Improvement of oral colonic lavage with supplemental simethicone

We have noted that colons of patients prepared for colonoscopy with Golytely, a nonabsorbable electrolyte lavage solution, frequently contain foam which may obscure small mucosal lesions. Therefore, a randomized, blinded controlled trial was performed to determine the prevalence of Golytely-induced foam and the effect of supplemental simethicone in decreasing the prevalence of foam. Foam was present in 32% of colons prepared with Golytely alone but in none of the colons prepared with Golytely supplemented with simethicone. In addition, only 5% of colons prepared with supplemental simethicone had residual stool noted at the time of colonoscopy, a significant improvement over the 39% prevalence of residual stool in colons prepared with Golytely alone. Addition of simethicone to Golytely lavage decreases the prevalence of colonic foam and residual stool.     

聚乙二醇电解质散剂联合低剂量硫酸镁与西甲硅油在结肠镜检查前肠道准备中的应用

Simethicone use during gastrointestinal endoscopy: Position statement of the Gastroenterological Society of Australia

Concern has been raised regarding the use of simethicone, a de‐foaming agent, during endoscopic procedures. Following reports of simethicone residue in endoscope channels despite high level disinfection, an endoscope manufacturer recommended that it not be used due to concerns of biofilm formation and a possible increased risk of microorganism transmission. However, a detailed mucosal assessment is essential in performing high‐standard endoscopic procedures. This is impaired by bubbles within the gastrointestinal lumen. The Gastroenterological Society of Australia's Infection Control in Endoscopy Guidelines (ICEG) Committee conducted a literature search utilizing the MEDLINE database. Further references were sourced from published paper bibliographies. Following a review of the available evidence, and drawing on extensive clinical experience, the multidisciplinary ICEG committee considered the risks and benefits of simethicone use in formulating four recommendations. Published reports have documented residual liquid or crystalline simethicone in endoscope channels after high level disinfection. There are no data confirming that simethicone can be cleared from channels by brushing. Multiple series report benefits of simethicone use during gastroscopy and colonoscopy in improving mucosal assessment, adenoma detection rate, and reducing procedure time. There are no published reports of adverse events related specifically to the use of simethicone, delivered either orally or via any endoscope channel. An assessment of the risks and benefits supports the continued use of simethicone during endoscopic procedures. Strict adherence to instrument reprocessing protocols is essential.     

西甲硅油在胶囊内镜检查中的应用研究

目的：观察西甲硅油在胶囊内镜检查前肠道准备中的清洁和祛泡效果。方法将行胶囊内镜检查的278例患者随机分成研究组和对照组,均使用聚乙二醇电解质散2袋口服进行肠道准备,研究组于检查前1 h服用西甲硅油乳剂30 mL。观察两组患者肠道准备清洁度、肠道气泡量、不良反应发生情况、胶囊内镜小肠通过时间、全小肠检查成功率等指标。结果研究组肠道气泡量明显少于对照组（P＜0．01）,肠道准备过程中的不良反应发生率明显低于对照组（P＜0．01）。两组患者肠道准备清洁度、胶囊内镜检查中的不良反应发生率、胶囊内镜小肠通过时间及全小肠检查成功率比较差异无统计学意义（P＞0．05）。结论西甲硅油能够有效地去除胶囊内镜检查前肠道准备过程中产生的气泡,提高胶囊内镜检查时肠道视野清晰度,且能减少患者肠道准备过程中不良反应的发生。
