There is limited evidence to guide the ideal bowel regimen in PD patients. Reasons to consider PEG therapy include the evidence promoting PEG in the general population with constipation, the positive outcomes found in a small population of PD patients (Mimidis 2005), as well as positive feedback from other provinces who currently recommend PEG in PD patients. The investigators postulate the PEG protocol would be as effective and safe as the Current Bowel Protocol, and thus will evaluate PEG in the PD population, the investigators will conduct a prospective, interventional, randomized, open label, pilot study.
