29 Μαΐ 2023 · Annular pancreas (AP) is a rare congenital anomaly characterized by partial or complete circumferential encasement of the second part of the duodenum by a band of pancreatic tissue during embryogenesis.
14 Αυγ 2023 · Annular pancreas occurs when pancreatic tissue circumferentially covers the second part of the duodenum. During embryogenesis, growth of the hepatic bud normally lifts the ventral pancreas away from the developing foregut tube.
8 Μαΐ 2024 · EMBRYOLOGY AND PATHOGENESIS. The pancreas develops from the dorsal and ventral pancreatic buds that first appear as evaginations of the primitive foregut at around the fifth week of gestation.
The annular pancreas remains an intriguing congenital anomaly. Many theories have sought to explain its embryological basis; however, no consensus has yet been reached regarding the exact mechanism of aberration.
1 Σεπ 2012 · Therefore, the objective of this review is to provide an up-to-date report of the embryological, molecular and genetic origins of annular pancreas as well as outline its clinical presentation, diagnosis and treatment.
1 Σεπ 2012 · Annular pancreas is a relatively rare congenital anomaly (Ravitch and Woods, 1950). It is characterized by an extension of pancreatic tissue around the second part of the duodenum and is thought to represent aberration in the development of the ventral pancreatic bud (Choi et al., 2004).
24 Νοε 2020 · Annular pancreas is an embryological defect of the foregut. Development of the pancreas begins during the fifth week of gestation. One dorsal and two ventral buds develop from the primitive foregut.
