Acute gastrointestinal haemorrhage is a common medical emergency that has a hospital mortality of approximately 10%. Peptic ulcer bleeding, complicating non-steroidal anti-inflammatory drugs, aspirin or Helicobacter pylori infection is the most common cause of major bleeding. Gastro-oesophageal varices are less common but managing the underlying liver disease and the severity of bleeding may be demanding. The prognosis of patients presenting with acute bleeding is dictated by the presence of medical co-morbidities and by the severity of liver disease in patients with varices. Validated prognostic scoring systems, based upon the severity of bleeding, diagnosis, endoscopic findings and extent of co-morbidities, predict mortality and have clinical utility. The treatment of non-variceal bleeding is based upon cardiovascular resuscitation followed by endoscopic therapy in patients with active bleeding or major stigmata of recent haemorrhage. Proton pump inhibitor drugs reduce the risk of re-bleeding but have little effect on mortality. Emergency surgery is undertaken for uncontrolled bleeding or re-bleeding that cannot be controlled by further endoscopic therapy. Oesophageal varices are managed by fluid resuscitation, antibiotics and endoscopic band ligation. Vasoactive drugs may stop active bleeding but have no effect upon mortality. Management of the complications of the underlying liver disease and complete variceal ablation in a banding programme are essential. Gastric varices are treated by injection with tissue adhesives or transjugular intrahepatic porto-systemic shunt (TIPSS) insertion. Surgical intervention has little role in the management of varices and patients who do not respond to endoscopic therapies are best treated by TIPSS.
急性胃肠道出血是一种常见的医疗急症,医院死亡率约为10%。消化性溃疡出血,并发非甾体抗炎药、阿司匹林或幽门螺杆菌感染,是大出血的最常见原因。胃食管静脉曲张较少见,但处理潜在的肝脏疾病和出血的严重程度可能具有挑战性。急性出血患者的预后取决于合并症的存在以及静脉曲张患者肝脏疾病的严重程度。基于出血严重程度、诊断、内镜检查结果和合并症范围的经过验证的预后评分系统可预测死亡率并具有临床实用性。非静脉曲张出血的治疗基于心血管复苏,随后对有活动性出血或近期出血主要征象的患者进行内镜治疗。质子泵抑制剂药物可降低再出血风险,但对死亡率影响不大。对于无法控制的出血或无法通过进一步内镜治疗控制的再出血,需进行急诊手术。食管静脉曲张的处理包括液体复苏、抗生素和内镜下套扎术。血管活性药物可能会止住活动性出血,但对死亡率没有影响。处理潜在肝脏疾病的并发症以及在套扎方案中完全消除静脉曲张至关重要。胃静脉曲张通过注射组织粘合剂或经颈静脉肝内门体分流术(TIPSS)进行治疗。手术干预在静脉曲张的管理中作用不大,对内镜治疗无反应的患者最好采用TIPSS治疗。
