Colonoscopy Preparation: Comparing Sennoside A+B and PM/Ca
Colonoscopy is a test used to examine the inside of the bowel. Proper bowel preparation is crucial because it helps doctors get a clear view during the procedure.
What is Sennoside A+B? Sennoside A+B is a type of laxative made from the senna plant. It works by stimulating the bowel to move and reducing the absorption of water, making it easier to pass stools. Research has shown that high doses of sennoside A+B can be effective for bowel preparation.
Sennoside A+B vs. PEG:
Some studies have found that sennoside A+B is more effective than PEG, another laxative, but can cause more abdominal pain. Other studies have found no significant difference in effectiveness between the two.
What is Picosulfate/Magnesium Oxide/Citric Acid (PM/Ca)? PM/Ca is a combination of sodium picosulfate, magnesium oxide, and citric acid. Sodium picosulfate stimulates bowel movements, while magnesium oxide and citric acid help increase water in the bowel, making it easier to pass stools.
PM/Ca vs. PEG:
Research has shown that PM/Ca is as effective as PEG for bowel preparation. Patients using PM/Ca generally tolerate the preparation process better than those using PEG.
Conclusion:
While PEG is the preferred option according to guidelines, its high cost can make it less accessible in some places. In this study, we aim to compare the effectiveness and patient tolerance of Sennoside A+B and PM/Ca since no direct comparison between these two preparations has been made before.
