Children who underwent enterocystoplasty at the
present institution prior to August 2007 were
reviewed. Patients with non-ileal augment, insuffi-
cient follow-up or hematologic disorders were
excluded. Patients with low or low-normal B12 levels
were included. Treatment consisted of daily oral
therapy of 250 mcg or monthly parenteral therapy of

of 898 patients who underwent enterocystoplasty
was searched and patients with at least one postoperative
B12 level were highlighted. The indication
