| 1 | Predictors of suboptimal bowel preparation in asymptomatic patients undergoing average-risk screening colonoscopy显示文摘AIM To identify risk factors for a suboptimal preparation among a population undergoing screening or surveillance colonoscopy.METHODS Retrospective review of the University of Michigan and Veteran's Administration(VA) Hospital records from 2009 to identify patients age 50 and older who underwent screening or surveillance procedure and had resection of polyps less than 1 cm in size and no more than 2 polyps. Patients with inflammatory bowel disease or a family history of colorectal cancer were excluded. Suboptimal procedures were defined as procedure preparations categorized as fair, poor or inadequate by the endoscopist. Multivariable logistic regression was used to identify predictors of suboptimal preparation.RESULTS Of 4427 colonoscopies reviewed, 2401 met our inclusion criteria and were analyzed. Of our population, 16% had a suboptimal preparation. African Americans were 70% more likely to have a suboptimal preparation(95%CI: 1.2-2.4). Univariable analysis revealed that narcotic and tricyclic antidepressants(TCA) use, diabetes, prep type, site(VA vs non-VA), and presence of a gastroenterology(GI) fellow were associated with suboptimal prep quality. In a multivariable model controlling for gender, age, ethnicity, procedure site and presence of a GI fellow, diabetes [odds ratio(OR) = 2.3; 95%CI: 1.6-3.2], TCA use(OR = 2.5; 95%CI: 1.3-4.9), narcotic use(OR = 1.7; 95%CI: 1.2-2.5) and Miralax-Gatorade prep vs 4L polyethylene glycol 3350(OR = 0.6; 95%CI: 0.4-0.9) were associated with a suboptimal prep quality. CONCLUSION Diabetes, narcotics use and TCA use were identified as predictors of poor preparation in screening colonoscopies while Miralax-Gatorade preps were associated with better bowel preparation. | Shail M Govani Eric E Elliott Stacy B Menees Stephanie L Judd Sameer D Saini Constantinos P Anastassiades Annette L Urganus Suzanna J Boyce Philip S Schoenfeld | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，17： | 7 |
| 2 | Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality. | Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim | 2009 | World Journal of Gastroenterology2009，15，11： | 4 |
