Introduction:
Gastrointestinal stromal tumours (GISTs) are the most common malignant subepithelial lesions of gastrointestinal tract, originating from Cajal's cells and characterized by the over expression of tyrosine kinase receptor C-KIT. The prognosis of this disease is associated with tumour size and mitotic index. Standard treatment of a GIST with no metastasis is surgical resection.
Presentation of case:
We report a case of a 75-year-old Caucasian man with unknown voluminous gastric GIST, who came to our attention complaining black stool. We decided to perform a laparoscopic-endoscopic combined surgical approach. Intraoperative gastroscopy identified the gastric GIST and confirmed the submucosal origin and the integrity of the tumor capsule. A 10 cm laparoscopic gastrotomy was carried out along the gastric fundus in order to realize a laparo-endoscopic rendez-vous procedure.
Discussion:
Laparoscopic approach is feasible and safe for Gastric GIST both in elective and urgent settings. Even for lesions greater than 5 cm, laparoscopy shows a recurrence rate similar to open surgery when radical resection are performed. An important point to take in consideration is surgical team experience, which seems to be one of the most important factors reducing the incidence of operative complications with better long-term outcomes, both postoperative and oncological.
Conclusion:
Mini-invasive approaches for gastric GIST are safe and feasible. The combined approach both laparoscopic and endoscopic has shown to be an effective technique and it may allow a better exposure of the tumour which ensure a radical resection.
