Example text

Overall, CT is the best single imaging test to evaluate the pancreas and surrounding structures. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) can define subtle abnormalities of the biliary and pancreatic ducts and guide interventions to relieve obstruction from stones or strictures; 35 36 Part I Gastrointestinal however, these tests—particularly ERCP—are much more invasive than CT or US. Relative Costs: US, $$; CT, $$$; EUS, $$$; ERCP, $$$$. PLAN AND RATIONALE (A) MILD ACUTE PANCREATITIS STEP 1: ULTRASOUND (US) Generally, no imaging is required beyond abdominal US to exclude gallstones as a cause and to examine the bile ducts for obstruction (dilation).

The patient should fast for at least 4 to 6 hours before US, so that the gallbladder becomes distended with bile. The pancreas itself may appear normal sonographically or show very subtle peripancreatic inflammation in mild cases. Whereas the head and body of the pancreas are well seen with US, the pancreatic tail is often incompletely visualized because of overlying bowel gas. If gallstones are present, elective cholecystectomy is usually warranted, after the acute episode resolves, to prevent future episodes of pancreatitis or cholecystitis.

Relative Costs: Abdominal US, $$; abdominal CT, enhanced, $$$; ERCP, $$$–$$$$; endoscopic US, $$$; pancreatic biopsy, CT-guided, $$$–$$$$; pancreatic biopsy, US-guided, $$$–$$$$. 29 30 Part I Gastrointestinal PLAN AND RATIONALE For suspected pancreatic carcinoma in the jaundiced patient: STEP 1: ULTRASOUND (US) Pancreatic lesions producing jaundice are most likely in the pancreatic head. US defines pancreatic head tumors and often other causes of jaundice, such as a gallstone in the common bile duct or a tumor in the liver or porta hepatis.
