The operational impact of LSG has not been described in the literature. Early, non-randomized data suggest that LSG is efficacious in the surgical management of morbid obesity (8). However, it is not clear if weight loss following LSG is sustained long term and therefore, it is not possible to determine what percentage of patients may require additional revisional surgery following LSG. The operational impact of LSG as a staged or definitive procedure is poorly defined and must be analyzed further to establish its overall health care costs and operational impact. Although LSG is a promising treatment option for patients with morbid obesity, its role remains undefined and it should be considered an investigational procedure that may require revision in a subset of patients (9).
