Portal hypertensive polyposis is a rare finding represented in about 2.5% of all patients with portal hypertension. The diagnostic criteria are not yet clearly defined. It has been mentioned in a few case reports; its distribution was mainly duodenal and less frequently gastric. Here, a patient with type 2 diabetes and liver cirrhosis was hospitalized for vomiting, abdominal pain, and melena. The patient was admitted to the intensive care unit for stabilization and urgent esophagogastroduodenoscopy (EGD). EGD revealed a single antral polyp occluding the pyloric ring which was the cause of gastric outlet obstruction. Complete debulking by argon plasma was done which improved gastric outlet obstruction and melena. We conclude that argon plasma coagulation is a safe, rapid, and effective method for treating portal hypertensive polyposis.

门脉高压性息肉的管理：罕见实体的病例报告。

门脉高压性息肉病是罕见的发现，约占所有门静脉高压症患者的2.5％。诊断标准尚未明确定义。在一些案例报告中已经提到了它。其分布主要是十二指肠，较少见于胃。在这里，患有2型糖尿病和肝硬化的患者因呕吐，腹痛和黑便住院。该患者入院接受重症监护病房的稳定和紧急食管胃十二指肠镜检查（EGD）。EGD显示单个胃窦息肉闭塞了幽门环，这是胃出口阻塞的原因。通过氩气等离子体完成了完全减薄，从而改善了胃出口梗阻和黑便。我们得出结论，氩血浆凝结是一种治疗门脉高压性息肉病的安全，快速，有效的方法。
