Gastrointestinal stromal tumour (GIST) of the stomach is extremely rare in the elderly. Surgical resection of the stomach by partial gastrectomy or wedge resection is the standard treatment. Today the resection can also be performed laparoscopically, especially in the case of small tumours as well as for larger GIST though there are unclearly defined oncological limits. The authors report the successful treatment of a large 7.5 cm GIST of the stomach by laparoscopic wedge resection in a 78-year-old patient. The GIST was almost entirely located intraperitoneally between the stomach and the spleen and could be radically resected with a minimal touch technique. The patient recovered promptly and manifested no recurrence at a 2-year follow-up. The authors focus on the main factors supporting the indication for laparoscopic resection of large gastric GIST, especially in the elderly. The surgical risk/benefit ratios of the different approaches, the surgeon's skills in laparoscopically respecting the rules of oncological surgery, and informed consent of the patient in relation to the limited scientific evidence concerning the main risk factors of recurrence are all important considerations.
