Persistence of proctitis in 2 cases of clindamycin-associated colitis.

Two cases of persisting proctitis after an episode of clindamycin-associated colitis are reported. Both patients had fulminant colitis and required emergency operation. Severe proctitis persisted in the rectal stumps until their removal 8 months after the initial diagnosis of colitis was made. Persisting proctitis has not previously been described in clindamycin-associated colitis.
