Summary
Brief summary (as posted)
Despite laparoscopic surgical treatment has not been recommended in patients with gastric gastrointestinal stromal tumors (GIST) larger than 5 centimeter, but it continues to evolve rapidly to overcome the boundaries. Therefore the authors generated a morpho-anatomical classification system (MACS) adapted for primary gastric GISTs, by which they could plan to tailor the laparoscopic gastric resection appropriately. The aims of the study was to demonstrate the feasibility of laparoscopic surgery for primary gastric GISTs larger than 5 cm, to find out the accuracy and practicality of the MACS for the development a preoperative strategy and the extent to which this strategy overlaps with the reality.
