Understanding of an operation and its risks has been shown to give patients more realistic expectations, increase cooperation and result in higher satisfaction. Traditionally, informed consent for surgical procedures involve a discussion between the surgeon and the patient, but many patients easily forget the details of these talks. The investigators wish to investigate if providing a written pamphlet along with the standard oral discussion improves patients' ability to remember the details of the operation, improving the quality of the informed consent process.

In addition, we will test whether a group consultation format provides a model for large-volume, low-variation, low-urgency surgery without reducing ability to recall risks of surgery or overall satisfaction.
