十二指肠球部胃化生和Hp感染与胃窦部病变相关性研究

目的探讨十二指肠球部胃化生（ＤＧＭ）、Ｈｐ感染和胃窦部病变相关性，方法收集１２６例胃镜检查所见、组织病理学、Ｈｐ和胃泌酸量及胃内２４小时ｐＨ值的资料行对比研究。结果ＤＧＭ的发生率５２．３％，在反流性胃炎中６７．９％；粘膜糜烂中２０．７％；溃疡中４０．８５％，反流性胃炎与另二组差异显著（Ｐ＜０．００５）。在慢性非活动性炎症、慢性活动性炎症和胃粘膜上皮肠化生中分别为４１．１％、４５．９％和４１．８％，三组差异不显（Ｐ＞０．０５）。在轻、中和重度胃酸分泌亢进者中分别为２６．０％、６６．０％和１００％，各组间差异显著（Ｐ＜０．０５）。２４小时胃内ｐＨ＜４的时间在有、无ＤＧＭ组间无明显差异（Ｐ＞０．０５）。睡眠期间ｐＨ＞６的时间在２小时以上者ＤＧＭ明显多于无ＤＧＭ（Ｐ＜０．０５）。十二指肠球部和胃窦部Ｈｐ检出率为４１．２％和８０．９％。十二指肠球部Ｈｐ阳性者在胃窦部Ｈｐ（＋）占２７．１％；（＋＋）占８０．１％和（＋＋＋）占１００％，各组间差异显著（Ｐ＜０．０５）。结论ＤＵ患者的ＤＧＭ发生率与胃窦部的反流性胃炎、胃酸分泌亢进和Ｈｐ感染等病有相关性。

Antral web associated with distal antral hypertrophy and prepyloric stenosis mimicking hypertropic pyloric stenosis

A 3-year-old boy presented with postprandial vomiting and epigastric pain for 3 wk. Barium meal study suggested hypertrophic pyloric stenosis. Ultrasound of the stomach after water loading revealed an echogenic antral web with an eccentric aperture and distal antral hypertrophy.Subsequent endoscopy confirmed the ultrasound findings.Web resection and antropyloroplasty resulted in excellent recovery. To our knowledge, the barium meal and ultrasound findings of an antral web-associated distal antral hypertrophy and prepyloric stenosis has not previously been described.
