- Background: Regional studies on inflammatory bowel disease (IBD) suggest an increasing prevalence over time, but no nationwide estimate has been published so far.Aim: To estimate the IBD prevalence in 2010 in Sweden overall, by disease, and in specific patient segments.Methods: Patients were identified according to international classification codes for ulcerative colitis and Crohn's disease in in-patient care (1987-2010), day surgery and nonprimary out-patient care (1997-2010) in the nationwide Swedish Patient Register.Results: Requiring two or more diagnoses of IBD in nonprimary care, a total of 61344 individuals with physician-diagnosed IBD were alive in Sweden in 2010 (mean age 50years; 51% men), corresponding to a prevalence of 0.65% (95% CI, 0.65-0.66). The prevalence increased with age, and peaked in women at ages 50-59years and in men at ages 60-69years. Adding the requirement of IBD as main (vs. main or contributory) diagnosis code, or diagnosis from an internal medicine/gastroenterology/surgery department did not change the prevalence estimate. Prevalence of actively treated disease (defined as two or more IBD-related visits, of which one occurred in 2010, plus at least one dispensed prescription of IBD-related drugs in 2010) was 0.27% (95% CI, 0.27-0.28).Conclusions: The Swedish nationwide register-based IBD prevalence was higher compared with previous Swedish and international estimates. While prevalence estimates were robust across different case definitions, once two or more visits were required, only about one-third of prevalent patients were drawing resources from specialised care in 2010.

- In order to assess the risk of long-term complications following endoscopic sphincterotomy (ES) for common bile duct stones (CBDS), we conducted a cohort study. The study included 1,113 patients who underwent ES for CBDS in six different hospitals in central Sweden between 1977 and 1990. Through the use of the Swedish population registry, each patient was assigned five population-based controls matched for sex and age. Linkage to the Inpatient Registry yielded information on morbidity and mortality for the patients as well as for the controls. After one year of washout, there were 964 patients available for follow-up. The mean age was 70.6 years, 57% were women, and the mean length of follow-up was 8.9 years. The patients’ overall morbidity was significantly higher and we observed a tendency towards increased mortality as well. Recurrent CBDS was diagnosed in 4.1% of the patients. Acute cholangitis with a hazard ratio (HR) of 36 (95%CI 11–119.4) was associated with recurrent CBDS in 39% of the patients. HR for acute pancreatitis was 6.2 (95%CI 3.4–11.3) and only one patient had CBDS at the same time. In conclusion, we consider acute pancreatitis and cholangitis both as probable long-term complications after ES.
