Which symptom is NOT an indication for a sonogram of the pancreas?

Flank pain is generally associated with conditions affecting the kidneys or structures in the retroperitoneal space rather than the pancreas. While flank pain can indicate various issues, it is not a typical symptom prompting a sonogram specifically for pancreatic evaluation.

In contrast, other symptoms like biliary disease, weight loss, and severe epigastric pain are more directly related to pancreatic issues. Biliary disease can lead to complications with the pancreas, such as pancreatitis, where the relationship between the biliary system and the pancreas becomes significant. Weight loss can occur in the presence of pancreatic cancer or chronic pancreatitis due to malabsorption. Severe epigastric pain is a classic symptom of acute pancreatitis or pancreatitis-related conditions; thus, these symptoms warrant further investigation with a sonogram of the pancreas.
