More than 10 years' follow-up to total colonic aganglionosis--severe iron deficiency anemia and growth retardation.
Seven cases of total colonic aganglionosis were reviewed with a follow-up period of 10 to 26 years, focusing on the relationship between the length of aganglionic ileum and postoperative metabolic disorders. Pulled-through ileum ranged from 0 to 65 cm from the ileocecal valve, and suprapelvic side-to-side anastomosis was performed between the pulled-through ileum and 17 to 40 cm of aganglionic colon (left side and transverse colon, four; right side colon, one; no colonic patch, two). Hemoglobin level in three out of four patients with ileal involvement of more than 25 cm was below 11 g/dL (10.9, 7.7, 6.6 g/dL, respectively). Serum iron level was less than 30 micrograms/dL (27, 21, 20, 18 micrograms/dL, respectively) in four out of five patients with ileal involvement of more than 10 cm. Serum vitamin B12 level was below 100 (100, 46 pg/dL, respectively) in two patients whose pulled-through ileum was 45 cm and 65 cm, respectively from the ileocecal valve. One patient needs periodical parenteral iron therapy and one was treated as megaloblastic anemia. In the patients with ileal involvement of more than 25 cm, both weight and height for age are very low at less than the fifth percentile, except for one patient whose side patch was at the right colon. One patient still needs parenteral nutritional support. Severe iron deficiency anemia, low level of B12, and growth retardation are apparent in the patients with total colonic aganglionosis with ileal involvement. Colonic side-to-side anastomosis does not substitute for the loss of terminal ileum.
