• Bariatric surgery has been widely performed for more than 20 years without any clinical evidence of life survival improvement in operated obese vs non-operated, even if it officially started in 1991 (NIH)
• Since 1998 (Noya – Sassari) 16 clinical studies regarding BMI<35 Pts have been published. These papers show a good weight loss in these pts and a significant improvement of DM2, with a rate of mortality of 0.29% and complications of 4%.

• SG pts showed a quicker weight loss compared to GBP pts (better %EWL at 6months and 1 year) but comparable at 2 and 3 years
• SG and GBP pts showed a better weight loss compared to LAGB pts (p=.001)

RESULTS
• 36 Pts with BMI< 35 underwent LASGB • 5M/31F; mean age: 36±10 yo; mean
preoperative BMI was 32.7±1 (range 30-34.9)
• 30-days mortality, intraoperative complications and laparoscopic conversion were absent
• 3 Pts were debended for gastric pouch, 1 was converted to sleeve gastrectomy

DM2 in BMI<35 PtsS.Giovanni Bosco Experience
• 2Pts submitted to LRYGBP – (1M/1F) 44+/-2,8y; preop BMI 34,6+/-0.14
• One suffered from DM2 since >10 years and was under insuline therapy (>80 U/day) with good glycemic control (HbA1c 6,8%)
• At 2 years she improved DM2 with HbA1c 6,8% with 3 gr of metformin/day and BMI 28
• One male pts was on metformin since 3 years with good glycemic control (HbA1c 6,1%) and after 4 years he is in good glycaemic control (HbA1c 5,6%) in absence of therapy
DM2 in BMI<35 PtsS.Giovanni Bosco Experience
• 2Pts submitted to SG – (1M/1F) 45+/-5y; preop BMI 33,8+/-0.3– Both two Pts were under metformin Therapy
(one since 1,5 years and one since 8 years) with good glycaemic control (HbA1c 6.6+/-1%)
– At 18 months after surgery they were 21,5+/-0,5 Kg/m2 with good glycaemic control (HbA1c 5,6+/-0.3%) in absence of therapy.
CONCLUSIONSCONCLUSIONS• Patients with BMI 30-35 can be submitted to LAGB, SLEEVE
e LRYGB as a tailored, safe and effective approach to lose weight at short term follow-up
• Short-term weight loss of BMI<35 SG patients is comparable to GBP patients and better than LAGB patients
• SG could improve bariatric comorbidities such as DM2 in low BMI pts.
