    Summary
    This summary is machine-generated.

    General surgeons can master arterial anastomosis techniques with practice. After initial training, surgical time decreased significantly, maintaining a 100% patency rate in rat abdominal aorta repairs.

    Area of Science:

    • Vascular Surgery
    • Microsurgery Techniques
    • Surgical Education

    Background:

    • Mastering microsurgical anastomosis is crucial for vascular repair.
    • Objective data on the learning curve for specific arterial diameters is limited.

    Purpose of the Study:

    • To determine the time and number of procedures required for a general surgeon to achieve proficiency in arterial anastomosis.
    • To evaluate the impact of practice on anastomosis quality and operative time.

    Main Methods:

    • A general surgeon practiced arterial anastomosis on rat abdominal aortas (1.25-1.5 mm diameter) using a microscope.
    • Probes were used for lumen calibration, and procedures were performed over 35 laboratory hours.
    • Forty procedures were conducted, with animals surviving 1-6 weeks post-operation.

    Main Results:

    • An initial 15-hour familiarization period with equipment was necessary.
    • Following practice, operative time decreased from 45 to 15 minutes per procedure.
    • A 100% vessel patency rate was achieved in all 40 anastomoses.

    Conclusions:

    • General surgeons can achieve technical proficiency in small-diameter arterial anastomosis through dedicated practice.
    • The learning curve involves an initial adaptation period followed by significant time reduction.
    • Microsurgical skills in vascular anastomosis can be effectively acquired and maintained.
