Three cases are presented including a 3 cm GIST in the fundus of the stomach, an 8cm GIST off the lesser curve of the stomach, and a 2cm GIST at the gastroesophageal junction. Advanced laparoscopic techniques are described to approach gastric GIST resections. Key points include adoption of other surgical techniques from the gastric sleeve, identification of critical vasculature with dissection and enucleation near the GIST, as well as a transgastric approach.
