目的 观察内镜下微波治疗消化道息肉的效果。 方法 进行了体外实验和临床研究。患有食管、胃或结肠息肉的120例患者,采用微波功率90 mA、时间6 s/次、依息肉大小决定点灼次数和调节天线插入组织深度的方法。 结果 凝除息肉134颗,其中特大息肉(4cm×3cm-5cm×4cm)5颗。131颗经1次治疗后息肉完全脱落(97.8％)。最早复查时间为治疗后第5d,息肉已脱落,仅遗留浅溃疡。5例特大息肉分别点灼16-30次后均1次性脱落。 结论 微波是治疗无蒂或亚蒂状息肉的安全、有效方法。在微波治疗中,不必强调使息肉出现白色凝固或达到汽化或碳化。使息肉变色、萎缩即可。微波为特大息肉的治疗开辟了一条新的途径。
Objective To observe the effect of endoscopic microwave treatment of gastrointestinal polyps. Methods In vitro experiments and clinical studies. 120 patients with esophageal, gastric or colonic polyps were treated with a microwave power of 90 mA for 6 s / time, the number of burns depending on the size of the polyp, and the method of adjusting the depth of insertion of the antenna into the tissue. Result coagulation polyp 134, including extra-large polyps (4cm × 3cm-5cm × 4cm) 5. The polyps completely detached after 131 treatments (97.8%). The earliest review for the first 5d after treatment, polyps have been shed, leaving only shallow ulcers. Five cases of extra-large polyp were burning 16-30 times after a one-off. Conclusion Microwave is a safe and effective method for the treatment of pedunculated or pedunculated polyps. In the microwave treatment, do not have to emphasize the polyp white solidification or to achieve vaporization or carbonization. Polyp color, shrinking can be. Microwave for the treatment of extra-large polyps opened up a new way.
