Prospective Controlled Clinical Trial for Comparison of Tumor Efficacy Safety in Laparoscopic Resection of Gastrointestinal Stromal Tumors Between Favorable and Unfavorable Site（FUGES-016）
Participants with gastrointestinal stromal tumors(GIST) were divided into favorable and unfavorable sites according to the anatomical site of the tumor, and this study aims to validate the overall postoperative morbidity and mortality rates between favorable site receiving laparoscopic resection of GIST and that of unfavorable site under the currently standard surgical therapy.
• Age between 18 and 75 years old
• Primary gastric lesion confirmed pathologically GIST by endoscopic biopsy. Preoperative endoscopy, ultrasound endoscopy or computer tomography, Magnetic resonance suspected GIST, and then postoperative pathology confirmed as the original GIST
• Written informed consent
• Expected R0 resection by laparoscopy
• Performance status of 0 or 1 on the ECOG (Eastern Cooperative Oncology Group) scale
• ASA (American Society of Anesthesiology) class I to III
• Maximum tumor diameter ≤10cm
