Nutritional status after total and partial gastrectomy with Roux-en-Y reconstruction.

Dietary intake and nutritional status were studied in two groups of patients after total gastrectomy (n = 10) and after partial gastrectomy (n = 10). All patients were reconstructed with a Roux-en-Y loop. Investigations were carried out 4-17 years after the operation. Eight patients in the group undergoing total gastrectomy and four patients undergoing partial gastrectomy had gastric carcinoma and were without recurrent disease 5-15 years after the operation. A clinical dietician conducted an anthropometric evaluation. All patients underwent an upper gastrointestinal endoscopy, clinical examination, [14C]triolein breath test and a blood chemistry profile. The median weight loss from operation to investigation was 2.1 kg in the partial gastrectomy group and 6.7 kg in the total gastrectomy group (n.s.). After partial gastrectomy three patients had a subnormal body mass index (n.s.). This was not found in the total gastrectomy group. Energy intake was below that recommended in seven patients in the partial gastrectomy group (three of them had a subnormal body mass index) and in two in the total gastrectomy group (n.s.) [14C]triolein breath testing revealed fat malabsorption in three patients after partial gastrectomy and in five patients after total gastrectomy (n.s.).
