Patients and methods
Consecutive patients referred to two hospitals for CE over a period of 18 months were studied. In actual clinical practice, CE differs between the two hospitals with respect to bowel preparation. The study was nonrandomized: patients who had a bowel preparation (Group A) were recruited from the Department of Internal Medicine of the county hospital of St. Gallen, Switzerland; patients without bowel preparation (Group B) were recruited from the Department of Gastroenterology and Hepatology,
Results
A total of 65 consecutive patients underwent CE between March 2002 and September 2003. Four were excluded; 3 because of insufficient data from technical problems (2 data CDs not readable, 1 depleted battery). The third patient did not fast overnight, and massive amounts of residual food made assessment of the small-bowel impossible. The study, therefore, included 61 patients (34 men, 27 women; mean age 56 years, range 17-88 years). Without randomization, 33 patients received the bowel
Discussion
CE has been shown to be the most effective noninvasive method for evaluation of the small bowel, with a significantly higher diagnostic yield compared with push enteroscopy and conventional techniques.4, 5 It is safe, painless, well-tolerated, and has opened a new perspective in the diagnosis of recurrent GI bleeding of obscure origin, Crohn's disease, small-bowel tumors, and polyps.3
Despite its obvious advantages, CE has some limitations. Image quality is not as good as that of flexible
