Laparoscopic-assisted distal gastrectomy (LADG) is rapidly gaining in popularity. However, there is limited evidence regarding its oncologic safety. We conducted a phase III multicenter, prospective, randomized study comparing LADG with open gastrectomy. We found no significance difference in the morbidity and mortality between the LADG and open gastrectomy groups. Therefore, we conclude that this trial was safe and is thus ongoing.
