The learning curve for single-port robot (SPR) colectomy was achieved by the 18th case. This study analyzed the learning curve and initial complications of SPR platform use in colorectal cancer surgery.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics
  • Colorectal Surgery

Background:

  • Robotic surgery is increasingly adopted for colorectal cancer.
  • Single-port robot (SPR) platforms offer a newer approach.
  • Assessing the learning curve and early outcomes is crucial for SPR adoption.

Purpose of the Study:

  • To analyze the learning curve for single-port robot (SPR) colectomy.
  • To evaluate initial complications associated with SPR platform use in colorectal cancer surgery.
  • To establish benchmarks for surgeon proficiency with SPR technology.

Main Methods:

  • Retrospective review of 39 patients undergoing SPR colectomy.
  • Cumulative sum methodology used to assess the learning curve.

  • Patient data analyzed across three phases of surgical cases.

    • Main Results:

    • Surgeon console time significantly improved across surgical phases (P<0.001).
    • The learning curve for SPR colectomy was estimated to be around 18 cases.
    • Eight patients experienced complications, including ileus, hemoglobin changes, urinary retention, and fluid collection.

    Conclusions:

    • The learning curve for single-port robot colectomy can be achieved efficiently.
    • SPR platform adoption in colorectal surgery demonstrates a manageable learning curve.
    • Further research can optimize SPR utilization and patient outcomes.
