Summary
The study is designed to elucidate whether carbon black suspension endoscopic tattoo enhances visibility of lymph nodes or tumor tissue on dissection of colonic surgical specimen, thereby making improvement in staging defined as better pTNM stage via better visualisation of carbon marked metastatic or sentinel lymph nodes or marked primary tumor or adjacent tissues.
Description
Other objectives are:
- to assess intraoperative visibility of carbon black tattoo in the tumor region and surrounding tissues
- to assess microscopic distribution of carbon ink in the layers of the colonic wall and adjacent tissues
- to assess complications related to carbon black tattoo procedure like microscopic fibrosis, micro- or macroscopic scarring, inflammatory reactions
- to assess long-term effects of ink injections on control endoscopies at 6 and 12 months
- to assess dissection time in tattooed-non tattooed lymphatic tissues
