Morbidity and effectiveness of laparoscopic sleeve gastrectomy, adjustable gastric band, and gastric bypass for morbid obesity.

LSG, LAGB, and LRYGB are all safe and effective modern surgical options for the treatment of morbid obesity. Recent quality improvement successes in bariatric surgical care delivery have resulted in low mortality and morbidity after these procedures. All seem to result in sustained weight loss and improvement in weight-related comorbidities, although appropriate long-term outcomes data for all procedure types are needed. The LRYGB seems to be associated with the most risk but offers the most benefit, whereas the LAGB seems to have the lowest risk and to be least effective. The LSG seems to be positioned between the LRYGB and LAGB in associated morbidity and effectiveness in short-term and medium-term studies. Because the LSG has only recently been performed, there are currently no data about its long-term effectiveness. A better understanding of the unique risk/benefit profile associated with each procedure type will better inform patient selection and has the potential to further optimize outcomes.
