Uchida et al reported a nomogram for predicting the risk of a rebleed for a patient with small bowel bleeding (SBB). The authors are from Nagoya University in Japan.
Patient selection: small bowel bleed
Parameters:
(1) age in years
(2) sex
(3) type of small bowel bleed (SBB)
(4) transfusion
(5) cardiovascular disease
(6) liver cirrhosis
(7) finding on small bowel capsule endoscopy
(8) treatment

Interpretation:
• minimum score: 0
• maximum score: 22.21
value of X =
= 4.852 - (0.2732 * (score))
probability of rebleeding within 2-years =
= 1 / (1 + EXP((-1) * X))
