Pediatric intestinal failure (IF) remains to be associated with significant morbidity and mortality, the most frequent underlying etiologies being short bowel syndrome (SBS), and primary motility disorders. Management aims to assure growth and development, while preventing complications and facilitating weaning off parenteral support (PS) by fully utilizing adaptation potential of the remaining gut. Probability of survival and weaning off PS is improved by coordinated multidisciplinary intestinal rehabilitation combining individualized physiological enteral and parenteral nutrition (PN), meticulous central line care and medical management with carefully planned surgical care. Increasing evidence suggests that autologous intestinal reconstruction (AIR) surgery is effective treatment for selected short bowel patients. Bowel lengthening procedures normalize pathological adaptation-associated short bowel dilatation with potential to support intestinal absorption and liver function by various mechanisms. Although reversed small intestinal segment, designed to prolong accelerated intestinal transit, improves absorption in adult SBS, its feasibility in children remains unclear. Controlled bowel obstruction to induce dilatation followed by bowel lengthening aims to gain extra length in patients with the shortest duodenojejunal remnant. Reduced PS requirement limits the extent of complications, improving prognosis and quality of life. The great majority of children with SBS can be weaned from PS while prognosis of intractable primary motility disorders remains poor without intestinal transplantation, which serves as a salvage therapy for life-threatening complications such as liver failure, central vein thrombosis or recurrent bloodstream infections.
小儿肠衰竭(IF)仍然与显著的发病率和死亡率相关,最常见的潜在病因是短肠综合征(SBS)和原发性动力障碍。治疗目标是确保生长发育,同时预防并发症,并通过充分利用剩余肠道的适应潜力促进脱离肠外支持(PS)。通过将个体化的生理性肠内和肠外营养(PN)、精心的中心静脉导管护理以及精心规划手术护理的医疗管理相结合的多学科协调肠道康复,可提高生存和脱离PS的概率。越来越多的证据表明,自体肠道重建(AIR)手术是治疗部分短肠患者的有效方法。肠延长手术可使与病理适应性相关的短肠扩张正常化,并有可能通过多种机制支持肠道吸收和肝功能。尽管旨在延长加速肠道转运的倒置小肠段可改善成人SBS患者的吸收,但在儿童中的可行性仍不明确。通过控制肠梗阻以诱导扩张,随后进行肠延长,旨在使十二指肠空肠残端最短的患者获得额外长度。减少对PS的需求可限制并发症的程度,改善预后和生活质量。绝大多数SBS患儿可以脱离PS,而对于顽固性原发性动力障碍,在没有肠道移植的情况下预后仍然很差,肠道移植是治疗诸如肝衰竭、中心静脉血栓形成或反复血流感染等危及生命并发症的挽救性治疗方法。
