Background
Recent data demonstrates that laparoscopic adjustable gastric banding (LAGB) is found to be associated with high rates of weight loss failure and long-term complications. Therefore, the search for the optimal revisional bariatric procedure is ongoing.
Objective
We aim to assess the safety and efficacy of converting a failed LAGB to laparoscopic one anastomosis gastric bypass (OAGB) as a revisional procedure.
Setting
Large, metropolitan, tertiary, university hospital.
Methods
Retrospective review of patients who underwent OAGB after LAGB.Demographics, comorbidities, BMI before and after the procedure, complications, and length of stay were documented.
Results
Fifty-seven patients underwent OAGB after LAGB. For 41 patients, the band was removed, and an OAGB was performed in a single procedure (71.9%), and 96.5% of the cases were completed laparoscopically. Postoperative complications occurred in 9 patients (15.7%), including one mortality. Average BMI decreased from 42.8 ± 7.0 to 31.3 ± 5.2 kg/m2 at least 1 year after surgery, representing a mean %EWL of 64.5%. There was no statistical difference in complication rates between the 1-stage and 2-stage approach.
Conclusions
Conversion of a failed LAGB to OAGB is effective but carries higher complication rates. Randomized controlled studies comparing different procedures are necessary to further clarify the optimal revisional bariatric operation.
