Where and when to tattoo colonic neoplasms prior to resection is a hotly debated topic. We are interested in experiences of colorectal surgeons globally to inform a potential prosepctive study into common problems and how to avoid them.
i think tattooing is really important in following up border-line lesions treated by local excision( polipectomy) less important in localizing the tumor prior to resection
No, no negative issues. May fade at different speed, depending on patient type and related perfusion. Clipping may be easier to find as you can xrays. or you combine both.
The more frequent problem is not finding the ink in the rectum surface, which is the most relevant place. Less frequently an excess of diffusion makes a big spot extending over a big surface, darkening the real distal limit of resection. Most of the times, of course, tattooing works well.
