Nonpolypoid colorectal neoplasms: a challenge in endoscopic surveillance of patients with Lynch syndrome

Abstract: 

Conclusions: 
In patients with Lynch syndrome, colorectal neoplasms are more likely to have a nonpolypoid shape than those from average risk patients, especially in the proximal colon. These findings suggest that proficiency in recognition and endoscopic resection of nonpolypoid colorectal lesions are needed to ensure colonoscopic prevention against CRC in this high risk population
