Rebleeding following epinephrine injection of bleeding peptic ulcers occurs in 10% to 20% of all cases. The addition of a sclerosant has the theoretical advantage of inducing vessel thrombosis and permanent hemostasis.
A prospective randomized controlled trial was conducted to compare injections with epinephrine alone or epinephrine plus absolute alcohol in patients with actively bleeding ulcers at endoscopy. Repeat endoscopy was performed 24 hours later; treatment was repeated in the presence of endoscopic signs of rebleeding. Surgery was performed when arterial bleeding could not be controlled endoscopically, clinical rebleeding with hematemesis or shock occurred, or the transfusion total exceeded 8 units.
One hundred sixty patients were enrolled (epinephrine alone, 81; epinephrine and absolute alcohol, 79). They were matched in age, sex, location of ulcers, hemoglobin on admission, shock, and severity of bleeding. Initial hemostasis was comparable: 79 of 81 with epinephrine alone (97.5%) versus 75 of 79 with epinephrine and absolute alcohol (94.9%). No difference was observed between the two with respect to either rebleeding (9 vs 6), need for emergency operation (12 vs 9), transfusion requirement (median, three units vs two units), hospital stay (median, 5 days vs 4 days), mortality (4 vs 7) and ulcer healing at 4 weeks (50 vs 46).
The additional injection of absolute alcohol after endoscopic epinephrine injection confers no advantage.
肾上腺素注射治疗出血性消化性溃疡后再出血的发生率在所有病例中为10%至20%。添加硬化剂在理论上具有诱导血管血栓形成和实现永久性止血的优势。
进行了一项前瞻性随机对照试验,以比较在内镜检查时对活动性出血溃疡患者单独注射肾上腺素或注射肾上腺素加无水酒精的效果。24小时后进行重复内镜检查;在内镜下有再出血迹象时重复治疗。当内镜无法控制动脉出血、发生呕血或休克等临床再出血情况或输血总量超过8单位时进行手术。
共纳入160例患者(单独使用肾上腺素组81例;肾上腺素加无水酒精组79例)。他们在年龄、性别、溃疡位置、入院时血红蛋白水平、休克情况和出血严重程度方面相匹配。初始止血效果相当:单独使用肾上腺素组81例中有79例(97.5%),肾上腺素加无水酒精组79例中有75例(94.9%)。两组在再出血(9例对6例)、急诊手术需求(12例对9例)、输血需求(中位数,3单位对2单位)、住院时间(中位数,5天对4天)、死亡率(4例对7例)以及4周时溃疡愈合情况(50例对46例)方面均未观察到差异。
内镜下注射肾上腺素后额外注射无水酒精并无优势。
