This summary is machine-generated.

Robotic gastrectomy (RG) has higher upfront costs but similar total perioperative expenses compared to open gastrectomy (OG) due to reduced hospital stay. RG shows a 76.5% probability of lowering overall costs.

Area of Science:

  • Surgical Oncology
  • Health Economics
  • Minimally Invasive Surgery

Background:

  • Robotic surgery platforms incur significant implementation and maintenance costs.
  • The overall perioperative cost-effectiveness of robotic gastrectomy (RG) versus open gastrectomy (OG) remains unclear.

Purpose of the Study:

  • To determine the perioperative cost magnitude associated with robotic gastrectomy (RG).
  • To compare the total costs of RG and conventional open gastrectomy (OG).

Main Methods:

  • Retrospective analysis of 119 patients undergoing major gastrectomy (February 2018-December 2021).
  • Calculation and comparison of perioperative costs (intraoperative, 30-day inpatient/outpatient) for RG and OG.
  • Bayesian framework used to estimate the likelihood of cost reduction with RG.

Main Results:

  • Postoperative complication rates were similar between RG (10%) and OG (13%).
  • Robotic gastrectomy (RG) resulted in a shorter median hospital stay (4 vs. 7 days).
  • Despite higher intraoperative costs for RG, total perioperative cost ratios were similar (RG: 6.1 vs. OG: 6.4), driven by lower postoperative hospitalization costs for RG.

Conclusions:

  • Robotic gastrectomy (RG) demonstrates similar total perioperative costs to open gastrectomy (OG).
  • Reduced postoperative hospitalization costs offset the higher intraoperative expenses of RG.
  • RG has a 76.5% probability of reducing overall perioperative costs.
