内镜下切除胃肠道息肉及癌前病变方法的选择

CLINICAL ANALYSIS OF DIFFERENT VARIETIES OF CUTTING GASTROINTESTINAL POLYP AND PRECANCEROUS LESION

目的 :比较不同方法切除胃肠道息肉和癌前病变的疗效。方法 :本文采用高频电和其它不同方法对胃肠道息肉和癌前病变切除和切割。结果 :对小的扁平息肉用高频电灼除或热活检安全有效。一次灼除达10 0 %。圈套适应胃结肠有蒂息肉。对大的有蒂或分叶状息肉需分次圈套切除 ,圈套和烧灼或热活检结合可避免肠穿孔发生。双胃镜代替双腔治疗胃镜行粘膜切除术切除胃内平坦和扁平隆起性非典型增生灶操作容易 ,病灶切除彻底。息肉切除后常于局部形成溃疡 ,术后应常规给予酸抑制剂和粘膜保护剂治疗。结论 :内镜 -高频电是切除胃肠道有蒂和无蒂息肉的有效方法 ,粘膜染色后 。

Objective:To compare effects of different varieties of cutting gastrointestinal polyp and precancerous lesion. Methods:High frequency currents and other methods were made for cutting gastrointestinal polyp and precancerous lesion. Results:It is safe and effective to resect the little flat polyp by high frequency currents coagulation or hot biopsy. All polyp are extirpated in only one procedure. Snare is suitable for the polyp with stem. Big polyp with stem or leafy polyp can be resected by snare in many times. Snare combined with coagulation or hot biopsy can avoid perforation of intestine. Double endoscopies take the place of double holes endoscopy to resect flat by mucosectomy. This method is complete for resection. The ulcer appears after polypectomy. Medicines which suppress the secretion of gastric acid and protect gastric mucosa were applied routinely after operation. Polyp with stem located in the esophagus and stomach are resected by ligation. It is safe and effective. Conclusion:Endoscopic high frequency currents was effective method for resecting the gastrointestinal polyp. After mucosa stained, mucosectomy with double endoscopies in the treatment of precancerous lesion was feasible method.
