AimPrevious reports describing Clostridium difficile colitis (CDC) developing after the closure of a loop ileostomy suggest it is severe. In this study the incidence of CDC following ileostomy closure and its effect on the postoperative outcome have been studied.MethodPatients undergoing closure of loop ileostomy from 2004 to 2008 were analysed using the Nationwide Inpatient Sample. Patients who developed postoperative CDC (n = 217) were matched 10:1 to a propensity-score-matched cohort of patients without CDC (n = 13 245). Linear and logistic regression were used to examine the effect of CDC on hospital cost (US dollars), length of stay and mortality rates. Population resampling was performed using nearest neighbour bootstrapping to confirm the validity of the results.ResultsThe incidence of CDC following ileostomy closure was 16 per 1000 patients. The mean length of stay was 11.5 days longer among CDC patients (P < 0.0001), with a greater cost of hospitalization of US$21 240 (P < 0.0001). There was no difference in mortality between the cohorts.ConclusionCDC following ileostomy closure is an uncommon, costly and morbid complication. Patients undergoing stoma closure are at high risk for an adverse outcome if they have CDC. Should it develop they should be aggressively treated.Colorectal Disease © 2013 The Association of Coloproctology of Great Britain and Ireland.
