Journal ArticleDOI
Colonoscopic miss rates of adenomas determined by back-to-back colonoscopies.
Douglas K. Rex,Christopher S. Cutler,Gregory T. Lemmel,Emad Y. Rahmani,David W. Clark,Debra J. Helper,Glen A. Lehman,David G. Mark +7 more
TL;DR: Using current colonoscopic technology, there are significant miss rates for adenomas < 1 cm even with meticulous colonoscopy, and the results suggest the need for improvements in colonoscope technology.
Journal ArticleDOI
Screening for Barrett's esophagus in colonoscopy patients with and without heartburn.
Douglas K. Rex,Oscar W. Cummings,Michael Shaw,Mark Cumings,Roy K.H Wong,Raj S Vasudeva,Donal Dunne,Emad Y. Rahmani,Debra J. Helper +8 more
TL;DR: Overall, BE was not associated with heartburn, although heartburn was more common in persons with LSBE or circumferential short segments, and SSBE is relatively common in people age > or =40 years with no prior endoscopy, irrespective of heartburn history.
Journal ArticleDOI
Colonic Neoplasia in Asymptomatic Persons With Negative Fecal Occult Blood Tests: Influence of Age, Gender, and Family History
Douglas K. Rex,Glen A. Lehman,Thomas M. Ulbright,Jennefer J. Smith,David Pound,Robert H. Hawes,Debra J. Helper,Maurits J. Wiersema,Carl D. Langefeld,Wei Li +9 more
TL;DR: The prevalence of colonic neoplasia in asymptomatic persons with negative fecal occult blood tests is substantial, particularly in elderly males, and a family history of a single first-degree relative diagnosed at age > or = 60 yr with colorectal cancer is not associated with an increased prevalence of Colonic adenomas.
Journal ArticleDOI
Diastolic collapse of the right ventricle with cardiac tamponade: An echocardiographic study
TL;DR: The value of a newly described echocardiographic sign for the detection of cardiac tamponade was retrospectively evaluated in 91 patients and appears to be a reliable indicator that the pericardial effusion is exerting little effect on overall cardiac function.
Journal ArticleDOI
5-year incidence of adenomas after negative colonoscopy in asymptomatic average-risk persons [see comment]
Douglas K. Rex,Oscar W. Cummings,Debra J. Helper,Thomas V. Nowak,James M. McGill,Gene Z. Chiao,Paul Y. Kwo,Klaus Gottlieb,Steven O. Ikenberry,Frank G. Gress,Glen A. Lehman,Lawrence J. Born +11 more
TL;DR: In average-risk persons, the interval between screening examinations can be safely expanded beyond 5 years, provided the initial examination is a carefully performed complete colonoscopy that is negative for colonic adenomas or cancer.
