title: Endoscopic tattooing of colorectal lesions: Is it a risk-free procedure?
abstract: Endoscopic tattooing is one of the most useful tools for the localization of small colorectal lesions especially in the laparoscopic setting. This is a minimally invasive endoscopic procedure without risk of major complications. However, many studies have revealed complications resulting from this procedure. In this article, several topics are reviewed including the accuracy, substance preparation, injected techniques and complications related to this procedure.
