Background
Increased familiarity with capsule endoscopy (CE) has been associated with a growing demand for urgent inpatient procedures. Limited data exists comparing the effect of admission status on colon capsule (CCE) and pan-intestinal capsule (PIC) performance. We aimed to compare the quality of inpatient versus outpatient CCE and PIC studies.
Methods
A retrospective nested case-control study. Patients were identified from a CE database. PillCam Colon 2 Capsules with standard bowel preparation and booster regimen were used in all studies. Basic demographics and key outcome measures were documented from procedure reports and hospital patient records, and compared between groups.
Results
105 subjects were included, 35 cases and 70 controls. Cases were older, were more frequently referred with active bleeding and had more PICs. The diagnostic yield was high at 77% and was similar in both groups. Completion rates were significantly better for outpatients, 43% (n = 15) v’s 71% (n = 50), OR 3, NN3. Neither gender nor age affected completion rates. Completion rates and preparation quality were similar for CCE and PIC inpatient procedures.
Conclusion
Inpatient CCE and PIC have a clinical role. There is an increased risk of incomplete transit in inpatients, and strategies to mitigate against this are needed.
