    The study compared ileotransverse colon Overlap and π-shaped anastomosis in laparoscopic right hemicolectomy for right colon cancer.

  • 2

    Overlap anastomosis resulted in shorter operative time, milder postoperative inflammation, and faster gastrointestinal recovery compared to π-shaped anastomosis.

  • 3

    No significant differences in clinical anastomotic leakage rates were observed between the Overlap and π-shaped groups.

  • 4

    The study was a prospective randomized controlled trial involving 120 patients, with 60 assigned to each anastomosis technique.

  • 5

    Overlap anastomosis is recommended for short-term recovery benefits, but its superiority in reducing leakage remains inconclusive due to sample size limitations.
