After endoscopic treatment to control bleeding of peptic ulcers, bleeding recurs in 15 to 20 percent of patients. In a prospective, randomized study, we compared endoscopic retreatment with surgery after initial endoscopy. Over a 40-month period, 1169 of 3473 adults who were admitted to our hospital with bleeding peptic ulcers underwent endoscopy to reestablish hemostasis. Of 100 patients with recurrent bleeding, 7 patients with cancer and 1 patient with cardiac arrest were excluded from the study; 48 patients were randomly assigned to undergo immediate endoscopic retreatment and 44 were assigned to undergo surgery. The type of operation used was left to the surgeon. Bleeding was considered to have recurred in the event of any one of the following: vomiting of fresh blood, hypotension and melena, or a requirement for more than four units of blood in the 72-hour period after endoscopic treatment.
Of the 48 patients who were assigned to endoscopic retreatment, 35 had long-term control of bleeding. Thirteen underwent salvage surgery, 11 because retreatment failed and 2 because of perforations resulting from thermocoagulation. Five patients in the endoscopy group died within 30 days, as compared with eight patients in the surgery group (P=0.37). Seven patients in the endoscopy group (including 6 who underwent salvage surgery) had complications, as compared with 16 in the surgery group (P=0.03). The duration of hospitalization, the need for hospitalization in the intensive care unit and the resultant duration of that stay, and the number of blood transfusions were similar in the two groups. In multivariate analysis, hypotension at randomization (P=0.01) and an ulcer size of at least 2 cm (P=0.03) were independent factors predictive of the failure of endoscopic retreatment.
In patients with peptic ulcers and recurrent bleeding after initial endoscopic control of bleeding, endoscopic retreatment reduces the need for surgery without increasing the risk of death and is associated with fewer complications than is surgery.
在内镜治疗消化性溃疡出血后,15%至20%的患者会再次出血。在一项前瞻性随机研究中,我们比较了初次内镜检查后内镜再治疗与手术治疗的效果。在40个月的时间里,我院收治的3473例因消化性溃疡出血入院的成年患者中,1169例接受了内镜检查以重新建立止血。在100例复发性出血患者中,7例患有癌症和1例心脏骤停患者被排除在研究之外;48例患者被随机分配接受立即内镜再治疗,44例被分配接受手术治疗。手术类型由外科医生决定。在内镜治疗后72小时内,若出现以下任何一种情况,则认为出血复发:呕出鲜血、低血压和黑便,或需要输注超过4单位血液。
在分配接受内镜再治疗的48例患者中,35例出血得到长期控制。13例接受了挽救性手术,11例是因为再治疗失败,2例是因为热凝导致穿孔。内镜检查组有5例患者在30天内死亡,而手术组有8例患者死亡(P = 0.37)。内镜检查组有7例患者(包括6例接受挽救性手术的患者)出现并发症,而手术组有16例患者出现并发症(P = 0.03)。两组的住院时间、入住重症监护病房的需求及住院时间、输血量相似。多因素分析显示,随机分组时的低血压(P = 0.01)和溃疡大小至少2 cm(P = 0.03)是内镜再治疗失败的独立预测因素。
对于消化性溃疡出血初次内镜控制后复发性出血的患者,内镜再治疗可减少手术需求,且不增加死亡风险,与手术相比并发症更少。
