Midterm outcomes of one anastomosis gastric bypass for patients with BMI < 35 kg/m from a large single center.

Background: One-anastomosis gastric bypass (OAGB) is gaining more attention in patients with severe obesity and recently is used for patients with body mass index (BMI) < 35 kg/m. In this 5-year single center experience we aim to report our outcomes of using OAGB for patients with BMI < 35 kg/m.

Methods: This is a retrospective analysis of prospectively collected data recorded in to our national obesity registry database.

One anastomosis gastric bypass as a one-stage bariatric surgical procedure in patients with BMI ≥ 50 kg/m.

In patients with BMI ≥ 50 kg/m, it is difficult to select an appropriate procedure that can lead to optimum results. This study aims to evaluate mid-term weight loss outcomes in patients with BMI ≥ 50 kg/m following one anastomosis gastric bypass (OAGB) as a one-stage procedure. A prospective study was conducted on patients with BMI ≥ 50 kg/m, aged 18 years and above who had undergone primary OAGB from January 2016 to February 2019 with at least two years follow-ups.

Phlegmon Formation due to Perforated Marginal Ulcer After One Anastomosis Gastric Bypass; Conversion to Roux-en-Y Gastric Bypass: a Video Case Report.

One anastomosis gastric bypass is now an accepted bariatric procedure in many countries. A rare but serious complication of OAGB is perforation of marginal ulcer with 0.5-1% incidence that needs urgent diagnosis and intervention.

Laparoscopic resection of gastric duplication cyst containing gastrointestinal stromal tumour: A case report.

Gastric duplication cyst (GDC) in adults is an extremely rare congenital anomaly. Here, we report the case of a GDC containing gastrointestinal stromal tumour (GIST) in a 60-year-old male patient who presented with abdominal pain. Laparoscopic resection with safe margins was performed following endosonographic localisation of the lesion.

Laparoscopic Roux-en-Y gastric bypass in intestinal non-rotation.

There are some incidental findings during bariatric surgery. Some of these findings may make the operation more challenging than routine surgery. Intestinal malrotation/non-rotation are rare congenital anomalies that may remain asymptomatic until bariatric surgery.
