Overview

Retrospective cohort study reveals abnormal bioelectrical impedance predicts severe complications in hepatopancreaticobiliary surgery, indicating the need for targeted nutritional assessment.

Key Points

  • To determine whether preoperative bioelectrical impedance analysis detects clinically meaningful body composition alterations and predicts severe complications following major hepatopancreaticobiliary surgery.
  • Conducted a single-center retrospective observational cohort study of 73 patients undergoing major hepatopancreaticobiliary surgery.
  • Measured preoperative bioelectrical impedance variables—resistance, reactance, phase angle, fat-free mass index, fat mass index, and Body Composition Chart status—and compared them with healthy reference standards.
  • Assessed severe postoperative complications using the Clavien–Dindo classification and identified predictors using multivariable Firth penalized logistic regression.
  • Reactance and phase angle were significantly reduced across all sex and BMI strata (all p < 0.05), with patients exhibiting a median phase angle of 4.3° compared to healthy controls (p < 0.001).
  • Body Composition Chart classification outside the reference range independently predicted severe postoperative complications (OR 3.32, 95% CI 1.04–12.87, p = 0.043).
  • Higher Eastern Cooperative Oncology Group performance status was also independently associated with severe postoperative complications (OR 2.07, 95% CI 1.08–4.24, p = 0.028).
