Nutritional Recovery after Open and Laparoscopic Distal Gastrectomy for Early Gastric Cancer: A Prospective Multicenter Comparative Trial (CCOG1204).

Background: Little information from prospective clinical trials is available on the influences of surgical approaches on postoperative body compositions and nutritional status. We designed a prospective non-randomized trial to compare postoperative chronological changes in body composition and nutritional status between laparoscopic and open distal gastrectomy for stage I gastric cancer (GC).

Methods: Body compositions and nutritional indicators in blood tests were measured at the baseline and at the 1st, 3rd, 6th, and 12th postoperative months (POM).
