Apolipoproteins A-I and B as predictors of complications in gallbladder lithiasis surgical patients.

Specific serum proteins have been traditionally used in the assessment of protein-energy malnutrition. Some short half-life serum proteins have been related to the appearance of postoperative complications in surgical patients with low-risk pathologies that, far from undernutrition, showed a trend toward overweight and obesity. Apolipoproteins have been proposed as potential tools to assess protein status and nutritional recovery, so we investigated apolipoproteins A-I and B as new tools with prognostic value to detect postoperative complications.
