Introduction
Capsule endoscopy is the first-line examination for digestive bleeding with likely origin in the small bowel, in hemodynamically stable patients. In the 2022 update, ESGE guidelines recommend that, in the context of overt bleeding, capsule enteroscopy should be performed as soon as possible, ideally within the first 48 hours. In the previous guidelines, published in 2015, the recommended window was 14 days.
Aims & Methods
This study aimed to evaluate the improvement in yield offered by the new recommendations regarding the timing of urgent capsule enteroscopy. Patients with suspected overt middle gastrointestinal bleeding between January 2005 and November 2022 were retrospectively analyzed. Diagnostic and therapeutic yield, rebleeding rate, and mortality were compared when capsule enteroscopy was performed within the first 48 hours, within the first 14 days, or between the 3rd and 14th day after admission.
Results
A total of 138 patients were included (58.7% men, median age 66 years), 87 of whom (63.0%) underwent capsule enteroscopy within the first 48 hours after hospital admission. The median follow-up was 55 months (5-180). The diagnostic yield (presence of blood or lesions with bleeding potential) was slightly higher when capsule enteroscopy was performed within the first 48 hours (81.6% versus 76.5%, p=0.349). On the other hand, capsule enteroscopy within the first 48 hours was significantly associated with higher therapeutic yield (endoscopic, radiologic, or surgical treatment) - 54.0% versus 39.2%, p=0.02. The rebleeding rate was significantly lower in patients undergoing enteroscopy within 48 hours after admission (19.5% versus 29.4%, p=0.04). On the other hand, overall mortality at 36 months did not differ between strategies (21.8% and 25.5%, p=0.401).
Conclusion
Performing capsule endoscopy within the first 48 hours, as recommended by recently published guidelines, is associated with favourable short- and long-term clinical outcomes.
