Conditions

Colorectal Cancer

Interventions

Application of fat dissociation method on the resected mesentery of colon and rectum. Lymph nodes will be searched for after fat dissolution.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: (1) A patient has diagnosis of colorectal (Rb rectal cancer is excluded) cancer via endoscopic and/or pathological examination. (2) Distant metastasis is absent. (3) A patient is 20 years old or older. (4) A patient is able to fully understand the present study, and provide written informed consent.

Exclusion criteria

Exclusion criteria: When the investigator consider it inappropriate to include the patient into this study

Design outcomes

Primary

Measure	Time frame
Comparison of the number of retrieved lymph nodes obtained by conventional method and that obtained by new method	—

Secondary

Measure	Time frame
The difference of retrieved lymph nodes number between institutes, reporting microscopic observation of retrieved lymph nodes, stainability of metastatic tumors to tumor specific markers, the diameters of positive lymph nodes. As explorative study, the remnant mesentery will be further incubated with fat dissolution liquid. Lymph nodes, if any, will be microscopically observed to clarify the effect of longer incubation at 40 degree.	—
