摘要
目的评价钛夹对结肠大息肉电切时预防出血的效果。方法将67例(82颗大息肉)结肠大息肉的病人随机分为对照组及钛夹组。对照组34人,共39颗息肉,息肉平均直径22cm;钛夹组33人,42颗息肉,息肉平均直径2.5cm。先用钛夹钳夹息内的根部,平均每颗息肉1.4个止血夹,然后行息肉电切术。术后观察两组疗效及出血、穿孔发生率。用染色放大结肠镜观察随访。结果对照组一次性息肉完全切除率为100%(39/39),钛夹组为97,6%(41/42,P〉0.05)。对照组病理检查:腺瘤型息肉占92.3%(36/39),其余为增生性息肉。25%的腺瘤性息肉伴轻度非典型增生,2.8%的伴中度非典型增生和2.8%伴有癌变。钛夹组腺瘤性息肉占95.2%,其余为增生性息肉。27.5%的腺瘤性息肉伴有轻度非典型增生,7.5%的伴有中度非典型增生和7.5%的伴有癌变。术后3、6、12个月用染色放大结肠镜观察随访,未见残留癌灶和复发征象。钛夹组出血发生率为0%,明显低于对照组的12.8%(P〈005)。钛夹组无穿孔病例,对照组中1例发生小穿孔,两组无显著性差异(P〉0.05)。结论钛夹钳夹结肠大息内后仍可完整地电切该息肉,包括癌变的息肉,并且比普通电切术减少出血发生率。
AIM To evaluate the efficacy of hemoclip application in the prevention of bleeding after endoscopic resection of colonic polyps. METHODS; Sixty - seven patients with colonic polyps were randomly divided into two groups receiving polypectomy with (n= 33) or without(n = 34)hemoclipping. RESULTS Post polypectomy bleeding rate was higher for patients treated without than with hemoclips ( 12.8 % vs 0 %, P 〈 0.05). CONC1,USION Hemoclipping can effectively reduce the incidence of post- polypectomy bleeding.
