一、返流性食管炎 多因酸性胃内容物返流入食管所致的食管粘膜炎症。 [诊断要点] (一) 临床表现 多有上腹部或胸骨后烧灼感或疼痛,多于餐后平卧或腹内压增加时出现,服制酸药可缓解。重症可出现吞咽困难及呕吐或出血。 (二) X线检查 食管粘膜皱襞粗乱,蠕动变弱。增加腹内压可见返流现象(50％)。 (三) 食管内压力测定 正常食管下段括约肌压力1.466～1.999kPa(11～15mmHg),本病时可低于0.7998kPa(6mmHg)。
First, reflux esophagitis due to acidic gastric contents reflux esophageal mucosal inflammation caused by the esophagus. [Diagnostic points] (A) clinical manifestations and more after the upper abdomen or sternal burning sensation or pain, more than after supine or intra-abdominal pressure increases, serving acid can be alleviated. Severe swallowing difficulties may occur and vomiting or bleeding. (B) X-ray examination of esophageal mucosa folds rough, peristalsis weakened. Increased intra-abdominal pressure can be seen reflux (50%). (C) of the esophageal pressure to determine the normal lower esophageal sphincter pressure 1.466 ~ 1.999kPa (11 ~ 15mmHg), the disease can be less than 0.7998kPa (6mmHg).
