Feasibility of cold XXXX polypectomy in Japan: A pilot study.

AIM: To investigate the feasibility of cold @entity24332 polypectomy (CSP) in Japan. METHODS: The outcomes of 234 non-pedunculated @entity1127 smaller than 10 mm in 61 @entity1 who underwent CSP in a Japanese referral center were retrospectively analyzed. The cold @entity24332 polypectomies were performed by nine endoscopists with no prior experience in CSP using an electrosurgical @entity24332 without electrocautery. RESULTS: CSPs were completed for 232 of the 234 @entity1127 . Two (0.9%) @entity1127 could not be removed without electrocautery. Immediate postpolypectomy @entity548 requiring endoscopic hemostasis occurred in eight lesions (3.4%; 95%CI: 1.1%-5.8%), but all were easily managed. The incidence of immediate @entity548 after CSP for small @entity1127 (6-9 mm) was significantly higher than that of diminutive @entity1127 ( <= 5 mm; 15% vs 1%, respectively). Three (5%) @entity1 complained of minor @entity548 after the procedure but required no intervention. The incidence of delayed @entity548 requiring endoscopic intervention was 0.0% (95%CI: 0.0%-1.7%). In total, 12% of the resected lesions could not be retrieved for pathological examination. @entity5 involvement in the lateral margin could not be histologically assessed in 70 (40%) lesions. CONCLUSION: CSP is feasible in Japan. However, immediate @entity548 , retrieval failure and uncertain assessment of the @entity5 margin should not be underestimated. Careful endoscopic diagnosis before and evaluation of the @entity5 residue after CSP are recommended when implementing CSP in Japan.
