病例摘要
我们描述了一例胃ESD引起的PNS在根除后消退的病例。一名58岁男性患者因胃低度发育异常（LGD）前来门诊评估和治疗。进行了ESD。ESD部位出现了PNS。进行了内镜活检，没有残余肿瘤或复发的组织学证据，但有增生性黏膜改变。在随访内镜检查中，PNS大小增加，活检标本显示有感染。进行了根除治疗，PNS消退。
结论
如果确认有感染，根除治疗对于PNS的消退是值得考虑的。
