RESUMO
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.

The purpose of this study is to review the clinical and pathological features of pseudomembranous colitis in Korea. Ten cases of psedomembranous colitis, which were diagnosed by sigmoidoscopy and biopsy at the Seoul National University Hospital from May 1982 to occtober 1985, were analyzed in terms of the age and sex distribution, underlying diseases, presumptive causative antimicrobials, symptomatology, involved site and tratment. 1) The disease was more prevalent above sixth decade with a slight preponderance on the female. 2) The underlying diseases of the patients were the uterine cervix cancer in 3 cases and one case each of the nasal polyp, cataract, degenerative arthritis, tuberculous gradmuloma, SLE with menngitis, CVA and gingival abscess. 3) As for the presumptive causative drugs, cephalosporin were assaciated in 6 cases, aminoglycoside m 7 cases, penlcillin in 3 cases, Bactrim in 3 cases, antituberculosis drugs in 1 case and anticancer drugs in 1 case. 4) As for the anatotmical distribution of the lesion, the rectum was involved in 5 cases, the rectum and sigmoid colon in 4 cases and up to the descending colon in 1 case. 5) All the cases were cured by medical treatment. In 5 cases, discontinuation of the antimicrobial drugs and supportive care only were effective and in other 5 cases, vancamycin and/or metronidazole together vrith cholestyramine were added to the regimen.
