Abstract.Background: We evaluated the usefulness of endoscopic ultrasonography for detecting pancreatobiliary carcinoma and assessing portal venous invasion by carcinoma. Methods: Seventy-three patients with pancreatic carcinoma (54 patients) or bile duct carcinoma (19 patients) underwent endoscopic ultrasonography, transabdominal ultrasonography, computed tomography (CT), and angiography. All patients underwent tumor resection and histological examination for portal venous invasion. Results… 

Role of computer tomography and endoscopic ultrasonography in assessing portal and superior mesenteric vessels invasion in cephalo-pancreatic adenocarcinoma.

Both types of examination have showed good accuracies in diagnosing vascular invasion separately and a combination of the two may be used when the CECT result is uncertain as it provides a higher chance of a correct diagnosis.

Role of Endoscopic Ultrasonography in the Management of Malignant Pancreatico-biliary Disease

With the continuing improvement of EUS and the development of accessories, EUS plays a more important role as an interventional modality for tumor ablation and management of tumor-associated complications.

Role of Endoscopic Ultrasonography and Endoscopic Retrograde Cholangiopancreatography in the Diagnosis of Pancreatic Cancer

ERCP is essential in cases that require evaluation of pancreatic duct stricture that may be early pancreatic cancer or those that require differentiation from focal autoimmune pancreatitis, and is an essential examination method for the definitive pathological diagnosis and treatment decision strategy.

Utility of contrast-enhanced harmonic EUS for diagnosis of portal vein invasion by pancreatic cancer

CH-EUS is useful for diagnosis of portal vein invasion by pancreatic cancer, and EUS and CE-CT were comparable in this single-center, retrospective study.

Evaluation of Resectability for Pancreatic Cancer Using Endoscopic Ultrasound

EUS can also serve as an alternative to conventional percutaneous ultrasonography and biopsy for identification of liver metastases and a cyto-pathological diagnosis via EUS-guided fine needle aspiration (EUS-FNA) is highly accurate.

Utility of convex EUS for preoperative vascular evaluation of malignant biliary tract neoplasm.

Overall, convex EUS is useful for the preoperative evaluation of malignant biliary tract neoplasms, and surgery may be considered when the tumor is close to the HA on computed tomography scans, however there is no obvious encasement visualized by convexEUS.

Impact of endoscopic ultrasonography on diagnosis of pancreatic cancer

Conventional EUS, CE-EUS, EUS elastography, and EUS-FNA are essential in the clinical investigation of pancreatic cancer.

Role of Endoscopic Ultrasonography in the Evaluation of Extrahepatic Cholangiocarcinoma

Endoscopic ultrasound (EUS) is a diagnostic modality which may overcome the limitations of other imaging and biopsy techniques in this setting and complement the role of ERCP and provide a tissue diagnosis through fine needle aspiration (FNA) and staging through ultrasound imaging.

Current status on the diagnosis and evaluation of pancreatic tumor in Asia with particular emphasis on the role of endoscopic ultrasound

Endoscopic ultrasonography (EUS) offers a higher sensitivity (93–100%) for detection of small potentially curable pancreatic masses than other existing imaging modalities and enables the performance of endoscopic interventions.

The value of endoscopic ultrasonography for differential diagnosis in obstructive jaundice of the distal common bile duct

The value of endoscopic ultrasonography in the etiological diagnosis, relevant treatment applications of distal obstructive jaundice and the limitations of endoscopy in some etiologies are summarized due to the lack of clear comparison with other imaging methods are summarized.



Comparison of angiography and ultrasound in the evaluation of the portal venous system in pancreatic carcinoma

Ultrasound can make angiography prior to laparotomy unnecessary in many cases if thorough evaluation of the portal venous system is emphasized during the initial ultrasound study.

Endoscopic ultrasonography in the diagnosis and staging of pancreatic adenocarcinoma. Results of a prospective study with comparison to ultrasonography and CT scan.

Endoscopic ultrasonography is an accurate tool for diagnosis and locoregional spread assessment of pancreatic cancer when performed in a reference center, however, EUS does not enable differentiation of pseudotumorous pancreatitis from adenocarcinoma.

Comparison of CT and angiography in assessing resectability of pancreatic carcinoma.

CT is about as accurate as angiography in assessing resectability of pancreatic carcinoma, but several other patients were found to have liver metastases, resulting in a radiologic diagnosis of nonresectability in 20 patients overall.

Surgical indication and significance of portal vein resection in biliary and pancreatic cancer.

Tumor and vascular resection was carried out in 27 patients with biliary and pancreatic cancer, and forty-seven percent of the patients who had no lymph node metastasis or peritumor lymph nodes metastasis without cancerous invasion of the portal vein intima survived more than 2 years.

Computed tomographic appearance of resectable pancreatic carcinoma.

Thirteen patients with resectable pancreatic carcinoma were examined by computed tomography (CT) and a small cancer without change in pancreatic contour is difficult to detect with CT.

Efficacy of computerized tomography in the preoperative staging of pancreatic carcinoma.

Therapeutic decisions for nonoperative management of patients with pancreatic cancer based upon CT predictions of unresectability solely on the basis of locally advanced disease, can not be recommended at this time.
