The rate of blood transfusion is related to blood flow and the diameter of the bleeding vessel. Therapeutic endoscopy is less effective in larger vessels. To determine the effect of therapeutic endoscopy with pure ethanol injection in massive peptic ulcer bleeding, we conducted a retrospective study using the maximal one-day blood requirement as an indicator of the required blood transfusion.
The maximal one-day blood requirement was defined as the total amount of blood transfusion needed within a day to keep hemodynamics stable and hemoglobin above 8.0 g% before therapeutic endoscopy. From January 1986 to May 1993, 283 patients with high-risk signs of the stigmata of hemorrhage on endoscopy, who received pure ethanol injection therapy, were included in this study. There were 214 men and 69 women with a mean age of 58.4 years (ranging from 16 to 93 years). One hundred forty-three had gastric ulcers; 125 had duodenal ulcers; and 15 had stomal ulcers. Patients whose maximal one-day blood requirement was less than 1000 ml were assigned to Group I. Patients without, and patients with, major organ diseases whose maximal one-day blood requirement was more than 1000 ml were assigned to Group IIa and Group IIb, respectively.
In Group I, 87.1% attained permanent hemostasis; 51.3% in Group IIa; and 49.4% in Group IIb. Temporary hemostasis and failure rates were 8.9% and 4.8% in Group I; 14.5% and 33.8% in Group IIa; and 21.2% and 29.4% in Group IIb. The rate of permanent hemostasis was significantly lower in patients with massive bleeding (p < 0.001) but did not differ between patients with and without major organ diseases (p > 0.05).
The success rate for pure ethanol injection therapy was lower in patients with a large maximal one-day blood transfusion requirement.
输血速率与血流及出血血管直径相关。治疗性内镜检查对较大血管的疗效较差。为确定单纯乙醇注射治疗性内镜检查在大量消化性溃疡出血中的效果,我们进行了一项回顾性研究,将最大单日需血量作为所需输血的指标。
最大单日需血量定义为治疗性内镜检查前一天内为维持血流动力学稳定且血红蛋白高于8.0 g%所需的输血总量。1986年1月至1993年5月,本研究纳入了283例内镜检查有高危出血征象且接受单纯乙醇注射治疗的患者。其中男性214例,女性69例,平均年龄58.4岁(16至93岁)。胃溃疡143例;十二指肠溃疡125例;吻合口溃疡15例。最大单日需血量少于1000 ml的患者被分配到I组。最大单日需血量超过1000 ml且无主要器官疾病的患者和有主要器官疾病的患者分别被分配到IIa组和IIb组。
I组中,87.1%实现了永久性止血;IIa组为51.3%;IIb组为49.4%。I组的暂时性止血率和失败率分别为8.9%和4.8%;IIa组为14.5%和33.8%;IIb组为21.2%和29.4%。大量出血患者的永久性止血率显著较低(p < 0.001),但有和无主要器官疾病的患者之间无差异(p > 0.05)。
最大单日输血需求量大的患者,单纯乙醇注射治疗的成功率较低。
