Spot is Clinically-Proven and Society-Recommended
India Ink tattoos for the GI tract have been used by Gastroenterologists since at least the 1950s when Sauntry et al first described them. Ponsky et al. further studied their ability to facilitate locating colonic lesions in 1975. Since that time, the interest in tattooing colon lesions has only grown.
Spot Endoscopic Marker is supported by overwhelming clinical research
- Clinically proven through more than 25 published studies
- Clear value to endoscopists in clincal surveillance
- Colorectal Surgeons and Proctologists find lesions faster in surgical localization
Society Clinical Practice Guidelines Call for Tattooing
Consistent clinical evidence has led leading global societies to call for tattooing colon lesions for future procedures.
- “Colonoscopic tattooing is performed to enable future identification, at colonoscopy or surgery, of malignant lesions (proven or suspected), polypectomy, EMR, or ESD sites, difficult-to-detect polyps, or dysplastic areas. All such lesions, other than those definitely located in the cecum, adjacent to the ileocecal valve, or in the low rectum, should be tattooed.1” – ESGE 2017 Clinical Guideline: Colorectal Polypectomy and Endoscopic Mucosal Resection (EMR)
- “Tattooing of all lesions > 20mm and/or suspicious of cancer outside of the rectum and caecum should take place in 100% of cases following local trust guidance.”2 – BSG 2016 Clinical Guideline: Colonoscopy Key Performance Indicators
- “Lesions…should be marked with ample submucosal injection of carbon black [Spot] in 3 to 4 quandrants to ensure resection of the correct segment.”3
- “Tattooing is extremely important for intraoperative localization. Tattooing should be accomplished using suspended carbon black commercially-prepared for this product [Spot®]”4 – SAGES 2012 Clinical Guideline: Laparoscopic Resection of Curable Colon and Rectal Cancer

What is Spot for?
Spot is indicated for tattooing or “marking” lesions in the GI tract. Although commonly used for the future identification of colon cancer at colonoscopy or surgery, there are also other use cases throughout the GI tract. Researchers have shown the use of tattooing in Barret’s Esophagus1, Gastric Ulcers2, Double Balloon Enteroscopy3, and pancreatic lesion marking4.

Is Spot the same as India ink?
No, it is not. Spot Endoscopic Marker contains high purity, suspended carbon black particles in a ready-to-use, sterile, pre-filled syringe. Commercial India ink often contains impurities such as shellacs, phenols, ammonia and animal products. According to an ASGE technology report, these impurities have been associated with complications such as inflammatory reactions. In a 113 patient study of Spot, no inflammation, fever or abdominal pain was detected in any of the patients. Why take the risk of do-it-yourself commercial India inks when you have a sterile, ready-to-use, FDA cleared solution.
Is Spot sterile?
Yes, Spot is terminally steam sterilized. It can be stored in normal conditions in GI procedure rooms, and offers a sterile fluid path when connected to a standard injection needle. Spot goes a step further to not contain shellac, phenols or ammonia like other sterile India-ink products.
Is Spot FDA cleared?
Yes, Spot received FDA clearance as a medical device for tattooing lesions in the GI tract.

Do I have to combine and mix the ingredients of Spot?
No. Spot is packaged in a pre-filled, ready-to-use syringe. It’s luer-lock connection works with any standard injection needle to reduce the risk of spills, stains, and needle-stick injuries. With a quick shake to disperse the carbon particles, the syringe is ready to use.

How do I inject Spot?
0.5-0.75ml of Spot should be injected submucosally into four quadrants distal to the lesion of interest. Use a 23 or 25 gauge injection needle at an angle so that the beveled tip of the needle is entirely beneath the mucosa. If the needle is inserted perpendicular to the mucosa, there is a risk of penetrating the serosa and injecting the marker directly into the peritoneal cavity.

How do I store Spot?
Spot can be stored at room temperature, with the syringe tips pointing up, for up to two years. Most facilities store Spot directly in the GI procedure room, to ensure it’s available when you need it.
How do I order Spot?
Spot is available in boxes of 10 pre-filled syringes, as catalog number GIS-44. Give us a call or complete the GI Supply Orders Form and send it to customer service via e-mail or fax.

Methods to Inject Endoscopic Tattoo into the Submucosal Space with Dr. Douglas K. Rex
Two methods that can be used to effectively administer endoscopic tattoos into the submucosal space are the direct and bleb techniques. In this video, Dr. Douglas K. Rex of the Indiana University School of Medicine demonstrates how to tattoo using a direct injection technique, and how to tattoo by using a saline bleb.
