Fenrilar When the history and physical examination suggest the possibility of pancreatic cancer, the first diagnostic test the authors use a spiral computed tomography Enfemreria scan. B, Endoscopic retrograde cholangiopancreatography in the same patient showing a stricture between arrows in the pancreatic duct with significant distal pancreatic duct dilatation. If a patient is not an operative candidate, tissue confirmation of pancreatic cancer is the next cidados this is done using CT- or ultrasound-guided fine-needle aspiration FNA. 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 condition. If the duct anatomy is abnormal, then the patient is evaluated for operation.

If a patient is not an operative candidate, tissue confirmation of pancreatic cancer is the next step; this is done using CT- or ultrasound-guided fine-needle aspiration FNA. If the cause cujdados the jaundice is intrahepatic, the ducts are of normal diameter. If no metastases are detected by laparoscopy, the patient will undergo laparotomy.
If the cause of the jaundice is biliary obstruction from a pancreatic tumor, the extra- enfermeia intrahepatic bile ducts are dilated. Patients are evaluated for operation on the amiydalectomia of Cuicados evidence for resectability and presence of metastases.
If a pancreatic mass is detected, then the patient is evaluated for operation. If the biopsy is negative, the patient can undergo laparoscopy and biopsy. 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. Advocates perform laparoscopy to determine if there are any peritoneal or liver metastases present that were not detected by the CT scan.
B, Close-up view demonstrates adherence of the mass to the splenic vein. 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. B, Massive intrahepatic biliary dilatation secondary to obstruction of the common bile duct resulting from the pancreatic tumor.
If metastases are present, laparotomy is avoided and the patient may undergo endoscopic stenting. If the ERCP demonstrates normal pancreatic and common bile ducts, then the patient may be observed with close follow-up. B, Endoscopic retrograde cholangiopancreatography in the same patient showing a stricture between arrows in the pancreatic duct with significant distal pancreatic duct dilatation.
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. Miguel Moreno Sanfiel, Dr. 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 condition.
In patients determined to be candidates for operation, the use of laparoscopy as a first step is controversial. Confirmation of pancreatic cancer with tissue involvement can initiate palliative procedures, such as endoscopic stenting, chemotherapy, or reevaluation for an operative bypass. Ultrasound can be a useful diagnostic modality to evaluate a patient with jaundice of unknown etiology. It is therefore not recommended for screening if pancreatic cancer is strongly suspected.
A, Widened duodenal sweep and the suggestion of compression of part of the duodenal loop. Endoscopic FNA, biopsy, or brushings are also options.
Other factors that may influence whether or not a patient is an operative candidate are their ages and general overall medical condition. Sobre el proyecto SlidePlayer Condiciones de uso. If the biopsy is positive, then the patient can undergo endoscopic stenting or be reevaluated for a palliative bypass.
Ultrasound is inferior to computed tomography scanning both for tumor detection and staging of the disease. Livia de Rezende, Dr. TOP Related.
