Bariatric surgery: three surgical techniques, patient care, risks, and outcomes.

The prevalence of obesity in the United States is a serious health concern. Bariatric surgery is a recognized and accepted approach for addressing weight loss and health conditions that occur as a result of morbid or severe obesity. Lifestyle changes, dietary modifications, and regular exercise are required for optimal and lasting surgical weight loss. Perioperative care of bariatric patients requires the use of interventions that differ from those used for nonobese patients, including bariatric-specific equipment, intraoperative monitoring of blood glucose, and postoperative monitoring for respiratory compromise. This articles outlines the risks and typical outcomes associated with three common bariatric procedures-laparoscopic adjustable gastric banding, laparoscopic sleeve gastrectomy, Roux-en-Y gastric bypass-to help perioperative nurses and other health care providers successfully advise patients and monitor their care for optimal outcomes.
