Real Food for Colonoscopy Preparation

Colonoscopies save lives. It is recommended that adults start having them at age 50 to detect pre malignant colon abnormalities and early colon cancer. For the physician performing the test, the colon must be clean of digested food and stool to observe the lining cells of the colon. The presence of fecal material blocks the view of the colonic mucosa. Those of us who have taken screening colonoscopies are well aware that the preparation for the test is far worse than the actual procedure (which you are usually sedated for in some manner.) Most colonoscopy preps involve starting a laxative the afternoon before the procedure and staying on clear liquids the whole day until the procedure is complete. Some preps ask you to drink large volumes of soapy flavored liquids. Others use smaller quantities of chemicals but the end result is frequent loose and watery stools until the stool looks the same on the way out as it does on the way in. At best the preparation is a necessary but unpleasant experience.

Corey Siegel, MD MS and Dough Knuth, RD along with Joshua Korzenik, MD, of Harvard Medical School have produced real food laced with PEG-3350 as a colonoscopy prep. They are so confident of this preps efficacy that they formed a company to produce it called Colonary Concepts Inc. Foods such as pasta, pretzels with dipping sauce, smoothies and nonalcoholic Pina coladas have been mixed with laxatives to produce a colonoscopy prep. They reported on their study results at Digestive Disease Week and in MedPage Today. According to the endocscopists who performed the studies on these patients, the colon was good to excellent in preparation for viewing. The patients had no problems with the prep and said they would gladly choose the real food prep again for future colonoscopies. Based on the favorable review of this prep a larger Phase II study is now in progress. This is a step forward for a necessary but uncomfortable screening procedure.
