Comparison of Tumor Efficacy Safety in Laparoscopic Resection of Gastrointestinal Stromal Tumors Between Favorable and Unfavorable Site

Summary

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.

7. History of unstable angina or myocardial infarction within the past six months
