Laparoscopic pylorus-preserving gastrectomy (LPPG) has been introduced as a minimally invasive function-preserving operation for early gastric cancer (GC). This study aimed to investigate the surgical and prognostic outcomes after LPPG at the authors’ institution.


This study analyzed 465 patients who underwent LPPG for cT1 N0 GC located in the middle part of the stomach between 2006 and 2012. Short- and long-term surgical outcomes including 5-year survival rates, postoperative nutritional data, and body weight change were retrospectively investigated.


Regarding short-term surgical results, 14 (3%) of the 465 patients had severe complications classified as Clavien–Dindo grade 3a or above, and no mortality occurred (no in-hospital deaths). The median follow-up period was 1829 days (range 226–3197 days), and the 5-year overall survival and relapse-free survival rates were respectively 98% (95% confidence interval [CI] 96.1–99.0%) and 98% (95% CI 96.1–99.0%). Only two cases of postoperative recurrence were confirmed, and their recurrence sites were not in the remnant stomach or regional lymph nodes. The postoperative nutritional status, in terms of serum total protein, albumin, and hemoglobin levels, was well maintained, and the mean relative body weight (postoperative/preoperative) was 93.24 ± 7.29% after LPPG.


For the first time, we have clarified the detailed long-term survival outcomes of LPPG for cT1 N0 GC. LPPG is an acceptable and favorable operative method for clinically diagnosed early-stage GC, in terms of long-term survival and postoperative nutrition.
