Outcome Measures

Primary Outcomes (2)

  • Number of Participants with Chylous Effusion (Сhilo-/lymphorrhea)

    This outcome will be determined by assessing the milky of the drainage discharge, and comparing the content of triglycerides, glucose, cholesterol and lactate dehydrogenase (LDH) in the drainage discharge with those in the blood plasma

    within 10 days of starting a regular diet after surgery

  • Number of Participants with Lymphocele

    retroperitoneal liquid formation ≥5 cm in diameter according to ultrasound after drainage removal

    10 days after the surgery in patient who starting a regular diet after drainage removal

Secondary Outcomes (18)

  • The amount of drainage discharge 1

    24 hours after the surgery

  • The amount of drainage discharge 2

    48 hours after the surgery

  • The amount of drainage discharge 3

    72 hours after the surgery

  • Concentration of triglycerides in the drainage discharge

    72 hours after the surgery

  • Concentration of triglycerides in blood plasma

    72 hours after the surgery

  • +13 more secondary outcomes
