Background : An increasing number of pancreaticoduodenectomies (PPPD) have been performed with the Xi system. The advent of the SP system has recently allowed more minimally invasive surgery for patients with reduced ports. Since SP PPPD is a novel technique, we aim to investigate SP PPPD compared to previous Xi PPPD.
Methods : The records of patients who underwent robotic pancreaticoduodenectomy using the Xi/Si and SP systems between May 2021 and September 2023 at a single center were retrospectively reviewed. The resection phase was performed with the laparoscopic method and the reconstruction with the robotic systems. Conversion surgeries to open surgeries were excluded.
Results : Of the 51 patients, 37 underwent the reconstruction with the Da Vinci Xi/Si system and 14 with the SP system. BMI of the patients in the SP group was significantly lower than that of the Xi group (Xi 26.2±6.6 vs. SP 22.5±2.3, P=0.05). Both groups did not differ in the operative time (Xi 470.9±77.2 vs. SP 444.3±59.5, P=0.250) and estimated blood loss (Xi 469±5 vs. SP 357.9±240.1, P=0.152). In the analysis of the malignant cases (Total N=33), there was no difference in R0 resection rate (Xi 90.5% vs. SP 100%) in both groups. The Xi/Si group had a significantly higher postoperative complication rate than the SP group (51.4% vs. 14.3%, P=0.016). However, the Clavien-Dindo grade greater than 3a showed no difference (P=0.184).
Conclusions : This was the first study to introduce the SP PPPD. The SP PPPD was safe and feasible compared to the Xi/Si system according to the short-term outcome.
