Final answer:
The dissection technique used to inspect the duodenum, pancreas, and other retroperitoneal structures by mobilizing the duodenum is called the Kocher maneuver.
Step-by-step explanation:
The dissection of the lateral peritoneal attachments of the duodenum to allow inspection of the duodenum, pancreas, and other retroperitoneal structures is called Kocher maneuver. This technique involves mobilizing the duodenum by incising its peritoneal attachments, which then allows the duodenum and the head of the pancreas to be inspected more easily. This can be important for surgical procedures that need access to these structures, such as the removal of pancreatic tumors, as well as to facilitate certain diagnostics and repair procedures.
