摘要:

目的 分析十二指肠来源上消化道出血病例的内镜下止血效果及其相关因素。方法 回顾2011年1月至2018年12月于北京协和医院消化内镜中心、因上消化道出血行急诊胃镜且内镜下判断出血来源于十二指肠的病例,统计病例的基本信息、病灶相关信息、内镜下止血方法等,分析内镜止血效果及其相关因素。结果 共纳入128例患者,其中男性106例(82.8%),中位年龄55(39,67)岁。出血原因包括消化性溃疡(79.7%)、占位病变(14.1%)、血管畸形(3.9%)和憩室(2.3%),共53例(41.4%)患者接受内镜下止血,6例(4.7%)接受介入栓塞或手术治疗。接受内镜下止血的病例中,35例(66.0%)为钛夹机械止血,15例(28.3%)为钛夹联合其他方式止血,3例(5.7%)为药物局部注射。内镜止血的技术成功率为94.3%,但10例(18.9%)病变发生再出血。病灶位于球部后壁是内镜止血失败的危险因素(OR=31.333,95% CI=2.172~452.072,P=0.021);而溃疡≥1 cm是病变再出血的危险因素(OR=7.000,95% CI=1.381~35.478,P=0.023)。结论 十二指肠出血病因仍以消化性溃疡为主,亦存在如憩室出血等特殊原因。病灶位于球部后壁是内镜止血失败的危险因素;较大的溃疡是止血后再出血的危险因素。Forrest分级与短期再出血无相关性。

Abstract:

Objective To analyze clinical characteristics and short-term efficacy of endoscopic hemostasis in acute duodenal hemorrhage. Methods A retrospective study was conducted for the patients who received endoscopy in the PUMC Hospital due to upper gastrointestinal bleeding and were confirmed to be on account of duodenal lesions for bleeding from January 2011 to December 2018.Clinical information of patients was collected,including demographics,comorbidities,and medication use.Endoscopic information included the origin of bleeding,the number and location of lesions,Forrest classes and size of ulcers,and endoscopic therapeutic methods.Factors that could be relative to the failure of endoscopic hemostasis or short-term recurrence of hemorrhage in these patients were analyzed. Results Among all the patients with duodenal hemorrhage,79.7%(102/128)were due to ulcers,14.1%(18/128)to tumors,3.9%(5/128)to vascular malformation,and 2.3%(3/128)to diverticulum.Fifty-three(41.4%)patients received endoscopic hemostasis,and six patients(4.7%)received surgery or interventional embolization after the endoscopic test.Among the patients receiving endoscopic hemostasis,5.7%(3/53),66.0%(35/53),and 28.3%(15/53)received injection therapy,mechanical therapy,and dual endoscopic therapy,respectively,and 94.3% of them were cured.However,10(18.9%)of them experienced recurrence of hemorrhage and 3 patients died during hospitalization.Only one patient suffered from perforation after the second endoscopic treatment.Lesions located on the posterior wall of bulb appeared to be a risk factor for the failure of endoscopic hemostasis(OR=31.333,95% CI=2.172-452.072,P=0.021).The lesion diameter≥1 cm was a risk factor of rebleeding after endoscopic therapy(OR=7.000,95% CI=1.381-35.478,P=0.023).Conclusions Peptic ulcers were always blamed and diverticulum could also be a common reason for duodenal hemorrhage,which was different from the etiological constitution of acute upper gastrointestinal hemorrhage.Lesions locating on the posterior wall of the duodenum had a higher potential to fail the endoscopic hemostasis.The lesion diameter≥1 cm was a predictive factor for short-term recurrence.Forrest classes of ulcers at duodenum did not significantly affect the endoscopic therapeutic efficacy or prognosis.
