Bariatric surgery in obese patients is linked to a more frequent remission of diabetes and less complications than those who received habitual attention, according to a long -term follow -up study of obese people with type 2 diabetes published in the latest edition of theJama Magazine, in a thematic number about this disease.
Several studies show that type 2 diabetes can be prevented by reducing the incidence of this pathology by up to 50 % with lifestyle and pharmacological interventions.
Short -term investigations have detected that the results of bariatric surgery help the remission of diabetes, but no long -term results of this operation were known in the remission of diabetes and the complications linked to this pathology.
Lars Sjostrom, from the University of Gothenburg, in Sweden, and his colleagues carried out a follow -up of the Swedish Obese Subjects (SOS) study, held in 25 surgery departments and 480 primary care centers in Sweden.Of the patients recruited between September 1987 and January 2001, 260 of the 2,037 members of the control group and 343 of 2,010 bariatric surgery patients had type 2 diabetes at the beginning of the study.
Due to diabetes complications, the average monitoring time was 17.6 years in the control group and 18.1 years in the surgery group.The proportion of patients in remission, defined as blood glucose and without medications for the disease, after two years was 72.3 % in the surgery group and 16.4 % in the control group.
After 15 years, diabetes remission rates were reduced by up to 30.4 % for bariatric and 6.5 % surgery patients for control patients.
All types of bariatric surgery (adjustable or non -adjustable gastric band, gastric bypass or gastroplasty with vertical band) were related to higher remission rates compared to usual attention.
In addition, bariatric surgery was linked to a decrease in the incidence of microvascular and macrovascular complications."In this very long -term observational follow -up study of obese patients with type 2 diabetes, bariatric surgery was associated with the remission of the most frequent diabetes and less complications than usual care. These results require confirmation in random trials," they haveconcluded the authors.
