Background & Aims:
Pyogenic liver abscess (PLA) is a rare and severe extraintestinal complication in patients with inflammatory bowel disease (IBD). However, the incidence of PLA in patients with IBD remains unknown.
Methods:
A nationwide cohort study was conducted by analysing data from the National Health Insurance Research Database in Taiwan. Patients with IBD (N = 11 504) from 2000 to 2010 and control participants without IBD (N = 46 016) were included in this study. We analysed the risks of PLA by using competing-risks (death) regression models.
Results:
The incidence of PLA was higher in the IBD cohort than in the control cohort (6.72 vs 4.06 per 10 000 person-years), with an adjusted subhazard ratio (SHR) of 1.46 (95% confidence interval [CI], 1.01-2.12). Patients with IBD who required two or more hospitalizations per year and underwent laparotomy had an increased risk of PLA. Patients with ulcerative colitis were more likely to develop PLA than were those with Crohn's disease (incidence, 8.56 vs 5.45 per 10 000 person-years; adjusted SHR, 1.65 vs 1.32). Among the IBD cohort, age and gender did not affect PLA risk. Patients with diabetes mellitus or percutaneous aspiration of the gallbladder and biliary tract and who underwent endoscopic insertion of a biliary drainage tube exhibited a significantly increased risk of PLA.
Conclusions:
Patients with IBD exhibited an increased risk of developing PLA, particularly those with ulcerative colitis. Knowledge of the expected frequency and potential risk for this severe extraintestinal infection may minimize the serious consequences.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
