title: Meckel's diverticulum of the proximal jejunum.
abstract: There are no well-substantiated reports, to our knowledge of a Meckel's diverticulum arising outside the limits of the terminal ileum. We saw a diverticulum located in the proximal jejunum that fulfilled the anatomic and histologic criteria for the diagnosis of a Meckel's diverticulum. This was an incidental finding during the treatment of a sliding esophageal hiatus hernia and caused no apparent difficulty to the patient.
