This video case shows how challenging it can be to choose the correct insertion route (anterograde vs retrograde) before an enteroscopy based on video-capsule time index landmarks.
Indeed, these time indexes are not always reliable for identifying the precise localization of a lesion, as shown in this video case.
In some cases, other imaging techniques help us choose the correct approach, or the alternative route will be necessary to reach a lesion.
It is important for us to show how to deal with and overcome these issues in daily practice. Careful video-capsule overview and reporting as well as consideration of all available clinical information (including other imaging) are crucial.
This also highlights the importance of caution when using the motorized spiral enteroscope, a safe and effective device-assisted enteroscopy that, however, requires expertise and optimal patient selection.
Taking care of patients requiring small-bowel exploration goes beyond reading the video-capsule and performing enteroscopy. A patient-centered approach should be adopted. This includes reviewing all available clinical information, choosing the optimal device and route, and adapting management according to the findings.
A, Actively bleeding obstructive lesion visualized through the video-capsule endoscopy in the ileum. B, The lesion’s time-index location is calculated as the ratio of the transit time from the pylorus to the lesion and the transit time from the pylorus to the cecum, suggesting an anterograde approach.
