胃息肉的临床病理特征和内镜治疗随访观察

背景：胃息肉是一种常见病，病因不明且有癌变的可能。目的：分析胃息肉的临床、内镜、病理特征和内镜治疗效果。方法：对2006年7月1日～2009年7月1日于空军总医院接受胃镜检查，诊断为增生性息肉、腺瘤性息肉和胃底腺息肉的患者进行回顾性分析。结果：共检出三种常见类型的胃息肉392例，检出率为3.4％，单发283例，多发109例。61．5％的患者位于30～59岁年龄段．53．1％的患者息肉形态为山田Ⅱ型，64．0％的患者息肉最大径≤0．5cm。365例行病理检查者中，增生性、腺瘤性和胃底腺息肉分别占63．6％、5．5％和31．0％，前两者好发于胃窦部，后者好发于胃体、胃底部。383例患者成功接受内镜治疗。75例有随访资料者中20例复发，其中13例为多发息肉。结论：胃息肉内镜下多为山田Ⅱ型，直径较小，多为单发．病理类型上以增生性息肉和胃底腺息肉多见。多发息肉治疗后易复发。

Clinicopathologic Characteristics,Endoscopic Therapy and Follow-up Study of Gastric Polyps

Background： Gastric polyp is a common disease with unknown etiology and has the potential of malignant transformation. Aims： To analyze the clinical, endoscopic and pathological characteristics, and the efficacy of endoscopic therapy of gastric polyps. Methods： Patients undergoing gastroscopy and diagnosed as having hyperplastic polyp, adenomatous polyp or fundic gland polyp in the Air Force General Hospital from July 1, 2006 to July 1, 2009 were recruited in this study and analyzed retrospectively. Results： Three hundred and ninety-two patients were diagnosed as having these three most common types of gastric polyp with a detection rate of 3.4%. Two hundred and eighty-three cases were single polyp and 109 cases were muhiple ones. 61.5% of the patients aged from 30 to 59 years old. The polyps in 53.1% of the patients were Yamata type Ⅱ, and the maximal diameter of polyps in 64.0% of the patients were equivalent to or smaller than 0.5 cm. Pathological examinations were performed in 365 patients, the percentage of hyperplastic polyp, adenomatous polyp and fundic gland polyp was 63.6%, 5.5% and 31.0%, respectively. The fundic gland polyps located predominantly at the corpus and fundus, while the other two types of polyps mainly located at the antrum. Three hundred and eighty-three patients had their polyps removed under gastroscopy successfully. In 75 followed-up patients, 20 had recurrence, among which 13 were multiple polyps. Conclusions： Yamata type Ⅱ, small and single polyps are most common polyps detected under gastroscopy. Hyperplastic polyp and fundic gland polyp are the two main types diagnosed pathologically. Multiple polyps are likely to recur after endoscopic removal.
