目的 :探讨胃Dieulafoy病的内镜诊断和治疗方法。方法 :回顾性分析作者自 1994年 1月～ 2 0 0 2年 6月经内镜诊断和治疗胃Dieulafoy病的临床资料。结果 :12例均在入院后 2h之内行急诊内镜检查 ,经一次检查确诊 10例 ,二次检查确诊 2例。经内镜局部喷洒 0 .1%去甲肾上腺素治疗博动性出血 3例 ,仅 1例暂时止血约 12h后再出血。电凝治疗 11例均止血成功。结论 :急诊内镜是诊断胃Dieulafoy病的最佳手段 ,浅表溃烂伴博动性或喷射状出血是内镜诊断的主要依据 ,单独的暗红色血痂或黑褐小隆起是内镜诊断的重要线索。经内镜局部喷洒止血药疗效不佳 ,电凝是治疗该病的有效手段 Objective: To investigate the endoscopic diagnosis and treatment of gastric Dieulafoy disease. Methods: A retrospective analysis of the author from January 1994 to June 2002 endoscopic diagnosis and treatment of gastric Dieulafoy disease clinical data. Results: All the 12 cases underwent emergency endoscopy within 2h after admission. Ten cases were diagnosed by one examination and two cases were diagnosed by two examinations. Endoscopic partial spraying of 0.1% norepinephrine treatment of bleeding in 3 cases, only 1 case of temporary bleeding after about 12h and then bleeding. Electrocoagulation treatment of 11 cases were successful hemostasis. Conclusions: Emergency endoscopy is the best method to diagnose gastric Dieulafoy disease. Superficial ulceration with arterial or jet-like bleeding is the main basis of endoscopic diagnosis. The separate dark red blood scab or dark brown microrubes is endoscopic diagnosis Important clue Local endoscopic spray hemostatic effect is poor, coagulation is an effective means of treatment of the disease
