Terrie botones se encuentran debajo. When the history and physical examination suggest the possibility of pancreatic cancer, the first diagnostic test the authors use a spiral computed tomography CT scan.
If a pancreatic mass is detected, then the patient is evaluated for operation. If the ERCP demonstrates normal pancreatic and common bile ducts, then the patient may be observed with close follow-up.

If the duct anatomy is abnormal, then courvoisir patient is evaluated for operation. Some endoscopists may also obtain endoscopic needle aspiration or duct brushings at this point as well.
Patients are evaluated for operation on the basis of CT evidence for resectability and presence of metastases. If the CT scan demonstrates metastases or definite involvement of the major vessels eg, portal vein or superior mesenteric artery by tumor, the patient’s diseases are classified as key. Other factors that may influence whether or not a patient is an operative candidate are their ages and general overall medical condition. In patients determined to be candidates for operation, the use of laparoscopy as a first step is controversial.
Advocates perform laparoscopy to determine if there are any peritoneal ds liver metastases present that were not detected by the CT scan.

If metastases are present, laparotomy is avoided and the patient may undergo endoscopic stenting. If no metastases are detected by laparoscopy, the patient will undergo laparotomy.
Intraoperative determination of resectability will then determine whether or not the patient is a candidate for a resection of the tumor or a palliative bypass procedure. If a patient is not an operative candidate, tissue confirmation of pancreatic cancer is the next step; this is done coirvoisier CT- or ultrasound-guided tegrier aspiration FNA.

Endoscopic FNA, biopsy, or brushings are also options. If the biopsy is positive, then the patient can undergo endoscopic stenting or be reevaluated for a palliative bypass. If the biopsy is negative, the patient can undergo laparoscopy and biopsy. Guayacos, Anemia, hipoprot Marcadores Tumorales: Barium studies of the gastrointestinal GI tract are not often used to evaluate patients with suspected pancreatic cancer.
Because many of these patients present with nonspecific gastrointestinal symptoms, however, an upper GI may be obtained. Findings on upper GI that suggest pancreatic cancer include extrinsic compression, displacement or encasement of the C-loop, mucosal invasion nodularity or spiculationor Frostberg’s reversed “3” sign.
A, Widened duodenal sweep and the suggestion of compression of part of the duodenal loop. B, Note the reversed “3” sign caused by the nodular compression of the medial duodenal wall by the pancreatic cancer.
Ultrasound can be a useful diagnostic modality to evaluate a patient with jaundice of unknown etiology. If the cause of the jaundice is biliary obstruction from a pancreatic tumor, the extra- and intrahepatic bile ducts are dilated.
If the cause of the jaundice is intrahepatic, the ducts are of normal diameter. Ultrasound is inferior to computed tomography scanning both for tumor detection and staging of the disease. It is therefore not recommended for screening if pancreatic cancer is strongly suspected. B, Atypical cells, as seen on this CT-guided needle aspiration sample, signify the presence of pancreatic carcinoma.
This procedure plays an important role in patients who are not operative candidates either because their tumors are not resectable or they are in poor medical ee. Confirmation of pancreatic teerrier with tissue involvement can initiate palliative procedures, such as endoscopic stenting, chemotherapy, or reevaluation for an operative bypass.
B, Massive intrahepatic biliary dilatation secondary to obstruction of the common bile duct resulting from the pancreatic tumor. B, Endoscopic retrograde cholangiopancreatography in the same patient showing a stricture between arrows in the pancreatic duct with significant distal pancreatic duct dilatation. B, Close-up view demonstrates adherence of the mass to courboisier splenic vein.
