Randomized Controlled TrialThe efficacy and safety of carbon dioxide insufflation during colonoscopy with consecutive esophagogastroduodenoscopy in moderately sedated outpatients: a randomized, double-blind, controlled trial.
Colonoscopy with consecutive esophagogastroduodenoscopy (CCEGD) can be more convenient than performing each procedure individually. There has been no randomized controlled trial comparing carbon dioxide (CO2) versus air insufflations during CCEGD in sedated patients. CO2 insufflation instead of air during CCEGD may reduce abdominal pain and be more comfortable. We investigated the efficacy and safety of CO2 insufflation during CCEGD in moderately sedated outpatients. ⋯ CO2 insufflation during CCEGD reduced postprocedural pain and distension compared with air. It was comfortable and safe to use in moderately sedated outpatients.

Use of administrative claims data for identifying patients with cirrhosis.
Administrative data are used in clinical research, but the validity of ICD-9 codes to identify cirrhotic patients has not been well established. ⋯ Administrative data can identify patients with cirrhosis with high accuracy, although ascites has a significantly lower positive predictive value than other ICD-9 codes.
