Rationale: Patients with short bowel syndrome (SBS) are at high risk of malnutrition due to the inherent physiological consequences of the condition.

 

Objectives

Evaluate malnutrition and sarcopenia prevalence in SBS outpatients.

Analyze agreement between emerging (BIA, muscle ultrasound) and traditional methods for body composition and functionality.

Methods: Observational study of SBS patients in a clinically stable population undergoing nutritional monitoring in a nutrition clinic. Data: demographics, BIA, ultrasound, anthropometry, handgrip strength and TUG. GLIM and EWGSOP2 criteria defined malnutrition and sarcopenia. Statistics: SPSS v31.0; results as median [IQR] and %. Mann–Whitney U, Fisher’s, and Spearman’s tests were used.

Results: 25 patients (68% female; median 70 [52.5–73.5] years). Malnutrition: 72% (n=18; 7 severe), mainly due to low BMI and muscle mass; weight loss was rare. Sarcopenia: 8% (n=2), both with SBS of malignant etiology (Table 1). No differences found by parenteral nutrition requirement or etiology (benign vs. malignant). Muscle ultrasound strongly correlated with BIA (Area–ASMMI: r=0.795; Y-axis–ASMMI: r=0.851; p<0.001). Handgrip strength correlated stronger with emerging techniques [Muscle Area (r=0.774), Phase Angle (r=0.771), ASMMI (r=0.707)] than with calf circumference (r=0.507); muscle area inversely correlated with functionality (TUG).

Conclusion: Malnutrition is highly prevalent in SBS outpatients and is mainly characterized by altered muscle mass and low BMI rather than weight loss or functional decline in our sample.

Sarcopenia occurred only in malignant cases, though the small sample size limits the interpretation of this finding.

BIA and muscle ultrasound show high concordance and a clear association with handgrip strength and functionality, supporting their utility as complementary tools in the nutritional assessment of SBS patients.
