Clinical and anorectal manometric assessments of bowel control was done in 4 patients with total colon aganglionosis and 1 with extensive aganglionosis. All of these 5 patients had undergone Martin's operation. The frequency of bowel movements in patients with total colon aganglionosis decreased 3 times a day 1 year postoperatively and 1 time a day 2 years postoperatively. On the con-trary, the frequency of bowel movements in the patients with extensive aganglionosis was 8 times in a day 1 year postoperatively. With regard to consistency of stools the patients with total colon aganglionosis had loose stool 3 months after Martin's operation, and formed stool 2years after Martin's operation. On the other hand, the patient with extensive aganglioncsis began to have loose stool 6 months after Martin's operation. Anorectal manometric study showed a gradual increase of rectal compliance with the passage of time. Therefore, these results indicate that an achievement of fecal continence after Martin's operation is depend on the increasing of rectal compliance as well as on a re-absorptive capacity of the residual aganglionic colon.
