Arms & Interventions
Targeted forceps biopsy
In this group, an endoscopist takes a forceps biopsy at depressed mucosa or large nodular area of large colorectal tumors after meticulous surface evaluation.
Intervention: Targeted group (Diagnostic Test)
Conventional forceps biopsy
In this group, an endoscopist takes a forceps biopsy at the most convenient area of large colorectal tumors.
Outcomes
Primary Outcomes
pathologic diagnosis
Time Frame: 7 days
The pathologic diagnosis of forceps biopsy is compared with the pathologic diagnosis of resected specimen of the colorectal tumor.
Secondary Outcomes
No secondary outcomes reported
