Dyslipidemia is known to increase significantly the odds of major cardiovascular events in the general population. Its control becomes even more important in the type 2 diabetic (T2DM) population. Bariatric surgeries, especially gastric bypass, are effective in achieving long-term control of dyslipidemia in morbidly obese patients.


The objective of the study was to evaluate the control of dyslipidemia in patients with T2DM and BMI below 30 that were submitted to the laparoscopic ileal interposition associated to sleeve gastrectomy.


An observational transversal study was performed in a tertiary care hospital, between June 2005 and August 2007. Mean follow-up was 24.5 months (range 12–38). The procedure was performed in 72 patients: 51 were men and 21 were women. Mean age was 53.1 years (38–66). Mean BMI was 27 kg/m2 (22.1–29.4). Mean duration of T2DM was 10.5 years (3–22). Mean HbA1c was 8.5%. Hypercholesterolemia was diagnosed in 68% of the patients and hypertriglyceridemia in 63.9%.


Mean postoperative BMI was 21.2.kg/m2 (17–26.7). Mean postoperative HbA1c was 6.1%, ranging 4.4% to 8.3%. Overall, 86.1% of the patients achieved an adequate glycemic control (HbA1c < 7) without anti-diabetic medication. HbA1c below 6 was achieved by 50%, 36.1% had HbA1c between 6 and 7, and 13.9% had HbA1c above 7. Total hypercholesterolemia was normalized in 91.8% and hypertriglyceridemia in 89.1% of patients. Low-density lipoprotein below 100 mg/dl was seen in 85.7%.


The laparoscopic ileal interposition associated to sleeve gastrectomy was an effective operation for the regression of dyslipidemia and T2DM in a non-obese population.
