Repeat intestinal resections in CD

Issue 07

Clinical Question

How many patients with Crohn’s disease (CD) who have an intestinal resection require a second resection within 10 years?

Editor’s Bottom Line

The rate of a second intestinal resection in CD patients is approximately 35%. This rate has been decreasing since the 1980’s.

Editorial Note

Data from the University of Alberta (Ma et al, submitted CGH) identifies that anti-TNF therapy within 2 years of CD diagnosis markedly reduces intestinal resection rates; implying early control of inflammation improves patient outcomes.

Synopsis

A systematic literature search in three databases retrieved a total of 12 population-based studies investigating the incidence of second intestinal resections for the treatment of CD. The timespan of the studies ranged from 1955 through to 2009; two studies reported incidence for pediatric CD.

The overall risk for a second intestinal resection in patients with CD was 28.7% based upon 8 studies. Pooling results from 6 studies, the 5-year risk for second resection was 24.2% and the 10-year risk for a second resection was 35.0%. Pre-1980 studies reported that ~50% of patients with CD had a second intestinal resection within 10 years. Studies conducted after 1980 reported that less than one third of patients required a second resection within 10 years.
