BACKGROUND: Serious nutritional complications after Roux-en-Y gastric bypass (RYGBP) are infrequent. In a retrospective study of patients operated during a 68-month period, malnutrition was investigated to analyze circumstances associated with nutritional failure. METHODS: In 236 consecutive RYGBPs, 11 patients with severe malnutrition were identified (4.7%) with age 45.1 +/- 10.6 years (10 females/1 male) and initial BMI 54.6 +/- 8.4 kg/m(2). RESULTS: In these 11 patients, the derangement was diagnosed 17.9 +/- 15.8 months after RYGBP, following defined events in 63.6% (gastric stenosis, associated diseases ) or mostly exaggeration of expected symptoms in 36.4% (vomiting without endoscopic abnormalities). BMI then was 31.4 +/- 8.6 kg/m(2) (42.5 +/- 9.9% total reduction, or 2.4 +/- 2.1% decrease/month), and serum albumin and hemoglobin were 24.0 +/- 8.2 g/L and 97.0 +/- 23.0 g/L respectively. Edema was present in 45.4% (5/11), hospitalization was required in 54.5% (6/11), and 18.2% (2/11) eventually died. CONCLUSIONS: Serious malnutrition was unusual but not exceedingly rare in this series. Exogenous precipitating factors were clearly identified in 63.6% of the patients. Careful clinical and nutritional follow-up is recommended to prevent these uncommon but potentially dangerous complications.
