| Postoperative remnant stomach volume (mL) | 225.6±118.3 | 99.1±63.2 | 0.001 | ||||
| Removed stomach volume (mL) | 276.3±115.9 | 480.8±167.9 | 0.004 | ||||
| Postoperative stomach volume decrease (%) | 55.4±21.4 | 84.0±4.9 | 0.000 | ||||

PAAP = proximal anterior wall-antrum posterior wall; LAPPG = laparoscopy-assisted pylorus-preserving gastrectomy; SR = segmental resection; PPG = pylorus-preserving gastrectomy.
