Introduction: An estimated 12% of women will develop cholelithiasis during pregnancy. Nearly 70% of cases of acute pancreatitis in pregnancy are attributable to gallstone disease. Acute biliary pancreatitis (ABP) during pregnancy can cause serious morbidity, but there is a paucity of literature on how outcomes and management of ABP in pregnancy have changed with time. Hence, we sought to study trends of ABP and its management in pregnant women over the last two decades at a national level.

Methods: We used the National (Nationwide) Inpatient Sample to identify all women (≥18 years) with an inpatient admission for ABP in the United States from 2002 to 2018. We excluded data from 2015-2016 due to less than expected incidence attributable to a transition from the ICD-9 to ICD-10 coding system. Baseline patient characteristics were compared between pregnant and non-pregnant women with ABP utilizing Chi-square and two sample t-tests. Trends in outcomes and management were analyzed using Cochran-Armitage and F-Tests.

Results: Among 40,359 pregnant patients and 476,965 non-pregnant women hospitalized for ABP, a higher proportion of pregnant women with ABP were Hispanic (p< 0.001) and used Medicaid (p< 0.001) than non-pregnant women on univariate analysis (Table 1). Trend analyses from 2002-2018 revealed an increasing proportion (p< 0.001) of ABP admissions in pregnant females (Figure 1). An increasing trend was observed for ERCP (p< 0.001) and cholecystectomy (p< 0.001) in pregnant women admitted for ABP (Figure 1). Severe acute pancreatitis increased in both pregnant and non-pregnant patients across time, but a lower increase was seen in the pregnant cohort. Overall mortality in the pregnant cohort remained low (< 0.1%), ICU admission was less than 0.6%, and mean length of stay decreased from 5 days to 4 days (p< 0.001) for pregnant women with ABP.

Discussion: Over the last two decades, an increasing proportion of pregnant women are admitted with ABP, and therapeutic interventions (ERCP and cholecystectomy) are occurring more frequently with favorable hospital outcomes. These national-level data strongly support current surgical and endoscopic management guidelines of ABP in pregnancy.
