Incomplete resection of colon polyps is considered to be an important cause of colorectal cancer
.
It is estimated that incomplete polypectomy accounts for 10%-30% of all colorectal cancers after colonoscopy
Incomplete polypectomy for colorectal cancer accounts for 10%-30% of all colorectal cancers after colonoscopy Incomplete polypectomy accounts for 10%-30% of all colorectal cancers after colonoscopy
This is an observational cohort study to investigate the risk of recurrence after incomplete resection of colorectal polyps
.
The test patients were patients with colon polyps with complete or incomplete resection records who had 5-20 mm tumor polyps surgically removed, and were monitored and examined
.
The definition of segmental metachronous neoplasia: the proportion of colon segments with at least one tumor polyp at the first monitoring examination
Polypectomy in the test patient
Polypectomy in the test patientAmong the 233 patients tested, 166 (71%) had received at least one surveillance examination
.
Compared with complete polyp resection, the median time before monitoring examination after incomplete polyp resection is significantly shorter (17 vs 45 months)
The risk of metachronous tumors in intestinal segments where polyps are not completely removed is significantly higher than the risk of metachronous tumors in bowels where polyps are completely removed

The number of polyps in the bowel incomplete resection of recurrent polyps are also more number of bowel polyps incomplete resection of recurrent polyps are also more risk of advanced adenoma is also a higher risk of advanced adenoma is also higher polyps with incomplete resection The strongest independent factor associated with metachronous tumors
In summary, the study found that the risk of future neoplasia and late neoplasia of the colon segment with incomplete polypectomy was significantly increased compared with that of the colon segment with complete polyp resection

Compared with the colon segment where the polyp is completely removed, the colon segment where the polyp is not completely removed has a significantly higher risk of future neoplasia and late neoplasia
