Background: Attention has focused on whether normalization, regression, and development of dysplasia and cancer in specialized intestinal metaplasia (SIM) differ among long-segment Barrett's esophagus (LSBE), short-segment BE (SSBE), and esophagogastric junction SIM (EGJSIM). We prospectively followed a cohort of SIM patients receiving long-term antisecretory medications to determine: (a) histologic normalization (no evidence of SIM on biopsy), (b) change in SIM length, (c) incidence of dysplasia and cancer, and (d) factors associated with normalization.
Methods: One hundred forty-eight patients with SIM were identified in our original cohort.
Ectopic gastric mucosa has been described at various locations of the body, including all levels of the gastrointestinal tract. However, this finding is rare in the rectum and anus, with 38 reported cases. In only six cases, including the present one, has the heterotopic tissue been located within 2 cm of the dentate line.

Background & Aims: Diminutive adenomas (1-9 mm in diameter) are frequently found during colon cancer screening with flexible sigmoidoscopy (FS). This trial assessed the predictive value of these diminutive adenomas for advanced adenomas in the proximal colon.
Methods: In a multicenter, prospective cohort trial, we matched 200 patients with normal FS and 200 patients with diminutive adenomas on FS for age and gender.
