ABSTRACT
INTRODUCTION:
A robotic laparoendoscopic single-site access surgery (R-LESS) platform that incorporates the EndoWrist function of robotic instruments may provide better triangulation and retraction during LESS. The aim of the study is to assess if R-LESS is feasible with standard robotic instruments via a single incision and whether the approach could reduce the difficulty of the procedure and confer additional benefits over conventional LESS.METHODS:
This was a prospective randomized controlled study investigating the workload performance, efficacy, and risks of performing R-LESS when compared with human LESS (H-LESS) in a survival porcine model for cholecystectomy and gastrojejunostomy. The primary outcome is the NASA task load index. Secondary outcomes included the difficulty of the procedures, procedural time, morbidities, and mortalities.RESULTS:
Twenty-four cholecystectomies and gastrojejunostomies using the R-LESS or H-LESS approach (1212) were performed. None of the swine suffered from procedural adverse events and none of the procedures required conversion. In both the cholecystectomy and gastrojejunostomy groups, R-LESS was associated with significantly lower NASA task load index (P < 0.001) and reduced difficulties in various steps of the procedures. No differences in the overall procedure times of the two procedures were observed (P = 0.315).CONCLUSION:
The R-LESS approach significantly reduced the workload and difficulties of LESS cholecystectomies and gastrojejunostomies. A dedicated single-site platform that could reduce instrument clashing while retaining the EndoWrist function is eagerly awaited.Palabras clave
