A cute pancreatitis in pregnancy is a relatively common problem. The incidence is almost 1/1000-10.000 pregnancies. [1, 2] It can be caused by gallstones, idiopathic hyperlipidemia, alcohol abuse, and, less commonly by, hyperparathyroidism, trauma, and medications. [1-3] Gallbladder stones are the most frequently reported etiology and are often diagnosed in the third trimester. [1-3] Acute pancreatitis is classified into mild, moderate, and severe forms. Mild and moderate forms are the most common presentations, and the established guidelines recommend cholecystectomy during the same admission in non-pregnant patients with gallstone-induced pancreatitis. [4] However, for patients who develop severe acute biliary pancreatitis, especially with necrotizing pancreatitis, the decision regarding the timing of cholecystectomy is a complex one and prolongs the treatment process. On Objectives: Gallbladder stones are the most frequently reported etiology of acute pancreatitis in pregnancy and are often diagnosed in the third trimester. This condition is associated with both mother and infant morbidity and mortality, and its treatment remains controversial. Methods: Relevant patient data between September 2010 and April 2017 from the Kanuni Sultan Suleyman Training and Research Hospital were analyzed regarding etiology (of gallstone pancreatitis), trimester of pregnancy, diagnostic tools, pancreatitis stage, clinical status, medical treatment, surgical interventions, and pregnancy status. Results: We included 68 patients recorded with acute pancreatitis due to biliary gallstones. Pancreatitis symptoms developed in most (n=38) (55.8%) patients during the third trimester. Of 24 patients who had their first episode of pancreatitis in the first trimester of pregnancy, 12 (50%) were readmitted due to recurrence. Seven (11.3%) patients whose Ranson scale score was 3 underwent computed tomography evaluation. The number of patients with acute cholecystitis with pancreatitis was 5 (7.3%), whereas the number of patients with choledocholithiasis was 4 (5.8%). Sphincterotomy with endoscopic retrograde cholangiopancreatography was performed in 2 (2.9%) patients. Laparoscopic cholecystectomy was performed in 9 (13.2%) patients during pregnancy. No fetal and maternal morbidity and mortality was found in all periods. Conclusion: Developments in supportive care, widespread use of imaging methods, and a multidisciplinary approach with better antenatal care of pregnant patients with acute pancreatitis can help prevent fetal and maternal morbidity and mortality in such cases. Early laparoscopic cholecystectomy should be considered especially in pregnant patients with acute pancreatitis due to gallstones in the first trimester.
