The benefit of nonsurgical therapy in the treatment of active nonvariceal upper gastrointestinal tract hemorrhage is uncertain. I performed a prospective controlled trial of endoscopic multipolar electrocoagulation for active upper gastrointestinal hemorrhage. Patients were considered for entry if they had a bloody nasogastric aspirate, melena, or hematochezia, and any of the following: unstable vital signs, a requirement of greater than or equal to 2 units of blood per 12 hours, or a drop in hematocrit of greater than or equal to 6 percent in 12 hours. Forty-four patients were randomly assigned to receive multipolar electrocoagulation or sham multipolar electrocoagulation if endoscopy revealed active bleeding from an ulcer (24 patients), a Mallory-Weiss tear (17), or a vascular malformation (3). The group receiving multipolar electrocoagulation did significantly better in terms of hemostasis (90 percent vs. 13 percent, P less than 0.0001), mean (+/- SE) transfusion requirements (2.4 +/- 0.9 vs. 5.4 +/- 0.9 U; P = 0.002), mean number of hospital days (4.4 +/- 0.8 vs. 7.2 +/- 1.1, P = 0.02), and percentage needing emergency surgery or another intervention (14 vs. 57 percent, P = 0.01). Although mortality was lower in the group receiving multipolar electrocoagulation (0 vs. 13 percent), this difference was not statistically significant. The mean cost of hospitalization for treated patients was less than half that for the controls ($ 3,420 +/- 750 vs. $ 7,550 +/- 1,480, P = 0.001). I conclude that multipolar electrocoagulation markedly improves the hospital course in patients with major, nonvariceal upper gastrointestinal hemorrhage.
非手术疗法治疗活动性非静脉曲张性上消化道出血的益处尚不确定。我对内镜多极电凝术治疗活动性上消化道出血进行了一项前瞻性对照试验。如果患者有血性鼻胃管抽吸物、黑便或便血,且符合以下任何一项,则考虑纳入研究:生命体征不稳定、每12小时需要输注大于或等于2单位血液、或12小时内血细胞比容下降大于或等于6%。如果内镜检查发现溃疡(24例患者)、马洛里-魏斯撕裂(17例)或血管畸形(3例)引起的活动性出血,44例患者被随机分配接受多极电凝术或假多极电凝术。接受多极电凝术的组在止血方面明显更好(90%对13%,P<0.0001),平均(±标准误)输血需求量(2.4±±0.9对5.4±±0.9单位;P = 0.002),平均住院天数(4.4±±0.8对7.2±±1.1,P = 0.02),以及需要急诊手术或其他干预的百分比(14%对57%,P = = 0.01)。虽然接受多极电凝术的组死亡率较低(0对13%),但这种差异无统计学意义。治疗患者的平均住院费用不到对照组一半(3420±±750美元对7550±±1480美元,P = = 0.001)。我得出结论,多极电凝术显著改善重度非静脉曲张性上消化道出血患者的住院病程。
