Vascularized lymph node transfers have multiple donor sites with risk of iatrogenic lymphedema. We sought to describe in detail a surgical technique that is safe, reproducible, and efficient in harvesting gastroepiploic vascularized lymph nodes using real-time indocyanine green (ICG) fluorescent imaging. Photographs and video were acquired from a case to depict a step-by-step approach. ICG was endoscopically injected into the submucosa of the greater curvature of the stomach at the outset of the procedure. A laparoscopic harvest of the gastroepiploic vascular pedicle and lymph nodes ensued with the assistance of fluorescent imaging. Laparoscopic gastroepiploic lymph node harvesting aided by real-time ICG fluorescent mapping technique is safe, feasible, and effective at gathering vascularized lymphatic tissue for successful lymph node transfer in patients with severe lymphedema.
