METHODS:Ninety consecutive patients undergoing small bowel capsule endoscopy(SBCE)between January and May 2008 were included in the study. They swallowed the capsule in the standing(Group A= 30),supine(Group B=30)and right supine positions (Group C=30).Baseline patient characteristics, difficulties in capsule ingestion,esophageal transit times(ETT)and Z-line visualization were noted. RESULTS:No significant differences were found between the groups with regard to baseline patient characteristics,ingestion difficulties and complete SB examinations(P>0.05).At least 1 frame of the Z-line was detected in 15.8%,46.7%and 90%of patients in groups A,B and C,respectively(P<0.001).The average number of Z-line images was 0.21±0.53,3.23 ±6.59 and 5.53±7.55 and the mean%of the Z-linedetected was 71.3,25.1 and 8.3,in groups A,B and C, respectively(both P<0.001).ETT times were longer in the supine group followed by the right supine and the standing groups(median of 237 s vs 64 s and 39 s, respectively;P<0.001). CONCLUSION:Z-line visualization in patients undergoing SBCE can be accurately achieved in most cases when the capsule is swallowed in the right supine position.展开更多
