Description of the operation
The "Duodenal Switch" (DS) is a variation of the biliopancreatic diversion (diversione biliopancreatica ), and forms part of the so-called "malabsorbitives", consisting of a partial reduction of stomach volume and in the covering of an internal intestinal derivation.
It can also be done in two time periods; first the stomach is reduced and, after an important weight loss, at the 6 - 12 stage, the intestinal derivation is done.
A malabsorbment is thereby provoked of some principal nutrients, especially fats.
For whom it is required
It is indicated for patients who have a BMI greater than 50, for patients affected by bulimia or other serious eating disturbances, and in the case of pathologies related to very serious obesity.
The results
The results are similar to those of the biliopancreatic diversion according to Scopinaro: the percentage of excess weight loss can reach over 80%
It involves an invasive operation that is not completely reversible and that may cause over time even serious nutritional shortages if eating is not supported regularly by appropriate integrators.
The checks
The checks to be carried out after the biliopancreatic diversion are at 1, 3, 6 and 12 months from the operation; subsequently they become annual and are performed by the surgeon, and/or medical dietician; the psychologist intervenes when necessary.
Some blood sample tests are programmed at different stages to check for possible nutritional shortages.
Integrative therapy is employed constantly and for an indeterminate period.
