..This case shows the need for adequate bowel preparation if cautery is to be used, even in patients who have undergone a colectomy...

..Studies published in radiology journals showed significantly stronger preference for CTC compared with studies in gastroenterology or general medicine journals...

..Perceptual and fatigue-related reading errors can potentially be minimized with the help of computer-aided detection software. Further research will define the exact role of this promising technology in our diagnostic armamentarium...

..A large controlled prospective observational study to compare pre- and postsurgery changes in reflux symptoms between cholecystectomy and hernia repair surgery patients...

..We developed a risk index to identify low-risk patients who may be screened for colorectal cancer with computerized tomographic colonography (CTC) instead of colonoscopy...

..Although the prevalence of colonic neoplasia increases with age, life expectancy decreases. Thus, the benefit of screening colonoscopy in very elderly patients may be limited...

..Our goal is to assess the risk of proximal neoplasia in asymptomatic patients with distal hyperplastic polyps, compared to those with distal tubular adenomas or no distal polyps...

..Practice patterns tend to be more aggressive than those recommended by recent guidelines and those reported by previous surveys. Medico-legal considerations affect practice substantially...

..Screening for hepatocellular carcinoma in cirrhotic patients using abdominal ultrasonography and alpha-foetoprotein levels is widely practiced...

..However, many studies have shown an increased risk of proximal neoplasia (PN) in patients with distal HPs. We performed a systematic review to assess the association between distal HPs and PN...

..More intensive colonoscopic surveillance should be considered for patients with ulcerative colitis and primary sclerosing cholangitis...

..Previous studies showed a correlation between mean withdrawal times during screening colonoscopy and polyp/neoplasia detection rates...

..A multicenter study found ECE to be safe, well tolerated, and accurate; however, a post hoc adjudication process was used that may have biased results...

..Endoscopic therapies for early neoplasia in Barrett's esophagus may be a viable alternative to esophagectomy...

..The other factors are supported by limited observational data only and are still controversial...

..There was no procedure-related complication. CONCLUSIONS: JC-EUS is safe, provides superior image quality to C-EUS, and is accurate for local staging of esophageal cancer...

..Many endoscopy units administer patient satisfaction surveys. We hypothesized that the survey collection method would affect satisfaction scores...

..Potential advantages for Barrett's esophagus (BE) screening include ability to return to work as a result of lack of intravenous sedation...

..Colonoscopy is safe, well-tolerated, and a viable screening option in Chinese patients, but its advantage over sigmoidoscopy as a screening tool may be smaller...

..In our case, endoscopic ultrasound showed a band of bright echogenicity arising from the submucosa layer, representing air in the gastric wall...

..The complication rate associated with monopolar coagulation was low...
