AIM: To evaluate the completion rate and diagnostic yield of the Pill Cam SB2-ex in comparison to the Pill Cam SB2.METHODS:Two hundred cases using the 8-h Pill Cam SB2 were retrospectively compared to 200 cases using the 12 h Pill Cam SB2-ex at a tertiary academic center.Endoscopically placed capsules were excluded from the study.Demographic information,indications for capsule endoscopy,capsule type,study length,completion of exam,clinically significant findings,timestamp of most distant finding,and significant findings beyond 8 h were recorded.RESULTS:The 8 and 12 h capsule groups were well matched respectively for both age(70.90±14.19vs 71.93±13.80,P=0.46)and gender(45.5%vs48%male,P=0.69).The most common indications for the procedure in both groups were anemia and obscure gastrointestinal bleeding.Pill Cam SB2-ex had a significantly higher completion rate than Pill Cam SB2(88%vs 79.5%,P=0.03).Overall,the diagnostic yield was greater for the 8 h capsule(48.5%for SB2vs 35%for SB2-ex,P=0.01).In 4/70(5.7%)of abnormal SB2-ex exams the clinically significant findingwas noted in the small bowel beyond the 8 h mark.CONCLUSION:In our study,we found the Pill Cam SB2-ex to have a significantly increased completion rate,though without any improvement in diagnostic yield compared to the Pill Cam SB2.

Endoscopically placed capsules were excluded from the study. Demographic information, indications for capsule endoscopy, capsule type, study length, completion of exam, clinically significant findings, timestamp of most distant finding, and significant findings beyond 8 h were recorded. RESULTS: The 8 and 12 h capsule groups were well matched for both age (70.90 ± 14.19 vs. 71.93 ± 13.80, P = 0.46) and gender (45.5% vs 48% male, P = 0.69) common indications for the procedure in both groups were anemia and obscure gastrointestinal bleeding. Pill Cam SB2-ex had a significantly higher completion rate than Pill Cam SB2 (88% vs 79.5%, P = 0.03) the 8 h capsule (48.5% for SB2 vs 35% for SB2-ex, P = 0.01) .In 4/70 (5.7%) of abnormal SB2-ex exams the clinically significant findingwas noted in the small bowel beyond the 8 h mark. CONCLUSION: In our study, we found the Pill Cam SB2-ex to have a significantly increased completion rate, though without any improvement in diagnostic yield compared to the Pill Cam SB2.
