Laparoscopic mini/one anastomosis gastric bypass (MGB/OAGB) is an increasingly used bariatric surgical procedure. This surgical technique is effective in terms of both weight loss and the resolution of comorbidities, but it is not without complications. To report our experience in MGB/OAGB, assessing comorbidities and complications, and to illustrate post-surgical anatomy and radiological appearance of complications, a single-centre retrospective study of 953 patients undergoing MGB/OAGB between January 2005 and September 2018 was done. The inclusion criteria: body mass index (BMI) of 40 kg/m2 or higher or BMI between 35 and 40 kg/m2 with significant comorbidities not responsive to medical therapies. In the postoperative period, all patients were evaluated with clinical and laboratory tests and radiological examinations (upper gastrointestinal series, computed tomography and magnetic resonance imaging). Median weight was 126.69 kg and mean BMI was 49.4 kg/m2. Regarding comorbidities, 37.2%, 52.8%, 46.7% and 43.2% of patients presented with preoperatively diagnosed type 2 diabetes mellitus (T2DM), hypertensive disease, dyslipidaemia and obstructive sleep apnoea syndrome (OSAS), respectively. Median excess weight loss at 6, 12, 24 and 60 months after surgery was 33.45%, 53.81%, 68.75% and 68.80%, respectively.

Abstract

Laparoscopic mini/one anastomosis gastric bypass (MGB/OAGB) is an increasingly used bariatric surgical procedure. This surgical technique is effective in terms of both weight loss and the resolution of comorbidities, but it is not without complications. To report our experience in MGB/OAGB, assessing comorbidities and complications, and to illustrate post-surgical anatomy and radiological appearance of complications, a single-centre retrospective study of 953 patients undergoing MGB/OAGB between January 2005 and September 2018 was done. The inclusion criteria: body mass index (BMI) of 40 kg/m2 or higher or BMI between 35 and 40 kg/m2 with significant comorbidities not responsive to medical therapies. In the postoperative period, all patients were evaluated with clinical and laboratory tests and radiological examinations (upper gastrointestinal series, computed tomography and magnetic resonance imaging). Median weight was 126.69 kg and mean BMI was 49.4 kg/m2. Regarding comorbidities, 37.2%, 52.8%, 46.7% and 43.2% of patients presented with preoperatively diagnosed type 2 diabetes mellitus (T2DM), hypertensive disease, dyslipidaemia and obstructive sleep apnoea syndrome (OSAS), respectively. Median excess weight loss at 6, 12, 24 and 60 months after surgery was 33.45%, 53.81%, 68.75% and 68.80%, respectively. The remission of comorbidities was 91.4% for T2DM, 93.7% for hypertensive disease, 90.3% for dyslipidemia and 93.4% for OSAS. Early and late complication rates identified with radiological examinations were 1.5% and 1.6%, respectively. MGB/OAGB was effective for weight loss and comorbidities remission. Complications occurred at lower rate than with other surgical procedures were identified with imaging; CT was the main radiological technique.
