💡 5 Key Tips for the Perfect India Ink Tattoo
1. Choose the right needle and prime it with normal saline. The normal saline will fill-in the dead space within the needle channel and is the essential part of this technique.
2. Advance needle through the scope and choose a spot for injection, usually 3 cm proximal to the tumor. NEVER inject below a polyp as ink will create a fibrotic reaction and impede proper removal of the polyp.

3. Placement of needle in relation to mucosa. Opt for an oblique, if possible, almost tangential position rather than a squared angle position one for more accurate submucosal tattooing. Injecting into the peritoneum will result in spillage, irritation and creation of reactive granulomas and nodules, which may mimic infection, tumor or endometriosis.
4. Create a submucosal cushion with the saline inside of the needle. The India ink syringe is connected to the needle and injected slowly. This pushes the saline out of the needle, to form a cushion before the ink arrives, to prevent intraperitoneal injection and ensure a localized tattoo.
5. Use the right amount of ink. Typically, half to one milliliters of India ink is sufficient to create a clear and lasting tattoo.
