RESUMO
BACKGROUD/AIMS: Obesity is a rising problem in industrialized countries. Numerous epidemiologic studies have shown a positive association between obesity and colorectal polyps. There are few studies investigating the association between colorectal adenomatous polyps and body fat composition in Korea. We tried to examine the relationship between body fatness and colorectal adenomatous polyps in health check-up subjects in Korea. METHODS: Six thousand seven hundred and six routine health check-up subjects, who visited our hospital between March 2002 and April 2005 and underwent distal colon examimation with sigmoidoscopy, were enrolled in this study. Among them, colonoscopy was done in 860 patients to evaluate the entire colon. We tried to reveal the relationship between body mass index (BMI) and size, location, number and histopathological type of polyps. BMI was used as an indicator of obesity. RESULTS: The mean value of BMI in total polyp-free group (23.8+/-2.9) was not different from that of the polyp group (24.5+/-2.8, p=0.09). The frequency of rectosigmoid polyps in obese patients (20.4%) was higher than that in non-obese patients (16.0%, p or =4) correlated well with obesity. Moreover, age and triglyceride level in patients with colonic adenoma were significantly higher than in patients without colonic adenom. CONCLUSIONS: This study shows that obesity is not associated with colonic adenomatous polyp in Korean population. However, we observed that obesity may be associated with rectosigmoid colon polyps. Furthermore, age and triglyceride level might be the risk factors of colonic adenomatous polyps in Korean population.

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.
