Discrepancies in surgical rates for CD are observed between population-based studies and referral cohorts. As medical therapy advances further, temporal trends in rates of surgical ostomy creation need to be re-evaluated.
Ma et al. conducted a population-based surveillance using the Discharge Abstract Database of the Calgary Health Zone . Data for the period between April 1, 2002 and March 31, 2009 were included. Patients aged ≥18 years were identified who were admitted for CD and underwent surgical stoma creation (n=427).
The overall stoma creation rate was 1.9 stomas per 100 person-years (95% CI: 1.5-2.5). The rate of stoma creation between 2002 and 2009 trended downwards by an average of 5.8% per year (95% CI: −11.4%, 0.2%). It decreased from 2.3 stomas per 100 person-years (95% CI: 1.8-3.0) in 2002 to 1.6 stomas per 100 person-years (95% CI: 1.3-2.1) in 2009. When stratified by surgical indication, the rate of emergency-ostomy creation dec...
