Congenital and Inherited Anomalies of the Pancreas

Management of gastric ectopic pancreas identified in preoperative evaluation of bariatric surgery – A case report

“…The most common location is in the stomach, particularly in the antrum. Other locations include the duodenum, jejunum, Meckel's diverticulum, ileum, liver, spleen, biliary tract, and the mesentery [ 1 ] among others. It is a rare lesion, occurring in 0.9% of gastrectomies [ 2 ] and 0.5% in bariatric surgeries [ 5 ].…”

“…It is a rare lesion, occurring in 0.9% of gastrectomies [ 2 ] and 0.5% in bariatric surgeries [ 5 ]. However, it has been observed that the lesion is not so uncommon in autopsies, with an incidence varying from 1 to 13% [ 1 ].…”

“…The pathogenesis remains unknown. There are theories that correlate the presence of EP to defects in the migration of pancreatic tissues; metaplasia from endodermal tissues in embryogenesis or genetic mutations [ 1 , 10 ].…”

“…The use of these criteria contributes to diagnostic differentiation between GEP and GIST. However, the definitive diagnosis is obtained through the anatomopathological study [ 1 ].…”

“…The ectopic pancreas (EP) is defined as pancreatic tissue without communication with the main pancreas and with an independent vascular and ductal supply [ 1 ]. It is a rare lesion, located mainly in the stomach, being known as Gastric Ectopic Pancreas (GEP), usually asymptomatic and of which treatment is surgical, due to the associated risks [ [2] , [3] , [4] ].…”
