CONTEXT About 5% of the US population is morbidly obese. This disease remains largely refractory to diet and drug therapy, but generally responds well to bariatric surgery. OBJECTIVE To determine the impact of bariatric surgery on weight loss, operative mortality outcome, and 4 obesity comorbidities (diabetes, hyperlipidemia, hypertension, and obstructive(More)

BACKGROUND Health insurance payors harbor concerns regarding the cost of bariatric procedures that are chiefly related to early readmissions and reoperations. We have attempted to identify the avoidable causes of readmission. METHODS We retrospectively reviewed the indications for short-term (<90-d) emergency department (ED) visits, readmissions, and(More)
BACKGROUND AND OBJECTIVES Complications resulting in hospital readmission are important concerns for those considering bariatric surgery, yet present understanding of the risk for these events is limited to a small number of patient factors. We sought to identify demographic characteristics, concomitant morbidities, and perioperative factors associated with(More)
