Connecting the Macro- and Micro-Scale Properties in Human Solid Tumors: Hydraulic Conductivity

reported to be a potentially safe and feasible procedure for early gastric cancer (EGC), there is currently no study demonstrating the feasibility of SIDG for advanced gastric cancer (AGC) alone.Materials and Methods: Database of patients clinically diagnosed as AGC who underwent SIDG from November 2017 to April 2022 was retrospectively analyzed.Those who had distant metastasis, and those who underwent palliative surgery were excluded.Patient demographics, operation data, and postoperative complications were reviewed.Results: A total of 117 patients were included for the final analysis.Among them, 74 (63.2%) were male, and mean age was 63.9 ± 11.9 years.Average body mass index was 24.2 ± 2.9 kg/m2.The number of patients with stage pT2, pT3, pT4a and pT4b after surgery was 34 (29.1%),47 (40.2%), 34 (29.1%) and 2 (1.7%) respectively.Mean operation time was 170.3 ± 65.0 mins.and average estimated blood loss was 30.8 ± 63.0 ml.Average number of retrieved lymph nodes was 59.3 ± 22.1.Patients started their first soft fluid diet on an average of 2.3 ± 1.0 postoperative days, and first flatus was observed after 3.1 ± 1.3 postoperative days.Overall mean hospital stay was 6.9 ± 2.9 days.Early complications (within 30 days) greater than Clavien-Dindo grade III were found in 5 patients (4.3%) and late complications (after 30 days) were found in 4 patients (3.4%).Conclusions: This study shows that SIDG is feasible in some selected patients with AGC.
