Among patients with Crohn's disease (CD) who receive long-term treatment, intestinal failure (IF) is one of the most serious complications. However, there have been few reports concerning the occurrence rate and characteristics of IF in CD patients. The aim of this study was to clarify the risk and characteristics of IF in patients with CD.
The present study was a retrospective study in 12 hospitals. CD patients who underwent initial surgery at any of the 12 hospitals between 1970 and 2009 were collected (n = 1703). Those who developed IF were reviewed (n = 68), and the cumulative risk of IF was analyzed by Kaplan–Meier method. In addition, IF patients who underwent initial surgery at other hospitals and were then treated at any of the 12 hospitals were also reviewed (n = 33). Thus, a total of 101 IF patients was collected, and the cumulative risk of IF-related death was analyzed.
Definition of IF: CD patients who required intravenous infusion therapy at least twice per week for a period of more than 1 year because of inability to maintain protein-energy, fluid, electrolyte, or micronutrient balance, which resulted from surgical resection were defined as having IF in the present study.. Patients who received intravenous infusion therapy for bowel inflammation, bowel stenosis, fistula, abscess, and/or anal disease were excluded.
The cumulative risk of IF after the initial surgery was 0.8% (5 years), 3.6% (10 years), 6.1% (15 years), and 8.5% (20 years). In CD patients with IF, mean ages at initial surgery, IF occurrence, and at the time of the study were 28.2, 38.2, and 46.1 years, respectively. The mean number of surgeries per patient was 3.3. The mean length of the remnant small bowel was 163cm. Twelve IF patients (12%) had died and the cumulative risk of IF-related death by the time from the occurrence of IF was 1.1% (3 years), 3.7% (5 years), 6.5% (7 years), and 8.9% (10 years). Central venous catheter-related bloodstream infection (CRBSI) and liver dysfunction were the most frequent complications, and the poor prognosis was mainly due to these complications.
The occurrence of IF and IF-related death in CD patients is not rare over the long-term. There is a pressing need to develop strategies for the prevention and management of IF.
