Fat malabsorption is central to the pathophysiology of short bowel syndrome (SBS). It occurs in patients with insufficient intestinal surface area and/or function to maintain metabolic and growth demands. Rapid intestinal transit and impaired bile acid recycling further contribute to fat malabsorption. A significant portion of patients require parenteral nutrition (PN) for their survival but may develop sepsis and liver dysfunction as a result. Despite advancements in the treatment of SBS, fat malabsorption remains a chronic issue for this vulnerable patient population. Peer-reviewed literature was assessed on the topic of fat malabsorption in SBS. Current management of patients with SBS involves dietary considerations, PN management, antidiarrheals, glucagon-like peptide 2 agonists, and multidisciplinary teams. Clinical trials have focused on improving intestinal fat absorption by facilitating fat digestion with pancreatic enzymes. Targeting fat malabsorption in SBS is a potential pathway to improving lifestyle and reducing morbidity and mortality in this rare disease.
脂肪吸收不良是短肠综合征(SBS)病理生理学的核心。它发生在肠道表面积和/或功能不足以维持代谢和生长需求的患者中。快速的肠道转运和胆汁酸循环受损进一步导致脂肪吸收不良。很大一部分患者需要肠外营养(PN)才能生存,但可能因此发生脓毒症和肝功能障碍。尽管 SBS 的治疗取得了进展,但脂肪吸收不良仍然是这一脆弱患者群体的慢性问题。对 SBS 中脂肪吸收不良这一主题的同行评议文献进行了评估。目前 SBS 患者的管理包括饮食考虑、PN 管理、止泻药、胰高血糖素样肽 2 激动剂和多学科团队。临床试验侧重于通过使用胰腺酶促进脂肪消化来改善肠道脂肪吸收。针对 SBS 中的脂肪吸收不良是改善生活方式和降低这种罕见疾病发病率和死亡率的潜在途径。
