RESUMEN
BACKGROUND: the development of specialised nutritional support techniques allows the maintenance of an adequate supply of nutrients in those patients in whom oral feeding is not possible or is insufficient in relation to their requirements, trying to improve the quality of life, especially in those with chronic diseases. METHODS: single-center clinical study carried out in a clinical-nutritional center consisting of a medically supervised nasogastric-duodenal tube feeding treatment for overweight, obesity and increased body fat percentage in patients requiring it by means of duodeno-enteral feeding, expecting losses of more than 10 %. RESULTS: twenty-nine patients completed the protocol (20.4 % male and 79.6 % female) with a mean age of 38 years (SD: 12.4); 87.2 kg (SD: 18.5) mean weight; 37.9 kg (SD: 4.8) mean iFat%; 32.4 (SD: 5.4) iMean body mass index (BMI); 100 cm (SD: 16.0) iMean waist; 113.6 cm (SD: 10.4) iMean hip; 33.8 cm (SD: 3.9) iMean upper arm circumference; 65.5 cm (SD: 7.5) iMean thigh circumference; 9.7 (SD: 4.8) iVisceral fat index; and 22.9 days (SD: 13.9) mean treatment. A mean of 22.9 (SD: 13.9) days of MESUDEFT influences weight loss, fat loss, visceral fat loss and decreased arm, hip and thigh circumferences (p < 0.05) (i: initial). CONCLUSIONS: MESUDEFT is shown to be an effective alternative as a sole treatment or as an adjunct prior to bariatric surgery for obesity or overweight treatment with a minimum of 10 % loss of BMI and fat mass at completion and 3-6 months follow-up.
