Overview
The purpose of this study is to explore the safety of laparoscopic resection of 5cm or larger gastric gastrointestinal stromal tumors
Description
There is a lack of high-quality evidence on the efficacy and safety of laparoscopic resection of gastric GIST over 5cm. A multicenter, prospective cohort study was conducted to evaluate the clinical efficacy of laparoscopic resection of 5cm or larger gastric gastrointestinal stromal tumors (GIST) compared to laparoscopic resection of GIST of less than 5cm. The primary evaluation parameter is overall postoperative morbidity.
Eligibility
Inclusion Criteria:
- 18 years < age < 75 years

- Patient informed consent and willingness to undergo laparoscopic resection
- Expected laparoscopic outcome of R0 resection
- Performance status: Eastern Cooperative Oncology Group (ECOG) ≤ 2, Preoperative American Society of Anesthesiologists（ASA） score I-III
Exclusion Criteria:
- Women during pregnancy or breast-feeding
- Severe mental disorder
- History of upper abdominal surgery (except the history of laparoscopic cholecystectomy)

- History of other malignant diseases within the past five years
- History of unstable angina or myocardial infarction within the past six months
- History of a cerebrovascular accident within the past six months
- History of continuous systematic administration of corticosteroids within one month
- Requirement of simultaneous surgery for other diseases
- Emergency surgery due to complications (bleeding, obstruction, or perforation) caused by gastric cancer
