The aim of this study was to review the efficacy of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) in diagnosing gallbladder (GB)-protruded lesions. Thirty-eight patients underwent CH-EUS for the diagnosis of GB-protruded lesions. Twenty-four patients whose major axes of their largest lesions were longer than 10 mm were recruited. The ability of CH-EUS to diagnose malignant or b...

OBJECTIVE To evaluate the diagnostic utility of endoscopic ultrasound guided fine needle aspiration cytology in the diagnosis of mediastinal and abdominal lesions. METHODS Endoscopic ultrasound guided aspiration cytology was carried out on a total of 155 cases during the study period. The lesions were categorized according to the site of needle biopsy. Clinical impression and provisional diag...

BACKGROUND Puncture biopsy and fine needle aspiration guided by endoscopic ultrasound has been used as an effective technique and is quickly becoming the procedure of choice for diagnosis and staging in patients suspected of having pancreatic cancer. This procedure has replaced retrograde cholangiopancreatography and brush cytology due to its higher sensitivity for diagnosis, and lower risk of ...

Pancreatic cancer remains a devastating disease, with poor survival rates and high recurrence rates with current treatment regimens. Over the years we have come to understand the complex biology of this cancer, involving cross-talking signaling pathways that proffers resistance to current therapy. Several molecularly targeted agents remain in development. At the 2013 American Society of Clinica...

CONTEXT Endoscopic ultrasound-guided trucut biopsy (EUS TCB) has a lower yield than fine needle aspiration (FNA) in pancreatic masses but the additional use of TCB to FNA may improve the diagnostic accuracy over FNA alone. OBJECTIVE To compare the yield of EUS FNA alone or combined with EUS TCB for diagnosis of pancreatic masses. DESIGN Single center retrospective case control study conduct...

doscopic examination because of an episode of tarry stool. Her medical history was significant for chronic renal failure, for which she was receiving peritoneal dialysis. Upper endoscopy disclosed an ulcerative tumor in the gastric antrum (●" Fig. 1). The first biopsy from the ulcer displayed chronic inflammation. An abdominal computed tomography (CT) scan disclosed an hyperintense, homogeneous...

Objectives The Papanicolaou Society of Cytopathology’s terminology scheme for endoscopic ultrasound-guided fine needle aspiration cytology includes an ‘atypical’ interpretation category. We conducted a retrospective study to determine the frequency of its use within our institution and the interobserver agreement among pathologists with variable experience in interpretation. Methods Following I...

Strategies for the treatment of cancer of the oesophagus depend on the tumour stage at the time of diagnosis. Resection, the only curative treatment, is confined to early tumour stages. Tumours with local infiltration are usually unresectable and require palliative treatment. Computed tomography has been widely used for preoperative staging but often fails to define this correctly. Endoscopic u...
