Short‐term surgical outcomes of open, laparoscopic, and robot‐assisted pancreatoduodenectomy: A comparative, single‐center, retrospective study

Abstract Purpose Although laparoscopic pancreaticoduodenectomy (LPD) and robot‐assisted pancreaticoduodenectomy (RPD) are gradually gaining popularity, their advantages over open pancreaticoduodenectomy (OPD) remain controversial. This study aimed to compare the short‐term outcomes of OPD, LPD, and RPD to elucidate the advantages and disadvantages of each procedure. Methods We retrospectively analyzed 16 LPD, 43 RPD, and 36 OPD procedures performed at a single center between April 2020 and May 2024. Clinical data, including operative time, estimated blood loss, postoperative complications, length of hospital stay, and hospitalization costs, were retrospectively collected and analyzed. Results RPD demonstrated a significantly longer operative time (553 min) than OPD (446 min) and LPD (453 min) but a significantly lower estimated blood loss than OPD (150 mL vs. 400 mL, p < .001). Postoperative complication rates (Clavien–Dindo grade ≥3) were lower for RPD (24.4%) than those for OPD (50.0%) and LPD (68.8%). RPD also showed a significantly lower rate of clinically relevant postoperative pancreatic fistula (14.6% vs. 38.9% for OPD and 43.8% for LPD) and a shorter duration of hospitalization (11 vs. 28 days for OPD and 21 days for LPD, p < .001). Hospitalization costs were higher for RPD (20 109 USD) than for OPD (18 487 USD, p < .001), with LPD (20 496 USD) and RPD costs being similar. Conclusions RPD appears to offer advantages in terms of reduced blood loss and postoperative complications and shortened hospital stay despite longer operative times and higher hospitalization costs. Therefore, RPD may be a more beneficial approach than OPD or LPD in pancreatic surgery.
