Robotic versus Laparoscopic Emergency and Acute Care Surgery: Redefining Novelty (RLEARN): feasibility and benefit of robotic cholecystectomy for acute cholecystitis at a level 1 trauma center.

Background: This study aims to compare outcomes of robotic cholecystectomy (RC) versus laparoscopic cholecystectomy (LC) in the setting of a level 1 trauma center.

Methods: We performed a retrospective study of our hospital data (2021-2024) on patients who underwent LC or RC. Using a previously validated intraoperative grading system, four grades of cholecystitis were defined as mild (A), moderate (B), severe (C), and extreme (D). Outcomes were operative times and rates of conversion to open surgery.

Results: In total, 260 patients (n=130 RC and n=130 LC) were included. Patients were primarily female (69.2%), with mean age of 47±18.3 years. The majority of cases had grade B cholecystitis (41.2%). Patients undergoing RC had lower operative times compared with LC in grade B (101.87±17.54 vs 114.96±29.44 min, p=0.003) and grade C (134.68±26.97 vs 152.06±31.3 min, p=0.038). Conversion rate to open cholecystectomy were similar in both groups (p=0.19).

Conclusion: RC had similar results as LC in terms of operative time and in fact has significantly lower operative time in patients with grade B and grade C cholecystitis.

Level of evidence: Level III-retrospective study.
