[The left lateroportal lamina of the pancreas or left retropancreatic lamina]

Abstract

Findings on 100 cadaver dissections after lymphatic injections of fetuses and infants demonstrated the presence of the left posterior attachment of the pancreas corresponding to the left mesopancreatico-duodeno-umbilical contingent described by Couinaud. In adults, this hand, known initially as the left lateroportal process in no way constitutes a surgical obstacle to excision, but its pathologic role and embryologic significance cannot be disputed. As a result of the article by H. Richelme, the author is in entire agreement with the term left retropancreatic process.
