The purpose of this study is to evaluate prospectively the usefulness of IC-CO2(intraoperative colonoscopy (IC) using carbon dioxide (CO2)) in our colon and rectal surgical practice, coincident with laparoscopic surgery, and assess whether it provides useful information that influences the type of surgical therapy intended. We also wish to further define the safety and extent of bowel distension when using IC-CO2. Furthermore, we wish to evaluate the therapy and technique of using this combined approach to the treatment of colorectal polyps and other localized, benign lesions of the large intestine. In this study, the colonoscope is used both as a diagnostic and therapeutic tool, and is often used in order to avoid a major bowel resection, yet effectively treat localized lesions of the large intestine.
