Migraine Classical migraine has an aura (a prodrome of symptoms such as ashing lights) lasting up to an hour preceding the onset of pain, frequently accompanied by nausea and vomiting.

Associated autoimmune pancreatitis with inflammatory masses, and associated weight loss, can sometimes make this difficult to differentiate from malignancy. Neoplasia Benign tumors (adenomas, papillomas, cystadenomas) are rare causes of mechanical biliary obstruction. Ampullary adenocarcinomas should be considered for a Whipples pancreaticoduodenectomy. The most common malignant stricture of the bile duct is due to invasion from to pancreatic cancer. Cholangiocarcinoma, the most frequent primary biliary tract malignancy, is rather uncommon in the Western world. There may be a deep-seated, vague discomfort - a feeling of fullness localized in the right upper quadrant of the abdomen. A distended, non-tender gallbladder may rarely be palpated, feeling like a small rubber ball, if the common duct is obstructed below the insertion of the cystic duct (Courvoisiers sign). For hilar/intrahepatic tumors, surgical decisions are more complicated and depend on stage (like vascular and bilateral liver involvement). If non-invasive imaging reveals a resectable non-hilar lesion in a young surgical candidate, it may be reasonable to go straight to surgery avoiding stenting, but generally a tissue diagnosis is pursued preoperatively in most patients. Palliation of distal tumors using biliary stents placed across strictures helps improve quality of life via alleviating jaundice, pruritus. Plastic stents are removable/exchangable but occlude after an average of 3-4 months, whereas self-expandable metal stents (both removable and non-removable varieties now available) can last longer (6-12 mos), but are much more costly (5-10 times). Hilar tumors are managed differently (both surgically and endoscopically) and should be suspected when the characteristic painless jaundice of cholangiocarcinoma occurs in the presence of intrahepatic biliary dilatation, but without extrahepatic biliary dilatation. Shaffer 582 non-invasive and quite accurate at staging these tumors (Bismuth classification) and determining their resectability. Draining one lobe is often sufficient for palliation although occasionally both sides may require drainage, especially if both sides are contaminated with dye at a procedure, or if cholangitis develops after stenting one side. Aantomy The pancreas is located retroperitoneally in the upper abdomen overlying the spine and adjacent structures, including the inferior vena cava, aorta and portal vein and parts of their major tributaries. Its retroperitoneal location makes the pancreas relatively inaccessible to palpation. The head and unci- nate process lie within the curvature of the duodenum, while the body and tail extend to the hilus of the spleen. The arterial supply of the pancreas is from the major branches of the celiac artery, including the splenic and gastroduodenal arteries, and the superior mesenteric artery, as well as an arborization of smaller branches (i. The pancreas does not have a capsule, and therefore pancreatic cancer often invades vascular structures, particu- larly the superior mesenteric vessels located directly posterior to the angle between the head and body of the pancreas. Nervous supply comes from parasympathetic branches of the vagus nerve, which provide a major secre- tory stimulus, and the sympathetic branches of the intermediolateral column of the thoracic spinal cord.
