What is a recommended practice to prevent complications when injecting colonic lesions with india ink?

Clamping the bowel proximal to the lesion is a recommended practice when injecting colonic lesions with india ink to help prevent complications. This technique allows for better control of the injection site by reducing the movement of the bowel and minimizing the risk of spillage or leakage of the ink into surrounding tissues. By limiting bowel distension and ensuring the lesion remains accessible, the healthcare provider can achieve a more precise injection, which is critical for accurate visualization during subsequent procedures or assessments.

Ensuring that the area is stable helps in delivering the appropriate volume of ink to the intended site, enhancing the efficacy of the marking and reducing the risk of complications such as perforation or infection. This practice emphasizes the importance of control during endoscopic procedures, particularly when utilizing substances like india ink that are meant to delineate lesions for further treatment or assessment.
