I	23 (92.0%)
II	2 (8.0%)
III	1 (4.0%)
Number of sentinel lymph nodes	12.8 ± 7.2
Length of sentinel basin
Lesser curvature (cm)
Proximal length of sentinel basin	3.7 [2.0–5.0]
Distal length of sentinel basin	3.0 [2.3–5.5]
Greater curvature (cm)
Proximal length of sentinel basin	6.8 [3.5–11.0]
Distal length of sentinel basin	7.0 [3.8–9.5]

BMI = body mass index, LGWR = laparoscopic gastric wedge resection, SBD = sentinel basin dissection, LGSR = laparoscopic gastric segmental resection, AJCC = American Joint Committee on Cancer
Values are presented as mean ± standard deviation, median [min–max] or number of patients (percentage)
^*Time from the first injection of tracer to the identification of the frozen biopsy result for the sentinel lymph node
^†Due to the identification of metastatic sentinel lymph node on frozen biopsy examination
