The Epidemiology and Clinical Presentation of Pancreatic Divisum: A Case Series of 57 Case Reports
Abstract
Objectives: Pancreatic divisum (PD) is the second most common congenital abnormality of the pancreatic duct, which affects 2% to 3% of the population. Most of the population remains asymptomatic, but in people who present with symptoms, it can be a cause of anguish and should be recognized. The main goal of this article was to provide a comprehensive picture of clinical and epidemiological methods of diagnosis and treatment of PD.Methods: A total of 57 PD case reports were considered in this descriptive analysis with 51 case reports and case series published within the last 25 years. The search strategies include systemic searches using scholarly search engines such as Medscape, Scopus, Cochrane, and PubMed.
Results: The 57 cases we studied have an average age of presentation of 42 years, with female sex (58%) predominance. Common presenting symptoms were abdominal pain (87.72%) and radiation to the back (21.6%). Eighty-one percent of the case studies reported pancreatitis, and 63.2% had recurrent pancreatitis. At presentation, laboratory values demonstrated increased amylase, lipase, and liver enzymes. PD was diagnosed using magnetic resonance cholangiopancreatography (28.1%), endoscopic retrograde cholangiopancreatography (57.9%), endoscopic ultrasound (7%), or computed tomography (5.3%) scan of the abdomen. Of significance, biliary duct dilation was found in 70.6% of patients diagnosed as having PD. Incidental masses were found in 66.7% of the patients. The most successful treatment was sphincterotomy with or without stents (47.6%), followed by pancreatoduodenectomy (19%) and pancreaticojejunostomy (10%).
Conclusions: Physicians managing pancreatitis should add PD to their differential diagnoses because it will help improve patient outcomes and avoid unfavorable consequences.
