A Case of Early Gastric Remnant Cancer Treated by Endoscopic Mucosal Resection / 대한소화기내시경학회지

ABSTRACT

Patients who have undergone partial gastric resection are at an increased risk for the development of cancer and polyps in the gastric remnant, and this risk increases with time following gastrectomy. The prevalence of polypoid change at 15~20 years after surgery is approximately 10%, about four or five times higher as compared to nonoperated one. Hyperplastic polyps are encountered more frequently than adenomatous polyps. Surgical treatment for gastric remnant cancer has been regarded as standard method, but it was reported that endoscopic mucosal resection of early gastric remnant cancer could be performed under strict indication, as the incidence of lymph node metastasis was very low. Recently one adenomatous polyp with focally carcinoma in situ in the gastric remnant was removed by endoscopic mucosal resection in male patient who had undergone Billroth II gastrojejunostomy for gastric ulcer disease 12 years earlier.
