OBJECTIVE: To analyze the results of minimally invasive surgical procedures in patients with gastric GIST.
MATERIAL AND METHODS: The study included 30 patients aged 52.2±9.8 years. ASA grade II (44%), III (26%) and I (23%) were predominant. Lesion of stomach body was noted in 17 (56%) patients, antrum - in 8 (27%), fundus - in 2 (7%) and cardia - in 3 (10%) patients. GIST was located on the anterior wall of stomach in 56% of patients. Exophytic growth was observed in 16 (53%) patients, endophytic - in 12 (40%), transmural growth - in 2 (7%) cases. T2 grade of tumor was noted in 67% of cases (TNM 8). All patients underwent laparoscopic or robot-assisted ('daVinci Si') partial resection of the stomach.
RESULTS: Radical resection (R0) without injury of pseudocapsule of tumor was made in all patients. Laparoscopic procedures were performed in 25 (83%) patients, robot-assisted - in 5 (17%). Early postoperative complications (Clavien-Dindo II) were observed in 3 patients. Spindle cell structure of tumors (93%) with low mitotic activity (63%) prevailed. Tumor stage I was observed in 56% of patients. Patients with high mitotic tumor index (44%) were directed to targeted therapy. Recurrence and/or metastasis in long-term period were absent in 26 (87%) patients.
CONCLUSION: Laparoscopic surgery for gastric GIST is safe and characterized by the absence of significant postoperative complications and long-term recurrence-free period. The use of robotic surgical system is effective and justified for anatomically difficult localization of GIST.
