What should be the surveillance colonoscopy following sessile and laterally spreading adenomas?
High rates of residual adenoma are identified following a piecemeal resection of large (generally regarded as >2cm in size) and sessile adenomas. If there is doubt about whether the index lesion has been totally removed, the next colonoscopy should be done within three to six months.

|What should be the surveillance colonoscopy for patients at low risk (1-2 small tubular <10mm adenomas)? and What should be the surveillance colonoscopy for patients at high risk (>2 and ≥10mm adenomas or with HGD)?).If large and sessile adenomas are removed piecemeal, follow-up colonoscopy should be at three to six months and again at twelve months to ensure complete removal. If removal is complete, subsequent surveillance should then be based on histological findings, size and number of other adenomas (as set out in||B|
