    Radiology, 2006
    Co-Authors: Justin W. Kung, Marc S. Levine, Stephen E. Rubesin, Seth N. Glick, Paras Lakhani, Igor Laufer
    Abstract:

    Purpose: To retrospectively determine the diagnostic yield of Double-Contrast Barium Enema examinations performed for colorectal cancer screening of neoplasms 1 cm or larger or advanced neoplastic lesions of any size in average-risk adults older than 50 years. Materials and Methods: The Institutional Review Board at the affiliated Veterans Affairs Medical Center approved this HIPAA-compliant study protocol and did not require informed consent from patients. Computerized databases revealed 276 Double-Contrast Barium Enema examinations performed for colorectal cancer screening in average-risk adults older than 50 years. Radiographic and pathologic reports were reviewed to determine the number of patients who had polypoid lesions 1 cm or larger, polyps smaller than 1 cm, or advanced neoplastic lesions of any size. Forty-five (16.3%) of the 276 patients underwent follow-up sigmoidoscopy or colonoscopy. Medical, endoscopic, and pathologic records were reviewed and compared with radiographic findings. Results: ...

  • Double-Contrast Barium Enema technique.
    Radiologic Clinics of North America, 2003
    Co-Authors: Stephen E. Rubesin, Dean D.t. Maglinte
    Abstract:

    : During a Double-Contrast Barium Enema the radiologist interacts with the patient, the controls of the fluoroscope, and the image on the television monitor. The radiologist paints an image of the colon; the Barium is the paint, the colon is the canvas. The radiologist manipulates the Barium pool, the air column, and the patient to create images. Although the radiologist may have a plan going into the examination, the game plan is altered by the patient's ability to tolerate and perform the study, the length of the colon, and pathology encountered. If the radiologist understands the goals to be achieved, the studied can be tailored to fit what is happening in the fluoroscopic suite.

  • Ileocecal valve: spectrum of normal findings at Double-Contrast Barium Enema examination.
    Radiology, 2003
    Co-Authors: Lisa C. El-amin, Marc S. Levine, Stephen E. Rubesin, Janak N. Shah, Michael L. Kochman, Igor Laufer
    Abstract:

    PURPOSE: To characterize the spectrum of normal findings of the ileocecal valve at Double-Contrast Barium Enema examination to allow differentiation between a normal valve and one infiltrated by tumor. MATERIALS AND METHODS: A search of radiology and endoscopy files showed 106 patients who underwent Double-Contrast Barium Enema examination and colonoscopy. The radiographic images were reviewed by two authors to determine the morphology of the ileocecal valve and to evaluate whether it appeared normal or abnormal. The radiographic data were then correlated with endoscopic and pathologic findings. RESULTS: The ileocecal valve was visible in 91 (86%) of 106 patients. It was round or ovoid in 71 patients (78%) and triangular in 20 (22%). In the 88 patients with a normal valve at colonoscopy, mean valve height was 1.7 cm, and mean width was 2.8 cm. The valve was smooth in 75 patients (85%) and smoothly lobulated in 13 (15%). The lips of the valve were symmetric in 77 patients (88%) and asymmetric in 11 (12%). ...

  • Diagnosis of colorectal neoplasms at Double-Contrast Barium Enema examination.
    Radiology, 2000
    Co-Authors: Marc S. Levine, Stephen E. Rubesin, Igor Laufer, Hans Herlinger
    Abstract:

    The Double-Contrast Barium Enema examination has been recognized as an option for colorectal cancer screening in Americans with average risk who are greater than 50 years of age. The purpose of this article is to review the principles for diagnosing colorectal neoplasms on Double-Contrast images and the spectrum of findings associated with these lesions. Colonic polyps can be sessile or pedunculated; their appearance depends on whether they are located on the dependent or nondependent wall of the bowel. Villous tumors may be flat, lobulated lesions, also known as “carpet” lesions, that are characterized by a finely nodular or reticular surface pattern, without a discrete mass. Colonic carcinomas may manifest as plaquelike, polypoid, semiannular (“saddle”) or annular lesions. Colonic neoplasms sometimes are more difficult to detect in the region of the ileocecal valve or the distal rectum or in patients with severe diverticulosis. Careful Double-Contrast technique and meticulous scrutiny of the images ther...

  • Double-Contrast Barium Enema Examination Technique
    Radiology, 2000
    Co-Authors: Stephen E. Rubesin, Marc S. Levine, Igor Laufer, Hans Herlinger
    Abstract:

    This review article presents the principles for performing a safe, comfortable, and accurate Double-Contrast Barium Enema examination. The procedure is a flexible examination in which the fluoroscopist interacts with the patient, the controls of the fluoroscope, and the image on the television monitor. During a Double-Contrast examination, images of the colon are created by manipulating the patient, the Barium pool, and the amount of air insufflated into the rectum. Fluoroscopy is essential for guiding the radiologist to obtain spot images with adequate technical factors. The fluoroscopist analyzes the luminal contour, the Barium-coated mucosal surface en face, and the Barium pool to detect abnormalities in the colon. With careful technique, a high-quality examination can be performed in most patients.

  • anisakiasis of the colon radiologic and endoscopic features in six patients
    Radiology, 1992
    Co-Authors: Takayuki Matsumoto, M Iida, Yutaka Kimura, Keiichi Tanaka, T Kitada, M Fujishima
    Abstract:

    The radiologic and endoscopic findings in six patients with anisakiasis of the colon were analyzed. The diagnosis was based on the demonstration of Anisakis larvae at radiography or on elevated serum levels of antibodies to this parasite. All patients reported abdominal symptoms 12-23 hours after the ingestion of raw fish. Double-Contrast Barium Enema examination, performed 2-4 days after the onset of syptoms in all the patients, revealed that the right side of the colon was frequently affected by edema, which was radiographically demonstrated as luminal narrowing and thumbprinting. In addition, the worm was shown at radiography in four patients. Colonoscopy, performed 1-7 days after the onset of symptoms, revealed edematous mucosa, characterized by narrowing and multiple smooth and round protrusions, in all four of the patients studied, but it failed to demonstrate the worm in any patient. The authors believe that the demonstration of these features, together with a history of raw fish ingestion, is esse...

  • Internal hemorrhoids: diagnosis with Double-Contrast Barium Enema examinations
    Radiology, 1990
    Co-Authors: Marc S. Levine, Stephen E. Rubesin, Olle Ekberg
    Abstract:

    The authors retrospectively studied 43 patients suspected of having internal hemorrhoids at Double-Contrast Barium Enema examination. At endoscopy, 24 patients (56%) had internal hemorrhoids, four (9%) had other pathologic lesions in the rectum without evidence of hemorrhoids, and 15 (35%) had no reported abnormalities in the rectum. Internal hemorrhoids were found at endoscopy in 10 of 20 patients (50%) with lobulated folds extending 3 cm or less from the anorectal junction and 10 of 13 patients (77%) with multiple submucosal nodules. However, no patients with these characteristic radiographic findings were found to have other pathologic lesions in the rectum that had been mistaken for hemorrhoids at Barium Enema examination. Conversely, three of four patients with lobulated folds extending more than 3 cm from the anorectal junction and one of six patients with solitary nodules had proctitis or rectal neoplasms. Thus, specific criteria are suggested for the diagnosis of internal hemorrhoids on Double-Contrast Barium Enema examinations. Suspected hemorrhoids that do not fulfill these criteria should be evaluated endoscopically to rule out other more serious pathologic lesions in the rectum.

  • Patient acceptability of CT colonography compared with double contrast Barium Enema: results from a multicentre randomised controlled trial of symptomatic patients
    European Radiology, 2011
    Co-Authors: Christian Wagner, Samuel Smith, Steve Halligan, Alex Ghanouni, Emily Power, Richard J. Lilford, Dion Morton, Edward Dadswell, Wendy Atkin, Jane Wardle
    Abstract:

    Objectives To determine patient acceptability of Barium Enema (BE) or CT colonography (CTC). Methods After ethical approval, 921 consenting patients with symptoms suggestive of colorectal cancer who had been randomly assigned and completed either BE ( N  = 606) or CTC ( N  = 315) received a questionnaire to assess experience of the clinical episode including bowel preparation, procedure and complications. Satisfaction, worry and physical discomfort were assessed using an adapted version of a validated acceptability scale. Non-parametric methods assessed differences between the randomised tests and the effect of patient characteristics. Results Patients undergoing BE were significantly less satisfied (median 61, interquartile range [IQR] 54–67 vs. median 64, IQR 56–69; p  = 0.003) and experienced more physical discomfort (median 40, IQR 29–52 vs. median 35.5, IQR 25–47; p
