Outcome of the biliary acute pancreatitis is not associated with body mass index

There are few studies published that considered overweight and obesity as potential risk factors for the development of complications in AP. Conclusions regarding the type of complications according to the Atlanta criteria as well as the mortality rate are not unique among different authors.5Y7 There is only 1 meta-analysis that revealed obesity as a prognostic factor in AP, favoring the development of systemic and local complications, but having no impact on mortality rate.8 Contrary to the results of De Waele et al,1 our study did not show any impact of BMI on the severity and the outcome of patients with acute biliary pancreatitis. Because we analyzed an even bigger group of obese patients (99 patients with BMI 9 30), we think that impact of BMI should be reconsidered in further studies
