Abstract
Ileostomy function was studied in 12 patients with an established ileostomy following proctocolectomy, in 6 of whom minimal amounts (less than 9 cm) and in 6 significant amounts (30–120 cm, mean 60 cm) of terminal ileum had been removed. Patients who had undergone significant ieal resection had daily faecal volumes considerably greater than those with minimal ieal resection (1202 ± 284 ml versus 401 ± 92 ml, P< 0·001), and also greater daily outputs of sodium (146 ± 53 mEq versus 43 ± 12 mEq) and potassium (12·7 ± 9·0 mEq versus 4·0 ± 0·99 mEq). The percentage water content of the ileostomy fluid was greater in patients who had had the ileum resected (93·1 ± 1·8 per cent versus 89·8 ± 2·5 per cent). In addition, the sodiumfpotassium ratio in the urine in patients with a properly acting ileostomy after ileal resection was low. It is Concluded that when recurrent inflammatory bowel disease, partial small bowel obstruction and intraperitoneal sepsis have been excluded there remains a number of patients whose high ileostomy output is due entirely to the amount of ileum resected. The management of patients with a high output ileostomy with codeine phosphate, Lomotil and oral administration of sodium chloride tablets is discussed.
