Institutional review board statement: The digital file of the PillCam™ SB3 system contains a series of images for each endoscopic record, which were read and reported in a standard format by gastroenterologists; from these reports, data for this research were extracted and an anonymized database was created. Therefore, this research was classified as low risk according to the local ethical regulation in force (Fundación Universitaria Juan N. Corpas Research Committee).

Abstract
BACKGROUND

Video-capsule endoscopy (VCE) is an efficient tool that has proven to be highly useful in approaching several gastrointestinal diseases. VCE was implemented in Colombia in 2003, however current characterization of patients undergoing VCE in Colombia is limited, and mainly comes from two investigations conducted before the SARS-CoV-2 pandemic period.

AIM

To describe the characteristics of patients undergoing VCEs and establish the main indications, findings, technical limitations, and other outstanding features.

METHODS

A descriptive study was carried out using data from reports of VCE (PillCam SB3 system) use in a Gastroenterology Unit in Bogotá, Colombia between September 2019 and January 2023. Demographic and clinical variables such as indication for the VCE, gastric and small bowel transit times (GTT, SBTT), endoscopic preparation quality, and limitations were described [n (%), median (IQR)].

RESULTS

A total of 133 VCE reports were analyzed. Most were in men with a median age of 70 years. The majority had good preparation (96.2%), and there were technical limitations in 15.8% of cases. The main indications were unexplained anemia (91%) or occult bleeding (23.3%). The median GTT and SBTT were 14 and 30 minutes, respectively. The frequencies of bleeding stigma (3.79%) and active bleeding (9.09%) were low, and the most frequent abnormal findings were red spots (28.3%), erosions (17.6%), and vascular ectasias (12.5%).

CONCLUSION

VCE showed high-level safety. The main indication was unexplained anemia. Active bleeding was the most frequent finding. Combined with artificial intelligence, VCE can improve diagnostic precision and targeted therapeutic interventions.

Core Tip: Video-capsule endoscopy (VCE) has proven to be a highly useful and efficient diagnostic tool, not only for obscure and occult bleeding, but also for small bowel diseases. VCE was implemented in Colombia in 2003. However, the current characterization of patients undergoing VCE in Colombia is limited. This research could be useful in promoting the training and use of VCEs as a diagnostic tool, and potentially, as an intervention coadjutant in developing countries.
