The incidence and prevalence of obesity have been rising in the United States, negatively impacting the population's overall health. This study seeks to better understand the impact of obesity on patients presenting with acute alcoholic pancreatitis (AAP). Data collected using the National Inpatient Sample (NIS) from the fourth quarter of 2015 to 2019 with a principal diagnosis of AAP and secondary obesity were analyzed. Confounders were adjusted for multivariate regression analysis using a multitude of factors. A total of 229,510 patients were identified with a diagnosis of AAP, among which 14,150 were also identified as obese. A majority of the sample, both obese and non-obese patients with AAP, were middle-aged white females. The average comorbidity index (CCI) was lower in the non-obese cohort compared to the obese cohort. Compared to non-obese patients, patients with AAP who were obese had higher hospital charges and a longer LOS (p<0.05. Additionally, compared to non-obese patients, obese patients with AAP had higher odds of mortality and adverse events, such as acute renal failure and respiratory failure (p<0.05). Current research supports these complications, which have shown an association with increased visceral fat in or around the pancreas that can ultimately worsen acute pancreatitis outcomes and aggravate AAP by damaging the intestinal mucosal barrier. These findings should be considered when treating obese patients who develop AAP. Strategies to increase surveillance of such patients should be implemented to reduce complications and mortality in this population.
