title: [A Case of Gastritis Cystica Polyposa That Developed Early after Distal Gastrectomy].
abstract: We present a case of gastritis cystica polyposa (GCP) that developed early after laparoscopy-assisted distal gastrectomy with BillrothⅠreconstruction. GCP is a chronic inflammatory gastric mucosal lesion that emerges at an anastomotic site usually after a long post-gastrectomy period, which is mainly caused by constant chemical stimulation by duodenal juice. In addition, chronic mechanical stimulation caused by reflux or stasis of gastrointestinal contents may also trigger GCP. Surgeons should ensure a functional and physiologically patent anastomosis during surgery. Hypergastrinemia, caused by persistent Helicobacter pylori infection or continuing administration of proton pump inhibitors, may also contribute to the development of GCP, as GCP is a type of hyperplastic polyp. Therefore, appropriate postoperative follow-up, including pylorus eradication and avoidance of unnecessary administration of proton pump inhibitors, seems to be needed in order to prevent the development of GCP. In our case, many factors exhibited the multiplier effect, resulting in early development of GCP. As GCP also attracts much attention as a precancerous lesion, appropriate prevention and prompt treatment are required.
