Gastric ectopic pancreas is an uncommon developmental anomaly and its histological diagnosis is usually difficult by using a conventional biopsy forceps. In the literature, most cases of gastric ectopic pancreas were usually diagnosed by gross pattern during endoscopic examination or features of endoscopic ultrasound. In contrast, this disease was seldom diagnosed by histology in clinical pract...

BACKGROUND/AIMS Endoscopic papillectomy is increasingly performed with curative intent for benign papillary tumors. This study was performed to identify factors that predict the presence of malignancy and affect endoscopic success. METHODS We retrospectively analyzed the medical records of patients who received an endoscopic papillectomy for papillary adenoma from 2006 to 2009. RESULTS A to...

PURPOSE As endoscopic treatment for vesicoureteral reflux (VUR) has increased, secondary ureteral reimplantation (UR) after failure of endoscopic treatment has increased. We studied the clinical feature and efficacy of secondary UR after failure of endoscopic treatment compared with primary UR. MATERIALS AND METHODS Eighty-one children who had UR for VUR were enrolled. Charts were reviewed re...

Objectives: To investigate clinicopathologic findings and gallbladder (GB) function in patients with endoscopic bile reflux at outpatients clinic. Methods: We classified endoscopic bile reflux into two groups by bile reflux index (BRI). Those who scored above 14 were the BRI (+) group, and those below 14 were the BRI (-) group. We analyzed clinical characteristics, endoscopic findings including...

INTRODUCTION accurate preoperative localization of colorectal cancer (CRC) is very important, with a wide range of published error rates. AIMS to determine accuracy of endoscopic localization of CRC in comparison with preoperative computed tomography (CT). To analyse variables that could be associated with a wrong endoscopic localization. PATIENTS AND METHODS endoscopic and CT localization ...

The aim of the Endoscopic Retrograde Cholangiopancreatography (ERCP) Working Group was to examine the issues of training, credentialing and quality control in ERCP in Singapore. Published guidelines and clinical trials concerning issues of training, complications and quality control in ERCP have been reviewed. The Working Group recommended that a trainee reach a minimum threshold of 200 cases b...

Colorectal adenomas are well known precursors of invasive adenocarcinoma. Colonoscopy is the gold standard for adenoma detection. Colonoscopy is far more than a diagnostic tool, as it allows effective treatment of colorectal adenomas. Endoscopic resection of colorectal adenomas has been shown to reduce the incidence and mortality of colorectal cancer. Difficult resection techniques are availabl...

We review the current state of research in endoscopic optical coherence tomography (OCT). We first survey the range of available endoscopic optical imaging techniques. We then discuss the various OCT-based endoscopic methods that have thus far been developed. We compare the different endoscopic OCT methods in terms of their scan performance. Next, we examine the application range of endoscopic ...

Endoscopic treatment can be a curative option for small carcinoid tumors with an extremely low risk of metastasis. Since most carcinoid tumors are characterized by a specific growth pattern in the submucosal (SM) layer, specialized endoscopic techniques for deeper resection to achieve clear vertical margins are needed. The endoscopic submucosal dissection (ESD) method in the SM space is superio...
