Abstract
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 Helicobacter pylori (H. pylori) 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 H. pylori infestation. H. pylori eradication was done and the PNS was regressed.

CONCLUSION

H. pylori eradication is considerable for the regression of PNS if H. pylori infestation is confirmed.
