Abstract

Objective: To evaluate the influence of internal drainage on status of nutritional markers in patients with obstructive jaundice.Dessing: Prospective longitudinal study.Setting: University hospital, Spain.Subjects: 39 patients with obstructive jaundice (18 benign and 21 malignant obstructions).Interventions: Nutritional state was assessed before and 10 days after endoscopic drainage.Main outcome measures: One anthropometric (body weight < 95% of ideal) and two biochemical (albumin <35 g/L and prealbumin <170 mg/L) as an indication of protein calorie malnutrition. Retinol binding protein and transferrin concentrations, total lymphocyte count, and nutritional prognostic index (NPI) were also measured.Results: Thirty patients (77%) had protein calorie malnutrition. After internal drainage, 6 patients with benign obstruction and 11 with malignant tumours remained malnourished. No anthropometric variables or concentrations of proteins with long half-lives were affected by drainage. However, prealbumin (p < 0.01) and transferrin (p < 0.01) concentrations, and total lymphocyte count (p < 0.001) increased significantly in both groups. NPI also improved significantly after drainage from 43 (9) compared with 37 (5) in benign obstructions (p < 0.05) and 58.7 (14) compared with 52 (12) in malignant (p < 0.05), although in the latter group the mean nutritional risk index remained high.Conclusions: Concentrations of some of the visceral proteins studied (prealbumin and transferrin) improved 10 days after internal biliary drainage for both benign and malignant obstruction. However, many patients with malignant tumours remained malnourished with a high nutritional risk index.
