Gastric polyps are considered to be rare. However, at endoscopy the prevalence of gastric polyps after partial gastrectomy was found to be 8.9% (30/336 patients) compared with 4.9% (20/407) in a clinical control material with a comparable age and sex distribution. Four patients with precancerous mucosal alterations were found in the operated group. Repeated endoscopic check-ups have at present been performed in 57.4% of these patients. In our experience the diagnostic accuracy with regard to malignancy is not entirely satisfactory. Histological examination of the surgical specimen from one of the 4 patients with precancerous changes showed a macroscopically invisible early carcinoma. Follow-up examinations (within 4 years) have in 5 out of 26 cases with sessile polyps disclosed carcinoma in 3 cases and precancerous changes or adenoma in another 2 cases. Careful re-examination of all patients with precancerous changes and gastric polyps is recommended.
胃息肉被认为较为罕见。然而，在内镜检查中发现，部分胃切除术后胃息肉的患病率为8.9%（336例患者中有30例），而年龄和性别分布可比的临床对照材料中的患病率为4.9%（407例中有20例）。手术组中发现4例有癌前黏膜改变的患者。目前，这些患者中有57.4%接受了重复内镜检查。根据我们的经验，关于恶性肿瘤的诊断准确性并不完全令人满意。对4例有癌前改变的患者之一的手术标本进行组织学检查，发现了肉眼不可见的早期癌。在26例有蒂息肉病例中，有5例进行了随访检查（4年内），其中3例发现癌变，另外2例发现癌前改变或腺瘤。建议对所有有癌前改变和胃息肉的患者进行仔细复查。
