Bowel cleansing before colonoscopy: Balancing efficacy, safety, cost and patient tolerance. - World journal of gastrointestinal endoscopy
Effective colorectal cancer screening relies on reliable colonoscopy findings which are themselves dependent on adequate bowel cleansing. Research has consistently demonstrated that inadequate bowel preparation adversely affects the adenoma detection rate and leads gastroenterologists to recommend earlier follow up than is consistent with published guidelines. Poor preparation affects as many as 30% of colonoscopies and contributes to an increased cost of colonoscopies. Patient tolerability is strongly affected by the preparation chosen and manner in which it is administered. Poor tolerability is, in turn, associated with lower quality bowel preparations. Recently, several new developments in both agents being used for bowel preparation and in the timing of administration have brought endoscopists closer to achieving the goal of effective, reliable, safe, and tolerable regimens. Historically, large volume preparations given in a single dose were administered to patients in order to achieve adequate bowel cleansing. These were poorly tolerated, and the unpleasant taste of and significant side effects produced by these large volume regimens contributed significantly to patients' inability to reliably complete the preparation and to a reluctance to repeat the procedure. Smaller volumes, including preparations that are administered as tablets to be consumed with water, given as split doses have significantly improved both the patient experience and efficacy, and an appreciation of the importance of the preparation to colonoscopy interval have produced additional cleansing.
MiraLAX is not as effective as GoLytely in bowel cleansing before screening colonoscopies. - Clinical gastroenterology and hepatology : the official clinical practice journal of the American Gastroenterological Association
Successful colonoscopies require good bowel preparations-poor bowel preparations can increase medical costs, rates of missed lesions, and procedure duration. The combination of polyethylene glycol (PEG) 3350 without electrolytes (MiraLAX; Schering-Plough Healthcare Products, Inc, Kenilworth, NJ) and 64 oz of Gatorade (PepsiCo, Inc, Purchase, NY) has gained popularity as a bowel preparation regimen. However, the efficacy and tolerability of this approach has not been compared with standard bowel preparations in clinical trials. We compared split-dose (PEG) 3350 with electrolytes (GoLytely; Braintree Laboratories, Inc, Braintree, MA) with split-dose MiraLAX alone and in combination with pretreatment medications (bisacodyl or lubiprostone) to determine the efficacy and patient tolerability of MiraLAX as an agent for bowel preparation.We performed a prospective, randomized, blinded, controlled trial at a tertiary care center. Patients (n=403) were randomly assigned to groups given GoLytely, MiraLAX, MiraLAX with bisacodyl (10 mg), or MiraLAX with lubiprostone (24 μg). MiraLAX was combined with 64 oz of Gatorade. All patients were surveyed regarding preparation satisfaction and tolerability. The Ottawa bowel preparation scale was used to grade colon cleanliness.GoLytely was more effective at bowel cleansing (average Ottawa score, 5.1) than MiraLAX alone (average Ottawa score, 6.9) or in combination with lubiprostone (average Ottawa score, 6.8), or bisacodyl (average Ottawa score, 6.3) (P<.001). MiraLAX was associated with a trend toward longer procedure duration (P=.096). Groups given MiraLAX rated the overall experience as more satisfactory than those given GoLytely (P<.001). There were no differences between polyp detection rates (P=.346) or adverse events (P=.823).Split-dose MiraLAX in 64 oz of Gatorade is not as effective as 4 L split-dose GoLytely in bowel cleansing for screening colonoscopies.Copyright © 2011 AGA Institute.
