Outcome Measures

Primary Outcomes (3)

  • The AGI score

    The AGI score of the patient within the 7th postoperative day was performed according to the European Society of critical care (2012) guidelines for AGI.

    1 month

  • Intra-abdominal pressure (IAP)

    We defined it as the maximum value of intra-abdominal pressure within 7 days after surgery

    1 month

  • Characteristics of gut microbiomes

    Feces are collected with sterilized 2 ml tubes and frozen at -80 °C until DNA extraction, preparing for microbe analysis

    1 month

Secondary Outcomes (13)

  • Return time of bowel sounds

    1 month

  • Number of bowel sounds

    1 month

  • First defecation time

    1 month

  • Bristol Stool Form Scale score

    1 month

  • Proportion of cocci and bacilli in feces

    1 month

  • +8 more secondary outcomes
