i.e., the pancreatic region cannot be assessed because the view is blocked by gastrointestinal air

or, the pancreatic region cannot be assessed due to the interposition of gastrointestinal air

or, the pancreatic region cannot be assessed as it is obscured by gastrointestinal air

For example:

"Isolated pancreatic injury is rare, occurring in 0.2-12% of blunt trauma victims. Causes of pancreatic injury in this setting include a direct blow to the abdomen, falling across a rigid object with impact to the upper abdomen or seatbelt related injuries. Serum and urinary amylase levels are neither sensitive nor specific in diagnosing pancreatic injury.
****US is not useful in the evaluation of pancreatic injuries, in most series pancreatic injuries were not visualized due to interposition of air.***"
