Introduction. Open surgery is considered the surgical gold standard for the treatment of gastric stromal tumors. Some recent studies propose laparoscopic surgery as a safe alternative. We conducted a systematic review of the literature to assess the effectiveness and safety of the laparoscopic approach in comparison with the open approach evaluating operative time, hospital length of stay, complications and tumor recurrence Material and methods. We conducted a systematic review of the literature and evaluated the quality of the available studies, selecting those of higher quality using the JAMA criteria. The Best BETS methodology was followed. Results. Three systematic reviews of observational studies but none randomized controlled trial were found. Patients in the laparoscopic group had shorter time until feeding and hospital length of stay and lower number of minor and severe complications. In comparison with open surgery, there is no difference regarding blood loss and operating time. Recurrence and disease free survival were similar. Conclusion. Evidence form observational non randomized trials suggest that laparoscopic surgery for GIST gastric tumors is as safe and effective as the open approach. Applicability of laparoscopic techniques requires a careful evaluation of factors such as patient conditions, tumor size, location, invasion and experience of surgeons to guarantee a successful outcome.
