杭州胃十二指肠溃疡大出血【杭州城东医院】十二指肠溃疡的主要临床表现为上腹部疼痛，可为钝痛、灼痛、胀痛或剧痛，也可表现为仅在饥饿时隐痛不适。典型者表现为轻度或中度剑突下持续性疼痛，可被制酸剂或进食缓解。临床上约有2/3的疼痛呈节律性：早餐后1～3小时开始出现上腹痛，如不服药或进食则要持续至午餐后才缓解。食后2～4小时又痛，也须进餐来缓解。约半数患者有午夜痛，病人常可痛醒。节律性疼痛大多持续几周，随着缓解数月，可反复发生。

以下是十二指肠溃疡大出血的原因：
1、十二指肠溃疡基底部或边缘动脉受侵蚀、破裂，易大出血。如十二指肠球部溃疡常导致十二指肠动脉破裂；球后溃疡是侵蚀胰十二指肠动脉而造成致命性大出血。
2、溃疡基底部含有极丰富的肉芽组织，其中的血管受侵蚀、摩擦、溃破时易导致大出血。
3、溃疡周围充血的血管易损伤破裂而引起出血，偶有大出血。
4、巨大十二指肠溃疡（直径≥2厘米）易并发出血。有人报道32例，年龄为30—81岁（平均59岁），均为男性，75%的病人以大出血就诊，9%以游离穿孔就诊。
