Abstract

Objective: To determine relationships among pregnancy (during and postpartum), acute pancreatitis, and gallstones.

Patients and methods: In this retrospective population-based case-control study, we identified all 12- to 50-year-old Rochester, Minn, females diagnosed between 1976 and 1991 as having acute pancreatitis (cases). For each case, we matched 4 women of the same age (+/- 6 years) with no history of acute pancreatitis (controls). Acute pancreatitis was defined as associated with pregnancy if it occurred from 10 months prior to delivery to delivery and with the postpartum period if it occurred within 10 months of the date of delivery. Logistic regression was used to assess associations between pregnancy-related acute pancreatitis, age, gallstone occurrence, and alcohol use.

Results: In a cohort of 61 women who developed acute pancreatitis and 244 controls, the relative risk for acute pancreatitis associated with pregnancy was 1.43 (95% confidence interval, 0.61-3.40). All 10 cases of acute pancreatitis associated with pregnancy occurred in the postpartum period. Gallstones were present in 6 of them compared with 13 of 51 women with non-pregnancy-related acute pancreatitis (P < .05). Women with postpartum-related pancreatitis were younger than those with non-pregnancy-related pancreatitis (mean, 28 vs 36 years; P < .05). Alcohol was not associated with pregnancy-related pancreatitis.

Conclusions: Acute pancreatitis during the postpartum period is not directly related to pregnancy but is associated with gallstones and occurs in younger women.
