Although the incidence of perforation after endoscopic procedures of the colon is low, the rising number of diagnostic colonoscopies could pose relevant health problems. Optimizing treatment may reduce the probability of severe complications. This study aimed to determine perforation frequency and the management of perforations that occurred during(More)
BACKGROUND Various training programs in colonoscopy recommend that trainees should perform at least 100 to 200 procedures to be considered technically competent at diagnostic colonoscopy. OBJECTIVE Our purpose was to determine the adequate level of training for technical competence in screening and diagnostic colonoscopy. DESIGN A prospective(More)
Myxedema ascites caused by hypothyroidism is rare, so its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a 71-yr-old man with clinical ascites that was the first manifestation of hypothyroidism, and which resolved completely in response to thyroid hormone(More)
BACKGROUND/AIMS Alterations of the expression pattern of mucins and trefoil peptides have been described in gastric adenocarcinomas and in their precursor lesions. The aim of this study was to determine the progression patterns of intestinal metaplasia (IM) subtypes by analyzing the expression patterns of TFF1 and MUC5AC in different subtypes of IM of the(More)
Gastric surgeries may predispose patients to the formation of gastric phytobezoars. Cola-lysis through nasogastric lavage, endosopic infusion and/or the oral intake of cola are recently introduced techniques for the dissolution of phytobezoars. However, their complications have rarely been reported. Herein, we report a 56-year-old woman, who had previously(More)
BACKGROUND/AIMS Techniques for endoscopic evaluation of gastrointestinal subepithelial lesions include conventional endoscopy, jumbo biopsy, endoscopic ultrasonogrphy (EUS), EUS-guided fine needle aspiration, and endoscopic submucosal resection. However, these procedures have many limitations, such as low diagnostic yields and high complication rates. We(More)
BACKGROUND AND AIM Whether concomitant therapy is superior to sequential therapy (ST) as first-line therapy of Helicobacter pylori in areas with high clarithromycin resistance remains controversial. The aim of this study was to compare the efficacy and tolerability of 10- or 14-day ST with 10- or 14-day concomitant therapy (CT). METHODS This was a(More)
BACKGROUND/AIMS The aim of this study was to determine whether the routine closure of mucosal defects after endoscopic submucosal dissection (ESD) can enhance mucosal healing and reduce ESD-associated bleeding. METHODS Patients with gastric epithelial neoplasias and no obvious submucosal invasion were prospectively enrolled. Mucosal defects were left(More)
BACKGROUND AND STUDY AIMS The effectiveness of the prophylactic clip for the prevention of postpolypectomy bleeding in pedunculated colonic polyps has not been confirmed. The aim of this prospective, randomized study was to compare the efficacy of prophylactic clip and endoloop application in the prevention of postpolypectomy bleeding in large pedunculated(More)
