Final answer:
This patient is likely experiencing a gallstone blockage in the bile duct, causing severe abdominal pain and jaundice. Treatment usually involves surgical removal of the gallbladder. An abdominal ultrasound can be used to confirm the diagnosis.
Step-by-step explanation:
This patient is a 48-year-old female presenting with abdominal pain, jaundice, and a history of biliary colic. Based on her symptoms and medical history, she is likely experiencing a gallstone blockage in the bile duct. Gallstones are solid particles formed from cholesterol that can obstruct the flow of bile and cause pain and jaundice. In this case, the gallstone blockage is causing her severe and steady pain in the epigastric region, which radiates to the tip of her right shoulder.
Treatment for gallstones usually involves surgical removal of the gallbladder, a procedure called cholecystectomy. This is done to prevent future gallstone related complications and relieve symptoms. If left untreated, a gallstone blockage can lead to inflammation of the pancreas, a condition called pancreatitis.
In order to confirm the diagnosis of gallstones and assess the severity of the blockage, an abdominal ultrasound can be performed.
