The cases of local recurrence were identified.
2023 | Year | 01 | Month | 04 | Day |
This prospective, single-arm, observational study was performed at eight Japanese tertiary institutions. Colorectal lesions >=10 mm were resected endoscopically, and the pathological diagnosis was either an SSL or hyperplastic polyp (HP). Follow-up colonoscopy was performed 1 year later, and the local recurrence was evaluated by biopsy.
Those patients who resected polyps >=10mm, pathologically diagnosed either as SSL or HP were recruited.
Two post EMR bleedings were managed by endoscopy.
Among the 95 patients with 113 lesions who underwent follow-up colonoscopy, resection scars were identified in 95 (84%) lesions. Three (3.1%; 95% confidence interval 0.6-8.7%) local recurrences were diagnosed pathologically among 98 pathologically diagnosed SSLs.
