Background:
We investigate the effects of sodium valproate, a gamma-aminobutyric acid transaminase inhibitor, on the clinico-physiologic state after ileoanal anastomosis.
Methods:
Twelve patients (five with ulcerative colitis and seven with familial adenomatous polyposis coli) were studied in a placebo-controlled trial.
Results:
Placebo had no effect, but valproate increased the resting anal pressure by 22.4% and the maximum tolerable pouch volume by 20.7%. It also prolonged pouch emptying by 47.3%, with an associated improvement in stool frequency and incontinence. These results suggested that valproate improved both reservoir continence and sphincter continence.
Conclusions:
Only minimal side effects were noted, so the administration of sodium valproate appears to be a safe and useful adjunct for patients with ileoanal anastomosis in the early postoperative period.
