<jats:title>Background</jats:title>
<jats:p>The benefits of robotic over laparoscopic surgery for Roux-en-Y gastric bypass (RYGB) are debatable, with current evidence suggesting no significant differences in short-term outcomes. This study compares short-term outcomes and excess weight loss (EWL) % difference between these two techniques.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>A retrospective study of patients undergoing RYGB between January 2016 and November 2020 at a single centre. Demographic, peri-operative and EWL% data were analysed.</jats:p>

<jats:title>Results</jats:title>
<jats:p>424 RYGB procedures were performed by three surgeons including 77 robotic (RRYGB) and 347 laparoscopic (LRYGB) operations. The first 8 RRYGB were excluded being early in the learning curve and the operative technique was modified afterwards. There were no statistically significant demographic differences. The median operative time was 179 (151 – 195) and 149 (123 -171) minutes in the RRYGB and LRYGB groups respectively (P &lt; 0.001). There were no statistically significant differences between both groups in complications, length of stay, 30-day readmission and EWL% at 6 and 12 months. The EWL% at 2 years was 88.5 (+/-19.1) and 66.6 (+/-29.8) in the RRYGB and LRYGB groups respectively (P = 0.003).</jats:p>

<jats:title>Conclusions</jats:title>
<jats:p>RRYGB increases the operative time with no significant short-term outcome differences. The EWL% was higher at 2 years, probably due to a narrower hand-sewn gastro-jejunal anastomosis.</jats:p>
