Endoscopic therapy reduces the recurrence of bleeding from actively bleeding peptic ulcers and those with visible vessels. However, the use of endoscopic therapy for ulcers with adherent clots remains controversial. The purpose of this study was to determine whether removal of clot from an ulcer and endoscopic therapy reduces the frequency of recurrent bleeding.
Patients with acute upper GI bleeding from peptic ulcers with adherent clots and no active bleeding were enrolled in a multicenter study. At each center patients were stratified for age, use of nonsteroidal anti-inflammatory drugs, and ulcer location, and were randomized to endoscopic or medical management. Endoscopic therapy consisted of injection of the base of the adherent clot with a solution of epinephrine and mechanical removal of the clot. The base of the ulcer and any stigmata of bleeding were then coagulated until cavitation and adequate coagulation were obtained. Patients in both groups received standard medical therapy for peptic ulcer. Patients were evaluated for recurrence of bleeding for 1 month.
Fifty-six patients were enrolled. Rates of recurrent bleeding were 34.3% (12/35) in the medical treatment arm versus 4.8% (1/21) in the endoscopic treatment arm (p < 0.02).
In patients with GI bleeding caused by gastric or duodenal ulcers with an adherent clot found on endoscopy, endoscopic therapy with injection of the base of the clot, clot removal, and heat probe coagulation significantly reduces the rate of recurrent bleeding compared with medical therapy alone.
内镜治疗可降低活动性出血性消化性溃疡及有可见血管的溃疡的出血复发率。然而,对于有附着血凝块的溃疡使用内镜治疗仍存在争议。本研究的目的是确定从溃疡中清除血凝块并进行内镜治疗是否能降低出血复发频率。
患有急性上消化道出血且有附着血凝块且无活动性出血的消化性溃疡患者被纳入一项多中心研究。在每个中心,患者按年龄、非甾体抗炎药的使用情况和溃疡位置进行分层,并随机分为内镜治疗组或药物治疗组。内镜治疗包括用肾上腺素溶液注射附着血凝块的底部并机械清除血凝块。然后对溃疡底部和任何出血征象进行凝固,直至形成空洞并获得充分凝固。两组患者均接受消化性溃疡的标准药物治疗。对患者进行1个月的出血复发评估。
共纳入56例患者。药物治疗组的出血复发率为34.3%(12/35),而内镜治疗组为4.8%(1/21)(p<0.02)。
在内镜检查发现有附着血凝块的胃或十二指肠溃疡引起的胃肠道出血患者中,与单纯药物治疗相比,内镜下注射血凝块底部、清除血凝块和热探头凝固治疗可显著降低出血复发率。
