Pancreaticoduodenectomy with right gastric vessels preservation: impact on intraoperative and postoperative outcomes

BackgroundSympathetic denervation of the antropyloric area combined with relative devascularization from division of the right gastric vessels (RGV) during pancreaticoduodenectomy (PD) could predispose to delayed gastric emptying (DGE). Therefore, some authors advocated for RGV preservation (RGVP), where feasibility and utility for the prevention of post-operative DGE have never been investigated. MethodsFrom 2011 to 2014, patients who underwent classic Whipple PD (CWPD, n=34), standard pylorus-preserving PD (PPPD, n=44) or PPPD with RGVP (n=22) were retrospectively analysed. ResultsRGVP was not possible in 12% of the cases because of an intraoperative injury of the RGV. There was no difference between CWPD, standard PPPD and PPPD with RGVP in terms of intraoperative blood loss, operative time, number of lymph node harvested and resection margins. Post-operative morbidity and mortality were comparable between the three groups, including rate (27%, 34% and 32%, P=0.77) and severity of DGE, delay in removing nasogastric tube and use of prokinetics. Hospital stay was similar in all the compared groups. ConclusionThis is the first study comparing post-operative outcomes after PPPD with RGVP, standard PPPD and CWPD. Although feasible and safe, RGVP during PPPD appeared to offer no obvious clinical benefit in terms of preventing post-operative complications, especially DGE.
