Outcomes Of Children With Short Bowel Syndrome: Experiences In A Multidisciplinary Intestinal Rehabilitation Unit Over Two Decades

Abstract

Short bowel syndrome (SBS) is a rare but serious form of organ failure, and patients with SBS depend on total parenteral nutrition (PN) to maintain growth and development. The present study aimed to evaluate the experiences and outcomes of children with SBS managed by a multidisciplinary intestinal rehabilitation programme in a tertiary paediatric centre. A retrospective single-centre analysis of all paediatric patients with a clinical diagnosis of SBS between 2001 and 2022 was performed. Clinical outcomes and their predictors were extracted and analysed. Of the 64 children included in the study, 43 (67%) had extensive necrotising enterocolitis. The median bowel length was 45 cm (interquartile range (IQR) = 18–65) and 18.9% (IQR = 10–28.5) of the expected length based on age. Over a mean follow-up period of 8.9 years, 57 patients (89%) survived, and 50 (78%) weaned off PN. The presence of intestinal failure-associated liver disease (IFALD) (OR = 6.375, = 0.02) and patients managed before the introduction of fish oil-based PN in 2007 (OR = 5.895, = 0.001) were significant predictors of mortality. There was an overall improvement in survival over time ( = 0.003). Ultrashort bowel length was not associated with significantly higher mortality (OR = 1.1, = 0.65) but was a poor prognostic factor for weaning off PN (OR = 3.57, p = 0.004). Among all patients who weaned off PN, two had bowel lengthening procedures and one received a glucagon-like peptide 2 (GLP-2) analogue. A multidisciplinary intestinal rehabilitation programme offers a comprehensive approach for patients with SBS and has been shown to be effective with favourable outcomes. Improvements in the choice of PN and the development of new treatment strategies potentially improved the survival and enteral autonomy of SBS patients. III
