Though the mechanisms of continence after proctocolectomy and @entity4628 -anal @entity254 have been studied, functions of the small intestine have received little attention. However, frequent stools and urgency plague some @entity1 who are otherwise quite continent. Motility of the jejunum and ileum was assessed in eight @entity1 with @entity31 who were studied 4 to 24 months after proctocolectomy and @entity4628 -anal @entity254 ; these findings were compared to those in six healthy volunteers. Continuous manometric recordings from the small bowel were obtained in both groups for 16 to 23 hours of @entity4053 ; postprandial recordings were made for 6 hours following a mixed meal (800 kcal, 20% protein, 40% fat, 40% @entity1735 ) in the ileoanal @entity1 . The duration, velocity of propagation, and periodicity of the migrating motor complex did not differ between the groups (P greater than 0.05). Discrete bursts of clustered contractions were recorded from all of the controls and in five of eight @entity1 . Likewise, we recorded from all controls and five of eight @entity1 large amplitude, prolonged waves of pressure which propagated distally. However, in controls these large amplitude waves were confined to the terminal ileum, but in @entity1 these were detected in the jejunoileum, up to 125 cm proximal to the @entity4628 . We conclude that jejunoileal motility is not greatly altered by proctocolectomy with @entity4628 -anal @entity254 . However, the appearance of the large amplitude, rapidly propagating waves in the proximal jejunoileum after operation may be a response to increased storage within and distention of the distal bowel.
