Abstract
Background
The robotic approach has vast applications in surgery; however, the utility of robotic gastrectomy has yet to be clearly defined. This study aimed to compare outcomes following robotic gastrectomy at our institution to the national patient-specific predicted outcomes data provided by the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP).
Methods
We prospectively studied 73 patients who underwent robotic gastrectomy under our care. ACS NSQIP outcomes after gastrectomy and predicted outcomes for our patients were compared with our actual outcomes utilizing students t test and chi-square analysis, where applicable. Data are presented as median (mean ± SD).
Results
Patients were 65 (66 ± 10.7) years old with a BMI of 26 (28 ± 6.5) kg/m2. 35 patients had gastric adenocarcinomas and 22 had gastrointestinal stromal tumors Operative duration was 245 (250 ± 114.7) minutes, estimated blood loss was 50 (83 ± 91.6) mL, and there were no conversions to ‘open’. 1% of patients experienced superficial surgical site infections compared to the NSQIP predicted rate of 10% (P < .05). Length of stay (LOS) was 5 (6 ± 4.2) days vs NSQIP’s predicted LOS of 8 (8 ± 3.2) days (P < .05). Three patients died during their postoperative hospital course (4%), due to multi-system organ failure and cardiac arrest. 1-year, 3-year, and 5-year estimated survival for patients with gastric adenocarcinoma was 76%, 63%, and 63%, respectively.
Discussion
Robotic gastrectomy yields salutary patient outcomes and optimal survival for varying gastric diseases, particularly gastric adenocarcinoma. Our patients experienced shorter hospital stays and reduced complications relative to patients in NSQIP and predicted outcome for our patients. Gastrectomy undertaken robotically is the future of gastric resection.
