Background: Chronic intestinal failure (CIF) is a very rare Crohn’s disease (CD) complication.
Aim: To determine incidence of CIF treated with home parenteral nutrition (HPN) in adult CD patients and to isolate factors associated with severe CIF.
Methods:This retrospective multicentre study included 38 patients with CD-related CIF treated with HPN for at least 12 months in French HPN centres. Severe CIF was defined by a length of remnant small bowel of less than 100 cm or CIF occurrence within the 15 years following CD diagnosis.
Results: Median delay between CD diagnosis and CIF was 15 years. CIF incidence did not decrease over time (1.4/year before 1995 vs. 2.2/year after). Median number of small bowel resections per patient was three (range 1-8). Median small bowel resection, remnant and initial lengths were 160, 80 and 260 cm, respectively. Twenty-four per cent of patients developed stenosis within 1 year after CD diagnosis and 76% developed perforative complications within 2 years. In multivariate analysis, severe CIF, defined as CIF onset <15 years after CD diagnosis, was associated with a more recent CD diagnosis (odds ratio, 0.785; 95% confidence interval, 0.623-0.989). CIF occurred despite frequent use of immunosuppressants. Course of CD remained severe during HPN: immunosuppressants prescription occurred in 11 patients, surgery in six. Six patients died from CD (n = 2), HPN complications (n = 2) or other causes (n = 2).
Conclusions: Chronic intestinal failure requiring HPN is rare during CD. Incidence remained stable over time. Surgical procedures play a minor role in the occurrence of severe chronic intestinal failure compared to CD severity.
