Gastric polyps are rare. Most patients either are asymptomatic or present with symptoms of vague epigastric pain and bloating. An upper gastrointestinal tract study can demonstrate gastric polyps in 85 to 90 per cent of the patients. Features that increase the suspicion of carcinoma include the presence of adenomatous polyps greater than 2 centimeters in diameter, especially if they are multiple. In most patients, gastrotomy and removal of the polypoid mass with a cuff of normal mucosa are sufficient treatment. In patients who have invasive adenocarcinoma found upon biopsy of the polyp, gastric resection should be done. In most patients with carcinoma in situ, wedge resection is adequate treatment. Endoscopy for the diagnosis and treatment of polyps is appropriate in selected patients with pedunculated polyps that are less than 2 centimeters in diameter. The morbidity after operation or endoscopy is similar. Patients who are at high risk of having carcinoma develop should be observed yearly by endoscopic examination and biopsy.
胃息肉较为罕见。大多数患者要么无症状，要么表现为上腹部隐痛和腹胀等症状。上消化道检查可在85%至90%的患者中发现胃息肉。增加癌变怀疑的特征包括直径大于2厘米的腺瘤性息肉，尤其是多发性的。对大多数患者而言，胃切开术并切除带有一圈正常黏膜的息肉样肿物是足够的治疗方法。对于息肉活检发现有浸润性腺癌的患者，应进行胃切除术。对于大多数原位癌患者，楔形切除术是足够的治疗方法。对于直径小于2厘米的有蒂息肉的特定患者，采用内镜检查来诊断和治疗息肉是合适的。手术或内镜检查后的发病率相似。有癌变高风险的患者应每年接受内镜检查和活检。
