Background And Aim:
Colonoscopic perforation is a rare complication. We sought to determine its risk factors in patients with inflammatory bowel disease (IBD).
Materials And Methods:
The study group consisted of 19 IBD patients who had perforation secondary to diagnostic or therapeutic colonoscopy from January 2002 to October 2010. The control group consists of 76 IBD patients undergoing colonoscopy and no perforations that were matched based on indication in a 4:1 ratio to the study group. Demographic and clinical variables as well as perforation outcomes were analyzed by univariate and multivariate analyses.
Results:
There were a total of 5295 colonoscopies done during the study period in IBD patients of which 19 patients had perforation. The prevalence of perforation in IBD patients was 0.3%. Of the 19 patients, 12 had Crohn's disease (CD) and 7 had ulcerative colitis (UC). Patients in the perforation group were more likely treated with steroids (68.4% vs. 21.1%, p<0.001) and had severe disease on endoscopy (31.6% vs. 10.1%, p=0.03) than that in the control groups. On multivariate analysis, severe disease on endoscopy (adjusted odds ratio [aOR]=3.82, 95% confidence interval [CI]=1.03-15.24) and steroid treatment (aOR=7.68; 95% CI=1.48, 39.81) were independently associated with the risk of perforation. The median length of stay in the perforation group was 10 days (range 2-23 days). There was no mortality in our study.
Conclusions:
There appears to be a higher risk of colonoscopy-associated perforation in IBD patients with active disease and on steroids.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
