Abstract :Objectives: Endoscopic mucosal resection insert ignore into journalissuearticles values(EMR); has been widely used in early gastrointestinal malignancies and precancerous lesions. We aim to analyze the outcomes of EMR for gastrointestinal precancerous lesions. Materials and Methods: A total of 1,518 cases were retrospectively analyzed. Of these, 59 patients had undergone EMR for gastrointestinal lesions. The lesions were divided into two subgroups according to size; smaller than 20 mm and equal or larger than 20 mm. The mucosal aspect insert ignore into journalissuearticles values(Kudo pit pattern);, Paris classification of the resected lesions and recurrences that were determined during close follow-up were recorded. Results: A total of 94 polyps were resected in 59 patients. En-block resection was performed in 42 insert ignore into journalissuearticles values(71.2%); patients and piecemeal resection in 17 insert ignore into journalissuearticles values(28.8%);. There was no significant difference between two modalities; regarding age, gender, histopathology, complications, recurrence or macroscopic type insert ignore into journalissuearticles values(P>0.05);. However, the occurrence of Kudo type 4 lesions and adenomatous polyps insert ignore into journalissuearticles values(P=0.001); was significant in the >20 mm group insert ignore into journalissuearticles values(P=0.03);. Conclusion: Endoscopic mucosal resection is a safe and feasible procedure for precancerous lesions, with low complication and acceptable recurrence rates. Additionally, the Kudo pit pattern should be taken into consideration on a routine basis when determining the risk of cancer.
