Baba et al reported factors associated with rebleeding in a patient with occult gastrointestinal bleeding. The authors are from Okayama University in Japan.
Patient selection: occult gastrointestinal bleeding
In the study the source of bleeding was not identified in 47% and rebleeding was confirmed in 17%.
Rebleeding was defined as repeated visible bleeding or progressive anemia requiring repeated endoscopic examinations.
Predictors of rebleeding:
(1) overt episode of bleeding (odds ratio 3.7)
(2) vascular lesion (angiectasia, Dieulafoy lesion, arteriovenous malformation; odds ratio 6.5)
(3) chronic kidney disease (defined as serum creatinine above the upper limit of normal; odds ratio 2.8)
