Short-Term Outcomes of Conventional Laparoscopic versus Robot-Assisted Distal Pancreatectomy for Malignancy: Evidence from US National Inpatient Sample, 2005–2018.

Simple Summary: This study investigated the short-term outcomes of laparoscopic versus robot-assisted distal pancreatectomy for pancreatic cancer using the US Nationwide Inpatient Sample (NIS) database from 2005 to 2018. Data from 886 patients were analyzed. Despite higher costs, robot-assisted surgery was associated with fewer complications, reduced risk of blood transfusion, and a shorter hospital stay compared to conventional laparoscopy. The findings suggest that while robot-assisted surgery comes with increased expenses, it may offer better short-term outcomes for patients with pancreatic cancer. Background: The primary treatment for pancreatic cancer is surgical resection, and laparoscopic resection offers benefits over open surgery. This study aimed to compare the short-term outcomes of robot-assisted vs. conventional laparoscopic distal pancreatectomy. Methods: Data of adults ≥ 20 years old with pancreatic cancer who underwent conventional laparoscopic or robot-assisted laparoscopic distal pancreatectomy were extracted from the United States (US) Nationwide Inpatient Sample (NIS) 2005–2018 database. Comorbidities and complications were identified through the International Classification of Diseases (ICD) codes. Short-term outcomes were compared using logistic regression and included length of hospital stay (LOS), perioperative complications, in-hospital mortality, unfavorable discharge, and total hospital costs. Results: A total of 886 patients were included; 27% received robot-assisted, and 73% received conventional laparoscopic surgery. The mean age of all patients was 65.3 years, and 52% were females. Multivariable analysis revealed that robot-assisted surgery was associated with a significantly reduced risk of perioperative complications (adjusted odds ratio (aOR) = 0.61, 95% confidence interval (CI): 0.45–0.83) compared to conventional laparoscopic surgery. Specifically, robot-assisted surgery was associated with a significantly decreased risk of VTE (aOR = 0.35, 95% CI: 0.14–0.83) and postoperative blood transfusion (aOR = 0.37, 95% CI: 0.23–0.61). Robot-assisted surgery was associated with a significantly shorter LOS (0.76 days shorter, 95% CI: −1.43–−0.09) but greater total hospital costs (18,284 USD greater, 95% CI: 4369.03–32,200.70) than conventional laparoscopic surgery. Conclusions: Despite the higher costs, robot-assisted distal pancreatectomy is associated with decreased risk of complications and shorter hospital stays than conventional laparoscopic distal pancreatectomy.
