Introduction:
Laparoscopic gastrectomy (LG) is a complicated procedure with a long learning curve. This study was performed to investigate the usefulness of our stepwise training program for LG for improving the quality of the surgery.
Methods:
The stepwise training method comprised the following four steps: (1) basic training using a dry box and checking by mentors; (2) advanced training, including the use of animals and cadavers; (3) clinical experience, including standardization and preoperative three-dimensional simulation; and (4) self-assessment and feedback. In total, 153 patients who underwent curative gastrectomy for gastric cancer were included in this study.
Results:
The operative time gradually decreased for both laparoscopic distal gastrectomy (LDG) (2013, 395 minutes; 2017, 278 minutes; P < .001; ρ = -0.68) and laparoscopic total gastrectomy (LTG) (2013, 476 minutes; 2017, 319 minutes; P < .001; ρ = -0.56). The blood loss volume gradually decreased for both LDG (2013, 43.0 mL; 2017, 18.6 mL; P < .005; ρ = -0.30) and LTG (2013, 143.8 mL; 2017, 13.5 mL; P < .005; ρ = -0.41).
Conclusions:
Our stepwise training program contributes to reduce operation time and blood loss in LG.
