Abstract

Introduction: In 2018, sleeve gastrectomy was the most common bariatric procedure performed in the USA,
accounting for 61.4% of all procedures. Nevertheless, more than half of the patients who underwent primary
restrictive bariatric procedures like Laparoscopic Adjustable Gastric Banding (LAGB) and Laparoscopic Sleeve
Gastrectomy (LSG) experience failure in achieving or maintaining weight loss. Therefore, Revisional surgeries are
needed to overcome this failure.
Aim of work: The aim of current study was to assess effectiveness of one anastomosis gastric bypass (OAGB) as
a revisional surgery after failed LSG regarding weight loss, EWL, TBWL, complication rate, and remission of obesity
related morbidities.
Patients and methods: We included 83 patients with failed weight loss after single previous laparoscopic sleeve
gastrectomy who underwent OAGB as a revisional surgery.
Results: the mean %TBWL was 33.3, 39.9 and 42.1 at 12, 26 and 36 months of follow up. Postoperative
complications rate was 10% (Bleeding, Wound infection& RTI) (2.5%, 2.5% & 5%). There was a 61.8% full
remission of Dm & HTN.
Conclusions: This study suggest OAGB is an effective revisional bariatric surgery for patients who didn’t reach
sufficient loss of weight loss or maintain their weight after failed laparoscopic sleeve gastrectomy with higher rates
of weight loss and lower rates of early complications.
