将发生于贲门部、胃底部及高位胃体部的癌肿统称为贲门周围癌。由于该区局部解剖和组织结构较复杂,临床表现变化多端,且早期多缺少明显自觉症状,使发生于该区的癌肿既不同于食管癌,又和胃癌有所区别,因此给临床、X线及胃镜检查均带来一定困难,故其误、漏诊率也较高。我们对贲门周围癌的误诊原因作一分析。临床资料:我们使用纤维胃镜共检出贲门周围癌150例,其中贲门癌49例,胃底癌16例,高位胃体癌85例。男118例,女32网,年龄28～79岁,病程20天～1年。150例中属胃镜检查前临床、X线误诊者98例,占65.3%。首次胃镜检查误诊5例,复诊证实3例。误诊时间最长者1年,最短20天。分别误诊为消化性淡疡、胃炎、贲门痉挛、食管炎及胃下垂等。
Cancers that occur in the cardia, the stomach, and the upper stomach are collectively referred to as cancer around the cardia. Due to the complexity of local anatomy and tissue structure in this area, the clinical manifestation changes frequently, and early stage lacks obvious subjective symptoms. This causes the occurrence of cancer in this area is not only different from esophageal cancer, but also differentiates from gastric cancer, so it gives clinical, X Line and gastroscopy have brought some difficulties, so their mistakes and missed diagnosis rate are also high. We analyzed the causes of misdiagnosis of cancer around the fontanelle. Clinical data: We used fiberoptic gastroscopy to detect 150 cases of cardiac cancer around the cardia, including 49 cases of cardiac cancer, 16 cases of gastric fundus, and 85 cases of high gastric cancer. 118 males, 32 females, ages 28 to 79 years, duration of 20 days to 1 year. Among the 150 cases, 98 cases were misdiagnosed before gastroscopy, which accounted for 65.3%. The first gastroscopy was misdiagnosed in 5 cases and the follow-up confirmed it in 3 cases. The longest misdiagnosis period is 1 year, the shortest 20 days. Misdiagnosed as peptic ulcer, gastritis, fistula, esophagitis and gastroptosis.
