Background: Endophytic submucosal masses at anatomically difficult locations such as lesser curve of the stomach, juxta-gastroesophageal junction and duodenum are challenging to resect laparoscopically due to proximity of vital structures and difficulty to visualise them. To overcome these limitations, we describe a technique of endoscopic tattooing with indocyanine green (ICG) injection into the lesion allowing easy identification and oncological resection in a minimally invasive manner. Patients and Methods: The technique of endoscopic tattooing of the lesion and robotic transgastric eversion resection technique is described in patients with gastrointestinal tumours at difficult anatomical location. Results: Gastric gastrointestinal stromal tumours at the lesser curve (n = 3) and gastroesophageal junction (n = 1) were resected using this technique successfully. Conclusion: The use of intraoperative ICG tattooing of endophytic submucosal lesions at difficult locations can facilitate minimally invasive oncologic resection. This technique allows the surgeon to be more comfortable to approach complex lesions safely to improve patient outcomes.
