Abstract
The gastric polyps may be premalignant lesions and they should be removed as possible. The gastric polyps can be remoued by various endoscopic methods. The safety and therapeutic effectiveness of snare polypectomy, neodymium YAG laser therapy and electrocutery were compared in a total number of 106 patients who were diagnosed as benign polyps by means of endoscopic biopsy.Safety was evaluated by the rate of complications such as perforation and bleeding, and therapeutic effectiveness was evaluated by the average numbers of treatment session of each modality. Average numbers of treatment session of snare polypectomy, laser therapy and electrocautery were 1.04, 1.38 and l.44, respectively. Average numbers of treatment session of snare polypectomy were significantly (p<0.05) lower than those of other two methods. Perforation was not occurred in any group. Bleeding rates after snare polypectomy, laser therapy and electrocautery were 17.4%, 1.0% and 3.8%, respectively. Bleeding was significantly (p<0,05) more frequent after snare polypectomy than after other two methods. In conclusion therapeutic effectiveness was best in snare polypectomy but complication was most frequent after snare polypectomy. There was no difference between laser therapy and electrocautery for therapeutic effectiveness and safety. Therfore, laser therapy and electrocautery caa be used for the removal of flat adenoma, alternatively.
