Pancreas divisum. A predisposing factor to pancreatitis?
Cases of pancreas divisum (PD) were reviewed in our patients and 19 Japanese and 14 English series during the past 10 yr to see any significant association of PD with certain diseases. PD was diagnosed in 20 (0.64%) among our 3121 patients with successful endoscopic pancreatograms (ERP). Of 20 PD patients, acute pancreatitis in one, chronic pancreatitis in two, ampullary cancer in one, and cholelithiasis in five were diagnosed. Incidences of PD were 2.6% (1/38) in acute pancreatitis, 0.8% (2/248) in chronic pancreatitis, 0% (0/100) in pancreatic cancer, 20% (1/5) in ampullary cancer, and 0.8% (5/615) in cholelithiasis. The incidences were similar to overall incidences of ours and other Japanese series (0.69% of 36,171 patients). Higher incidences of acute pancreatitis (12.9% of 559) and pancreatic cancer (5.5% in 448) may result from the higher overall incidence (4.6% in 16,257) in English series. The relationship between pancreatitis and PD has been controversial, but our present data suggest that PD is a coincidental finding and not a predisposing factor to pancreatitis in Japan.
