    The study developed a predictive nomogram model for postoperative hypoxemia following laparoscopic sleeve gastrectomy in obese patients.

  • 2

    Postoperative hypoxemia is a common complication after bariatric surgery, with an incidence rate reported as high as 80% in obese patients.

  • 3

    Data from 195 patients who underwent laparoscopic sleeve gastrectomy were analyzed, with an external validation cohort of 105 patients included.

  • 4

    Key predictive variables for the model were selected based on literature, expert consultation, and clinical experience.

  • 5

    The model aims to enhance surgical safety by identifying high-risk patients early, facilitating timely preventive measures.
