Upper gastrointestinal findings detected by capsule endoscopy in obscure gastrointestinal bleeding

Objective: we analyzed our experience with the use of capsule endoscopy in areas that can be explored with gastroscopy to justify obscure bleeding, as well as the outcome after a new recommended gastroscopy in order to determine if a second gastroscopy before the capsule study can provide any benefit in the management of this disease. Methods: we retrospectively studied 82 patients who were explored with capsule endoscopy for obscure gastrointestinal bleeding who had undergone previously only one gastroscopy. Findings in the zones which were accessible by gastroscopy were normal, mild/known and severe/unknown. In the latter cases we recommended a second gastroscopy, and their treatment and outcome were subjected to further study. Results: capsule endoscopy did not find any unknown esophageal findings. In 63% of cases, no gastric or duodenal lesions were shown; in 20%, lesions were mild or had been previously diagnosed, and in 17%, a new gastroscopy was recommended due to the discovery of an unknown condition which could be the cause of the obscure bleeding. This new information brought about a change in treatment for 78% of patients in this group, all of whom improved from their illness. Capsule endoscopy found significant intercurrent alterations in the small intestine in only 14% of cases. Conclusions: the performance of a second gastroscopy, previous to capsule endoscopy, in the study of obscure gastrointestinal bleeding can offer benefits in diagnostic terms and may introduce therapeutic changes. A detailed analysis of the upper tract frames in intestinal capsule endoscopy studies is mandatory since it may provide relevant information with clinical impact on the management of these patients.
