Detailed Description
Colorectal cancer is a leading cause of death from cancer. Because colonic cancer begins as a small adenoma that , evolves into carcinoma over a decade or more pre-emptive colonoscopic polypectomy can prevent this malignancy. For a good colonoscopic examination ideally the colon should be cleansed of all fecal material because poor bowel preparation before colonoscopy often leads to inability to reach the cecum or poor visualization of the mucosa . Thus , pathology may be missed, repeat examinations may be scheduled at earlier intervals than planned and the procedure is more difficult and time consuming. In addition , poor bowel preparation can increase the risk of significant complications. Perforations resulting from maneuvers has greater consequences in the setting of inadequate bowel preparation.
In the past two decades , various bowel preparation methods have been proposed including castor oil, anthraquinones, phenolphtalein and magnesium citrate, in combination with low residue diet4-7. Along these agents , cleansing enemas formed the traditional bowel preparation. Oral sodium phosphate (Fleet Phospo-soda, C.B Fleet Co, Inc., Lynchburg, Va.)(NaP) a preparation containing dibasic and monobasic sodium phosphate was proven to be cost effective and has since been used worldwide8,9. NaP osmotically draws plasma water into the bowel lumen to promote bowel cleansing. NaP must be accompanied by significant oral fluid to prevent dehydration. Patients with compromised renal function, dehydration, hypercalcemia or hypertension with the use of angiotensin converting enzyme inhibitors have experienced phosphate nephropathy after use of oral NaP solutions.
Senna laxatives containing sennosides activated by colonic bacteria have a direct effect on intestinal mucosa increasing the rate of colonic motility , enhancing colonic transit, and inhibiting water and electrolyte secretion10. Sennosides may result in hypokalemia and atonic colon.
The aim of our study is to assess the bowel cleansing effects of two different agents and to compare their safety of application, ease of usage and effects on serum electrolytes.
