Abstract

Background/Aims:
Pancreas divisum is a congenital anomaly caused by failure of fusion of the ventral and dorsal pancreatic anlagen during the sixth and seventh week of gestation. With widespread use of endoscopic retrograde cholangiopancreatography(ERCP), pancreas divisum is being detected with increasing frequency. Pancreas divisum is the most common congenital pancreatic anatomic variant, occuring in approximately 4.7 - 14% of necropsy series and has been demonstrated 1.3-6.7% of patients undergoing ERCP, The condition is seen least frequently in Asian(1-2%). It has been postulated that this anomaly may be a cause of obstructive pancreatic pain and pancreatitis on the basis of impaired drainage through the minor papilla. But there is a controversy as to whether pancreas divisum is associated with an increased incidence of pancreatitis. This study is performed to evaluate the clinical presentation and significance of pancreas divisum.
Methods:
27 cases of pancreas divisum detected among 1,718 ERCP examinations performed from June, 1993 to December, 1996 at our institution were critically analyzed.
Results:
Overall incidence of pancreas divisum was 1.6%. Among them, 13 cases(48.1%) were classified as complete type, 14 cases(51.9%) were classified as incomplete type. There was a significantly high incidence of pancreatitis, 22.2% in pancreas divisum compared with 5.6% in fused pancreas. Pancreas divisum was misdiagnosed as pancreatic head mass on radiological imaging study in 4 cases(25%).
Conclusions:
Pancreas divisum may be predispose to development of pancreatitis, and that its presence may lead to misinterpretation of ultrasonographic and CT scan findings.(Korean J Gastrointest Endosc 17: 624-631, 1997)
