Water instillation is now commonly used for a variety of purposes during colonoscopy. Water filling during colonoscope insertion has been shown to decrease pain, reduce sedative requirements, facilitate cecal intubation in redundant colons, as well as prevent barotrauma and facilitate sigmoid passage in patients with severe diverticular disease. A previous blinded trial showed that water filling during insertion resulted in excess mucus production in the rectosigmoid during withdrawal, but mucus production did not occur when saline solution was used rather than water.<\/p>\n\n\n\n
In a 4-arm randomized trial of 296 patients, rectosigmoid mucus was compared when insertion was performed with water exchange, 25% saline solution, 50% saline solution, or carbon dioxide only. Left-sided colon mucus scores were 1.4, 0.7, 0.5, and 0.2, respectively. Differences between all groups were statistically significant except between the two saline groups. The adenoma detection rate was numerically highest with 50% saline solution (53.9%) and lowest with water exchange (41.3%), but the differences were not significant.<\/p>\n","protected":false},"excerpt":{"rendered":"
