...) followed up without surgery. When endoscopically resected T1 CRC was followed up without additional surgery, 70.0% (149/213) of the respondents performed the next follow-up colonoscopy within 6 months and 96.7% (206/213) within a year. For surveillance after resection of T1 CRC, the majority...

... was seen on follow-up colonoscopy in cases with incomplete resected polyps. Conclusion: CSP seems to be efficient and safe in removing colorectal polyps up to 15 mm. A hybrid snare seems to be particularly advantageous for these polyps as it allows immediate conversion to HSP if CSP might fail in larger...

Results: Among the 329 participants screened in the asymptomatic cohort, 78 subjects (23.7%) were in the low-risk (LR) tier, 187 subjects (56.8%) in the moderate-risk (MR) tier, and 64 subjects (19.5%) in the high-risk (HR) tier. The percentage of ACRN...

... on polyp detection rates is lacking. In this study, we report the effect of discontinuation of this practice on polyp detection rates. Methods: Procedure data of 4,254 consecutive colonoscopies were used. Patients underwent standard bowel preparation with polyethyleneglycol (Glycoprep®). Colonoscopies were...

...: Although colonic diverticular bleeding (CDB) often ceases spontaneously, re-bleeding occurs in about 30%. Bleeding diverticulum can be treated directly by endoscopic hemostasis; however, it is difficult to perform colonoscopy in all cases with limited medical resource and certain risks. The aim...
