One Anastomosis Gastric Bypass/Minigastric Bypass in Patients with BMI < 35 kg/m and Type 2 Diabetes Mellitus: Preliminary Report.

INTRODUCTION

Obesity in the world has been increasing, and the number of diabetic patients will increase by 114%, and the best treatment results are achieved through surgery. Several techniques have been described; the gastric bypass of an anastomosis (MGB/OAGB) has been gaining popularity for its simplicity and good results. We present a prospective study with this technique in 16 mild obesity patients with type 2 diabetes mellitus or peripheral insulin resistance.

OBJECTIVE

To evaluate weight loss as well as metabolic changes by measuring fasting glycemia and Hb A1c after 1 year of follow-up.

MATERIAL AND METHODS

Sixteen patients were operated on with the OAGB/MGB technique from September 2014 to January 2016, with some form of metabolic syndrome, whether DM2, RPI, HBP, or dyslipidemia, including patients in the study with a follow-up of at least 12 months.

RESULTS

There were 13 cases of female sex and 3 of male, average age of 42.9 years, with an average weight of 87.7 kg and BMI of 32.2 kg/m. Metabolic values were fasting glycemia of 193.6 ± 52.9 mg/dl and HbA1c of 8.4% ± 1 (preop) and glycemia posop, 78.8 ± 7.6 mg/dl; HbA1c posop, 6.1 ± 0.2; preop weight, 87.7 ± 14 kg (69-116); weight posop, 66.8 ± 10.5 kg (49-90); BMI preop, 32.2 ± 1.8 (30-34.9); BMI posop, 25.4 ± 1.7 (21.7-27.6); percentage of excess weight lost, 87.6 ± 11.8 (70.9-100) % with 100% remission of diabetes.

CONCLUSION

The results show the benefits of MGB/OAGB in mild obese diabetic patients.
