OBJECTIVE: Failure to diagnose @entity5 leads to errors in @entity1 treatment and prognosis. The existence of @entity5 requires strict @entity1 follow-up to ensure early identification of the second @entity5 . The present study evaluates the results obtained in the application of a structured procedure for the diagnosis and follow-up of multiple @entity14 . MATERIALS AND METHODS: A structured procedure was used to follow for 5 years a group of 12 @entity1 with multiple @entity14 (7 synchronous and 5 metachronous) of a series of 450 @entity14 . RESULTS: Six @entity5 were diagnosed preoperatively and one intraoperative. Of the 5 metachronous neoplasms, 4 strictly adhered to the follow-up protocol, as a result of which the second @entity5 was detected at an early stage. The remaining case involved no follow-up, and the second @entity5 was diagnosed in an advanced stage as a result of @entity432 . The left colon was predominantly involved; @entity1127 were detected in 9 cases, while two @entity1 had 3 @entity5 detected by histopathological study. COMMENTS: We emphasize the need for a full evaluation of the colon in all @entity1 with @entity14 . In the case of incomplete preoperative evaluation, intraoperative colonoscopy is to be considered; if this is not feasible it should be performed one month after surgery. A structured follow-up procedure permits the early detection of these @entity5 , there by improving @entity1 prognosis.
