Indocyanine Green is an Ideal Dye for Endoscopic Ultrasound-Guided Fine-Needle Tattooing of Pancreatic Tumors

Endoscopic ultrasound-guided fine-needle tattooing (EUS-FNT) is an ideal technique for preoperative marking of lesions detected on preoperative examination. Although India ink has been used for endoscopic tattooing, there have been numerous reports of complications associated with its use. This is the first report of EUS-FNT using indocyanine green (ICG) and describes its use for preoperative marking of a tumor in a 78-year-old man with multiple pancreatic tumors. There were no complications associated with the EUS-FNT procedure and it is suggested that ICG is a more suitable dye for tattooing of pancreatic lesions than India ink, being far less frequently associated with side effects.
