Gastrointestinal bleeding in infants and children is a potentially life-threatening problem that is encountered by virtually all practicing pediatric gastroenterologists. Youngsters with a normal hematocrit, hemodynamic stability, and a history consistent with an acute, self-limited illness most frequently need only close observation; others require more in-depth assessment and intervention. Meticulous attention to the patient's cardiopulmonary status and knowledge of appropriate pediatric resuscitation schemes form the cornerstones on which more specific therapeutic interventions are based. Many treatment techniques and approaches have been extrapolated for pediatric use from adult studies; the regimen implemented for a child should be individualized and based on factors such as patient size, underlying condition, and operator expertise. Although the physician treating pediatric gastrointestinal hemorrhage requires more than a modicum of patience and determination, this must be tempered with a ready willingness to seek consultation from surgical colleagues to ensure optimal outcomes. Knowledge of acid-suppressive and vasoactive medications is essential, as is familiarity with at least one injection technique and one thermocoagulation technique for hemostasis. Endoscopic sclerotherapy and variceal band ligation are equally efficacious in achieving control of acute variceal bleeding, but band ligation is emerging as the technique best suited for prophylaxis. Beta blockade appears to have a smaller and less well-defined role in pediatric variceal prophylaxis compared with that in adults, but random controlled trials are necessary to confirm this impression.
婴幼儿和儿童的胃肠道出血是一个潜在的危及生命的问题,几乎所有执业儿科胃肠病学家都会遇到。血细胞比容正常、血流动力学稳定且病史符合急性自限性疾病的患儿通常仅需密切观察;其他患儿则需要更深入的评估和干预。对患者心肺状况的细致关注以及对适当儿科复苏方案的了解是更具体治疗干预措施所基于的基石。许多治疗技术和方法是从成人研究中推断用于儿科的;为儿童实施的治疗方案应个体化,并基于患者体型、基础疾病和操作者专业技能等因素。虽然治疗小儿胃肠道出血的医生需要的不仅仅是一点点耐心和决心,但这必须与随时愿意向外科同事寻求会诊以确保最佳结果相平衡。了解抑酸和血管活性药物至关重要,熟悉至少一种止血注射技术和一种热凝技术也同样重要。内镜硬化治疗和曲张静脉套扎术在控制急性曲张静脉出血方面同样有效,但套扎术正成为最适合预防的技术。与成人相比,β受体阻滞剂在小儿曲张静脉预防中的作用似乎较小且定义不明确,但需要随机对照试验来证实这一印象。
