Abstract:
Primary adenocarcinoma of the small intestine comprises one of the rarest gastrointestinal malignancies. Further, the terminal ileum is very seldom implicated. This entity occurs sporadically and evades traditional colonoscopic evaluation in which the terminal ileum is not visualized. Herein, a case of interval development of primary terminal ileal adenocarcinoma over a 2-year period is reported as followed by direct endoscopic and colonoscopic visualization. This case demonstrates cecal involvement not found on initial evaluation without the provision of terminal ileum intubation. Relevant guidelines regarding the evaluation of the terminal ileum in routine colonoscopy are reviewed.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
