OBJECTIVE: To determine the incidence and maternal-fetal outcome of fi
rst-trimester pancreatitis at one institution. STUDY DESIGN: A retrosp
ective study of pancreatitis presenting during the first trimester of
pregnancy over a 10-year period at Magee Womens Hospital. RESULTS: The
re were 11 cases, for an incidence of 0.1/1,000 live births. There was
no maternal mortality. Three patients elected voluntary termination,
and eight pregnancies proceeded to term. All delivered at greater than
or equal to 35 weeks. The mean gestational age was 38.9+/-2.1 weeks (
mean+/-SD), and mean birth weight was 3,103+/-641 g. There were no adv
erse neonatal outcomes, although one patients had a fetus with severe
intrauterine growth retardation. Maternal morbidity and complications
were due mainly to gallstone pancreatitis, which was the most commonly
identified cause of pancreatitis, and three patients underwent cholec
ystectomy during pregnancy (mean number of admissions, 2.27+/-2.1). CO
NCLUSION: Patients should be advised of the relapsing nature of pancre
atitis that presents during the first trimester. However, there is a g
ood prognosis for pregnancy outcome.
