Summary
This study objectively quantifies robotic proctectomy (RP) workflow by correlating surgical steps with console time (CT) and total operative time (TOT). Key steps like splenic flexure mobilization significantly impact operative times, offering insights for surgical efficiency.
Area of Science:
- Surgical Workflow Analysis
- Robotic Surgery
- Procedure Optimization
Background:
- Surgical workflow assessments provide critical insights into procedure variability, complexity, and surgeon proficiency.
- Objective evaluation of surgical steps and transitions is essential for optimizing robotic proctectomy (RP).
Approach:
- Annotated 31 robotic proctectomies using a procedure-specific card.
- Employed Spearman's correlation to assess the association between step time, step visit frequency, console time (CT), and total operative time (TOT).
Key Points:
- Mean of 49.0 steps per RP; mean CT of 213 minutes and TOT of 283 minutes.
- Posterior mesorectal dissection and anastomosis required the most visits and time, respectively.
- Strong correlations identified between CT/TOT and specific steps like IMV ligation, splenic flexure mobilization, and rectal dissection.
Conclusions:
- Standardized annotation objectively quantifies surgical steps and their correlation with CT and TOT in RP.
- This methodology offers a data-driven approach to understanding and improving robotic surgical workflow.
