Short bowel syndrome (SBS) is a rare disease with potentially life-threatening consequences. In addition to intestinal failure-associated liver disease, infections and other complications related to central venous catheters (CVCs) cause a significant burden to patients with SBS and may even necessitate an intestinal transplant eventually. The need for long-term central venous access and the intestinal dysfunction associated with SBS drive the need for intestinal failure-specific approach to prevent and treat infections in patients with SBS. In bacterial infections, the line can often be salvaged with proficient antibiotic therapy. Repeated catheter replacements are predisposed to recurrent infections and thrombotic complications, which may limit the long-term survival of patients with SBS. Protocol-based CVC access procedures and daily care including taurolidine and ethanol catheter locks have been shown to reduce infection rates substantially. Compromised intestinal function in SBS predisposes to small bowel bacterial overgrowth, mucosal injury, and increased permeability. These pathophysiological changes are concentrated in a subset of patients with excessive bowel dilatation and frequent bowel-derived infections. In such patients, reconstructive intestinal surgery may be indicated. Probiotics have not been effective in infection prevention in SBS and carry a significant risk of complications. While more studies focusing on the prevention of infections and their complications are needed, protocol-based approach and multidisciplinary teams in the care of patients with SBS have been shown to reduce complications and improve outcomes.
短肠综合征(SBS)是一种罕见疾病,可能会导致危及生命的后果。除了与肠衰竭相关的肝病外,与中心静脉导管(CVC)相关的感染及其他并发症给SBS患者带来了沉重负担,甚至最终可能需要进行肠移植。对长期中心静脉通路的需求以及与SBS相关的肠道功能障碍,促使人们需要采取针对肠衰竭的方法来预防和治疗SBS患者的感染。在细菌感染中,通过熟练的抗生素治疗通常可以挽救导管。反复更换导管易引发反复感染和血栓形成并发症,这可能会限制SBS患者的长期生存。基于方案的CVC置管程序以及包括牛磺罗定和乙醇封管在内的日常护理已被证明可大幅降低感染率。SBS患者受损的肠道功能易导致小肠细菌过度生长、黏膜损伤和通透性增加。这些病理生理变化集中在一部分肠扩张过度且频繁发生肠道源性感染的患者中。对于此类患者,可能需要进行重建性肠道手术。益生菌在预防SBS感染方面无效,且存在显著的并发症风险。虽然需要更多关注预防感染及其并发症的研究,但已证明在SBS患者护理中采用基于方案的方法和多学科团队可减少并发症并改善预后。
