The need for primary prophylaxis of variceal bleeding in children is unclear due to insufficient evidence of the efficacy of prophylactic therapy and the mortality and morbidity associated with the first bleeding event. Previous studies have provided estimates of mortality. We aimed to investigate the morbidity associated with acute variceal bleeding (AVB) in children and to identify contributing factors.
We retrospectively reviewed children with chronic liver disease or portal vein thrombosis admitted with acute upper gastrointestinal bleeding between 2000 and 2015.
Seventy AVB episodes in 57 children (median age 6 years, 52% girls) were included, 58% with cirrhosis and 30% portal vein thrombosis. Approximately 67% were the patient's first bleed. Post-AVB morbidity was present in 57% of all episodes and in 64% of first bleeds and included: ascites (34%), infection (30%), respiratory complications (24%), intensive care unit admission (20%), rebleed (11%), encephalopathy (7%), acute kidney injury (6%), and failure to control bleed (4%). Two patients died (4% of first bleeds, 8% of cirrhotics' first bleeds) within 6 weeks of bleeding. Median length of stay was 7 days. Overall morbidity was associated with total bilirubin (P = 0.001). Ascites after AVB was associated with pediatric end-stage liver disease (P = 0.0007), total bilirubin (P = 0.001), and cirrhosis (P = 0.006). Median length of stay was longer in patients with morbidities (18 vs 4 days, P < 0.0001).
Children with AVB suffer significant morbidity but have a low risk of death. Morbidity should therefore be considered in future studies measuring the risks and benefits of primary prophylaxis of first AVB in children.
由于预防性治疗的疗效和与首次出血事件相关的死亡率和发病率的证据不足,儿童门脉高压症出血的一级预防需求尚不清楚。先前的研究提供了死亡率的估计。我们旨在研究儿童急性静脉曲张出血(AVB)相关的发病率,并确定相关因素。
我们回顾性分析了 2000 年至 2015 年间因急性上消化道出血住院的患有慢性肝病或门静脉血栓形成的儿童患者。
共纳入 57 例儿童的 70 次 AVB 发作(中位年龄 6 岁,52%为女孩),58%为肝硬化,30%为门静脉血栓形成。约 67%为患者的首次出血。所有发作中有 57%存在出血后并发症,首次出血中有 64%存在出血后并发症,包括:腹水(34%)、感染(30%)、呼吸并发症(24%)、重症监护病房入住(20%)、再出血(11%)、脑病(7%)、急性肾损伤(6%)和出血无法控制(4%)。2 例患者(首次出血的 4%,肝硬化患者首次出血的 8%)在出血后 6 周内死亡。中位住院时间为 7 天。总体发病率与总胆红素相关(P=0.001)。AVB 后腹水与儿童终末期肝病(P=0.0007)、总胆红素(P=0.001)和肝硬化(P=0.006)相关。有并发症的患者中位住院时间较长(18 天 vs 4 天,P<0.0001)。
患有 AVB 的儿童会遭受严重的发病率,但死亡率低。因此,在未来研究测量儿童首次 AVB 一级预防的风险和获益时,应考虑发病率。
