预处理在内镜下切除结肠巨大息肉中的应用

目的研究金属钛夹钳夹术及去甲肾上腺素黏膜下注射对结肠巨大息肉进行预处理,并探讨预处理对内镜下切除结肠巨大息肉的价值。方法选取行肠镜检查中发现结肠巨大息肉的86例患者,将其按随机数字表法分为预处理组(43例)及对照组(43例)。记录2组肠镜下切除息肉后,出现早期、晚期并发症的例数,并发症出现后补救处理的操作时间,操作视野清晰度及需行急诊开腹手术例数。结果预处理组并发症总发生率明显少于对照组(6.98%比27.91%,P<0.05);出现并发症后处理所需时间也较对照组明显减少(8.0±1.78)min比(19.5±2.36)min,P<0.05)。晚期并发症、开腹手术病例、视野清晰度与对照组相比差异均无统计学意义(均P>0.05)。结论对结肠巨大息肉行预处理,再行息肉镜下切除,能减少并发症的出现,增加操作的安全性,且能减少出现并发症后处理所需时间。更多还原

Application of Pretreatment in Endoscopic Resection of Large Colonic Polyps

Objective To study the pretreatment of large colonic polyps with titanium clips and submucosal injection of norepinephrine, and to investigate the value of the pretreatment in endoscopic resection of large colonic polyps. Methods Eighty-six patients with large colonic polyps found on colonoscopy were randomly divided into pretreatment group and control group, with 43 patients in each group. After endoscopic resection of large colonic polyps, the number of patients with complications, remedial treatment time, operational vision clarity and number of patients requiring emergency laparotomy were recorded in both groups. Results Compared with control group, the pretreatment reduced the incidence of complications （6.98%vs 27.91%, P〈0.05） and shortened the time of remedial treatment （8.0 ±1.78）min vs （19.5 ±2.36） min, P〈0.05]. There were no significant differences in the incidence of late complications, number of patients undergoing laparotomy and operational vision clarity between the two groups （P〉0.05）. Conclusion Endoscopic resection of large colonic polyps after the pretreatment can reduce the occurrence of complications, increase the safety of operation, and shorten the time of remedial treatment.
