OBJECTIVE: To determine whether the features of @entity652 identified in a first endoscopic examination may predict the presence of @entity1127 with advanced pathological features that may have gone unnoticed and whether early colonoscopy may benefit these @entity1 . MATERIAL AND METHODS: We examined 133 @entity1 with diagnosis of @entity1586 who had undergone complete colonoscopy and endoscopic polypectomy. All of them underwent colonoscopic follow-up at 3 years. Seventy nine @entity1 underwent colonoscopic follow-up both at 6 months and at 3 years, while 54 @entity1 underwent just colonoscopic follow-up at 3 years and 47 just at 6 months. RESULTS: Fifteen per cent of the @entity1 analyzed developed @entity1127 with pathological features after 6 months. The size and histological analysis of the @entity1127 detected in the initial colonoscopic examination did not affect these results (p < 0.05). The number of @entity1127 was statistically significant: @entity1 with 3 or more @entity1127 in the initial colonoscopic examination presented more @entity1127 with pathological features after six months (25.8 versus 5.8%, p = 0002). This follow-up examination at 3 years did not reveal a higher occurrence of @entity1127 with pathological features in any of the two groups of @entity1 , namely, those who had undergone early colonoscopy and those who had not. CONCLUSIONS: @entity1 with @entity1127 have greater probability of developing @entity1127 with some pathological features which may have gone unnoticed. Since early examination has not shown to provide a benefit for these @entity1 , the first follow-up colonoscopy should be performed at 3 years, particularly if the initial colonoscopy is negative.

Validity of early colonoscopy for the treatment of XXXX missed by initial endoscopic examination.
