OBJECTIVE: To clarify the frequency, presentation, associated factors, treatment and outcome of @entity2753 after transphenoidal surgery of @entity977 . METHODS: Retrospectively reviewed the database of 183 @entity1 who underwent transphenoidal surgery of pituitary @entity652 between January 1999 and June 2000 in our department. RESULTS: 38.8% (71/183) had postoperative @entity2753 . Among them, 59.2% (42/71) appeared on the 4th to 7th day postoperatively. 59.2% (42/71) presented with @entity390 , @entity391 , @entity10 , @entity1296 , @entity911 and @entity425 . @entity2753 was related to age, @entity5 size and @entity652 type, but not related to sex and degree of resection. Treatment consisted of salt replacement and mild fluid restriction in 4 @entity1 and salt and fluid replacement in 67 @entity1 . @entity2753 resolved within 16 days in all the @entity1 . CONCLUSIONS: @entity2753 often appeared about 7 days after transsphenoidal surgery of @entity977 , especially in elderly and @entity1 with macroadenomas and huge @entity977 . The principle of treatment was salt and fluid replacement.
