The effect of learning curve on perioperative outcomes of robotic gastrectomy in two western high‐volume centers

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. Re...

Description
Summary: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.
