Objective:
To determine the risk of diverticular perforation associated with current and ever use of corticosteroids, opiate analgesics, non-steroidal anti-inflammatory drugs, aspirin, cyclo-oxygenase-2 inhibitors, statins and calcium antagonists.
Design, Setting And Participants:
Case-control analysis using conditional logistic regression analysis of data from the UK General Practice Research Database. The study involved 899 cases of incident diverticular perforation and 8980 population controls from 1990 to 2005.
Main Outcome Measures:
Odds ratios (ORs) are presented for perforation associated with use of corticosteroids, opiate analgesics, non-steroidal anti-inflammatory drugs, aspirin, cyclo-oxygenase-2 inhibitors, statins and calcium antagonists. Data were adjusted for smoking, comorbidity, prior abdominal pain and body mass index.
Results:
A total of 899 patients with an incident diagnosis of perforated diverticular disease were identified. Current use of opiate analgesics (OR=2.16; 95% CI 1.55 to 3.01) and oral corticosteroids (OR=2.74; 95% CI 1.63 to 4.61) was associated with a two- and threefold increase in the risk of diverticular perforation, respectively. Current use of a calcium antagonist and aspirin were not associated with an increased risk of diverticular perforation. Current statin use was associated with a reduction in the risk of perforation (OR=0.44; 95% CI 0.20 to 0.95).
Conclusion:
Perforated diverticular disease is a serious surgical emergency with current opiate analgesics and oral corticosteroids being strongly associated with an increased risk of diverticular perforation.

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...

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...
