BACKGROUND Endoscopic sclerotherapy (ES) and band ligation are standard treatments for esophageal varices. Unfortunately, recurrence is common and seems to be related to esophageal collateral vessels, easily identified by EUS. Eradication of these vessels might lead to a more durable therapeutic effect. OBJECTIVE To compare ES with EUS-guided(More)
CONTEXT Pseudotumoral chronic pancreatitis can be difficult to differentiate from pancreatic carcinoma. OBJECTIVE To evaluate the role of endoscopic ultrasound and fine needle aspiration in differentiating between inflammatory masses and malignancies in chronic pancreatitis. DESIGN Retrospective study. SETTING Tertiary care endoscopy unit. PATIENTS(More)
Botulinum toxin (BT) has recently been indicated as an alternative treatment of idiopathic achalasia with a success rate of 60-70%. One-third of BT-treated cases either fail to respond or fail to sustain the response beyond 6 months. An explanation for BT therapeutic failure would be that the lower esophageal sphincter muscular layer (LES) may be missed as(More)
BACKGROUND The use of EUS for precise preoperative evaluation of pancreatic neuroendocrine tumors is well established; up to 80% of insulinomas can be localized. However, the EUS appearance of pancreatic neuroendocrine tumors can be similar to that of benign peripancreatic lymph nodes. The aim of this study was to evaluate the role of EUS-guided FNA in this(More)
INTRODUCTION Necrosectomy is the gold standard treatment for infected pancreatic necrosis (IPN). A percutaneous and endoscopic approach has been accepted in selected cases. Endoscopic drainage (ED) of IPN can be performed by using transpapillary or transmural procedures, or a combination of both with or without endoscopic ultrasound. AIMS The aim of this(More)
OBJECTIVE Surgery is the treatment of choice for traumatic pseudocyst. Minimally invasive management of these collections has been used. The aim was to analyze the outcome after endoscopic treatment and the integrity of the main pancreatic duct caused by abdominal trauma. METHODS A total of 51 patients with traumatic pseudocyst who underwent endoscopic(More)
BACKGROUND Preoperative radiologic localization of insulinomas often fails because of the small size of these tumors. Endoscopic ultrasound (EUS) can localize insulinomas in up to 80% of the cases. The aim of this study was to compare EUS and computed tomography (CT) diagnostic accuracy for insulinomas. METHODS We reviewed medical records from 12 patients(More)
Cytological smear is widely employed to analyse specimens obtained from endosonography-guided fine-needle aspiration (EUS-FNA), but false-negative or inconclusive results may occur. A better diagnostic yield can be obtained from processing cell blocks. We compared the effectiveness of the cell block technique and cytological smear in the diagnosis of(More)
BACKGROUND Metastases to the pancreas are rare, and usually mistaken for primary pancreatic cancers. This study aimed to describe the histology results of solid pancreatic tumours obtained by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for diagnosis of metastases to the pancreas. METHODS In a retrospective review, patients with(More)
