Gi Supply Inc. reports that Spot Ex is now indicated for clinical surveillance in addition to surgical localization. Leading societies recommend tattooing of malignant lesions, post-polypectomy sites, and difficult-to-detect polyps to enable future identification at follow-up colonoscopy or surgery.1

Recently published national data highlighted that colon cancer incidence and mortality rates are rising in younger patients.2,3 Additionally, new clinical guidelines have been released from the European Society Gastrointestinal Endoscopy (ESGE) that recommend tattooing all lesions that need to be followed-up at future colonoscopy or surgery.1

Spot Ex helps clinicians combat these trends and implement the guidelines by offering expanded indications that include long-term clinical surveillance. The new Spot Ex Endoscopic Tattoo provides a permanent mark, enabling a lifetime of patient care follow-up. Spot Ex is also 50% darker than the current Spot product, making the tattoo easier-to-find4 and helping endoscopists and surgeons manage time and productivity pressures.

“As a therapeutic endoscopist at Northwestern Memorial Hospital, I am often referred complex polyp removal cases. In those scenarios, it is very beneficial to have the polyp tattooed for easy identification,” said Dr. Sri Komanduri, Gastroenterologist. “In addition, post-resection I typically follow-up with the patient within six months to ensure there is no adenoma recurrence, and a tattoo helps with that surveillance. The new Spot Ex tattoo will help me monitor that patient as long as needed.”

“In my practice at San Antonio Gastroenterology Associates we have seen a steady increase in young patients being diagnosed with colon cancer. Fortunately, earlier diagnosis and new endoscopic therapies we offer are working,” said Dr. Antonio Serna, Gastroenterologist. “But these patients need to come back for many years of surveillance. Spot Ex gives me a way to feel confident in my assessment of cancer remission or recurrence.”

“We’re excited to aid in the fight against colon cancer and advance the science of endoscopic tattooing with a permanent and cost-effective solution for gastroenterologists and surgeons. Our mission at GI Supply is to help more GI physicians do more advanced endoscopic procedures safely and efficiently, and Spot Ex is a great next step in meeting those needs,” said Luke Johnson, CEO of GI Supply.
