A laparoscopic approach to surgical resection of gastric GIST is associated with low morbidity and short hospitalization. As found in historical series of open operative resection, the tumor mitotic index predicts local recurrence. The long-term disease-free survival of 92% in our study establishes laparoscopic resection as safe and effective in treating gastric GISTs. Given these findings as well as the advantages afforded by minimally invasive surgery, a laparoscopic approach may be the preferred resection technique in most patients with small- and medium-sized gastric GISTs.

Initial clinical results from the use of EBVS in laparoscopic and open procedures demonstrate it to be safe and effective, reducing operative time in open procedures. Suture ligatures, ties, hemoclips, and other ligating techniques were used rarely (0.3%) after an application of the EBVS. In an experimental animal model, the EBVS was significantly faster and more efficient (more applications per minute) than ligatures for intestinal resection.

Laparoscopic resection of gastric stromal tumors is safe and appropriate. Tumor size, operating time, and estimated blood loss were equivalent to the open approach, and there was a statistically shorter hospital stay in the laparoscopic group.
