Fusion Surgery-Driven Robotic Right Colectomy With Intracorporeal Functional End-to-End Anastomosis Using the...

Area of Science:

• Minimally invasive surgery
• Surgical oncology
• Robotic surgery

Background:

• Intracorporeal anastomosis (IA) improves recovery in right colectomy but intracorporeal functional end-to-end anastomosis (FEEA) is challenging.
• A novel fusion surgery workflow was developed integrating double-bipolar method (DBM), powered stapling, and indocyanine green (ICG)-guided perfusion assessment.

Purpose of the Study:

• To evaluate the feasibility, safety, and workflow adherence of a standardized fusion surgery for robotic right colectomy with intracorporeal FEEA.
• To assess the impact of the standardized workflow on operative metrics and postoperative recovery.

Main Methods:

• Single-center retrospective study of 35 consecutive patients undergoing robotic right colectomy with intracorporeal FEEA using DBM.
• Primary outcomes: feasibility, descriptive safety, workflow adherence. Secondary outcomes: operative metrics, postoperative recovery.

Main Results:

• All 35 procedures were successfully completed robotically without conversion or workflow deviation.
• No anastomotic leaks or reoperations occurred. Postoperative complications were low (2.9% for ileus, SSI, and major complications).
• Median operative time was 221 minutes, median console time was 146 minutes, and median hospital stay was 6 days.

Conclusions:

• The structured fusion surgery workflow for robotic right colectomy with intracorporeal FEEA is feasible and descriptively safe.
• This standardized workflow, integrating DBM, powered stapling, and perfusion assessment, may enhance intracorporeal reconstruction stability.
• Further prospective validation is warranted to confirm these findings in experienced robotic settings.
