Anesthesia enteroscope application of endoscopic mucosal resection in elderly patients with colorectal polyps

Objective To investigate the clinical value of endoscopic mucosal resection( EMR) treated with colorectal polyps in aged patients under painless colonoscopy. Methods A total of 306 aged patients with colorectal polyps were divided into two groups randomly: painless group( n = 156) who received propofol and fentanyl to anesthesize,routine group( n = 150) who received normal colonoscopy. The blood pressure( containt SBP,DBP),heart rate( HR) and pulse oxygen saturation( Sp O2) before,during and after the operation were recorded,and the reactions during operating,complications,the time of operating colonoscopy and satisfaction rate of the physicians to colonoscopy field of view were observed. Results There was no significant difference in Sp O2 before,during and after the operation between two groups( P 0. 05). During operation,SBP,DBP,HR in painless group were lower than routine group( P 0. 05),but there was no significant difference between two groups before and after the operation. Patients had good tolerance for operation,no apparent adverse reactions during operation were shown in painless group,the vision was exposed fully. The time of operation were( 18. 1 ± 6. 3) min in painless group,( 24. 4 ± 8. 5) min in routine group,and there was statistic significance( P 0. 05). Conclusion EMR under painless colonoscopy can shorten curative time,increase the success rate and improve satisfaction rate of aged patients. EMR under painless colonoscopy is an easy,safe,effective method as a therapy for colorectal polyps.
