background: endoscopy of the upper gastrointestinal tract is the most accurate method for the diagnosis of most disease conditions associated with dyspepsia. however, endoscopy involves some discomfort, significant social inconvenience, and cost. attempts to identify those patients most likely to benefit from endoscopy have met with variable success. to evaluate endoscopic findings of the upper...

conclusions there were 80 (17.90%) patients receiving endoscopic hemostatic therapy. in children with ugib, upper endoscopy is a diagnostic procedure for the categorization of underlying causes of upper gastrointestinal bleeding in children and various endoscopic lesions may be found in a patient with the impression of ugib. background upper gastrointestinal (ugi) endoscopy is a tool used frequ...

Endoscopic resection is the established treatment for early gastric cancer in selected patients with negligible risk of lymph node metastasis ('absolute indication'). Based on clinical observations and large pathological databases, expanding indications for endoscopic resection beyond absolute indication has been tried in Japan and Korea. However, controversies exist regarding the safety of tre...

BACKGROUND/AIMS In recent years, endoscopic snare papillectomy has been performed to treat tumors of the ampulla of Vater. This procedure requires accurate preoperative evaluation. In this study, we diagnosed the focal extension of such tumors by using endoscopic ultrasonography (EUS) and intraductal ultrasonography (IDUS), and examined the indications for endoscopic snare papillectomy. METHO...

IntroductIon Endoscopic ultrasonography (EUS) and EUSguided fine-needle aspiration (EUS-FNA) are now well-established modalities in the evaluation of mediastinal and abdominal lesions. In the thorax, EUSFNA has been repeatedly demonstrated to be effective in the diagnosis and staging of esophageal and lung cancer as well as the evaluation of lymphadenopathy.1 Several case reports have shown EUS...

CONTEXT Appropriate surgical exploration and resection of pancreatic carcinoma depends on accurate preoperative evaluation. OBJECTIVE Determine the accuracy of endoscopic ultrasound in predicting the need for surgical exploration in patients with solid pancreatic masses deemed by computer tomography to be resectable without venous grafting (absence of distant metastatic disease or major vascu...

OBJECTIVES Many factors influence the outcome of endoscopic dacryocystorhinostomy (DCR). One of the most important prognostic factors is the level of obstruction in the lacrimal drainage system. The main objective of this report is to evaluate both the frequency of obstruction by anatomical region of the lacrimal drainage system on dacryocystography (DCG) and the surgical outcome of endoscopic ...

Endoscopic endonasal transsphenoidal approach to the sellar region yields an alternative to classical microsurgical approaches. Endoscopes provide images that differ from microscopic view. This study aimed to highlight surgical landmarks and their anatomical relationships for pituitary surgery through endoscopic perspective. Ten sides of five adult cadaveric heads with red-colored latex injecte...

BACKGROUND Diagnosis of pancreatic lesions can be accurately performed by endoscopic ultrasound guided fine needle aspiration (EUS-FNA) with onsite cytopathologists to assess specimen adequacy and to determine a preliminary diagnosis. Considerable time is needed to perform on-site assessments. This takes away work time of cytopathologists and prohibits them from serving remote locations. It is ...

Cytomegalovirus (CMV) is responsible for the most common opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS). The colon is a common site for these infections in patients positive for human immunodeficiency virus. CMV rarely presents as an intraluminal inflammatory mass in the colon. Here we report the case of a CMV infection presenting as a mass-like lesion in an...
