| Adenoma | 543 (69.5) | 402 (51.5) | 141 (18.1) | 8 |
| Sessile serrated lesion | 26 (3.33) | 13 (1.66) | 13 (1.66) | 0 |
| Hyperplastic polyp | 115 (14.7) | 37 (4.74) | 78 (9.99) | 1 |
| Malignant neoplasm | 16 (2.05)b | 4 (0.51) | 12 (1.54) | … |
| Non-polyps(colonic mucosa, lymphoid hyperplasia, and lipoma) | 81 (10.4) | 52 (6.66) | 29 (3.71) | 0 |
| Total polypectomies | 781 (100)c | 508 (65.0) | 273 (35.0) | 9 |
