Introduction: To compare outcomes of robotic gastrectomy (RG) performed during the learning curve (P1) with those after its completion (P2). Methods: In this retrospective study, all consecutive RG patients (n = 92) performed between 2008 and 2018 were included. Primary outcome was conversion rate. Results: D2 lymphadenectomies were more common in P2 (41, 97.6%) than P1 (41, 82.0%) (p = 0.019). Conversions were 11 (22%) in P1 versus 2 (4.8%) in P2 (p = 0.006). Postoperative morbidity was comparable between the groups. Median hospital stay was significantly shorter in P2. The only factor significantly associated with conversion was P2 (odds ratio = 0.18; 95% confidence interval, 0.04–0.85; p = 0.039). The 5-year overall survival in P1 was 79.6% versus 79.7% in P2 (p = 0.373). Conclusions: The learning curve affected operative and postoperative outcomes: during the learning curve, conversion to open surgery was significantly more frequent, the number of D2 was higher and patients were discharged earlier.

Abstract
Introduction: To compare outcomes of robotic gastrectomy (RG) performed during the learning curve (P1) with those after its completion (P2). Methods: In this retrospective study, all consecutive RG patients (n = 92) performed between 2008 and 2018 were included. Primary outcome was conversion rate. Results: D2 lymphadenectomies were more common in P2 (41, 97.6%) than P1 (41, 82.0%) (p = 0.019). Conversions were 11 (22%) in P1 versus 2 (4.8%) in P2 (p = 0.006). Postoperative morbidity was comparable between the groups. Median hospital stay was significantly shorter in P2. The only factor significantly associated with conversion was P2 (odds ratio = 0.18; 95% confidence interval, 0.04–0.85; p = 0.039). The 5-year overall survival in P1 was 79.6% versus 79.7% in P2 (p = 0.373). Conclusions: The learning curve affected operative and postoperative outcomes: during the learning curve, conversion to open surgery was significantly more frequent, the number of D2 was higher and patients were discharged earlier.
