In our experience, these are well tolerated by patients with a history of bariatric surgery and provide adequate colon cleansing before colonoscopy.  \n■ RATIONALE  \nAdequate bowel preparation by the ingestion of a cleansing agent is extremely important before colonoscopy: the quality of colon preparation affects the diagnostic accuracy and safety of the procedure, as inadequate bowel preparation has been associated with failure to detect polyps and with a higher rate of adverse events during the procedure.1–3  \nThe most commonly used bowel preparations can be divided into high-volume (which require drinking at least 4 L of a cathartic solution) and low-volume (which require drinking about 2 L) .4 Polyethylene glycol electrolyte solutions are among the most commonly used and are available in both high-volume (eg, Golytely, Nulytely) and low-volume (eg, Moviprep, Miralax) forms.  \nOther low-volume preparations include sodium picosulfate (Prepopik), magnesium citrate, and sodium phosphate tablets. However, these should be avoided in patients with renal insufficiency.4  \nPrices for bowel preparations vary. For example, the average reported wholesale price of  \nGolytely is $24.56, Moviprep $81.17, and Miralax $10.08.4 However, the final cost depends on the patient’s insurance coverage. Generic formulations are available for some preparations.  \nAfter bariatric surgery,  \npatients have a smaller stomach  \nAfter bariatric surgery, patients have significantly reduced stomach volume, due either to resection of a part of the stomach (such as in partial gastrectomy) or to diversion of the gastrointestinal (GI) tract to bypass most of the stomach (such as in Roux-en-Y gastric bypass) . This causes early satiety with smaller amounts of food and leads to weight loss. However, this restriction in stomach volume also makes it more difficult for the patient to tolerate the intake of large volumes of fluids for bowel cleansing before colonoscopy.  \nBariatric surgery patients may require colonoscopy for indications such as colorectal cancer screening, chronic diarrhea, or GI bleeding, all of which are commonly encountered during routine clinical practice.  \nGuidelines are available  \nCurrently, there are no published data available to support the use of one preparation over another in patients with a history of bariatric surgery. However, for patients who have had bariatric surgery, guidelines from the US Multi-Society Task Force on Colorectal Cancer—endorsed by the three major American gastroenterology societies, ie, the American Gastroenterological Association, the American College of Gastroenterology, and the American Society for Gastrointestinal Endoscopy—recommend either a low-volume  \ndoi:10.3949/ccjm.84a.15179  \nQ: Which bowel preparation should be used for colonoscopy in patients who have had bariatric surgery?  \nGURSIMRAN KOCHHAR, MD  \nDepartment of Gastroenterology and Hepatology, Digestive Disease  \nand Surgery Institute, Cleveland Clinic  \nBO SHEN, MD  \nSection Head and The Ed and Joey Story Endowed Chair, Department of Gastroenterology and Hepatology, Digestive Disease and Surgery Institute, Cleveland Clinic; Professor,  \nCleveland Clinic Lerner College of Medicine of Case Western Reserve University, Cleveland, OH  \nA:  \nCLINIC JOURNAL OF MEDICINE  \nCLEVELAND  \n2017  \nVOLUME 84 • NUMBER 5 MAY  \nARORA AND COLLEAGUES  \nsolution or, if a high-volume solution is used, extending the duration o","cbCaip0UmKxLl0qi","https://ap.wps.com/l/cbCaip0UmKxLl0qi","pdf",146369,"English","# Rationale for bowel preparation quality\n## Types of bowel preparations and key precautions\n## Bariatric surgery considerations\n## Guideline-based recommendations and practical regimen\n## References","[{\"question\":\"Why does bowel preparation quality matter for colonoscopy?\",\"answer\":\"Adequate bowel preparation affects diagnostic accuracy and safety; inadequate cleansing is linked to missed polyps and higher adverse-event rates during the procedure.\"},{\"question\":\"What bowel preparation is commonly used after bariatric surgery?\",\"answer\":\"Low-volume 2-L polyethylene glycol electrolyte preparations in split-dose regimens are routinely used and have been well tolerated in patients with prior bariatric surgery, providing adequate cleansing.\"},{\"question\":\"What do guidelines recommend regarding preparation choice and regimen?\",\"answer\":\"Guidelines recommend either a low-volume solution or, if a high-volume solution is used, extending the duration over which the preparation is consumed, along with sugar-free drinks to avoid dumping syndrome from high sugar intake.\"}]","1-MINUTE CONSULT - BRIEF ANSWERS TO SPECIFIC CLINICAL QUESTIONS - Bowel Preparation for Colonoscopy After Bariatric Surgery | PDF",1790536668]
