Clinical utility of the SMSA grading tool for the management of colonic neoplastic lesions
2017
Abstract Background Whilst polyp size has been traditionally used as a predictor of the complexity of endoscopic resection, the influence of other factors is increasingly recognised. The SMSA grading system takes into account polyp Site, Morphology, Size and Access, with higher scores correlating with increased technical difficulty. Aims To evaluate whether the SMSA grading tool correlates with endoscopic and clinical outcomes. Methods This retrospective study was conducted at two high volume centres in the United Kingdom and Italy. All polyps identified at colonoscopy were included in this study and classified as per the SMSA grading system. Results A total of 1668 lesions were resected in 1016 patients. There was a positive correlation between increasing SMSA level and the inability to resect lesions “en bloc” (p Conclusions The SMSA grading tool is a useful predictor of outcome following the resection of colonic neoplastic lesions.
