“…However, patients with pancreas divisum and/or ansa pancreatica would hypothetically have an inadequate drainage of the pancreatic duct system and consequently have a relative increase of intraductal pressure into the main pancreatic duct. This has been suggested as a causative factor of pancreatitis (6,7).…”

Endoscopic treatment of pancreatic ductal malformations causing recurrent acute pancreatitis, such as pancreas divisum or ansa pancreatica, is mainly based on the sphincterotomy of the minor papilla. However, the technical complexity of conventional endoscopic retrograde cholangiopancreatography (ERCP) is increased in patients presenting anatomical variants like these and it may be unsuccessful. We report the case of a pancreas divisum combined with ansa pancreatica and describe the cannulation and sphincterotomy of the minor papilla using an ultrasound-assisted Rendez-Vous technique.

“…Since it was first reported by Dawson and Langman in 1961, there have been case reports and series on ansa pancreatica [ 39 - 41 ]. Many studies have hypothesized ansa pancreatica as a risk factor for acute pancreatitis [ 40 , 41 ]. This hypothesis is supported by the findings of a recent case-control study which reported a significantly higher risk of recurrent acute pancreatitis in individuals with ansa pancreatica [ 39 ].…”

Endoscopic retrograde cholangiopancreatography (ERCP) is an important diagnostic and therapeutic procedure in the management of biliary and pancreatic disorders. Despite advances in ERCP facilities and techniques, pancreatitis remains the most common and feared complication of this procedure. The technical challenges of ERCP could be further compounded by variations in the configuration of the pancreatic ductal system. As a result, the knowledge of these variations and their potential role in the development of post-ERCP pancreatitis (PEP) is essential to any successful risk reduction strategy. This review provides an overview of the anatomy and embryological basis of pancreatic duct variations, as well as explore the different types and prevalence of these variations. Also, we discuss the mechanisms of PEP and provide evidence supporting a link between the variations and PEP using published data

“…There have only a few articles exploring the ansa pancreatica and recurrent/chronic pancreatitis, thus ansa pancreatica is an under-reported disease entity (1,(3)(4)(5)(6)(7)(8). As comprehensive evaluation of the pancreatic duct variation by imaging such as computed tomography (CT) or magnetic resonance cholangiopancreatography (MRCP) is extremely important in order to correctly guide the next management steps, radiologists should be aware of this rare disease entity.…”

Ansa Pancreatica-Type Anatomic Variation of the Pancreatic Duct in Patients with Recurrent Acute Pancreatitis and Chronic Localized Pancreatitis

Ansa pancreatic is a rare variation of pancreas duct. Ansa pancreatica is characterized by focal accessory duct atrophy and an additional curved duct linking main and accessory ducts replacing atrophied duct. Ansa pancreatica is considered as a predisposing factor of recurrent pancreatitis. Pancreatitis can be localized in pancreas head and uncinate process, because pancreas head and uncinate process might be drained through the additional hooked duct of ansa pancreatica. We reports three cases of localized chronic or recurrent pancreatitis cases with underlying ansa pancreatica type anatomic variation.
