Background: Question prompt lists (QPLs) are structured sets of disease-specific questions intended for patient use, enhancing the patient-physician communication by encouraging patients to ask relevant questions during a consultation. Recently, a preliminary 78 question gastroesophageal reflux disease (GERD) specific QPL was created by 12 esophageal experts through a modified Delphi (RAND/University of California, Los Angeles) technique. Patients' perspectives and opinions on each question, however, had not been accounted for in the preliminary expert' version.

Primary care physicians and physician extenders have been encouraged to perform sigmoidoscopy to improve compliance with screening and address the potential shortage of colonoscopists. A survey of primary care teaching programs reveals that sigmoidoscopy training is inconsistent and lacks minimum standards of competency. It would be helpful to know how many primary caregivers offer sigmoidoscopy in their practice and if they are deterred by insufficient resources and falling reimbursement.

Background & Aims: Graded pneumatic dilation (PD) is a widely accepted treatment for achalasia. We investigated the potential predictors of outcome in a large group of patients with achalasia and tested the hypothesis that graded PD may not be appropriate for all patients.

Methods: Patients undergoing PD from 1992 to 2002 were evaluated retrospectively.

Pseudoachalasia is an esophageal motor disorder usually associated with malignancy that has clinical, radiographic, and manometric findings that are often indistinguishable from primary achalasia. There are few reports examining the histologic features of the associated neoplasms and their relationship with the esophageal myenteric plexus. We studied the clinical and pathologic features of 13 cases of pseudoachalasia seen at our institution between 1979 and 1999.
