Equivalent feasibility and safety of perioperative care by ERAS in open and laparoscopy-assisted distal gastrectomy for gastric cancer: a single-institution ancillary study using the patient cohort enrolled in the JCOG0912 phase III trial
Laparoscopy-assisted distal gastrectomy (LADG) has an advantage of earlier recovery after surgery due to having lower invasiveness and wound pain than open distal gastrectomy (ODG). However, whether the same e...

Does a laparoscopic approach attenuate the body weight loss and lean body mass loss observed in open distal gastrectomy for gastric cancer? a single-institution exploratory analysis of the JCOG 0912 phase III trial
Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer may prevent the loss of body weight and lean body mass resulting from reduced surgical stress in comparison to open distal gastrectomy (ODG). A...
