title: [Evolution of the blood parameters after morbid obesity surgery with the duodenal crossing technique].
abstract: OBJECTIVE
  To assess the course of blood parameters from patients with morbid obesity submitted to the duodenal crossing surgical technique.
  
  
  METHODS
  110 patients were studied in whom post-surgical monitoring of ponderal and laboratory parameters (the ones most influenced by this type of surgery such as hematocrit, hemoglobin, glucose, total proteins, albumin, calcium, PTH, ALT, Quick's index, total bilirubin, cholesterol and triglycerides, iron, ferritin, folic acid, and vitamin B12) has been carried out. Postsurgical monitoring has been carried out at months 3, 6, 12,18, 24, 36, 48, and 60. The shortest followup time has been one year.
  
  
  RESULTS
  Weight loss is higher than 50% of the weight in excess and is maintained throughout the study, comprising more than 75% of the patients. During the postsurgical follow-up, there is a clear iron deficiency concurrent with the presence of anemia, as well as an evident increase in PTH. Normalization of glycemia, cholesterol, and triglyceride levels reaches almost 100%.
  
  
  CONCLUSIONS
  changes in blood parameters presented by patients with morbid obesity submitted to the duodenal crossing technique, indicators of nutritional complications, affect about 10% of the patients (with the exception of iron deficiency and PTH impairment), and most of them are easily corrected with pharmacological and nutritional supplements, the body getting adapted to these deficits, without any severe clinical-biological impairment and with a trend towards normalization.
