Delayed gastric emptying after pylorus‐preserving pancreatoduodenectomy: Comparison between traditional open surgery and full‐robotic approach with da Vinci Xi

Abstract

INTRODUCTION: Delayed gastric emptying (DGE) is a frequent complication after pancreatoduodenectomy, especially after pylorus preservation (Pp). We evaluated the effect of a fully robotic approach with da Vinci Xi on DGE after PpPD. METHODS: Open and robotic PDs were performed in 353 and 50 cases, respectively, from January 2009 to March 2022. We compared the clinical outcomes and incidence of clinically relevant DGE between robotic PpPD (R-PpPD) and open PpPD after one-to-one case-control matching. RESULTS: Each group consisted of 30 patients. Clinically relevant DGE was less common after R-PpPD (3/30 [10%] vs. 10/30 cases [33.3%], p = 0.028). The median length of hospital stay (LoS) was significantly lower in the R-PpPD group (10 vs. 15 days, p = 0.013). CONCLUSION: The reduced tissue trauma by the minimally invasive robotic approach is associated with a lower incidence of DGE, reducing the LoS and encouraging PpPD performed using the fully robotic approach.
